New Installations Surge Over 120% YoY — February Analysis of China’s New Energy Storage Projects

In February 2026, China’s new energy storage market sustained its rapid growth momentum, with newly installed capacity increasing by over 120% year-on-year (YoY). Meanwhile, the application structure of the market has undergone adjustments compared with the same period last year.

Short-term fluctuations do not alter long-term growth trend: In February, newly installed capacity reached 3.6 GW, representing a YoY increase of over 120% and a month-on-month (MoM) decline of 31%. Despite the short-term slowdown, the long-term growth trajectory of the energy storage market remains strong.

Front-of-the-meter standalone storage drives growth: Standalone energy storage on the generation and grid side became the primary growth driver. In February, standalone storage accounted for 90% of newly added capacity, up 42 percentage points YoY. Newly installed power and energy capacity of standalone storage increased by more than 310% and 270% YoY, respectively.

Highly concentrated regional deployment: The Northwest region accounted for over 75% of total additions, with Ningxia alone exceeding 2 GW, contributing more than 60% of the national total.

According to incomplete statistics from China Energy Storage Alliance(CNESA), China commissioned 3.56 GW / 8.19 GWh of new energy storage capacity in February 2026, representing YoY increases of +120% / +95% and MoM declines of -31% / -21%.

The MoM decline was mainly due to project construction cycles and the impact of the Spring Festival holiday. However, the YoY growth exceeding 120% indicates a fundamentally positive market outlook. Notably, front-of-the-meter (FTM) installations reached 3.4 GW, up 147% YoY, effectively doubling the total monthly additions.

Key Market Characteristics in February

1. Standalone Storage Surges Over 270%, Driving Market Expansion

In terms of application structure, standalone energy storage dominated the market. It accounted for 90% of total newly installed power capacity, up 42 percentage points YoY and 8 percentage points MoM. Newly added capacity reached 3.2 GW / 7.4 GWh, with YoY growth of +313% / +274%, becoming the main driving point of energy storage market. All newly commissioned standalone energy storage projects reached at least the 100 MW level, with the number of such projects rising by 29% year-on-year, alongside the commissioning of two gigawatt-scale projects.

Installations on the generation side and behind-the-meter (BTM) user side experienced a temporary decline. Newly installed capacity on the generation side reached 217.3 MW / 474.3 MWh, down 65% / 72% year-on-year and 41% / 36% month-on-month. Co-located storage with renewable energy remained the dominant model, covering a range of application scenarios such as aquaculture, solar hybrid projects and desertification control initiatives.

New user-side installations totaled 135.2 MW / 292.7 MWh, down 41% / 42% year-on-year and 51% / 58% month-on-month. The market was highly concentrated, with Jiangsu, Guangdong, and Zhejiang accounting for 90% of total user-side energy storage capacity, while Jiangsu ranked first nationwide in both installed capacity and project count.

On the technology front, lithium-ion batteries continued to scale rapidly, supporting the commissioning of gigawatt-level standalone storage plants. Meanwhile, hybrid systems combining lithium-ion and sodium-ion batteries at the 100 MW level were deployed, and aqueous organic flow batteries were implemented on the user side, providing more diversified technological pathways for long-term development.

2. Regional Concentration Intensifies, Northwest China Dominates

In February, regional concentration of new installations was pronounced. The Northwest region added 2.7 GW, accounting for 76% of the national total. The combined share of the Northwest and North China regions exceeded 90%. Ningxia added 2.2 GW / 4.4 GWh of new capacity, ranking first nationwide in both power and energy scale and setting a new monthly record for the region. This surge was driven by the grid connection of several gigawatt-scale shared energy storage projects and storage systems paired with large renewable energy bases.

By the end of 2025, Ningxia’s renewable energy capacity reached 57.32 GW, accounting for 65.5% of total grid capacity under centralized dispatch. Solar power has surpassed coal-fired generation to become the largest power source in the region. Due to the intermittency of renewables—characterized by surplus generation during the day and shortages at night—demand for grid services such as peak shaving and frequency regulation has surged. A coordinated development model integrating wind, solar, thermal power, and energy storage is rapidly taking shape. Looking ahead, energy storage is expected to generate revenue through multiple channels, including capacity compensation, spot market trading, frequency regulation services, ramp rate support and so on.

