In April 2025, Narada Power released the 783Ah ultra-high capacity energy storage solid-state battery. Through three core technological breakthroughs—“flexible two-phase oxide solid electrolyte,” “multi-layer heterogeneous composite structure design,” and “in-situ electrolyte film formation”—the battery’s energy density and safety performance achieved a leap forward.

Australia: Federal Government’s CIS Launches Two Major Tenders Targeting WA Renewable Energy and Storage

The Australian Government’s Capacity Investment Scheme (CIS) is set to open two significant tenders in late August 2025, aiming to secure 1.6 GW of renewable energy generation and 2.4 GWh of dispatchable capacity for Western Australia’s Wholesale Electricity Market (WEM). Known as Tender 5 and Tender 6, these competitive processes will target projects connecting to the South West Interconnected System (SWIS). Tender 5 focuses on renewable generation—such as solar and wind—with an indicative target of 1,600 MW, while Tender 6 seeks 2,400 MWh of dispatchable capacity, including battery storage with a minimum two-hour duration. Both tenders require projects to have a minimum capacity of 30 MW and demonstrate credible pathways to reach commercial operation by December 31, 2030. Projects with earlier operational dates and robust development plans will be rated more favorably. AusEnergy Services Limited (ASL), formerly AEMO Services, will manage the tender process, including assessing project merit and social licence, while the Minister for Climate Change and Energy holds final approval authority. The scheme aims to bolster energy reliability and accelerate Australia’s renewable transition (according to the reference article and CIS Market Briefs).

Both tenders will implement a streamlined single-stage bidding process—consolidating technical and financial proposals—intended to shorten the tender duration from nine months to approximately six. Registrations are expected to close by late September 2025, with the question and answer period concluding shortly before bids close in late October. This approach is designed to increase efficiency, deliver results earlier, and support timely signing of Capacity Investment Scheme Agreements (CISAs). Additionally, the government has integrated social licence requirements emphasizing meaningful engagement with First Nations and regional communities. From these tenders onward, recipients will publicly report labour and workforce practices, enhancing transparency around employment conditions. A webinar slated for early September will further clarify tender details and procedural changes. The CIS continues Australia’s ambitious goal to install 40 GW of renewable and dispatchable capacity nationwide by 2030, addressing energy gaps from coal and gas retirements.

These concurrent tenders mark a key step in expanding Western Australia’s renewable infrastructure. They complement prior CIS rounds, which awarded contracts for over 650 MW and nearly 2,600 MWh of dispatchable capacity across battery projects in the state. Final tender guidelines are expected shortly, with successful projects announced by March 2026. The federal government’s commitment underlines its strategy to achieve 82% renewable electricity by 2030 while ensuring reliable energy supply for households and businesses across Australia. Further updates and detailed allocation information will be available as the tenders progress.

The report states that ARENA is well-placed to support energy storage technologies. Image: Eku Energy.

Australia’s Department of Climate Change, Energy, the Environment and Water has released the draft National Electricity Market (NEM) Review, signalling significant reforms aimed at integrating more renewable energy while safeguarding grid stability. Led by Associate Professor Tim Nelson, the independent review panel identifies energy storage as essential to managing a grid increasingly dominated by variable renewable energy (VRE). The report highlights risks of supply shortfalls in South Australia and New South Wales from 2026–28, underscoring the need for large-scale solutions like the 850MW Waratah Super Battery and long-duration energy storage (LDES) systems. Central to the proposals is an Electricity Services Entry Mechanism (ESEM), designed to provide long-term investment certainty for renewable and firming projects by targeting financial risks in later project years, integrating with derivatives markets, and embedding the scheme permanently in the National Electricity Law.

