Market Trends and Insights

Utility-Scale Procurement Mandates in U.S. Accelerating Gigawatt-Scale Orders

Recurring public procurement gives storage developers a defined route from a policy objective to a project bid. New York’s Public Service Commission directed NYSERDA to conduct at least 3 bulk energy storage procurements, held at least annually, to procure 3 GW. New York issued a request for proposals on July 28, 2025, seeking 1 GW of bulk energy storage toward its statewide 6 GW storage goal for 2030.^[1] On September 23, 2026, NYSERDA announced contracts for 8 bulk storage projects totaling 950 MW and 4,360 MWh. In September 2026, NYSERDA planned a second annual solicitation by year-end. A developer can stage its offers across recurring rounds, which gives the mandate value beyond the first solicitation.

Grid-Forming Inverter Requirements Unlocking Co-Location Value Stacks

Contracted system-strength services give storage developers a commercial proposition beyond shifting electricity between hours. In July 2025, Edify Energy reported that Koorangie in Victoria, Australia, was fully operational at 185 MW/370 MWh with grid-forming inverters. Developed by Edify and owned by Sostoneo Infrastructure Partners, the battery secured a 20-year AEMO agreement for 125 MW of system-strength services. A separate 15-year offtake with Shell Energy Australia supported the energy side of the project. For developers, these distinct contracts show how a network service requirement can support purchasing a particular inverter capability alongside storage capacity. Edify said the grid-forming technology lets the battery provide both energy storage and system-strength services in the Murray River region of Victoria, where grid constraints have limited renewable energy exports.

PV-Plus-Storage PPA Price Parity in Australia & Chile

When solar-plus-storage can match the price of a competing power offer, storage becomes part of the contracted electricity service. For buyers in Australia and Chile, a useful comparison must hold the delivery profile constant rather than compare differently timed electricity. A paired project that meets that test can compete for a power contract without requiring the buyer to justify a separate battery investment. The storage provider’s opportunity then depends on delivering the battery contribution needed for the agreed profile within the combined price. Where such parity holds, storage volumes would follow the size and timing of the power contracts that solar developers win rather than standalone battery tenders.

EU & U.S. Battery Supply-Chain Acts Creating Domestic Manufacturing Pull-Through

Manufacturing incentives make the location and eligibility of component production commercially significant for storage suppliers. U.S. Section 45X provides credits for qualifying domestically produced battery components sold to unrelated buyers, subject to prohibited-foreign-entity material-assistance restrictions for taxable years beginning after July 4, 2025. The European Commission’s 2025 IF25 call included energy-storage component manufacturing among eligible clean-technology activities, with grants expected in the first quarter of 2027. Manufacturing projects must exceed EUR 2.5 million (USD 2.92 million) in capital expenditure to qualify under that topic. For storage developers, a supplier backed by production credits or manufacturing grants can offer a stronger domestic sourcing proposition. These incentives can pull orders toward qualifying battery plants, connecting manufacturing support to the procurement of storage systems.

Lithium & Graphite Processing Bottlenecks in Indonesia and Africa

In 2025, the UK government reported that Mozambique and Madagascar produced graphite while all midstream processing was done in China. The same report identified a lack of African lithium refining capacity alongside emerging production in Zimbabwe and the Democratic Republic of the Congo. For cell makers and storage integrators sourcing through these routes, the reported structure puts graphite processing outside the producing countries and leaves lithium chemicals dependent on refining capacity beyond African mine production.

Fire-Safety Code Tightening (UL 9540A, NFPA 855) Inflating Balance-of-Plant Costs

Fire compliance can tie deployment costs to the proposed installation rather than the battery package alone. NFPA 855’s 2026 edition and the 2024 International Fire Code require representative-system fire testing in certain situations, using UL 9540A as the test method. San Diego County Fire Protection District’s April 2026 guidelines for covered lithium-ion BESS facilities exceeding 600 kWh require test results and supplemental reports.^[2] An additional unit-level large-scale fire test applies when cell- or module-level testing shows flammable gas generation. Projects relying only on UL 9540A’s 2019 edition may be considered with additional protection measures and early district consultation. That conditional route leaves developers exposed to site-protection and validation work, so a lower battery price cannot eliminate the expenditure needed for an acceptable installation.

Battery Energy Storage System (BESS) Market Segment Analysis

Lithium-ion was the largest segment, with an 88.12% share of the market in 2026. China’s National Energy Administration reported that lithium-ion supplied 96.1% of the country’s installed new energy storage capacity at the end of 2025. The NEA grouped compressed-air, flow-battery and flywheel storage within the small remainder of installed new energy storage capacity.

