DOE now requires energy storage for large-scale renewable energy projects

To improve national grid stability, the Department of Energy (DOE) has issued a new directive requiring all large-scale renewable energy projects to integrate energy storage systems (ESS).

Under Department Circular No. DC2026-02-0008, issued Thursday, all prospective variable renewable energy (VRE) power plants with a capacity of 10 megawatts (MW) or higher must now include energy storage. The storage component must represent at least 20% of the plant’s total installed capacity.

The policy marks a significant shift in how the Philippines manages the inherent intermittency of solar and wind power. By mandating “batteries” or other storage technologies, the DOE aims to mitigate sudden generation losses and ensure a more dependable electricity supply.

“Energy storage is not only about storing surplus energy, it is about strengthening the grid’s capability to absorb more renewables while maintaining reliability,” said Energy Secretary Sharon S. Garin. “This policy ensures that ESS integration becomes part of system planning and project development, supporting better outcomes for consumers”.

The circular also encourages developers to use advanced technologies, such as grid-forming (GFM) inverters. These tools provide “virtual inertia,” helping to stabilize the grid’s voltage and frequency during fluctuations—functions traditionally provided by fossil fuel-based plants.

Beyond private power plants, the DOE has instructed the Transmission Network Provider (TNP) and distribution utilities to incorporate energy storage into their long-term infrastructure strategies. This includes treating storage as a critical resource for grid reinforcement, frequency control, and as an alternative supply for “islanding” scenarios where areas are temporarily cut off from the main grid.

The government plans to institutionalize these requirements by reflecting them in upcoming updates to the Philippine Energy Plan (PEP) and the Transmission Development Plan (TDP). According to the DOE, the updated framework is intended to create stronger signals for investors while accelerating the country’s clean energy targets. (JLN/PIA-NCR)

Jinko ESS SunTera 5MWh Passes Stringent Large-Scale Fire Test, Validating Safety Boundaries

Jinko ESS, a global leading energy storage solution provider and a subsidiary of Jinko Solar Co., Ltd., recently announced the successful completion of a large-scale fire test for SunTera 5MWh Liquid-Cooling Energy Storage System. Conducted at a specialized testing facility in Suzhou City, Anhui Province, the test followed the CSA C800 standard and the November 2025 draft of UL 9540A and was witnessed on-site by CSA Group representatives and North American fire protection engineers.

By simulating fire scenarios under real-world utility-scale deployment conditions, the evaluation assessed fire behavior, thermal runaway propagation potential, enclosure integrity, and the impact on adjacent units. These results provide measured data under the Large-Scale Fire Testing (LSFT) framework referenced in the forthcoming NFPA 855:2026 provisions, supporting the industry’s transition from compliance-driven safety toward performance-validated safety.

Engineering Performance Under Conservative Conditions

The SunTera 5MWh system is Jinko ESS’s flagship product, built on a high-capacity 314Ah cell platform. The system features advanced liquid-cooling thermal management, a nominal energy capacity of 5.015MWh, and supports 0.5P continuous charge and discharge. With an IP55 protection rating and C4/C5 corrosion resistance, it is designed for a 20-year operational life.

For this evaluation, four SunTera containers were deployed in a high-density configuration to replicate practical project spacing:

l Unit A (Initiating Unit): Target unit for forced ignition.

l Unit B: Back-to-back with Unit A at a 15cm spacing.

l Unit C: Side-by-side with Unit A at a 1m spacing.

l Unit D: Face-to-face with Unit A at a 3.5m spacing.

To evaluate passive protection performance under conservative conditions, all units were charged to 100% State of Charge (SOC), active fire suppression systems were disabled, and no manual intervention occurred during the test.

Measured Results: Effective Propagation Containment

On February 10, 2026, forced heating of Unit A commenced at 17:00. At approximately 18:10, cells reached ignition conditions, resulting in sustained combustion. During the event, the internal temperature of Unit A peaked at 1296°C.

Despite the intensity of the initiating fire, adjacent units remained stable. Maximum recorded internal cell temperatures were significantly below thermal runaway thresholds (Unit B: 51.3°C, Unit C: 38.3°C, Unit D: 41.2°C)。

Although external surface temperatures of adjacent enclosures reached elevated levels—up to 404°C on Unit D due to direct flame exposure—internal battery module temperatures remained within safe limits. This demonstrates effective enclosure-level thermal insulation and fire containment performance.