According to the draft, reforms should also boost participation in Essential System Services (ESS) such as frequency control and voltage regulation, traditionally supplied by fossil-fuel plants. The review recommends market designs, pricing mechanisms, and regulatory changes to enable batteries, pumped hydro, and other zero-emissions firming technologies to deliver these services. The Australian Renewable Energy Agency (ARENA) is flagged as well-positioned to accelerate deployment of scalable, low-emissions storage solutions, with immediate government action urged to bridge funding gaps. To improve market efficiency, the report proposes a permanent Mandatory Market Making Obligation (MMO) to enhance liquidity and price transparency in NEM derivatives, benefiting smaller retailers and supporting long-term investment signals in renewables and storage.

The draft also addresses the growing influence of flexible demand and “hidden” resources like rooftop solar on price formation and system stability, calling for reforms to improve visibility, bidding practices, and market price setting. Consultation closes 17 September 2025, with the final report expected by year’s end, according to the department.

Spain Channels €148.5M into Battery-Backed Renewable Projects

On August 6, 2025, Spain’s Ministry for the Ecological Transition and Demographic Challenge (MITECO) approved €148.5 million in grants for 199 cutting-edge renewable energy installations, all paired with battery storage. According to the ministry, the funded projects will deliver 299.6 MW of mostly photovoltaic generation alongside 351.6 MWh of storage capacity, creating a more stable supply from intermittent solar power. Catalonia leads with 79 approved projects, followed by the Valencian Community (30), Castilla y León (17), and Andalusia (13), signalling broad regional participation in the shift toward renewables with built-in storage. The grants form part of Spain’s RENOINN programme, financed by the EU’s NextGenerationEU Recovery and Resilience Facility, which requires recipients to combine generation with storage for most funding lines. The scale and scope of this commitment mark a strong signal of momentum for Spain’s emerging energy storage sector.

Agrivoltaics with storage—solar arrays integrated into farmland—secured the largest share: €77.1 million for 62 projects, including 19 in the Valencian Community and 13 in Catalonia. These sites will pair crop cultivation with battery-backed solar production, and grantees must report annually for five years on both energy output and agricultural impacts. Floating solar systems, mostly for agricultural irrigation ponds, received €10.1 million for 11 self-consumption plants. Another €23.4 million went to 27 projects integrating renewables into infrastructure such as transport corridors, brownfields, and former industrial sites, adding 45.6 MW and 133.2 MWh of storage. For community energy, €18.2 million was allocated to 67 shared self-consumption projects aimed at 4,000 vulnerable users, combining resilience with potential cost savings.

The Institute for Diversification and Saving of Energy (IDAE) will manage the funding call, oversee technical assessments, and monitor performance over five years. By tying storage to nearly every funded project, MITECO’s strategy moves Spain’s renewable expansion beyond simple generation toward a more flexible, dispatchable model that can deliver power when demand—not daylight—peaks.

FlexGen Gains Court Approval to Acquire Powin Assets, Expanding Global Energy Storage Reach

FlexGen Power Systems has secured approval from the U.S. Bankruptcy Court for the District of New Jersey to acquire key assets from Powin, a fellow energy storage company currently under Chapter 11 protection. The decision marks a major step forward for FlexGen, allowing it to absorb a significant portion of Powin’s business and technology. According to FlexGen’s announcement on August 6, the acquisition includes all of Powin’s intellectual property—both hardware and software—as well as its IT systems and spare parts inventory. Once the transaction is finalized, FlexGen’s portfolio will expand to more than 25 GWh of battery energy storage projects across 200 deployments in 10 countries. This move strengthens FlexGen’s position as a global leader in battery energy storage systems (BESS), further integrating its software capabilities with Powin’s hardware strengths.

The acquisition comes amid broader industry shifts, with Powin having filed for bankruptcy in June 2024 due to financial struggles linked to U.S. tariff policies and uncertainty around federal clean energy incentives. The company had previously warned of possible layoffs and operational shutdowns by July. To sustain operations during the bankruptcy process, Powin secured a $27.5 million DIP loan—backed by FlexGen as the stalking horse bidder. FlexGen’s motivation to acquire Powin appears rooted in strategic synergies: while FlexGen brings 15 years of software and microgrid control expertise, Powin contributes strong hardware integration and battery management technology. FlexGen’s leadership emphasized that the integration will ensure service continuity for Powin’s clients and improve system performance using its HybridOS® software and Remote Operations Center.

