Chairman, China Energy Storage Alliance (CNESA)
Director, Institute of Engineering Thermophysics, Chinese Academy of Sciences

According to data from the National Development and Reform Commission (NDRC), China's nationwide installed capacity of new-type energy storage has exceeded 100 GW, more than 30 times the level at the end of the 13th Five-Year Plan period.

Driven by Three Forces, the Energy Storage Market Reaches

a New Milestone

This development is the result of the combined effects of multiple key factors, including market demand, technological breakthroughs, and policy support.

First, rigid demand from the energy transition. Driven by China's “dual carbon” goals, installed capacity of renewable energy such as wind and solar has grown rapidly. Due to the intermittency and instability of renewables, their high penetration has significantly increased pressure on grid integration. As a key solution for renewable energy grid connection, energy storage has therefore seen a sharp rise in market demand.

Second, continuous breakthroughs in energy storage technologies. After a long period of accumulation, decisive breakthroughs have been achieved over the past five years. Lithium-ion battery technologies have continued to advance, enabling large-scale production of storage batteries. System performance has improved significantly while costs have continued to decline. At the same time, other technology pathways such as compressed air energy storage and flow batteries are gradually being commercialized, laying a solid foundation for large-scale deployment.

Third, strong support from the policy framework. At the national level, a series of major policies have been introduced to support industry development. These include the Guiding Opinions on Accelerating the Development of New Energy Storage issued by the NDRC and the National Energy Administration, and the Opinions on Improving the Price Governance Mechanism issued by the General Office of the CPC Central Committee and the State Council. By advancing and refining pricing mechanisms and market rules, these policies provide a clearer market environment for energy storage projects. Local governments have also introduced specific market and pricing policies tailored to their development characteristics, greatly stimulating the enthusiasm of market participants.

Based on current trends, the author believes that over the next three to five years, both the pace and scale of development of the new-type energy storage market will continue to increase significantly.

First, demand for energy storage will continue to rise. As renewable energy installations keep expanding, the role of energy storage will become increasingly prominent, driving rapid growth in demand.

Second, policy support will remain strong. A series of national policies have been introduced to promote the development of the energy storage industry. The Action Plan for the Large-Scale Construction of New-Type Energy Storage (2025-2027) proposes that by 2027, China's installed capacity of new-type energy storage will exceed 180 GW, driving approximately RMB 250 billion in direct project investment. This has effectively boosted market expectations. In addition, in September this year, China announced a new round of Nationally Determined Contribution (NDC) targets, clearly stating that by 2035, total installed capacity of wind and solar power will exceed six times the 2020 level, with a target of reaching 3.6 TW. To meet these goals, strong national support for energy storage is expected to continue.

Third, technological progress and cost reductions will continue. With ongoing innovation and scaling-up of energy storage technologies, new technologies and products will continue to emerge, while there remains room for further cost reductions at the system level.

Fourth, business models will gradually mature, with diversified revenue streams including capacity payments, spot market arbitrage, and ancillary services.

Fifth, overseas market demand remains strong. As the share of renewable energy generation continues to increase globally and supportive policies are introduced in many regions, further improvements in the economics of energy storage are expected to drive continued expansion of overseas markets.

According to forecasts by the Zhongguancun Energy Storage Industry Technology Alliance, new-type energy storage will reach the next “100 GW” milestone in 2027-2028, with China's installed capacity reaching 200 GW. Around 2030, China is expected to reach the third “100 GW” milestone, with cumulative installed capacity reaching 300 GW.

How to Shift from “Scaled Deployment” to “High-Quality Operation”?

However, to achieve a transition to high-quality operation over the next one to two years, concentrated breakthroughs are still needed in key areas such as market mechanisms, technological optimization, safety risk prevention, and full life-cycle management.

In terms of market mechanisms, it is necessary to gradually improve market and pricing mechanisms for new-type energy storage, promote the business model of “capacity payments + energy arbitrage + ancillary services,” appropriately expand spot price spreads, incorporate new types of ancillary services-such as ramping, inertia, reserves, and black start-into the pricing mechanism, and promote linkage between green power trading and energy storage discharge volumes to realize explicit monetization of environmental attributes.

In terms of safety risk prevention, a solid safety defense must be built from three aspects: monitoring and early warning, protection mechanisms, and standards and regulations. A unified system of safety technical standards should be established rapidly, clearly defining safety indicators for equipment selection, installation and commissioning, operation, and maintenance of energy storage power stations. Research should also be conducted on implementing a battery traceability system to ensure accountability for safety responsibilities.

In terms of technological R&D, first, continued strong development of lithium batteries is needed, with further optimization of the operation and application of existing lithium-based energy storage systems. Second, priority should be given to promoting demonstration and application of long-duration energy storage technologies such as variable-speed pumped storage, compressed air energy storage, and flow batteries. Greater efforts should also be made to advance R&D and validation of new technologies such as solid-state batteries, sodium-ion batteries, and grid-forming energy storage, fostering a development pattern in which multiple storage technologies progress in coordination.

In terms of industrial coordination, efforts should be made to enhance self-sufficiency in key materials. Targeting weak links such as core materials for energy storage cells and key equipment for long-duration storage, breakthroughs should be pursued through industry-university-research innovation consortia. Industrial development order should be standardized by curbing inefficient and repetitive construction through dynamic monitoring of project filings, and guiding capital toward projects with high utilization rates and high safety performance.

To promote the healthy and sustainable development of the industry, the author believes that further policy efforts are needed. First, market-based revenue policies should be improved by further refining energy storage pricing mechanisms, clarifying pricing calculation rules for different regions and application scenarios, expanding revenue channels from ancillary services, and smoothing cost-sharing mechanisms for such services, while continuing to promote business models involving capacity prices, energy prices, and ancillary services.

Second, full-chain safety policies should be strengthened by improving safety standards and regulations, refining safety supervision processes, implementing regular safety inspection systems, and clearly defining safety acceptance standards for all stages of energy storage power stations, from design and construction to operation and maintenance.

Third, research on energy storage pricing should be conducted by promoting cost tracking for major mainstream energy storage technologies, studying cost structures across key segments of energy storage systems, and guiding the industry toward rational assessments of energy storage costs.

Finally, industry self-regulation should be promoted by strengthening dynamic monitoring of data such as energy storage output, continuously paying attention to industry development issues, advancing technological iteration and safety performance upgrades of energy storage products, supporting industry-led self-regulatory initiatives, and guiding the sector toward a virtuous development path that emphasizes safety performance and value creation.

