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.

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.

4GW/5.12GWh Malaysia Solar-Plus-Storage Hub Receives World Bank Funding

Source: PV Tech

The agreement was signed this week, in the presence of the Queen of Malaysia (pictured). Image: IFC

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.

World's Highest-Altitude Operating Wind Power Project Now Connected to the Grid

Source: China Electric Power News

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.

The Victoria government in Australia has approved a 300MW/1,200MWh battery energy storage system (BESS) in Gippsland and a 332MW solar PV power plant with integrated storage in the state’s northeast region, via the Development Facilitation Program.

Victoria’s planning minister, Sonya Kilkenny, announced the approvals for Eku Energy’s Tramway Road standalone BESS and the Meadow Creek Solar Farm, which combines a 332MW solar PV plant with a 250MW/1,000MWh battery system.

The projects represent approximately AU$1.2 billion (US$780 million) in combined investment and will create over 650 construction jobs across both developments.

Eku Energy’s 1,200MWh Tramway Road BESS

The Tramway Road BESS will deliver a 4-hour duration storage capacity of 300MW, positioning the facility to provide grid stability services and energy arbitrage opportunities across Victoria’s transmission network.

Located in Hazelwood North, the project will be constructed adjacent to existing transmission infrastructure where developer Eku Energy already operates the 150MW/150MWh Hazelwood BESS at the former Hazelwood Power Station coal-fired power plant.

Eku Energy has numerous projects under development in Australia, while also maintaining a presence in several other international markets. The company, which is jointly owned by Macquarie Asset Management and British Columbia Investment Management Corporation, aims to achieve 9GWh of storage capacity by 2028 and has recently expanded into the New Zealand market.

The Tramway Road facility will connect directly to the transmission network, enabling participation in the National Electricity Market (NEM) ancillary services while supporting the integration of renewable energy across southeastern Australia.

The 1,000MWh Meadow Creek solar-plus-storage site

Meanwhile, the Meadow Creek Solar Farm, located 27km southeast of Wangaratta, is being pursued by energy storage developer and system integrator Energy Vault.

Alongside the solar PV power plant, the project proposal includes a co-located 250MW/1,000MW battery system that would provide additional grid stability services during peak demand periods.

The hybrid project will span 400 hectares of agricultural land and incorporate agrivoltaics principles, allowing continued farming operations beneath and around the solar installation.

The Meadow Creek development was first announced in 2022’s edition of All-Energy Australia, where the developer described the BESS as a 250MW/500MWh system.

The Victoria government’s Development Facilitation Program initiative, which was expanded last year to include renewable energy projects, aims to speed up the development of critical infrastructure projects in Victoria.

Before its inclusion, projects had to pass through the Victorian Civil and Administrative Tribunal, which resulted in around 20% of these projects being delayed by approximately two years.

The Victoria government noted that more than AU$7.8 billion worth of investment across 22 projects has been included in the Development Facilitation Program since it was expanded to include renewables.

Victoria’s energy and resources minister, Lily D’Ambrosio, emphasised the projects’ role in delivering lower energy costs to Victorian households while creating employment opportunities in regional communities.

“Our fast-tracked pathway has unlocked nearly AU$8 billion worth of investment into renewable energy projects – helping provide cheaper and cleaner energy to hundreds of thousands of Victorian households,” D’Ambrosio said.

Other notable BESS projects to have advanced through the initiative in recent months include Chinese PV module manufacturer Trina Solar’s 500MW/1,000MWh Kiewa Valley BESS, which is being developed in the Murray-Darling basin, to the east of Melbourne, the state capital. 

Developer ACEnergy also saw its 350MW/770MWh Little River BESS included within the scheme earlier this year.

Power firm RWE has launched construction on a 400MW/700MWh BESS project in Bavaria, Germany, the largest being built in the country.

The Germany-headquartered firm announced the start of construction on the project yesterday (29 October), in a ceremony attended by Bavarian Minister-President Dr Markus Söder (pictured above, second from left).

The 1.75-hour duration battery energy storage system (BESS) project is being built alongside the Gundremmingen nuclear power plant, which is undergoing decommissioning, and will use the plant’s existing grid connection.