In addition, Ningxia has introduced policies encouraging private capital participation in energy storage investment. In February, a gigawatt-scale storage project developed by Jiayang Energy was commissioned, demonstrating strong investor confidence in the region. At the end of February, the region released its first batch of 2026 private investment promotion projects, including 22 energy storage projects with a total scale of 4.15 GW / 14.4 GWh, providing a solid pipeline for continued market growth.

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.

Sharp Pullback! User-Side Energy Storage Additions in January Down 58% Year-on-Year

In January 2026, China’s user-side new energy storage market recorded a year-on-year decline of more than 50% in newly added capacity. The pace of project filings slowed while quality improved, and market deployment shifted toward larger single projects and more capital-intensive investments.

The user-side energy storage market experienced a clear correction, with installed capacity down 58% year-on-year. Commercial and industrial (C&I) energy storage accounted for more than 90% of total additions.

The East China region contributed over three-quarters of newly commissioned capacity. Jiangsu led the nation, accounting for 60% of total installed capacity.

Nationwide, the number of newly filed user-side projects fell by 38% year-on-year, while the average size of individual projects increased by 87%. Core markets—Jiangsu, Guangdong, and Zhejiang—continued to lead, as user-side deployment shifted from small, distributed projects toward larger-scale, more centralized investments.

Analysis of User-Side New Energy Storage Projects in January

In January, newly commissioned user-side energy storage capacity totaled 166.2 MW / 456.5 MWh, representing -58% / -39% year-on-year and -81% / -73% month-on-month. The following characteristics were observed.

(1) Installed capacity of user-side energy storage 

In January, the market remained dominated by C&I applications, accounting for over 90% of total additions. Newly commissioned C&I projects reached 156.7 MW / 435.4 MWh, down 60% / 41% year-on-year and 82% / 74% month-on-month.

From a technology perspective, all newly commissioned projects adopted electrochemical energy storage. Lithium iron phosphate (LFP) batteries accounted for more than 99% of installed power capacity. In the long-duration energy storage, one 7-hour photovoltaic-plus-storage integrated smart power station project and one 4-hour solid-state lead battery energy storage project were commissioned.

Note: “C&I” includes industrial facilities, industrial parks, and commercial buildings; “Others” include mining areas, oilfields, rail transit, data centers, etc.

(2) Regional Distribution of User-Side Energy Storage

By region, newly commissioned projects were distributed across 13 provinces, including Jiangsu, Anhui, Shandong, Sichuan, and Guangdong. East China dominated the January market, accounting for 78% of newly added capacity and 44% of total project numbers.

At the provincial level, Jiangsu ranked first nationwide, contributing 60% of total installed power capacity and 16% of newly commissioned projects. Both installed capacity and project count ranked first nationally. This performance was driven by a combination of power market reforms, demand response incentives, strong C&I demand, and the centralized grid connection of large-scale projects.

On the policy front, multiple supportive measures were introduced, accelerating the transition of user-side energy storage business models from “fixed arbitrage” to “volatility-driven optimization.” In January, Jiangsu implemented new power market reforms, with the Jiangsu Energy Regulatory Office releasing the Implementation Rules for the Jiangsu Medium- and Long-Term Power Market (Draft for Comments). These rules marked a shift in C&I electricity pricing from fixed time-of-use tariffs to fully market-based pricing. In the short term, this reduced fixed peak–valley arbitrage margins; however, in the medium to long term, more frequent price fluctuations are expected to create diversified arbitrage opportunities for projects with advanced forecasting and intelligent dispatch capabilities. In addition, as of January 1, 2026, Jiangsu officially implemented full market participation for all renewable electricity, making photovoltaic-plus-storage integration a necessity for smoothing output profiles and enhancing market-based revenues. During the critical winter peak demand period, user-side storage projects could also participate in demand response programs, earning peak-shaving compensation of up to RMB 4.8/kWh, significantly improving short-term revenue certainty and incentivizing projects to connect to the grid within the policy window.