The fire self-extinguished at 07:50 on February 11, with a total combustion duration of approximately 13 hours and 40 minutes. Post-test inspections confirmed:

l Structural Integrity: Unit A maintained its structure with localized surface soot and no enclosure collapse. Units B, C, and D remained structurally intact.

l Functional Continuity: Functional testing verified that adjacent units (B, C, and D) retained full electrical functionality, with no observable impact on charge and discharge performance.

l Environmental Responsibility: The test incorporated controlled flue gas capture and treatment measures to minimize environmental impact.

Leadership Perspectives

“Large-scale fire test allows us to better quantify fire propagation limits,” said Carl Yang, Product General Manager of Jinko ESS. “The SunTera 5MWh system demonstrated thermal runaway containment within a single enclosure under challenging conditions. These data support more precise installation spacing guidance and contribute to reducing multi-unit propagation risk.”

Dora Zhao, Senior Product Management Engineer, said: “SunTera’s safety architecture is built on a three-level design philosophy: cell-level stability, pack-level insulation with engineered pressure relief, and system-level fire barriers. Even when insulation materials in the initiating pack were intentionally modified to accelerate ignition, adjacent packs maintained electrical functionality.”

Patrick Rimel, North America Product Manager, highlighted the market implications: “As regulatory frameworks evolve toward risk quantification, empirical data from LSFT becomes essential. These results provide AHJs, insurers, and project owners with performance-based insights that can inform permitting decisions and risk evaluations, especially in high-density deployments.”

Independent Expert Validation

Todd LaBerge, Fire Protection Engineer from ATAR FIRE, commented: “The test was conducted in accordance with CSA C800 and the latest UL 9540A draft. The system incorporates deflagration protection principles aligned with NFPA 68 and NFPA 69. With enclosure doors closed and venting mechanisms engaged, the initiating fire remained contained within the originating enclosure. The test execution and data integrity meet internationally recognized best-practice standards.”

The Significance Beyond Validation

The impact of large-scale fire testing extends far beyond mere technical validation. It serves as a mirror, reflecting the true safety boundaries of product design, and a yardstick, measuring a company’s fundamental commitment to risk responsibility.

For Jinko ESS, this test marks a new beginning. We remain committed to transforming "extreme conditions" into "standard configurations," working alongside global partners to build a more resilient power system grounded in data-driven trust and safety-first principles.

2. Northwest China Accounted for Over 35% of New Capacity, with Xinjiang Leading

In January, the Northwest region ranked first nationwide, accounting for 35% of newly added capacity. Combined, the Northwest and North China regions contributed more than half of the national total. By province, Xinjiang recorded newly added capacity of 1.2 GW / 4.3 GWh, ranking first nationwide in both power and energy capacity.

By the end of January, Xinjiang’s installed renewable energy capacity exceeded 160 GW, accounting for 64% of the region’s total power capacity. Due to its distance from eastern and central load centers, Xinjiang has historically faced wind and solar curtailment challenges. In 2025, wind and solar utilization rates in Xinjiang were 91.0% and 86.3%, respectively—both below the national average. Growing pressure for renewable energy consumption and the need to mitigate grid fluctuations have driven large-scale deployment of new-type energy storage in the region. At the start of the year, several major projects were commissioned in quick succession, including the 500 MW / 2,000 MWh Ruoqiang energy storage project by Xinjiang Green Development Power, the 200 MW / 800 MWh grid-forming energy storage project by Huaneng Jingshun, and the 200 MW / 800 MWh energy storage project by LiXin Energy, demonstrating strong pilot and demonstration effects.

In terms of revenue mechanisms, Xinjiang has formed a relatively mature model combining capacity compensation, electricity energy trading, and ancillary services. On May 19, 2023, the Xinjiang Development and Reform Commission issued the Notice on Establishing and Improving Supporting Policies for the Healthy and Orderly Development of New-Type Energy Storage, introducing capacity compensation for grid-connected independent energy storage projectsand specified the implementation standards for 2023, 2024, and 2025, providing predictable early-stage policy support for independent energy storage projects in Xinjiang. . Although the original policy expired at the end of 2025, the clarification at the national level regarding capacity pricing mechanisms for grid-side independent energy storage is expected to lead to new local policies in Xinjiang, further improving long-term revenue certainty. With the rollout of ancillary service market rules in July 2025 and the transition of Xinjiang’s power spot market to continuous settlement trial operation, independent energy storage is expected to increasingly generate revenue through spot market arbitrage.

Moreover, Xinjiang has established a complete energy storage industry chain, covering batteries, PCS, BMS, and system integration. Large-scale manufacturing bases established by leading energy storage companies, together with local supply chains, have significantly reduced logistics and system integration costs, enhancing project economics. As grid upgrades and transmission channel construction progress, energy storage demand in Xinjiang is expected to be further released.