A trio of German grid-scale BESS news items, with Next Kraftwerke and ju:niz Energy agreeing a seven-year toll, Alpiq announcing a 370MW pipeline, and WBS Power selling the country’s largest solar-plus-storage project and planning a data centre on the same site.

Germany has this year become a hotbed of battery energy storage system (BESS) project announcements and deal-making, driven by its substantial revenue opportunities as Europe’s largest electricity market and a looming August 2029 deadline for getting projects operational to avoid charge-discharge grid fees. See all recent coverage here.

WBS Power sells solar-plus-storage project, plans data centre

Developer WBS Power has sold the 150MW solar, 500MW/2,000MWh BESS Project Jupiter in Brandenburg, Germany, to investor Prime Capital.

WBS acquired the site for the clean energy project in 2022, and the project will require €500 million (US$583 million), with construction expected in late 2026/early 2027. Both technologies will share a 380kV grid connection in the area of TSO 50Hertz. The acquisition is subject to Project Jupiter reaching ready-to-build (RTB) status.

The transaction also establishes a joint venture to co-locate a hyperscale data centre of up to 500MW in power demand in the same area.

WBS Power said there is growing demand for data centres in Germany, which are highly energy-intensive and benefit significantly from direct access to renewable power and grid stability.

“By integrating Germany’s largest co-located BESS and Solar PV project with a hyperscale data center, we are creating a unique platform that supports both the energy transition and digital transformation,” said Maciej Marcjanik, CEO of WBS Power Group.

Alpiq secures 370MW Germany pipeline

Switzerland-based energy firm Alpiq has expanded in Germany with a 370MW BESS pipeline the company has ‘secured’, in partnership with developer SPP Development. The projects in Brandenburg and Saxony-Anhalt are expected to reach RTB status in 2026.

Lukas Gresnigt, Head International and member of the Executive Board of Alpiq said that Germany is a competitive and complex market for BESS, with many projects are queuing for grid access and permits, and the partnership combined Alpiq’s financial strength and SPP’s local expertise.

Last week, Energy-Storage.news reported on Alpiq entering into a long-term toll for a BESS in Germany owned and operated by Eco Stor. Alpiq has acquired projects in France and Finland, where it recently commissioned a 30MW/36MW project.

Shell and EQT companies agree Germany BESS toll

VPP operator Next Kraftwerke, acquired by Shell in 2021, has concluded a Germany BESS toll with BESS platform ju:niz Energy, acquired by investor EQT in 2024.

The seven-year toll is for a 20MW/40MWh project in Vöhringen, Bavaria, and Next said it is one of the first operational contracts of its kind in Germany, live since 1 November.

Next Kraftwerke will pay ju:niz Energy a fixed monthly fee per installed MW for the use of the BESS capacity. The model offers stable revenues for the operator (ju:niz) and flexibility for the optimiser (Next Kraftwerke). The toll is 80% fixed remuneration and 20% merchant, Next said.

“15th Five-Year Plan” Proposal Mentions for the First Time: Building an “Strong Energy Power”

CNESA Admin

December 4, 2025

Source: People's Daily

Building a strong energy power is essential for balancing domestic and international factors, development and security, and advancing Chinese-style modernization. It is a systematic project that requires adhering to the principle of establishing the new before phasing out the old and making progress while ensuring stability.

A close reading of the “15th Five-Year Plan” proposal reveals 16 national “strength-building” goals. Among them, the term “Strong Energy Power” appears in the plan proposal for the first time - what is the significance behind this?

Building a strong energy power is a practical necessity for coordinating domestic and international dynamics, harmonizing development and security, and advancing Chinese-style modernization.

Looking outward, the global energy supply-demand landscape is undergoing profound adjustments. Geopolitics, climate change, and energy transition are interacting with each other, making energy issues a top priority in national security for countries around the world.

Looking inward, during the “15th Five-Year Plan” period, China's energy consumption will continue to grow rigidly, with an estimated annual increase of about 600 billion kWh in electricity demand - representing considerable pressure. As a major country with over 1.4 billion people, China cannot repeat the high-consumption, high-emission path taken by developed nations. Instead, it must move onto a green and low-carbon development trajectory.

Therefore, building a strong energy nation means constructing a robust energy industrial chain, supply chain, and innovation system; upholding a diversified energy mix across wind, solar, hydro, nuclear and more; continuously increasing the share of new energy supply; safely and orderly replacing fossil energy; and transforming energy production and consumption patterns. Only by strengthening such foundational capabilities and enhancing self-reliant development capacity can China build greater confidence and advantage in international competition.

China already possesses many favorable conditions for becoming a strong energy nation. During the “14th Five-Year Plan” period (2021-2025), China consolidated its position as the world's largest energy producer, with an energy self-sufficiency rate above 80%. As fossil energy consumption peaks sequentially, dependence on imported oil and gas will gradually fall to a reasonable level. China has also built the world's largest and most complete new energy industry chain, supplying over 80% of global solar PV modules and 70% of wind power equipment. Many energy technologies and equipment lead globally, with new breakthroughs in million-kilowatt-class hydropower, advanced nuclear power, heavy-duty gas turbines, smart grids, and more.

As the world's largest developing country, China still faces heavy tasks in economic development and improving people's livelihoods, and its energy development is subject to many hard constraints. During the “15th Five-Year Plan” period (2026-2030), building a strong energy nation will remain a systematic endeavor that requires adhering to establishing the new before phasing out the old, advancing steadily, and carefully balancing several key relationships.

The relationship between energy security and energy transition.

The green transition cannot be achieved overnight. It must proceed steadily based on national conditions. Traditional energy must be phased out in an orderly manner, while new energy must be established first, early, and rapidly to enable safe and reliable substitution.

The relationship between energy development and energy conservation.

Building a strong energy nation requires strengthening the supply side by promoting green energy development; however, the demand side must not be overlooked. Improving energy efficiency and promoting green, low-carbon production and lifestyles are also essential. For example, through large-scale equipment renewal campaigns, China replaced over 20 million units (sets) of equipment in key sectors in 2024, achieving approximately 25 million tonnes of standard coal in energy savings - reducing carbon emissions at the source.

The relationship between government and market.

China will deepen market-oriented reforms in competitive segments of the energy sector, continuously improve the energy pricing mechanism, and stimulate endogenous motivation and innovation vitality.