RWE is investing around €230 million (US$267 million) in the BESS, which will comprise 200 container units and 100 inverters, and is expected online in 2028. It will take the title of largest BESS online from Eco Stor’s 103.5MW/238MWh Bollingstedt, commissioned earlier this year, as well as Eco Stor’s pipeline of 300MW/600MWh projects.

Söder commented: “Gundremmingen remains a key location in the Bavarian energy supply. In addition to the new battery storage facility, a 55-hectare solar park and a gas-fired power station are also set to be built. With an output of 400 MWand a capacity of over 700MWh, the battery storage facility will stabilise the grid when there is no wind or sunlight.”

Germany has emerged in the past few years as one of Europe’s most attractive markets for large-scale BESS investment, with large opportunities in its wholesale energy market (Europe’s deepest) and helpful regulatory changes including an exemption from charge-discharge grid fees for BESS projects put into operation by 2029.

Those opportunities are set to grow as the country deploys more wind and solar, and solar trade body BSW-Solar recently called for 100GWh of BESS deployments by 2030.

We recently caught up with German BESS platform Terra One to discuss the market drivers, regulatory challenges and the trade-offs when opting for a merchant or toll-based strategy in the country.

CRRC Zhuzhou Institute Helps the Nationwide Largest User-Side Grid-Forming Energy Storage Connect to the Grid!

Source: CRRC Zhuzhou Institute

Recently, the “Wind-PV-Storage” Green Low-Carbon Energy Supply Project of Jingjiang Special Steel Co., Ltd., a National Low-Carbon Metallurgy Technology Research Pilot Project invested by Xinli Era under the CITIC Pacific Energy Co., Ltd., was successfully connected to the grid.

 

As the general contractor for the 120 MW / 240 MWh grid-forming high-voltage direct-connected energy storage system, CRRC Zhuzhou Institute Co., Ltd. applied high-speed rail-grade grid-forming converter technology and system integration expertise to successfully help Jingjiang Special Steel Co., Ltd. create China’s first near-zero-carbon steelmaking demonstration plant, providing an effective model for intelligent, green, and low-carbon transformation in the steel industry.

The project’s completion marks the beginning of a strong partnership between CITIC Pacific Energy and CRRC Zhuzhou Institute in the industrial and commercial energy storage sector.

To meet the project’s fast grid connection requirements, CRRC Zhuzhou, after confirming the technical specifications, completed the full delivery of the 120 MW / 240 MWh grid-forming high-voltage direct-connected energy storage system within 45 days. Working with China Energy Engineering Group Jiangsu Power Design Institute Co., Ltd., they integrated a 36 MW distributed PV system and a 16.8 MW onshore wind power system to provide a comprehensive energy supply. Through the system’s grid-forming energy storage stability and fast-response capability, the project overcame challenges from high-impact steelmaking loads and the strong intermittency of renewable energy, optimizing energy matching in time and space, improving energy coordination efficiency, reducing carbon emissions, and achieving both high-efficiency stable production and green low-carbon goals.

01 Establish a zero-carbon industrial park

Building a resilient microgrid to ensure stable renewable energy supply

 

Upon completion, it will become China’s first grid-forming wind-PV-storage integrated microgrid demonstration project in the steel industry, expected to provide 75 million kWh of green electricity annually, reducing carbon emissions by 62,400 tons. By coordinating wind, solar, and storage with electric furnace loads, the project offers a full-process energy solution, helping Jingjiang Special Steel build a new green and low-carbon brand.

Focusing on continuous short-process electric furnace production, the project deploys grid-forming energy storage at the park level with three main objectives: stabilize power quality, increase the share of green electricity, and ensure continuous production. The park’s grid is structured to be autonomous, grid-connected, and switchable, transforming green electricity from “uncertain supply” to “stable, controllable, and high-quality supply”.

 

02 Technical Highlights

Power quality and renewable energy utilization have become key

challenges for zero-carbon industrial parks

teelmaking, as a typical high-load and high-impact process, demands high grid stability and reliability. Addressing the intermittency and fluctuations of renewable energy is key to achieving high-proportion green power supply. The mismatch between PV, wind power, and load limits renewable utilization, while the energy storage’s power and energy regulation capabilities effectively solve this problem. Grid-forming energy storage becomes an indispensable part of high-quality, high-utilization renewable microgrids.