The equipment underwent rigorous transportation testing, including over 3,000 kilometers of highway transport and 450 kilometers of reinforced standard-condition road testing. These trials fully validated the system’s ability to withstand complex overland transportation challenges, ensuring structural integrity and stable performance throughout delivery and meeting the stringent requirements of real-world engineering logistics.

One notable highlight of the projects is the application of HyperStrong’s flagship large-capacity liquid-cooled energy storage system, representing the latest advancements in electrochemical energy storage technology. HyperStrong’s independently developed second-generation power conversion system (PCS) features advanced technology with fully independent and controllable core technologies. It can accurately respond to grid dispatch requirements and, through customized design, adapts effectively to complex operating conditions to ensure safe and stable year-round operation. This PCS has been successfully integrated into Beijing KeRui’s integrated unit solution.

Another key highlight is the adoption of CATL’s advanced 587 Ah energy storage cells, which achieve an energy density of 434 Wh/L, a cycle efficiency of up to 96.5%, and further optimized cycle life and degradation performance. This marks the first time Beijing KeRui’s integrated power conversion and step-up system has been deployed in combination with this cell model, demonstrating the company’s rapid response capability in adopting cutting-edge technologies and integrating high-performance components. Beijing KeRui’s integrated design deeply combines core modules—including the power conversion system, step-up transformer, power distribution switchgear, intelligent control, fire protection and security, and thermal management—into a single solution. Through optimized structural topology and layered spatial design, the capacity of a single box-type dry transformer can be increased to over 8,250 kVA, unlocking substantial energy output within limited space. This approach reduces land-use costs while enabling flexible deployment across diverse application scenarios.

The commissioning of the two energy storage power stations will significantly enhance the Inner Mongolia power grid’s ability to accommodate variable renewable energy sources such as wind and photovoltaic power. The projects will effectively smooth peak–valley load differences, improve grid flexibility, and strengthen overall system security and stability. Looking ahead, leveraging the comprehensive advantages of its integrated energy storage power conversion and step-up units—spanning energy efficiency, structural optimization, reliability, and adaptability—Beijing KeRui will continue to provide high-performance, high-reliability energy storage system solutions. The company aims to help customers achieve lower operating costs, higher full life-cycle discharge returns, and improved investment performance.

12.8 GWh Energy Storage Cluster Connected to the Grid AI-Powered Energy Storage Reshapes the Future of New Power Systems

Recently, the world’s largest single-site electrochemical energy storage power station—the Envision Jingyi Chagan Hada Energy Storage Power Station—was successfully connected to the grid. With a total capacity of 4 GWh, the project is fully equipped with Envision’s AI-powered energy storage system. This milestone marks the completion and grid connection of Envision’s 12.8 GWh energy storage cluster deployed across Bayannur, Ordos, Hohhot, Ulanqab, Xilingol League, and Alxa League. To date, Envision-led energy storage projects in Inner Mongolia exceed 14 GWh in total capacity.

The project passed grid verification at rated power through “three charge and three discharge” and a 72-hour continuous trial operation at one time, becoming the largest energy storage project in China to complete such testing. This achievement not only sets new global records for energy storage cluster scale and grid-connection speed, but also demonstrates Envision’s capabilities in ultra-large-scale system integration, extreme-environment adaptability, deep grid interaction, and large-scale project delivery.

Notably, the project’s grid connection coincided with the release of China’s Guidelines on Promoting High-Quality Power Grid Development by the National Development and Reform Commission (NDRC) and the National Energy Administration (NEA), highlighting strong alignment between national policy direction and industrial practice. Together, they signal that AI-centered energy storage technologies are reshaping the future of new power system from technological, market, and application perspectives.

Technology: From “Optional” to “Essential”

The Guidelines clearly state that power system regulation capabilities should be upgraded toward greater diversity and massive-scale coordination. They call for accelerated development of regulation capabilities for new grid-connected entities, including distributed renewable energy and new-type energy storage, to enable the coordinated and optimized dispatch of diverse and large-scale resources. The Guidelines also emphasize strengthening R&D in critical power grid technologies, targeting application scenarios such as deserts, Gobi and barren regions, integrated wind–solar–hydro systems, high-altitude areas, and deep and far-offshore environments. They propose piloting long-distance transmission from large-scale 100% renewable energy bases, and accelerating the engineering validation and deployment of grid-forming technologies.