During the “15th Five-Year Plan” period, China will accelerate the development of a clean, low-carbon, safe, and efficient modern energy system. More wind, sunshine, and water will be transformed into green development power, and fossil energy will be used more cleanly and efficiently, strengthening the stable and healthy development of China’s energy.

Cache Power Plans ‘Canada’s First’ Commercial-Scale Compressed Air Energy Storage Facility

CNESA Admin

December 4, 2025

Projects

Source: Energy Storage News

Compressed air energy storage (CAES) developer Cache Power is partnering with construction company EllisDon to deliver a CAES facility in Northeast Alberta, Canada.

The facility will be constructed in two phases and located next to the Marguerite Lake substation to enhance efficiency and facilitate grid integration.

Cache Power does not have any information on its website, but appears to be a special purpose vehicle (SPV) for Federation Engineering.

On Federation’s website, the company clarifies that the Marguerite Lake facility will have a 250MW load capacity and 640MW generation capacity. Energy storage capacity or planned duration were not referred to in publicly available materials.

The companies assert that the technology will be essential in stabilising Alberta’s grid and supporting both provincial and national efforts toward a net-zero electricity future. The project has secured all key regulatory approvals, with early construction scheduled to start soon.

CAES technology operates by pressurising and directing air into a storage medium to load the system. When discharging, the stored air is released through a heating system to expand, driving a turbine generator.

Notably, the companies claim the project will be the first commercial scale CAES facility in Canada.

Ontario-headquartered Hydrostor is known for its advanced compressed air energy storage (A-CAES) projects.

A-CAES operates similarly to traditional CAES but captures heat from the compressor and passes it through heat exchangers to store in pressurised water. This water is kept in a reservoir and then released into a cavern to displace air during discharging, a process known as hydrostatic compensation.

In conventional CAES, less than 50% of the energy can typically be recovered. The thermal energy produced during compression is often wasted, and the power output varies depending on the residual underground air pressure.

Hydrostor has two small operational projects in Canada, one a pilot and the other a commercial demonstrator, with the larger one being a 2.2MW/10MWh commercial system in Goderich, Ontario.

Hydrostor noted the Goderich Energy Storage Centre as the world’s first commercially contracted A-CAES facility. In addition to its role as technology provider, the A-CAES company is also developing large-scale projects around the world, including its 1.6GWh Silver City project in New South Wales, Australia, and 4GWh Willow Rock project in California, US. The company has secured some funding and offtake agreements for both, including a recent renegotiation of contracts for Willow Rock (ESN Premium article).

It has also proposed a 500MW/8,000MWh project in Ontario (ESN Premium), adjacent to Ontario Power Generation’s Lennox Generating Station in Greater Napanee.

Speaking with Energy-Storage.news, a representative from Federation clarified that the distinction between the CAES system titles for itself and Hydrostor came down to scale and usage.

Cache Power’s facility can store up to 48 hours of energy by compressing air with excess grid electricity and sequestering it in underground salt caverns formed through solution mining.

It can also blend up to 75% hydrogen with natural gas, with a future plan for complete hydrogen utilisation, aligning with Canada’s net-zero ambitions.

Power plant equipment supplier Babcock & Wilcox are collaborating on engineering the possible hydrogen facility expansion, employing the company’s BrightLoop technology.

Babcock & Wilcox claim that BrightLoop can produce hydrogen while isolating carbon dioxide for capture and storage.

Additionally, Cache Power states it will deliver economic and social advantages to the local community and Indigenous Partners. Cold Lake First Nations has actively engaged in the project’s development and is anticipated to collaborate as a partner with Cache Power in both the project and its operations.

Update: Jordan Costley, Director of Sustainability Projects at Federation Engineering, and President of Cache Power has clarified that the project will be 30.72GWh. Costley also added about CAES energy recovery:

“(The 50% recovery statistic) may have been true for the original D-CAES projects such as Huntorf (Germany 1978) and McIntosh (USA 1991) but our project is utilizing the latest D-CAES technology from Siemens Energy.“

“Today’s compression technology utilising multi-stage integrally geared and intercooled compressors is very efficient resulting in the heat of compression being low grade not valuable for thermal energy storage and reuse in the expansion process. The expander trains also include 90% effective dual-reheat recuperators again significantly increasing the overall efficiency. The technology we are utilizing is not “conventional CAES” as defined by Huntorf and McIntosh.

In Puerto Rico, the electric generation, transmission, and distribution facilities managed by PREPA are operated privately by Luma Energy. Both entities are overseen by the Puerto Rico Energy Bureau (PREB). Image: Trish Hartmann.

The Puerto Rico Energy Bureau (PREB) has issued a resolution and order requiring the Puerto Rico Electric Power Authority (PREPA) to complete the Accelerated Battery Energy Storage Addition Programme (ASAP).

The resolution and order require PREPA to finish the necessary review process with the Financial Oversight and Management Board (FOMB) concerning the four final agreements of the ASAP.

Implementation and delay of ASAP

In Puerto Rico, the electric generation, transmission, and distribution facilities managed by PREPA are operated privately by Luma Energy. Both entities are overseen by the Puerto Rico Energy Bureau (PREB).

ASAP aims to enhance grid reliability across the island by deploying utility-scale battery energy storage systems (BESS) alongside existing generation facilities.

Under the programme, independent power producers (IPPs) with existing power purchase and operating agreements (PPOAs) with PREPA will install BESS at their sites, “on an accelerated basis,” as stated in PREB documents available on the regulator’s website.

In 2024, PREB informed Luma Energy that its plan to contract with IPPs for BESS resources was consistent with public power policy.

In April 2024, Luma identified Phase 1 projects that could start immediately with minimal costs and no network upgrades, with some developers claiming they could be operational in less than 12 months and contracts expected to be executed by April 2025.

However, in August 2025, the projects remained stalled, with only one developer (Ecoeléctrica) responding to PREPA’s communications to say it was working to complete documentation by September, while three others (San Fermín, Horizon, and Oriana) did not respond at all.

PREB called the delays “extremely concerning” and required all four developers to provide detailed explanations for the lack of responsiveness, emphasising that these projects are crucial for addressing Puerto Rico’s electricity generation shortfall and warning that fines will be imposed if developers don’t comply with the information requests.

PREB issues resolution and order to PREPA

PREB concluded that Luma’s four final agreement terms for ASAP align with the island’s Energy Public Policy and the Integrated Resource Plan (IRP).