On the demand side, structural factors continued to underpin market growth. January marked the winter peak electricity demand season in Jiangsu. On January 20, the province’s maximum load reached 135 GW, a new winter record and the highest nationwide for six consecutive years. Grid balancing and supply security pressures highlighted the system value of user-side storage. As a major manufacturing province with a high concentration of energy-intensive industries, Jiangsu faces strong demand for peak shaving, valley filling, and demand charge optimization. In January, peak–valley price spreads remained above RMB 0.6/kWh, supporting stable combined returns from energy arbitrage and demand management. Moreover, Jiangsu’s large installed base of distributed photovoltaics further amplified demand for storage, as pairing PV with storage under full market participation policies enables off-peak discharge and enhances project economics.

From a market structure perspective, growth in Jiangsu exhibited clear characteristics of scale and concentration. In January, several large projects—such as the 300 MWh user-side energy storage project of Jiangsu Huiran Industrial Co., Ltd.—along with multiple projects exceeding 5 MW / 40 MWh, were commissioned. Large-capacity projects accounted for the majority of additions, reinforcing Jiangsu’s “fewer projects, higher capacity” market profile. In addition, Jiangsu benefits from a well-developed local energy storage industrial chain. Through full-chain coordination, economies of scale, resource sharing, technology reuse, and business model innovation, system-level costs—including initial investment, operations, and lifecycle costs—can be significantly reduced, providing a strong industrial foundation for continued user-side market growth.

(3) Project Filings

From the perspective of project filings, January saw a “less but better” trend nationwide. The user-side market shifted from distributed expansion to scale and centralized development. The number of newly filed user-side projects fell by 38% year-on-year, while total filed capacity increased by 16%, and the average project size of single projects rose by 87%. In traditional markets, Jiangsu, Guangdong, and Zhejiang together added 321 new projects, down 42% year-on-year, while total energy capacity increased by 28%. Jiangsu recorded the largest total filed capacity, while Guangdong led in the number of newly filed projects. Over the past three years, Jiangsu has consistently seen year-on-year growth in both total filed capacity and average project size in January. This January, Jiangsu’s newly filed capacity rose 81% year-on-year, while project numbers declined 44%, resulting in an average project size roughly three times that of the same period last year—highlighting a clear trend toward larger individual projects. By contrast, Zhejiang continued to see declines in newly filed projects. In January, the number of projects fell 67% year-on-year, and total capacity declined 86%.

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.

3. Faster Deployment of Projects Invested by Third-Party Enterprises, the trend toward

diversification of energy storage investment entities has become increasingly evident.

In January, projects invested and developed by third-party enterprises—including China Green Development Group, Aerospace Hongji Energy Storage, and Daowei Energy Storage Group—were commissioned one after another. Third-party enterprises accounted for 45% of newly added installed power capacity, ranking first among all investor categories. Driven by rising market demand, supportive national policies, diversified technology pathways, and declining technology costs, the investment entity diversification trend became more pronounced in the first month of 2026.

Key Energy Storage Standards to Watch in 2026 Highly Recommended for Industry Reference

During the 14th Five-Year Plan period, China’s energy storage technology mix witnessed noticeable changes where pumped hydro storage accounted for less than 40% for the first time while the new-type energy storage represented by lithium batteries saw explosive growth.

According to incomplete statistic from China Energy Storage Alliance (CNESA), by the end of 2025, China’s cumulative installed capacity of power storage reached 213.3GW among which pumped hydro storage shared 31.3% while the new-type cumulative energy installations represented by lithium battery accounted for over two thirds.

Against the backdrop of robust industry expansion, it is significant to improve energy storage standardization system especially enhancing safety standard.

Through the incomplete statistic, in 2025, China released over 40 national, industry and local standards on energy storage. These standards cover energy storage planning and designing, equipment testing, grid connection and operation, safety management and emergency response, providing important support to guide high-quality industry development, guarantee the safety of energy storage power stations, and promote the energy structure transformation and the green and low-carbon development across industrial value chain.

This article aims to clarify major energy storage standards released in 2025 and their influence. It will also list the key standards that have already come into force or will be implemented in 2026, helping industry stakeholder stay aligned with regulatory developments, mitigate compliance risks, and ensure the safe and efficient advancement of projects.

Strengthening the Energy Storage Safety Standards System From “Recommended” to “Mandatory”

Electrochemical Energy Storage represented by lithium battery has developed in a breakneck speed where installed capacity continued to expand, with safety being a core concern for the industry. In accordance with the incomplete statistic, 2025 alone saw about 30 energy storage safety accidents across the world. Two fires happened consecutively in American Moss Landing energy storage plant with huge loss, drawing widespread attention.