Lithium iron phosphate (LFP) is the fastest-growing segment, with a forecast 19% CAGR over 2027-2032. The 2,000 MWh Tongliao standalone storage project in Inner Mongolia entered operation in November 2025 using CATL’s 5 MWh LFP battery energy storage system. The station was developed as a peak-shaving source supporting the large renewable energy base in eastern Inner Mongolia. Here, the LFP choice serves a plant-level peak-shaving duty, with CATL’s 5 MWh system as the equipment unit within the station.

On-grid systems represented a 77.19% battery energy storage system (BESS) market share in 2026. The IEA reported that utility-scale batteries accounted for around 80% of global new battery capacity in 2025. Innergex’s Hale Kuawehi solar-plus-storage project began commercial operations on March 25, 2025, supplying up to 30 MW of renewable energy to the Hawai‘i Island grid with a 120 MWh battery system. Innergex sells the project’s energy to Hawaiian Electric under a 25-year power purchase agreement, tying this battery application to a long-term utility supply relationship.

Off-grid (micro-grid, hybrid) storage is the fastest-growing segment, with a forecast 18.4% CAGR over 2027-2032. Saudi Arabia’s Red Sea multi-utility project reached full commercial operation in August 2026 with 1,225.4 MWh of battery storage. That milestone completed the wider utility package, while its solar and storage assets had been progressively commissioned since 2023. The project operates independently of the national transmission network to serve a tourism destination and supporting infrastructure. Battery demand in this independent network follows the requirements of the destination’s complete utility service.

Battery packs and racks accounted for a 62.08% share of the battery energy storage system (BESS) market size in 2026. In March 2025, LG Energy Solution signed an agreement to supply PGE with 981 MWh of grid-scale ESS batteries for Żarnowiec, Poland, with deliveries scheduled for 2026-2027. The agreement also encompassed containerized battery systems and EPC services with European partners. This places the battery component within a broader plant-delivery scope, connecting the equipment order to implementation responsibilities.

Energy management software (EMS) is the fastest-growing segment, with a forecast 19.8% CAGR over 2027-2032. In August 2026, Solarmarkt Group selected Stem’s PowerTrack EMS under a 5-year agreement for 2 Hungarian hybrid projects. Each project adds an 80 MWh BESS to an existing solar plant, with Solarmarkt as owner and Pannonwatt as EPC partner. The selected platform combines energy management, power plant control and SCADA functions within that solar-and-storage scope. The 5-year term covers both projects, so the software provider has a contractual role as storage is added to the existing solar plants.

The 101 to 500 MWh range was the largest segment, with a 45.3% market share in 2026. Apex Clean Energy announced commercial operation of Texas’s 100 MW/200 MWh Great Kiskadee Storage in February 2025, the first operating asset of SA Grid Solutions, its joint venture with SK Gas and SK Eternix. In July 2025, AMEA Power commissioned Egypt’s first utility-scale BESS, a 300 MWh facility in Aswan Governorate fully powered by solar PV. Great Kiskadee opened a joint venture’s operating portfolio, and Aswan introduced utility-scale storage in Egypt, so this range served as an entry point for a new owner and a national deployment category.

Above 500 MWh is the fastest-growing segment, with a forecast 18.25% CAGR over 2027-2032. In February 2026, 6 New South Wales BESS projects were awarded Long-Term Energy Service Agreements. Their listed maximum capacities ranged from 870 MWh to 3,500 MWh, with 12 GWh of expected combined storage and continuous dispatch exceeding 8 hours. Separately, Adani Green Energy expanded operational BESS capacity at Khavda, India, from 3.55 GWh in June 2026 to 6.63 GWh in October 2026. The New South Wales awards link projects above 500 MWh to prospective dispatch beyond 8 hours, while Khavda demonstrates operating multi-GWh capacity at one location.

Utility applications were the largest segment, with a 56.01% share of the market in 2026. U.S. utility-scale battery installations exceeded 2.3 GW and reached 6.8 GWh in the first quarter of 2026. The American Clean Power Association attributed much of that quarter’s growth to projects delayed from 2025, when developers focused on tax-incentive eligibility deadlines, so first-quarter installations reflect deferred completions more than a steady quarterly pace.