As a result, the Bureau approved the four drafts and directed Luma to finalise the contracts, submit them to PREPA’s Governing Board for approval, and demonstrate this process. Furthermore, PREPA was instructed to obtain approval from the FOMB.

On 20 November, Luma submitted final agreements to PREPA’s Board. The private operator asked for these documents to be confidential due to critical infrastructure, sensitive data, and personal information. PREB confirmed Luma’s compliance and granted confidentiality.

PREB clarified that the 1,500MW of battery storage listed in the IRP is a guideline, not a strict cap.

The resolution and order confirmed that this figure is not fixed and can be exceeded; battery projects in development will be assessed regardless of whether they propose more than 1,500MW of storage capacity. PREB also highlighted that any decision to increase or decrease this limit is solely at its discretion.

Because PREB has granted confidentiality to Luma, it is unclear for which participants the agreements have been submitted.

Developers Ecoeléctrica, San Fermín, Horizon, and Oriana have had ongoing communications with Luma. Though, as noted above, San Fermin, Horizon, and Oriana have previously failed to respond to PREPA’s communications.

Additionally, in August, Polaris Renewable Energy submitted a BESS standard offer (SO1) agreement on behalf of PREPA to PREB.

The SO1 agreement is included in the ASAP scheme. When submitted, Polaris appeared to distinguish itself from the other developers who had not delivered BESS projects on the island.

Included in the resolution and order, Commissioner Mateo Santos dissented in part and concurred in part, and stated:

“As I have previously expressed, I do not agree with the pass-through concepts included in the contracts under the ASAP programme, and therefore I dissent on that aspect. However, I concur with the Energy Bureau’s determination regarding the integration of battery energy storage resources.”

Santos continued, “Specifically, I agree with the Energy Bureau’s clarification that the approximately 1,500MW of Battery Energy Storage Resources identified in the Approved IRP’s Modified Action Plan constitutes a guideline rather than a fixed limit. Any final determination on the appropriate level of integration will be made by the Energy Bureau.”

The World Bank will invest in a huge 4GW, 5.12GWh solar-plus-storage complex in Malaysia, which will form part of a pan-Southeast Asian power grid initiative.

The Southern Johor Renewable Energy Corridor (SJREC) will be a roughly 2,000sqKm area dedicated to solar PV and energy storage capacity. The US$6 billion project is backed by the World Bank’s private investment arm, the Iternational Finance Corporation (IFC), alongside the state investment firm of Johor, Permodalan Darul Ta’zim (PDT), and Ditrolic Energy, a Malaysian integrated energy company.

The project is part of a number of larger schemes, chiefly the ASEAN Power Grid Initiative, a plan to integrate power grids and energy supply across Southeast Asian nations. In this vein, the SJREC will be part of the Johor–Singapore Special Economic Zone (JS-SEZ) “masterplan”, able to transmit clean energy to Singapore, which sits on Johor’s southern border.

As a densely populated city state, Singapore relies heavily on energy imports and has made significant plans for cross-border renewables transmission, perhaps most notably the mammoth AA PowerLink project in Northern Australia, which aims to deploy almost 20GW of solar capacity when fully operational and supply power to Singapore via undersea cables.

The site is also part of the Johor Green Development Policy 2030, which the state government introduced to expand its green industries and renewable energy developments.

“As the state agency entrusted to formulate the Johor Green Development Policy 2030, PDT is proud to witness our strategic framework transition into tangible reality today,” said Dato’ Ramlee bin A Rahman, president and group chief executive of Permodalan Darul Ta’zim.

“The Southern Johor Renewable Energy Corridor was conceived as the cornerstone of this policy, specifically Strategy one, to unlock the immense solar potential of the Kota Tinggi and Mersing districts.”

Tham Chee Aun, CEO of Ditrolic Energy, said the SJREC hub would “Anchor Johor’s clean energy export potential and provide a foundation for industries seeking renewable, low-cost power in the region.”

In an announcement, the IFC said the project would supply renewable energy to “local and multinational corporations, including hyperscale data centre operators, manufacturers, and other businesses in Johor”.

Renewables development is a major driver for meeting data centre power demand, primarily because of the affordability of solar projects and solar energy and the stability offered by coupling the technology with energy storage. In its most recent report, the International Energy Agency (IEA) said the world would become “thirsty for energy” in the coming years and that data centres were an “Important driver” of growing power demand.

Projects

Source: CCTV News

According to a report by CCTV News on December 1, China Green Development Group announced that a 200MW/800MWh semi-solid-state battery energy storage project located in Wuhai, Inner Mongolia, has been successfully connected to the grid. The project not only sets a new record for the installed capacity of grid-connected semi-solid-state lithium battery energy storage in China, but also marks a crucial step for China's semi-solid-state energy storage technology from pilot demonstration to large-scale commercial operation.

As a major new energy hub in northwest China, Wuhai city in the Inner Mongolia Autonomous Region, has leveraged its abundant wind and solar resources to consistently advance integrated development of “source-grid-load-storage” in recent years. This newly grid-connected energy storage facility serves as a core infrastructure project for enhancing local renewable energy consumption. Covering an area of about 100 mu (about 6.67 hectares), the project is equipped with 160 energy storage battery containers and 40 converter and booster integrated units.

Semi-Solid-State Lithium Battery Energy Storage Project Successfully Connected to the Grid in Wuhai, Inner Mongolia

Qin Lei, Project Manager of Wuhai Energy Storage Project, Inner Mongolia Branch, China Green Development Group:

“This massive ‘power bank’ utilizes domestically-developed semi-solid-state lithium iron phosphate battery technology, which offers significant advantages in safety performance, energy density, and cycle life compared with conventional liquid lithium iron phosphate batteries.”

With the rapid upgrade of the new energy industry, energy storage - essential for grid peak regulation, frequency modulation, and improving renewable energy utilization - is entering a phase of large-scale expansion. Semi-solid-state lithium battery technology represents a key direction for the future development of power and storage batteries. Using a hybrid solid-liquid electrolyte, semi-solid-state batteries retain the high ionic conductivity of liquid systems while achieving a cycle life exceeding 12,000 cycles, which greatly reduces lifecycle operational costs. In addition, they can effectively suppress lithium dendrite growth, further enhancing safety.