In order to ensure the safe and stable operation of lithium battery energy storage systems, cut down accident incidences and improve emergency response capabilities, the mandatory national standard GB 44240 Secondary lithium cells and batteries used in electrical energy storage systems—Safety requirements officially came into effect on August 1, 2025, which is recognized as the highest-level national standard on energy storage safety to date. It upgrades the safety requirements of energy storage lithium battery from “recommended” to “mandatory” for the first time, covering more than 20 rigorous testings from cell vibration, acceleration shock, shallow puncture, and compulsory discharge. Several leading companies’ battery products like those of CATL have passed third-party testings which is a sign that the standard’s entry into substantive implementation, setting a new benchmark for energy storage industry.

China’s Ministry of Housing and Urban-Rural Development released the revised national standard GB/T 51048- 2025 Design Standard for Electrochemical Energy Storage Power Station. Issued on December 31, 2025 and effective on April 1, 2026, this standard represents the first revision in a decade. Through revision across ten years, it introduces new  technology pathways of sodium batteries, hydrogen fuel cells and so on. Based on practical challenges encountered during the application of electrochemical energy storage pathways over the past ten years, it established differentiated design requirements and addressing the potential safety risks serves as a core technical reference for the design of electrochemical energy storage power stations.

Shifting the Focus of Safety Protection from “Post-Incident Response” to “Pre-Incident Prevention”

With the continuous breakthroughs of safety protection technologies, shifting from “post-incident response” to “pre-incidence prevention” gradually become one of the major strategies.

China’s first national electrochemical energy storage fire warning standard GB/T 46261- 2025 General technical requirements for fire monitoring and warning systems for electrochemical energy storage stations was issued on August 29, 2025 and will take effect on September 1, 2026. This standard established a systematic and standardized framework for fire monitoring and early warning systems for the first time, covering several performances and technology requirements like multi-parameter monitoring, coordinated control and environmental adaptability and filling the long-standing gap in standards for early fire monitoring and warning product, which holds important reference for  accident monitoring and safety warning system design in energy storage power stations.

CNESA standard Technical Specification for Liquid Nitrogen Fire Extinguishing Systems in Electrochemical Energy Storage Power Stations is currently under public consultation. Developed based on national key R&D program outcomes, the standard consolidates technical achievements in liquid nitrogen fire suppression systems and their application in protecting lithium-ion battery energy storage systems.

Internationally, the 2026 edition of NFPA 855 has also placed pre-incident prevention at the center of safety management. Systematic risk identification and mitigation analysis have been upgraded from conditional to routine requirements. It firstly introduced large-scale fire testings on the assessment of thermal runaway propagation. CSA/ANSI C800-2025 and the fifth edition of UL 9540A came as follows, which update large-scale fire testings requirements and significantly improve the proactive safety protection requirements of energy storage products.

Initial Progress Energy Storage Footprint Accounting Standards Supporting the “Dual Carbon” Goals

As the GB/T 24067- 2024 Greenhouse gases—Quantification methods and requirements for carbon footprint of product—Lithium-ion battery for electrical energy storage systems releases, China has built the foundational framework of carbon footprint accounting. Subsequently, the Ministry of Ecology and Environment together with National Development and Reform Commission and other authorities jointly issued the ‌Guidelines for Developing Product Carbon Footprint Accounting Standards, encouraging broad participation in the design and amendment of product carbon footprint accounting standards. The guidelines target the formulation of 100 product carbon footprint standards by 2027 and 200 by 2030. Building on this framework, sector-specific carbon footprint standards are now gradually being developed.

In 2025, draft standards such as Greenhouse Gases—Product Carbon Footprint Quantification Requirements for Lithium-Ion Batteries Used in Electrical Energy Storage Systems, led by the China Electronics Standardization Institute, and Greenhouse Gases—Product Carbon Footprint Quantification Methods and Requirements for Lithium Battery Energy Storage Systems, jointly led by Shanghai Envision KES Technology Co., Ltd. and CNESA, entered the public consultation phase. Once released, these standards will provide clear and consistent methodologies for carbon footprint accounting for lithium-ion batteries and energy storage systems.