Residential storage is the fastest-growing segment, with a forecast 19.35% CAGR over 2027-2032. Australia recorded 276,011 battery installations in January-June 2026 in the Clean Energy Council’s application-based series, which includes some applications progressing through compliance review. The series rose 52% from July-December 2025, demonstrating substantial uptake in a national home-battery program context. Germany presented a different recent demand pattern, with BSW-Solar’s preliminary balance reporting an approximately 8% fall in home-storage demand in 2025 from 2024. These divergent country readings show that residential storage demand moves country by country, so supplier opportunity depends on active adoption channels rather than on a uniform household trend.

Geography Analysis

Asia-Pacific Battery Energy Storage System (BESS) Market

Asia-Pacific accounted for a 50.09% share of the battery energy storage system (BESS) market size in 2026. China added just over 63 GW of battery capacity in 2025, about one-third more than in 2024. Australia’s Cheaper Home Batteries Program had approved 78,000 April 2026 installations representing 2.8 GWh by the end of the second quarter of 2026. Together these examples show demand arriving through 2 channels, large-scale additions in China and an approval-based home-battery program in Australia, so suppliers reach both project developers and household buyers.

Middle East and Africa Battery Energy Storage System (BESS) Market

Middle East and Africa is the fastest-growing geography, with a forecast 19.45% CAGR over 2027-2032. In July 2026, AMEA Power announced commissioning of the 600 MWh BESS and 500 kV substation at its 1,000 MW solar-plus-storage project in Benban, Egypt. Phased dispatch to the Egyptian Electricity Transmission Company’s grid was underway at that announcement, while full commissioning of the overall project remained prospective. The battery and its grid infrastructure form a linked delivery scope, since individual project blocks can begin dispatch before the entire renewable complex is fully commissioned.

North America’s operating base included 43.6 GW of utility-scale battery capacity in the United States at the end of 2025. In Europe, European Energy commenced commercial operation of Denmark’s Kvosted solar and battery park in December 2025, with 200 MWh of storage. South America’s standalone deployment included Atlas Renewable Energy’s BESS del Desierto in Chile, inaugurated in April 2025. The Danish and Chilean examples distinguish adding storage within a generation project from developing a separate storage asset, while the U.S. reading establishes a substantial utility fleet.

Regulatory Framework and Outlook

The table compares selected jurisdictions from the perspective of integrated battery manufacturers supplying and developing stationary BESS projects. The United States entry covers the private, non-opt-in permitting pathway in unincorporated San Diego County, with County Fire Authority enforcement outside fire-protection districts and district fire chiefs responsible within their districts. The ratings compare the requirements’ effects on market access and project economics, while the direction captures enacted or proposed changes relevant to that participant.

The United States local pathway faces a technical-study duty, while San Diego County’s 2026 draft zoning amendment proposed prohibiting covered facilities above 600 kWh in residential zones. Germany combines registration with a scheduled February 18, 2027, passport obligation for industrial batteries above 2 kWh, supporting its hardening direction. China’s easing assessment reflects the capacity-price mechanism for grid-side independent new energy storage, which the NEA cited on July 20, 2026, as established by a national notice and supporting cost recovery alongside the connection framework. Brazil and Egypt retain identifiable 2026 authorization routes, supporting continuity in their approval requirements, while Brazil’s July 2026 draft auction consultation concerned standalone capacity procurement rather than replacing authorization.

Value Chain Stages

The comparison follows value capture from system supply through commissioning and operating support. In 2025, NTR selected Fluence to supply Gridstack Pro 5000 for the Uusnivala project in Finland, which the April 2025 announcement described as ready to build. That arrangement separates the project investor’s role from equipment supply, while Fluence’s engineering, installation, commissioning and service offerings show how additional delivery responsibilities can be bundled with a storage system.

Fluence’s service plans can include managed monitoring and maintenance or support that equips customer teams through training. Managed maintenance assigns recurring work to the service provider, while training supports tasks retained by the operator. The operator’s retained staffing responsibilities therefore determine which support package fits that division of work.

Key Opportunities for Market Participants

The comparison separates storage opportunities by the service purchased, the counterparties served and the obligation a supplier must deliver. Recent procurement in Australia, India and Canada provides concrete demand signals for long-duration storage, contracted energy and utility flexibility, respectively. Suppliers can target equipment, project development or operating services within those requirements, with the feasible commercial role determined by the contract’s delivery conditions.

The central opening is to package battery capacity around a duty that a utility can contract and verify. Energy procurement gives a developer a different commercial role from selling equipment, because the contracted product is delivered energy rather than the battery itself. Equipment suppliers can address that distinction by supporting the developer’s performance obligation, aligning system design and operating scope with the service being purchased.