Liu Xiaofei, Assistant General Manager, Inner Mongolia Branch, China Green Development Group:

“Once fully operational, the project will feature a peak-shaving and frequency-regulating capability of 200MW/800MWh, providing 189,000 MWh of clean electricity to the grid annually. It enables flexible scheduling - storing energy during the day and supporting peak loads at night - significantly enhancing power system stability. It will also ensure that local green electricity can be fully delivered, stably transmitted, and efficiently utilized, solving key bottlenecks in regional renewable energy consumption.”

In recent years, semi-solid-state lithium batteries - offering both high safety and strong economic performance - have become a core direction of technological evolution in the energy storage sector. Previously, China's largest grid-connected semi-solid-state storage project had a capacity of 100MW/200MWh. The Wuhai project doubles that scale, demonstrating that China is now at the global forefront of large-scale applications of semi-solid-state energy storage technology.

European BESS news from project owners Premier Energy Group, Verbund, Eco Stor, Ingrid Capacity, Ric Energy, Ganfeng Lithium, EP Group, RWE and Giga Storage, securing acquisitions, financings and route-to-market (RTM) deals for multiple gigawatts of capacity this past week.

Romania: Premier buys 400MWh BESS, Verbund enlists

contractors for project

Energy firm Premier Energy Group has acquired a ready-to-build (RTB) 200MW/400MWh battery energy storage system (BESS) in Romania, near Iasi.

Construction on the project will start in 2026, with commissioning anticipated in late 2026 or early 2027. The project will support the integration or more renewables on Romania’s grid with fast-response capacity and grid balancing applications.

Premier is currently in advanced discussions on financing options for the project, with the expectation of securing a long-term structure, it said. The announcement did not say whether it was one of the winning projects from a recent EU-backed capex support scheme.

In related news, Austria-based utility and power firm Verbund’s local arm Verbund Wind Power Romania has enlisted OEM Prime Batteries and engineering firm Enevo Group to supply and integrate a 48MW/76MWh project.

It will be built at Verbund’s Alpha Nord Wind Farm in Tulcea County. The installation will help integrate more renewables but also improve the operational flexibility of the Verbund’s local renewable assets.

Prime Batteries Technology and Enevo Group will deliver the full engineering, procurement and construction (EPC) scope, including design, equipment supply, system integration, installation and commissioning.

Construction is scheduled to begin in February 2026 with commissioning set for September 2026.

Prime Batteries made headlines last year when it integrated a BESS for owner Monsson with an emphasis on locally manufactured technology.

Germany: Eco Stor project toll and Ingrid Capacity enters market

Project owner-operator and EPC Eco Stor has entered into a long-term toll with energy firm Alpiq for a 103.5MW/238 MWh BESS in Schleswig-Holstein, Germany.

Alpiq will partner with optimisers Enspired and Entelios to manage the BESS project’s activity in the electricity market.

It is Eco Stor’s second major grid-scale project in Germany, and identically sized to its first which came online in June this year, in Bollingstedt. The project with Alpiq in Schleswig-Holstein will come online in mid-2026.

The announcement coincided with one from Sweden-headquartered BESS owner-operator Ingrid Capacity, revealing it has partnered with developer Energiequelle for 200MW of grid-scale projects in Germany.

Energiequelle will develop the projects while finance, operate, and optimise the assets using its in-house trading and optimisation platform. The projects are expected to reach RTB in 2026. Ingrid has so far been active primarily in Sweden and Finland.

Italy: Ric Energy buys 200MW BESS

Spain-headquartered Ric Energy Group has acquired a 200MW BESS in the Apulia region of Italy. The firm’s development pipeline in Italy now stands at 942MW, it said announcing the post on LinkedIn.

It didn’t provide more details about the project in its post. Italy is currently a hotbed of activity, with the long-awaited first auction of its MACSE scheme concluded with 10GWh of BESS handed long-term revenue contracts. Many investors and owner-operators were waiting for the auction before taking FIDs and proceeding to construction.

Our publisher Solar Media will host the Battery Asset Management Summit Europe 2025 in Rome tomorrow and Wednesday (2 & 3 December), where MACSE and Italy will undoubtedly be big talking points.

Netherlands: Giga Storage toll with Vattenfall

BESS owner-operator Giga Storage has entered into a long-term toll with energy firm Vattenfall for its Project Leopard, a 300MW/1,200MWh BESS in the Netherlands.

The toll covers 100MW, one-third of Leopard’s total capacity. It will provide Giga with a fixed, long-term income stream that supports the project’s financing. Vattenfall will optimise the contracted portion of Leopard’s capacity for services such as grid stability, portfolio balancing, and electricity trading.

RTM deals for grid-scale BESS in the Netherlands are characterised by portioning a project’s capacity into different slices with different tollers and offtakers to spread risk, the same strategy adopted by other major BESS owner-operators there including Lion Storage and SemperPower.

UK: RWE to build 700MWh BESS, two optimisation deals announced

Germany-headquartered power firm RWE has made a final investment decision (FID) on a 350MW/700MWh BESS in Wales, called Pembroke Battery Storage. It is part of the wider Pembroke Net Zero Centre project combining renewable generation including green hydrogen production.

The project received planning consent in January 2025 and also won contracts in the UK’s most recent capacity market (CM) auction. Construction will start in 2026 with commissioning and commercial operation in H2 2028, ‘subject to receiving an updated and timely grid connection’, RWE said. That probably alludes to the ongoing grid connection queue reshuffle.

The news follows hot on the heels of two BESS optimisation announcements in the UK, both covered by our sister site Solar Power Portal.

China-based Ganfeng Lithium has enlisted power firm EDF to provide RTM and optimisation services for its 50MW/160MWh Kintore BESS project, while EP Group has contracted optimiser GridBeyond to do the same for its 50MW North Baddesley BESS.

At 19:18 on November 26, the battery cabin of the Diannong No.1 Energy Storage Station - part of the 200 MW / 400 MWh shared energy storage project by Ningxia Jiyang Green Storage - was successfully energized for the first time, marking the successful grid connection and commissioning of China's largest grid-side lead-carbon energy storage power station.

The Jiyang Green Storage 200 MW / 400 MWh shared energy storage project was invested and constructed by Ningxia Jiyang Green Storage Integrated Energy Services Co., Ltd. Covering an area of 55.4 mu (≈ 3.7 hectares) with a total investment of 620 million yuan, the project sets new records for the largest scale and highest power among grid-side lead-carbon energy storage stations. It is located in the core energy corridor of Xixia District, Yinchuan, and is equipped with 80 customized lead-carbon energy storage integrated cabins.