Conclusion

2025 marked an important year in the standardization of China’s energy storage sector with a set of critical safety standards releasing and implementing, providing essential guidance for the safe development of the industry. As energy storage technologies continue to develop and innovate, sustained collaboration among stakeholders and active participation in standardization efforts will remain critical to fostering a healthy energy ecosystem, supporting China;s energy transition, and advancing green and low-carbon development.

Amazon buys 1.2GW Sunstone solar-plus-storage project from bankrupt Pine Gate

Global tech giant Amazon has been approved as the buyer of the 1.2GW Sunstone solar project in Oregon, one of the largest solar PV projects in the US.

The Sunstone site was developed and previously owned by Pine Gate Renewables, the US independent power producer (IPP), which filed for bankruptcy in November 2025. It includes 1.2GW of solar PV and 1.2GW of battery energy storage system (BESS) capacity, which is ready to build, having received permitting and approvals from the Oregon Energy Facility Siting Council (EFSC).

Amazon’s acquisition was approved by the Bankruptcy Court for the Southern District of Texas, which granted its offer of US$83 million in cash via its specific project subsidiary, Oregon Solar I.

The move follows Amazon’s complaints back in November that an Oregon utility was not supplying sufficient power to its data centre projects in the state, where it has built numerous cloud computing data centres close to the banks of the Columbia River. Once fully operational, the Sunstone solar-plus-storage project will be one of the most significant renewable energy generation projects in the US.

To date, most of Amazon’s energy procurement has been via power purchase agreements (PPAs), and along with fellow Big Tech leviathans Meta and Google, Amazon led US solar power procurement deals in 2024. But the scale of Sunstone, and the fact that it is ready to be built with approvals and permits in place, makes it an attractive proposition for a company whose growing energy demand will be a significant story in the industry over the coming years.

As the power demands of these data centre hyperscalers continue to grow, owning their own power sources might become more common. Last month, Google’s parent company Alphabet announced the acquisition of Intersect Power, an energy project developer, with a view to developing more energy capacity “in lockstep with new data centre load”, Sundar Pichai, CEO of Google and Alphabet, said at the time.

Since declaring bankruptcy, Pine Gate’s roughly 10GW of project assets have been offered to the market, though the company says it has sufficient liquidity to continue operating in the meantime. Earlier this month, Israel-based project developer Nofar Energy bought 1GW worth of Pine Gate’s utility-scale solar assets across the Carolinas, Alabama and Texas for US$285 million.

In December 2025, two large-scale grid-side independent energy storage projects supported by Beijing KeRui were successfully connected to the grid in Inner Mongolia and put into operation: the 500 MW / 2,000 MWh Gushanliang project in Ordos and the 400 MW / 2,400 MWh Bu’erhantu project in Baotou.

Leveraging outstanding engineering execution capabilities, Beijing KeRui’s service team completed the entire process from installation to power delivery in just 50 days—an industry miracle that provided strong assurance for the high-quality and rapid commissioning of both projects. With a combined capacity of 4.8 GWh, the two projects set a new benchmark for the development of China’s independent energy storage sector in terms of large scale, high quality, and accelerated delivery. They inject strong momentum into regional energy structure transformation and provide critical support for building a stable and reliable new-type power system.

In these two flagship projects, Beijing KeRui’s integrated energy storage power conversion and step-up units served as the primary AC-side equipment and played a central role in successful commissioning. Several innovative technologies proved critical to project delivery:

Energy-Efficiency-Oriented Intelligent Thermal Management
The system adopts an innovative multi-tier thermal management strategy centered on “on-demand activation and load matching.” By dynamically aligning transformer cooling requirements with fan operating conditions, the design achieves optimal coordination between auxiliary power consumption and heat dissipation efficiency, significantly reducing unnecessary energy use. In addition, an intelligent heat-exchange buffering design adjusts fresh-air temperature seasonally—mitigating cold shock in winter to protect equipment and pre-cooling intake air in summer to enhance heat dissipation—thereby ensuring long-term stable operation while further refining overall energy efficiency.

Reinforced Structural Design with Integrated Drainage
Through optimization of the converter platform layout, the system enhances overall structural strength while naturally forming efficient drainage channels. This eliminates the need for additional drainage components, achieving dual functionality within a single structure and balancing structural safety with environmental adaptability. The design reflects a philosophy of simplicity, reliability, and efficiency.

Verified Transport Reliability
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.