 

High-voltage direct-connection architecture: breaking the “shackles” of efficiency and cost

 

The high-voltage direct-connected architecture developed independently by CRRC Zhuzhou uses H-bridge module cascades to synthesize 35 kV on the AC side, eliminating transformers, shortening energy paths, reducing system current and line losses, and enabling system cycle efficiency to exceed 92%, which is 6% higher than conventional low-voltage storage. This also reduces civil and equipment investment, adding about RMB 48 million in revenue over the 240 MWh storage system lifecycle.

 

Grid-forming energy storage: microgrid stabilizer

 

Grid-forming energy storage actively generates stable voltage and frequency, effectively combining “stabilizer + independent power supply”. The system provides 3×10-second grid-forming capability, and under high-impact steelmaking load conditions, its direct connection to the grid allows rapid response within 20 ms, providing instantaneous power support and bus voltage stability, ensuring power quality and production continuity.

 

Performance leap: millisecond-level grid connection/disconnection and 10-second black start

 

High-voltage cascaded direct-connected grid: shorter electrical distances and greater overload capacity. The system’s single-unit capacity reaches up to 45 MW. In the event of an external grid outage, it can achieve millisecond-level smooth grid connection / disconnection within 100 ms, forming an independent and stable high-voltage microgrid. It also features a 10-second rapid black start, requiring no external grid support, allowing the system to autonomously establish a stable high-voltage microgrid and restore power within seconds, ensuring uninterrupted, loss-free operation of high-load steel production lines.

 

Integrated source-grid-load-storage platform, unlocking 100% potential of grid-forming energy storage

 

The integrated source-grid-load-storage platform provides a framework that is observable, measurable, adjustable, and controllable, optimizing charging and discharging strategies based on weather and output forecasts. Local green electricity utilization is increased from below 70% to over 95%, with annual additional green power benefits exceeding RMB 10 million. In abnormal conditions, the platform triggers safety mode for rapid grid-forming switching. Full-state awareness and strategic dispatch of the storage system reduce manual intervention by over 90%, simplifying operations and maintenance.

03 Multiple Benefits and Industry Breakthroughs

Grid-forming energy storage releases multiple values including capacity,

regulation, and power quality

 

The revenue structure is clear: it can increase green power utilization by 168 million kWh annually, reduce downtime and equipment wear, and generate additional benefits through green power trading and certificates, turning electricity from a cost center into an asset operation.

The next step is to integrate the park into virtual power plants for power market participation, releasing value in capacity, regulation, and power quality in a new-type power system that emphasizes system stability.

 

The Jingjiang Special Steel model: grid-forming energy storage empowers high-energy-consumption parks for zero-carbon transformation

 

In the near future, the Jingjiang Special Steel experience will be replicated across more industrial parks to strengthen capabilities in “park autonomy + multi-energy coordination + carbon accounting”. High-energy-consumption parks will be efficiently and reliably served through the “three-piece delivery suite” of standardized hardware combinations, scenario-based control strategies, and park-level dispatch interfaces. With more advanced energy storage system architectures and technologies, power quality and system resilience will be developed into tradable resources. Grid-forming energy storage helps microgrids reduce dependence on the main grid and, through the source–grid–load–storage–carbon coordination, enables dynamic capacity expansion, local autonomy, and high renewable energy utilization, becoming key infrastructure for industrial zero-carbon transformation and power grid modernization.

 

Pioneer of Grid-Forming Energy Storage: CRRC Zhuzhou Institute’s Experience and Vision

 

CRRC Zhuzhou Institute has successfully leveraged its extensive expertise in high-voltage converter design, multi-level converter topology development, and over 20 years of engineering experience with high-voltage conversion equipment in the rail transit sector to the energy storage field. This led to the launch of the grid-forming high-voltage direct-connected energy storage system, achieving seamless technological integration from the “heart of rail transit” to the “backbone of energy storage”.