The system boasts a cycle life of over 6,000 cycles - 3 times that of traditional lead-acid batteries and 1.5 times that of lithium batteries - with a full life-cycle cost 40% lower than lithium batteries, making it the most cost-effective large-scale energy storage solution in China.

The State Grid Yinchuan Electric Power Company comprehensively tracked the project's construction progress, coordinated every step, and organized a professional technical team of dozens of staff from power dispatch, operation and maintenance, marketing, and information communications to provide grid connection services. The power dispatch control center assigned dedicated personnel for over 300 days of full-process monitoring. Under the overall deployment of State Grid Ningxia Electric Power Co., Ltd., both State Grid Yinchuan Electric Power Company and Ningxia Jiyang Green Storage actively coordinated to ensure the smooth grid connection of the Diannong No.1 Energy Storage Station.

“A successful grid connection of this project helps accelerate the integrated development of Yinchuan's energy storage industry and supporting clean energy sectors, enhances the grid's flexible regulation capability, increases renewable energy absorption, and eases peak electricity supply pressure. It also serves as an important demonstration for the integration of ‘generation-grid-load-storage’ and multi-energy complementarity,” said a relevant official from State Grid Yinchuan Electric Power Company.

The Australian government has officially opened the Capacity Investment Scheme (CIS) Tender 8, targeting 16GWh of energy storage capacity across the National Electricity Market (NEM).

The tender represents the largest single energy storage procurement under the CIS programme, reflecting the government’s accelerated deployment timeline for grid-scale storage infrastructure.

Tender 8 registrations opened earlier today (28 November) and will close on 23 January, with submissions closing on 6 February. The tender specifically targets energy storage projects with a minimum 4-hour duration requirement, emphasising the government’s focus on medium-duration storage technologies capable of providing extended grid support services during peak demand periods and renewable energy intermittency events.

The 16GWh capacity target represents a substantial increase from previous tender rounds and aligns with Australia’s expanded CIS target of a total 40GW of renewables and energy storage.

The tender incorporates streamlined assessment processes developed through previous rounds, building on reforms introduced when the government unveiled four tenders for 2025.

These process improvements aim to reduce assessment timeframes and provide greater certainty for project developers while maintaining rigorous evaluation criteria for technical capability, financial viability, and grid integration requirements.

Eligible technologies under Tender 8 include battery energy storage systems, pumped hydro energy storage (PHES), compressed air energy storage, and other proven energy storage technologies capable of meeting the 4-hour minimum duration requirement.

The tender excludes hybrid renewable energy projects, focusing exclusively on standalone energy storage systems that can provide grid services, including frequency regulation, voltage support, and energy arbitrage across multiple market timeframes.

The CIS has demonstrated significant success in previous tender rounds, with substantial energy storage capacity awarded across multiple procurement cycles.

Tender 3 resulted in over 15GWh of energy storage being awarded to successful applicants, while Tender 4 saw 11.4GWh of solar-plus-storage projects receive government support through the programme.

The scheme provides revenue support through Capacity Investment Scheme Agreements (CISAs) that supplement market revenues, enabling project developers to secure financing for energy storage projects that might otherwise face commercial viability challenges in merchant market conditions.

The support mechanism includes floor and ceiling price arrangements that provide revenue certainty while maintaining market exposure and incentives for efficient operation.

Tender 8 evaluation criteria encompass technical specifications, commercial arrangements, grid connection requirements and project development timelines.

Projects must demonstrate grid connection agreements or advanced connection applications with relevant transmission network service providers, along with evidence of site control, environmental approvals, and financial capacity to complete construction and commissioning activities.

The geographic distribution requirements under Tender 8 aim to ensure the deployment of energy storage across multiple states and regions within the NEM, thereby supporting grid resilience and renewable energy integration under diverse network conditions.

The scheme includes milestone requirements and progress reporting obligations to ensure that successful projects advance through the development, construction, and commissioning phases according to agreed-upon schedules.

The DCCEEW will conduct information sessions for potential applicants during December 2025 and January 2026, providing guidance on application requirements, evaluation criteria and commercial arrangements.

Successful Tender 8 projects are expected to be announced in mid-2026, with CISAs enabling project financing and construction commencement. You can find out more about CIS Tender 8 on the official website.

We caught up with the president of system integrator PotisEdge following news of its acquisition by Longi, which marks the Chinese solar PV giant’s move into the energy storage industry.

News of Longi’s acquisition of PotisEdge first emerged on 13 November, with a public notice on the Shaanxi Provincial Administration for Market Regulation website. It revealed that Longi Green Energy Technology has agreed to acquire c.62% of PotisEdge via an equity acquisition, capital increase and voting rights, giving it sole control of the firm. Prior to the deal, PotisEdge was 44.79% held by individuals.

Longi and PotisEdge are characterising the deal as a partnership via which Longi will launch its ‘Energy Storage One-Stop Solution’, as it now covers solar, hydrogen and energy storage. Longi said its energy storage solution will be deployed first in key markets such as the UK, Germany, Italy, and Spain.

Longi VP Dennis She said in the announcement: “The current development stage of the energy storage industry is very similar to the early days of solar — confidence-driven rapid growth, but also bringing disorderly competition. The future dimension of competition in energy storage has evolved from ‘having the technology’ to ‘value reliability.”

PotisEdge president: Combination will offer opportunities

Speaking to Energy-Storage.news at an event in London marking the deal, PotisEdge founder and president Minjie Shi said: “Longi will bring the strong brand name and a big market to PotisEdge, and the combination of the two companies offers big opportunities to the market.”

“We are a technology company that designs and manufactures all the key components with the exception of the battery cells. We’re highly integrated, and that’s allowed us to gain a good reputation and solve market challenges,” Shi said.

“Battery cell manufacturing and system integration are totally different. Battery cells are a chemistry process, system integration is about controls, software, hardware and intelligent systems.”

Core technology offering

The firm’s offering is built around the five ‘S’s: BMS (battery management system), EMS (energy management system), PCS (power conversion system), TMS (thermal management system) and its proprietary ICCS (intelligent cell contact system) technology for predicting thermal runaway.

In September, the firm launched a 6.25MWh AC BESS product with string inverters and its ICCS technology for fire safety. The tech is designed for monitoring and protection of battery cells, to prevent thermal runaway and ensure safe operation of the system. It provides early warnings, predictions and an immediate response to potential cell malfunctions.