With this court approval, FlexGen now prepares to finalize the deal and absorb Powin’s operations, aiming to deliver enhanced grid reliability and uptime for customers worldwide.

Inside the Surge Toward Large-Capacity Storage Cells: What’s Driving the 500Ah+ Race

As the global energy mix accelerates its transition toward renewable energy, energy storage systems—key to balancing grid fluctuations and enhancing the consumption of green electricity—are facing increasingly urgent demands for cost reduction and efficiency improvement. In this context, increasing cell capacity has become a key focus of industry competition. From 280Ah and 314Ah to the emergence of 500Ah+ and even 600Ah+ products, the cell iteration cycle has significantly shortened. However, while large-capacity cells can reduce system costs, they also face a series of technical challenges and must undergo rigorous verification by investors regarding their safety and economic performance over the entire lifecycle. This article will analyze the internal logic and future outlook of large-capacity cell development from multiple dimensions, including technology, market, and manufacturing processes.

01 Large-Capacity Cell Deployment

As the need to reduce costs and improve efficiency in energy storage becomes increasingly urgent, cells are developing toward higher capacities. Currently, nearly 20 cell manufacturers have launched or planned 500Ah+ large-capacity cell products, and the iteration process is accelerating.

It took about three years for energy storage cells to evolve from 280Ah to 300+Ah, while it only took two years for 300+Ah cells to reach 500+Ah and even 600+Ah.

CATL is consolidating its dominant position in large-scale energy storage stations with its 587Ah cell, aiming to enhance customer service capabilities through a "high-capacity standard"; Sungrow, as a system integrator, has defined the 684Ah cell to build differentiated competitiveness through "cell-system" co-design; CALB and Rept Battero are focusing on 392Ah cell specifications to seek rapid market entry.

It is an industry trend for cell and system integration companies to increase cell capacity. However, whether project investors truly endorse large-capacity cells is still too early to determine and requires continuous market validation to assess the actual strength of large-capacity cells.

02 Why Develop Large-Capacity Cells

Cells are the most valuable component of the entire energy storage system and the main “battlefield” for ongoing iteration in storage integration technology, directly determining system configuration and integration solutions.

The fundamental purpose of building large-capacity cells is to reduce the number of cells, components, and footprint used in energy storage systems by increasing cell capacity, thereby lowering the overall investment cost of energy storage stations.

For example, CATL’s 587Ah cell can reduce the number of system components by 20% and increase space utilization by 30%. With fewer cells, the costs of connectors, fuses, BMS harnesses, and other auxiliary materials are significantly reduced.

From a system O&M cost perspective, for energy storage systems with the same capacity, the significantly reduced number of large-capacity cells means fewer potential failure points, lower monitoring and maintenance complexity, and reduced lifecycle O&M costs.

03 Technical Challenges of Large-Capacity Cells

During cell charging and discharging, when capacity exceeds 500Ah, electrode thickness must increase from 150μm to 250μm. The diffusion distance of Li⁺ in the LiFePO₄ lattice becomes longer, impeding internal electrochemical reactions and causing increased polarization voltage near the end of charging, which accelerates cell aging and shortens lifespan. Furthermore, increased polarization voltage at the end of charging generates excessive internal heat, potentially leading to thermal runaway, causing fires, explosions, and other safety incidents.

In manufacturing, electrode sheets require extremely high coating uniformity. As electrode size increases, thickness deviation also increases. The welding area of tabs in large-capacity cells is larger, increasing the probability of false welding or burn-through. During formation, uneven current distribution may cause inconsistent SEI film formation, affecting lifecycle consistency.

