Battery storage deployments statistics: global additions and installed capacity
Global figures give two useful reference points, but they describe separate annual observations. REN21 estimated that 69 GW of new battery storage capacity was deployed worldwide in 2024, bringing estimated installed capacity to 150 GW. The 69 GW is an annual addition; 150 GW is the cumulative installed total. The same report says grid-connected storage represented 78% of the year’s capacity growth, while China accounted for 67% of global new installations. These shares refer to different cuts of deployment: one classifies projects by connection, the other attributes installations by country. REN21, Global Overview
The scale of individual projects is also visible in the 2024 count. Around 17 battery storage installations larger than 1 GW were deployed during that year. This is an approximate count, and the stated threshold concerns installation size; it does not describe the share of total capacity represented by these facilities. REN21 also reported a global average cost for battery storage projects of USD 104 per megawatt-hour in 2024, down by one-third as stated in the report. That is a project-cost metric, not a measure of installed power or annual additions. REN21, Global Overview
| Global battery storage indicator | Reported figure | Reference period |
|---|---|---|
| New capacity deployed | 69 GW | 2024 |
| Estimated installed capacity | 150 GW | 2024 |
| Grid-connected share of capacity growth | 78% | 2024 |
| China share of global new installations | 67% | 2024 |
| Installations larger than 1 GW | Around 17 | 2024 |
The IEA reported a later annual observation: 108 GW of new battery storage capacity was deployed worldwide in 2025. The report identifies Benchmark (2026) as the basis for its 2025 values. This 2025 figure should be read as that report’s estimate for a different year, not as a revision of REN21’s 2024 total. Together, the two observations show deployment at a larger reported scale in 2025, while their different source and period mean they should not be treated as a single continuous dataset. IEA, Technology: Battery storage
Battery storage deployments statistics: deployment mix and project duration
The reported technology and project mix indicates how deployment is configured, as well as how much capacity is being added. The IEA says lithium-iron phosphate (LFP) batteries accounted for around 90% of deployments in 2025. It also reports that around 80% of new global battery capacity that year was utility-scale; the remainder was behind-the-meter capacity installed by commercial and residential consumers. Chemistry share and project scale are distinct attributes, so neither percentage should be read as a breakdown of the other. IEA, Technology: Battery storage
Duration figures provide another dimension. REN21 reported that average battery storage duration in Europe increased from 1.4 hours in 2023 to 2.0 hours in 2024. For new installations in the United States and Canada combined, the reported 2024 average was 3.0 hours. The North American figure is jointly stated for the 2 countries and cannot be assigned to either one alone. REN21, Global Overview
Great Britain’s additions in the final quarter of 2024 were also concentrated in longer-duration capacity: 98% of new battery capacity added in Q4 2024 had a duration of 2 hours or more. That is a share of additions in a particular quarter, not a description of all operational batteries or the annual average duration. IEA, Flexibility
These statistics use different denominators: global deployments by chemistry, worldwide new capacity by scale, a Europe-wide duration average, a joint United States–Canada average for new installations, and a quarterly Great Britain share. Keeping those definitions intact makes the comparisons useful without implying that the figures form a unified ranking. IEA, Technology: Battery storage; REN21, Global Overview; IEA, Flexibility
Battery storage deployments statistics: China’s battery and new-type storage profile
China’s figures require a clear distinction between battery storage and the broader “new-type energy storage” category used in the IEA’s country discussion. The IEA reports that China added about 42 GW and 101 GWh of new-type energy storage in 2024, with an average duration of around 2.3 hours. These additions are not battery-only totals. By the end of 2024, Inner Mongolia led China’s provinces in this category with around 10.2 GW. IEA, Flexibility
The IEA’s 2025 figures for the same broader category are about 66 GW and 189 GWh added, bringing cumulative new-type energy storage capacity to approximately 145 GW by year-end. Standalone energy storage made up 58% of cumulative installations at the end of 2025. The report also tracks duration across the cumulative fleet: average duration rose from about 2.1 hours in 2021 to around 2.6 hours in 2025. These capacity, configuration, and duration measures describe different aspects of the category. IEA, Flexibility
| China indicator | Reported figure | Scope and period |
|---|---|---|
| New-type energy storage additions | About 42 GW; 101 GWh | 2024 |
| Average duration of those additions | Around 2.3 hours | 2024 |
| Inner Mongolia new-type storage capacity | Around 10.2 GW | End of 2024 |
| New-type energy storage additions | About 66 GW; 189 GWh | 2025 |
| Cumulative new-type energy storage capacity | Approximately 145 GW | End of 2025 |
| Standalone share of cumulative installations | 58% | End of 2025 |
A separate figure from China’s National Energy Administration identifies the battery-specific share within the broader category: lithium-ion battery storage accounted for 96.1% of China’s new-type energy storage installed capacity at the end of 2025. This is a technology share within new-type storage, not a statement that all new-type storage is battery-based. The distinction matters when reading the IEA’s broader additions and cumulative totals alongside the NEA’s lithium-ion percentage.