Before the AC launch, its grid-scale products were DC products. “Amongst the 12GWh of deployments, that has mainly been DC products, especially the 5MWh unit. Now we are shipping the all-in-one AC solution,” Shi said, adding that all regions are showing demand for both DC and AC products.

He added that the PotisEdge brand would remain for the foreseeable future, as it had over a decade of experience in the BESS industry with 12GWh deployed. It has mainly been active in the grid-scale segment, with deployments to date primarily in China, but also in North America, Europe and Australia.

Markets

“Europe is an important market for us, we’ve already delivered for a few sites here like Italy,” he said.

It has 31GWh manufacturing capacity from its facility in Suzhou, China, and a 4-6GWh one in Atlanta, Georgia, US, set to start manufacturing next year. The Atlanta facility will produce the same products as its Suzhou facility, but will be more automated, with only 100 employees needed, Shi said.

“For the US market, the main thing is to localise production, and we’ve focused on solving this for the last two years. All companies are facing that same challenge.”

PotisEdge is also working on a modular BESS solution, as many other system integrators and BESS manufacturers have done in response to transportation issues with ever more energy-dense and heavy 20-foot containers.

As part of its expansion into storage with PotisEdge, Longi will establish a Solar-Storage Technology Innovation Center Center of Excellence in Europe, it said.

Chinese solar PV companies have steadily moved into energy storage, seeking to capitalise on its growth opportunities but also to offset falling profits in their core market as the sector suffers from over-supply. See all coverage of Longi by our sister site PV Tech here.

Germany BESS ‘firsts’: Integrated software, multi-party optimisation, privileged permitting

A week of claimed first-of-their-kind advances in Germany’s BESS market, including the combination of monitoring, diagnostics and energy trading on one platform, an optimisation deal allowing multiple companies to trade one asset virtually, and a law change accelerating permitting.

In summary:

· Investor Dynamic is deploying a BESS where digital monitoring, battery analytics and diagnostics, and energy trading are combined into one single, coordinated system: an industry-first according to the analytics provider Volytica

· Optimisation platform Terralayr has enabled three optimisers – Entrix, Suena and The Mobility House – to virtually trade portions of one single BESS asset

· The German Federal Parliament (Bundestag) has passed a law simplifying the development of energy storage projects, and expressly granting them privileged status

Dynamic’s Tangermünde project’s ‘first-of-its-kind’ integration

Investor Dynamic has partnered with digital monitoring and asset management solutions firm Amperecloud, battery analytics and diagnostics provider Volytica and optimiser Enspired for a 15.8MW/32MWh battery energy storage system (BESS) in Tangermünde, Saxony-Anhalt.

Volytica said it is the first project to “…combine monitoring, battery diagnostics, and energy trading into a single, coordinated system. These features are integrated to simplify operations and ensure competitiveness in today’s energy market”.

The analytics provider said the initiative addresses the common BESS industry challenge of fragmented digital tools for operational control, battery condition monitoring, and commercial optimisation. By integrating their platforms, the partners aim to enable continuous, data-driven system management, from performance monitoring to market participation, it said.

A spokesperson for Volytica said that, normally, you have individual software tools for asset management to operate and maintain the BESS, one tool for trading, one tool to access BMS data and one tool for analytics and monitoring, with no connection between providers.

Volytica CEO Claudius Jehle posted in more detail on his LinkedIn about the concept when Volytica announced the project.

The spokesperson said the integrated approach saves time and money, improves efficiency and competitiveness, and erases blind spots and increase transparency.

The project appears to already be operational, with a photo provided showing BESS units from Trina Storage, though the release did not refer to this.

Terralayr’s multi-optimiser BESS arrangement

BESS optimisation and virtual aggregation platform Terralayr has also claimed an industry-first, software-related asset management breakthrough.

It said its latest commercialisation model creates the “world’s first, risk-adjusted portfolio-effect for storage operators”.

The firm’s virtualisation set up allows multiple optimisers to trade a slice of one or multiple physical assets. The solution is live on Terralayr’s assets, will be rolled out to all future ones as well and available to asset owners in Germany.

Every asset owner has one contract per physical asset and that asset would be disaggregated into virtual batteries. Each virtual battery is then optimised by one different optimiser. As a result, one physical asset is optimised by multiple optimisers in parallel, a spokesperson explained.

A hypothetical arranagement is visualised in the infographic the firm provided below, with the BESS sliced into three virtual assets, 50MW each for Entrix and Suena and 100MW for The Mobility House (for example).

The model is called ‘Enhanced Trading of Flexibility – ETF’, and Terralayr claimed that it drives market efficiency, lowers revenue volatility, and creates a more stable risk-return profile for operators.

It also described an additional benefit called the “netting-off effects”, which regularly occurs when optimisers’ dispatch schedules offset each other, saving battery cycles and reducing degradation.

Terralayr’s platform bundles all optimiser dispatch and ancillary service signals and allocates them to the physical asset, while guaranteeing adherence to all technical restrictions and manufacturer specifications.

The firm launched in 2022, and has onboarded big-name energy firms in Germany including RWE and Vattenfall to its virtual BESS aggregation and optimisation platform as offtakers. Terralayr is deploying its own, smaller grid-scale BESS projects, at least partially to provide capacity for, and prove out, its platform.

Parliament in Germany adopts faster permitting for storage

In related BESS industry news, the German Federal Parliament (Bundestag) passed an amendment to the Energy Industry Act and the Federal Building Code which significantly simplifies the development of energy storage projects, law firm Evershed Sutherlands said in a note.

In a nutshell, the reform elevates legal certainty regarding the privileged treatment of thermal storage facilities, hydrogen storage facilities, and large-scale BESS in outside areas (Außenbereich), the firm explained: such projects are now expressly granted privileged status. The reform aims to accelerate energy storage permitting and deployment.

It creates a major simplification of future permit procedures, whereas previously energy storage was subject to considerable legal uncertainty.

Most grid-scale development in Germany is currently focused around projects that will come online before August 2028, when a three-year exemption from grid fees for charging and discharging ends. The government is discussing a more long-term solution, but whether this new change will benefit projects that can be deployed within the next three years is unclear.