In system integration, large-capacity cells pose challenges in refined management and risk control. In a large-capacity system, the importance of a single cell increases significantly. In a 314Ah system, a single cell failure affects about 0.3% of cluster capacity, while in a 684Ah system, a single cell failure may affect 0.6% of cluster capacity. The long heat dissipation paths and high thermal resistance in large cells hinder quick heat transfer, demanding high reliability in thermal management design. To improve cooling, higher flow and pressure liquid cooling pumps are needed to ensure rapid circulation of coolant, and the related thermal components must offer superior heat dissipation performance and reliability.

At the application level, 314Ah systems are already mature. For investors, the safety, lifespan, and stability of large-capacity cell integration solutions are still based only on supplier reports without reliable operational data. The actual performance of large cells in operation remains uncertain, and in the short term, accepting large-cell integration solutions may face considerable challenges.

Therefore, the large-scale application of large-capacity cells will not happen overnight. Cell manufacturers will weigh process difficulty, cost, and market acceptance, while investors will consider safety, economic benefits, and convenience of cell replacement.

04 Manufacturing Process

Due to differences in R&D direction and technical accumulation among companies, there are divergent approaches to manufacturing large-capacity cells. The main manufacturing processes for 500Ah+ cells are winding and stacking.

Advantages of the stacking process: Stacked electrode groups are layered structures without bending, making full use of case space. Compared to winding, stacking offers higher energy density, lower internal resistance, lower temperature rise, better rate performance, and improved safety.

Disadvantages of the stacking process: Electrodes must be cut before stacking, and the cut surfaces may have burrs and dust, creating risk of internal short circuits. High precision is required in burr and alignment control during processing. High-precision semi- or fully-automated equipment is needed for trimming control, resulting in higher equipment and production costs.

Advantages of the winding process: The roll core is formed through high-speed rotation with minimal mechanical action and short auxiliary time, yielding high production efficiency. Winding requires only two spot welds per cell and is relatively simple to operate. Winding machines are cheaper, with lower investment cost.

Disadvantages of the winding process: With single tabs on positive and negative electrodes, part of the voltage is lost in internal polarization, resulting in poor charge/discharge rate performance. During winding, uneven tension on electrodes and separators can cause wrinkles. Electrode expansion and contraction impact cell cycle life.

05 Standardization or Diversification

After the issuance of Document No. 136, the marketization of energy storage station investment and operation accelerated. Investors are focusing more on the full-lifecycle revenue of storage equipment. Since the industry has reached consensus on “thermal runaway warning thresholds” and “cycle life bottom lines” for cells, a safety baseline has been established for system adaptation across different cell sizes. Additionally, on the communication layer, BMS-cell communication protocols and state monitoring parameters are gradually being unified, enabling different cell sizes to connect to the same monitoring system. Against this backdrop, the evolution of storage cell size is not a binary choice but a dynamic process of maintaining differentiated innovation within a unified framework.

Therefore, in the short term, differences in priority regarding capacity, density, cost, and safety across various markets drive divergent design logic. A competitive structure will emerge with 314Ah, 392Ah, and 500Ah+ cells complementing each other. The 314Ah and 392Ah cells will continue to dominate the 2h and 4h storage markets, while 500Ah+ will focus on long-duration storage above 4h. Furthermore, as market competition intensifies, companies with different market standings are adopting divergent strategies to capture market share. Leading enterprises promote single-standard products to redefine the next generation of cell size; second- and third-tier companies pursue multi-specification strategies to meet diverse customer needs, resulting in short-term intensification of cell size diversification and a blooming landscape.

In the long term, as storage duration increases and large-cell manufacturing advances, whether it’s 530Ah, 587Ah, or 684Ah cells, their application performance across various markets and their impact on station and system design will be critical. Integrators will choose appropriate technical paths based on these factors, further reinforcing size diversity. The winding process, with its lower overall manufacturing cost, will target the sub-600Ah market, while stacking—offering uniform internal stress distribution and low heat generation—will aim at the 600Ah+ segment.