It is said that Envision’s AI energy storage system deployed in Inner Mongolia integrates advanced capabilities from “grid-following” to “grid-forming”, enabled by a full-time-scale simulation platform and a three-layer grid-forming architecture spanning equipment, system, and site levels. This allows GW-scale stations to connect to the grid immediately upon energization, significantly reducing commissioning time, mitigating oscillation risks, and enhancing system support strength. As a result, energy storage evolves from a “grid follower” to a “grid builder,” providing a solid technical foundation for power systems with high shares of renewable energy.

Market: From Grid Connection to Market Participation

The Guidelines emphasize deep integration between market mechanisms and dispatch systems, and encourage exploration of new pricing mechanisms. This creates clear and predictable revenue pathways for AI-powered energy storage through participation in electricity spot markets, provision of ancillary services such as frequency and peak regulation, and access to capacity compensation and price arbitrage.

The 12.8 GWh energy storage cluster will be fully integrated into the electricity spot market. Leveraging Envision’s AI system—where trading agents and grid-forming agents operate in coordination—the project enables a closed-loop lifecycle operation covering forecasting, dispatch, trading, and self-learning. This approach not only enhances the intelligence, efficiency, and execution of power trading decisions, but also provides a replicable and scalable model for the large-scale participation of new-type energy storage in electricity markets. At the same time, it significantly improves regional renewable energy consumption and strengthens the operational resilience of the power grid. In previous deployments, Envision’s AI energy storage system has ranked first in trading forecast accuracy at several sites in Inner Mongolia for consecutive months. Based on measured operational data, the project is expected to increase total lifecycle returns by more than 20%.

Applications: From Single Use to Broad Scenarios

The Guidelines elevate smart microgrids as a key component of new-type power systems, unlocking vast opportunities for AI energy storage in industrial parks, zero-carbon parks, and remote areas. In these scenarios, AI-powered energy storage functions as a local energy brain, optimizing the coordination of generation, grid, load, and storage to maximize renewable self-consumption, enhance supply reliability, and enable higher-level grid interaction.

As power systems become increasingly clean and market-oriented, simple equipment aggregation is no longer sufficient. In high-renewable scenarios, AI-driven energy storage that balances grid stability with revenue optimization has become indispensable. The successful grid connection of the Inner Mongolia cluster underscores Envision’s leadership in physical AI and AI-enabled renewable energy solutions.

Envision has established a full industrial chain in Inner Mongolia, from battery cells and system integration to project delivery and intelligent operation. Leveraging its integrated capabilities, the project drives industrial clustering, injects new momentum into the local economy, supports the development of a new-type power system, and underpins the region’s efforts to accelerate the construction of a nationally important energy and strategic resources base.

This milestone delivery marks a successful conclusion to Envision’s energy storage business expansion in 2025. Empowered by physical artificial intelligence, Envision has secured a series of major contracts both at home and abroad this year. Building on its established global footprint, the company has successfully expanded into ten strategic overseas markets, including Australia, Chile, Italy, and Poland. Looking ahead, Envision will continue to strengthen the foundational support for next-generation power systems through innovative products and world-class project execution, accelerating the global transition toward zero-carbon and driving a new era of shared prosperity powered by Chinese renewable energy technologies.

Faster Deployment by Local Energy Groups Highlights Investor Diversification

Driven by rising market demand, supportive national policies, diversified technology pathways, and declining costs, the market potential of energy storage is being fully released, with increasing investor diversification.

In November, projects invested in and built by local energy groups such as Xinjiang Energy Group, Xinjiang Zhongyuan Power Group, and Shenergy Group were commissioned in succession. Local energy groups accounted for 45% of newly added power capacity - the highest among all enterprise types - contrasting sharply with September and October, when third-party enterprises and the “Five Major and Six Minor” power generation groups dominated.

Leveraging advantages in policy coordination and approvals, resource integration and location, business linkage and industrial chain synergy, capital strength and decision-making efficiency, and operations, local energy groups have become a key pillar of the new-type energy storage market. Meanwhile, third-party enterprises - such as joint entities involving Conch New Energy and CATL, and Inner Mongolia Zhongdian Energy Storage - maintained a high level of participation, accounting for over 30% of monthly additions. The “Five Major and Six Minor” power generation groups (including China Huaneng, SPIC, and China Huadian) accounted for 22%, down 9 percentage points from October, continuing the decline seen since August.

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

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.

Puerto Rico Advances on Its Delayed Accelerated BESS Deployment Programme

Source: Energy Storage News

---

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.”

200MW/800MWh! China's Largest Semi-Solid-State Energy Storage Project Connected to the Grid

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.

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

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.”

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

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.

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.