As of September 2025, CRRC Zhuzhou’s grid-forming energy storage systems have reached a cumulative grid-connected capacity of 3 GWh and a contracted capacity of 5 GWh. Landmark projects such as the world’s first high-altitude grid-forming storage station in Ali, Tibet, and China’s first user-side high-voltage cascaded grid-forming storage station in Jingjiang, Jiangsu, have successfully demonstrated the company’s ability to provide highly reliable grid-forming energy storage solutions in extreme environments and complex industrial scenarios.

Looking ahead, CRRC Zhuzhou Institute will continue to advance innovation and application of grid-forming energy storage technologies, contributing more key technologies to drive the energy transition and industrial zero-carbon development.

Recently, construction of China’s largest user-side energy storage project - the 107.12 MW / 428.48 MWh Guangyuan Zhongfu & Guangyuan Linfeng User-Side Lithium Battery Energy Storage Project in Sichuan Province - has entered its final phase. Since construction began on July 30, 2025, all work has proceeded steadily according to plan, with full efforts now focused on achieving the completion target of November 30.

The project is jointly developed by Great Power, a leading company in the energy storage industry, and Henan Zhongfu High Precision Aluminum Co., Ltd (Zhongfu Aluminum), a top enterprise in the aluminum sector. Located only 210 meters from Zhongfu Aluminum’s plant, the project directly connects to the 10 kV power distribution system, significantly reducing transmission losses and improving energy efficiency. It is linked via cables to two 220 kV substations in the industrial park and operates on a “charging during off-peak, discharging during peak” model, with a maximum charge/discharge power of 107 MW and a total capacity of 428.48 MWh, allowing for 4 hours of full charge and discharge per cycle.

Once operational, the project will not only reduce electricity costs and enhance power reliability for Zhongfu Aluminum, but also help the power grid with peak shaving and load balancing. According to plans, Phase II of the project construction will expand the system to 400 MW / 1,000 MWh, along with the construction of a new 220 kV substation, wind and solar power facilities, and EV charging stations. Ultimately, the project aims to establish an integrated “generation - grid - load - storage - charging” regional microgrid in Guangyuan, Sichuan province, providing a practical model for China’s power market reform and carbon neutrality goals, while injecting green momentum into the city’s economic and social development.

Naturgy launches Construction on First Portion of Ten-site, 160MW BESS Portfolio in Spain

Utility and power firm Naturgy has started building its first BESS projects in Spain, at a ten-site portfolio in Almeria and the Canary Islands.

The company announced groundbreaking on the first four of a ten-site portfolio on 16 October, saying the whole portfolio will total 160MW of power and 342MWh of energy storage capacity, an average duration of 2.13 hours.

The projects will be combined with four solar PV systems. The first battery energy storage systems (BESS) are being added to the Tabernas I and II PV plants in the province of Almería, and the El Escobar and Piletas I in Las Palmas (Canary Islands).

Naturgy plans to have launched construction on all ten by 2026, nine of which are hybridised with PV with one standalone project in Vigo (Pontevedra). It didn’t reveal the size of the four initial projects, which will come online in 2026.

The lithium-ion BESS will reinforce the electricity market in Spain and help to integrate more intermittent renewable energy, and Naturgy is investing €80 million (US$94 million) in them.

The projects are recipients of funding under Spain’s energy storage capex support scheme funded by the EU’s Recovery and Resilience framework, which is funding up to 3.5GWh of projects.

Naturgy’s peer Galp similarly announced the start of construction on BESS projects in Spain (and Portugal) earlier this year, as did Iberdrola in August.

Spain aims to be 81% powered by renewables by 2030, according to the country’s National Energy and Climate Plans (NECP), and energy storage will be key to helping to maintain system reliability and dampen price volatility. The government forecasts that 22.5GW of BESS will be needed by that date.

Spain and Portugal suffered a near country-wide blackout in April this year, which commentators have suggested could have been better mitigated with more grid-supporting and grid-forming technologies, including energy storage.

Naturgy is based in Spain but its first major large-scale activity was in Australia, bringing online the 128MW Cunderdin hybrid solar PV and 55MW/220MWh BESS in Western Australia in early 2025.