06 Trend Outlook

Cells should not simply pursue larger capacity but also consider investor acceptance. Therefore, large-cell development should start from aspects such as energy storage systems, AC-side distribution, and post-operation and maintenance, exploring technical innovation paths to reduce LCOS costs.

Although 500Ah+, 700Ah+, and even 1000Ah+ cells are emerging one after another, large-capacity cells have yet to achieve large-scale deployment. It is still too early to determine which type will become the mainstream next-generation product. Ultimately, the winning cell type will depend on a company’s deep understanding of system boundaries, rational judgment of technical tipping points, and flexible responsiveness to application scenario demands.

Galp has kicked off construction on five new battery energy storage system (BESS) projects in Spain and Portugal, marking a major step in its clean energy strategy. According to the company, the installations will total 74MW/147MWh and connect directly to solar power plants. Four of the projects are located in Portugal and will add 60.5MW/120.4MWh of capacity near Galp’s Alcoutim solar farms. These are being partially funded through a €100 million Portuguese government scheme backed by the EU’s Recovery and Resilience framework. A fifth BESS, sized at 14MW/28MWh, will be built in Manzanares, Spain. All systems will use Sungrow’s PowerTitan 2.0 technology and feature grid-forming inverters, enabling them to provide advanced services such as fast frequency response, voltage regulation, and synthetic inertia.

Galp’s Control Center will oversee the real-time operation and optimization of the new systems, managing both energy production and storage across Portugal and Spain. This builds on Galp’s earlier 5MW/20MWh project in Portugal, developed with Powin and Hitachi before Powin entered administration. With the ability to deliver multiple ancillary services, Galp is positioning these BESS projects to play a pivotal role in the Iberian grid as renewables expand. Spain recently launched a €700 million energy storage incentive program, while Portugal announced an additional €400 million investment last week aimed at boosting grid stability and BESS deployment. Both nations are clearly moving to address rising grid challenges, especially after a region-wide blackout earlier this year spotlighted the need for more robust infrastructure.

The integration of solar and storage continues to gain traction in the region. A recent hybrid solar-plus-storage power purchase agreement between Zelestra and EDP underscores market momentum. While Spain’s additional funding plans remain in discussion, the region’s shift toward hybrid, grid-forming systems is well underway.

Romania: Trina Storage to Deliver 65MWh Battery System for Romanian Energy Project

Romania BESS project, Allview, Trina Storage

Trina Storage is set to supply a 65MWh battery energy storage system (BESS) for a new project in Romania, marking its first deployment in the country. The initiative, located in Toplița, Harghita County, is being led by Allview, a subsidiary of Visual Fan, which will oversee engineering, procurement, and construction. Trina Storage, the energy storage arm of Chinese solar company Trinasolar, will provide 16 Elementa 2 battery units for the DC-side of the system. The project is part of a broader multi-gigawatt-hour expansion strategy across Europe. According to Trina Storage Europe’s head Gabriele Buccini, the Toplița deployment signals a long-term commitment to Eastern Europe’s growing energy storage market.

Allview will also handle the full AC scope, including the power conversion system and medium-voltage infrastructure. The system is being developed for Renovatio Trading, a power services and trading firm that secured support under Romania’s EU Recovery and Resilience-backed capex scheme. This national initiative, finalized in late 2024, aims to fund up to 2.5GWh of BESS capacity. Since its rollout, several large-scale projects have moved into development with key players such as Güri̇ş Group, R.Power, Electrica, and Hidroelectrica. Renovatio’s Toplița project represents a total investment of RON 126.5 million (€24.5 million) and is expected to be operational by June 2026.

The project’s momentum coincides with Romania’s recent regulatory shift. Last month, the National Energy Regulatory Authority (ANRE) ended the double taxation of energy storage, removing a major financial barrier. Meanwhile, other companies, including China-based Hithium, are also targeting Romania for long-duration energy storage ventures. While Trina Storage expands its presence, the broader sector is gaining traction through increased policy support and international investment.
