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.

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.

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.

“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.

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.