NVIDIA's 800V Architecture Reshapes AI Data Centers: 31 Core Industry Chain Companies Unveiled

CNESA Admin

Industry Analysis

Source: CNESA

“How big is AI's appetite? The power consumption of a large AI data center is comparable to that of a small-to-medium-sized city. More challenging is its power usage pattern, which is like a ‘roller coaster’: one moment it computes at full capacity, and power spikes to its peak; the next moment it exchanges data, and power consumption drops sharply.” Such drastic fluctuations overwhelm traditional power grids and backup power sources represented by UPS (Uninterruptible Power Supply).

Against this backdrop, NVIDIA's recently released 800V DC architecture white paper has significance beyond a simple technical upgrade. It explicitly proposes a key requirement for future AI data centers: the integration of advanced energy storage systems capable of fast response, instantaneous charge/discharge, and intelligent scheduling. This forward-looking guidance signals that the energy storage industry is poised for an AI-driven explosive growth opportunity.

The Energy Bottleneck of Computing Power and Architectural

Breakthroughs

To address this challenge, industry leaders led by NVIDIA have laid out a clear vision, outlining a “three-step” evolution roadmap for the entire sector, aiming to steadily move toward the ultimate 800V DC architecture.

The first step is a transitional solution, innovatively adopting a “side-mounted power cabinet” to physically separate power modules from the core computing area.

The second step, the mid-term solution, promotes the architecture from “distributed” toward “centralized.”

The third step, the ultimate solution, uses SST to achieve a “one-step” conversion from the grid's 10kV medium-voltage AC to 800V DC.

To enable this new architecture to effectively handle power fluctuations, “hybrid energy storage” becomes an inevitable technical core. By organically combining supercapacitors (responding to millisecond-level surges), high-rate batteries (addressing second-to-minute demands), and large-scale energy storage systems, it forms a multi-layered, fast-response backup power system.

However, the new architecture also raises the technical threshold comprehensively.

Traditional silicon-based power chips, like inefficient old engines, can no longer meet the stringent requirements of 800V high voltage. Consequently, third-generation semiconductors represented by silicon carbide (SiC) and gallium nitride (GaN) have emerged.

In this new architecture, SiC acts as the “strongman,” stabilizing high-voltage conversion of tens of thousands of volts in components such as solid-state transformers (SST), while GaN, like a “sprinter,” delivers precise low-voltage power to GPUs inside servers at extremely high speed. They are not just a performance upgrade but the cornerstone enabling the entire new architecture.

The ultimate form of this technological revolution is embodied in the disruptive product, the solid-state transformer (SST). It uses a “high-speed direct route” approach to efficiently convert medium-voltage grid power directly into 800V DC required by data centers, eliminating energy losses from multiple intermediate conversions, saving tens of millions of kWh annually for a large data center.

Under light load, SST efficiency is 5% higher than traditional transformers

Meanwhile, SST replaces heavy copper coils with advanced chips, achieving “silicon in, copper out,” reducing the power supply system footprint by more than half and freeing valuable space for core computing equipment. More importantly, it functions as an intelligent “energy router,” seamlessly integrating photovoltaics, energy storage, and other new energy sources, becoming an indispensable intelligent core for building future AI factories.

Technological and product transformation will ultimately lead to a reshaping of business models. Future competition will no longer be a battle of hardware parameters but a contest of “intelligence,” with suppliers required to evolve into solution providers “understanding computing power.”

This means energy systems must have predictive capabilities, anticipating computing load changes and proactively scheduling resources; simultaneously, they must coordinate intelligently, directing supercapacitors, batteries, and other energy storage units to work efficiently together.

In this transformation, true value is shifting from hardware itself to the control algorithms and software behind it. Future winners will no longer be mere equipment manufacturers but service providers capable of delivering integrated hardware-software intelligent energy solutions.

On November 17, against the backdrop of the majestic Yarlha Shampo Snow Mountain, the China Huadian Corporation’s Wind Power Project in Qonggyai County - whose highest turbine installation point sits at an altitude of 5,370 meters - was officially connected to the grid. The project is not only the largest single-unit-capacity wind power project in the Tibet Autonomous Region, but also the world's highest-altitude operating wind power project, injecting new momentum into green and low-carbon development on the Tibetan Plateau.

Located in Zhongdui Village, Qonggyai County, Shannan City, the Huadian Qonggyai Wind Power Project has a total installed capacity of 60 MW. It is equipped with eleven 5.0 MW turbines and one 6.25 MW turbine, along with a supporting 12 MW/48 MWh grid-forming energy storage system. Once in operation, the project is expected to supply clean electricity sufficient for about 120,000 households annually, equivalent to reducing carbon dioxide emissions by 128,700 tons per year.

Constructing a wind farm at an altitude of 5,370 meters requires overcoming conventional engineering limitations. Facing extreme conditions - oxygen levels at only 57% of those in lowland areas, day-night temperature variation exceeding 20°C, and cumulative road elevation gain of 1,670 meters - the project team tackled challenges with innovative practices:

they planned logistics routes in advance, optimized the allocation of equipment and personnel, and ensured efficient material transportation; they improved concrete mix designs and pioneered a “film + quilt + tarpaulin” layered insulation method, combined with an intelligent temperature-control curing system, to ensure concrete strength and durability in low-temperature environments. These solutions enabled continuous one-time pouring of large-volume concrete under high-altitude, low-oxygen conditions, providing replicable technical experience for ultra-high-altitude wind power construction worldwide. The team also innovated construction methods by applying single-blade hoisting technology for the first time ever at altitudes above 5,000 meters - saving about 66% of the working area compared with traditional whole-rotor hoisting and increasing the upper limit of operable wind speed to 10 m/s - laying a solid foundation for the project's high-quality commissioning.

Throughout construction, the company fully upheld the principles of being “system-friendly, eco-friendly, and community-friendly.” The project incorporates a “equipment selection + energy storage + intelligent control” technical system with a grid-forming storage facility to effectively smooth wind power fluctuations and enhance grid reliability. It strictly followed the four-step method of “lifting, preserving, nurturing, restoring” for high-altitude meadow protection and adopted high-performance substrate ecological spraying technology, restoring a total of 360,000 square meters of vegetation and installing 120,000 square meters of protective mesh, ensuring coordinated progress between engineering development and ecological conservation.

Meanwhile, through land leasing, local employment, construction participation, and skills training, the project directly increased local residents' income by more than 3.6 million yuan and boosted local industries by over 11 million yuan, ensuring that the benefits of clean energy development are shared by people of all ethnic groups in the region.