Battery storage deployments statistics: U.S. capacity additions and projects
The U.S. Energy Information Administration reports a rapid build-out of utility-scale battery capacity over several periods. Capacity had an annual average growth rate of 70% over the 3 years to the end of 2025. During January through June 2026, operators added another 8.3 GW, bringing U.S. utility-scale nameplate battery storage capacity to nearly 52 GW in June 2026, according to the latest Preliminary Monthly Electric Generator Inventory cited in the report. The 8.3 GW is a first-half addition; nearly 52 GW is the resulting capacity level. EIA, Battery storage capacity averaged 70% growth over the last three years
An earlier EIA report gives the 2024 reference point: generators added 10.4 GW of new battery storage capacity that year, and cumulative utility-scale capacity exceeded 26 GW. The same report said operators reported plans to add 19.6 GW to the grid in 2025. That planned figure records stated intentions at the time of reporting; it is not a confirmed completed addition. EIA, U.S. battery capacity increased 66% in 2024
| U.S. utility-scale battery indicator | Reported figure | Period or status |
|---|---|---|
| New capacity added | 10.4 GW | 2024 |
| Cumulative capacity | Exceeded 26 GW | 2024 |
| Reported planned grid additions | 19.6 GW | Planned for 2025 |
| New capacity added | 8.3 GW | January–June 2026 |
| Nameplate capacity | Nearly 52 GW | June 2026 |

Named solar-plus-storage facilities illustrate the range of project scales in EIA’s 2026 report. Bellefield Solar and Energy Storage Farm began operations in December 2025 with 500 MW of nameplate power storage. Florida’s Manatee Solar Energy Center, operational since 2021, has 409 MW of battery storage capacity. Gemini Solar Hybrid in Nevada has 380 MW of power storage capacity, which became operational in 2024. These are power-capacity figures for named projects; the cited passages do not provide matching energy-capacity values for these examples.

Battery storage deployments statistics: India’s BESS status and commissioning
India’s Central Electricity Authority (CEA) reports project counts and separate power and energy capacities for battery energy storage systems (BESS) of at least 1 MWh as of September 30, 2026. Its status table distinguishes projects in operation, under construction, awarded, and in tender. The categories represent different development stages and should not be summed as if they all described commissioned capacity. In operation, India had 19 projects totaling 5,317.85 MW and 14,543.20 MWh. CEA, Status of BESS in India as of September 30, 2026
| India BESS status (projects ≥ 1 MWh) | Projects | Capacity (MW) | Capacity (MWh) |
|---|---|---|---|
| In operation | 19 | 5,317.85 | 14,543.20 |
| Under construction | 63 | 27,730.24 | 78,963.92 |
| Awarded projects | 28 | 9,696.50 | 28,913.70 |
| In tender stage | 85 | 20,380.31 | 76,020.84 |
CEA, Status of BESS in India as of September 30, 2026
The construction row includes projects with signed PPA/BESPA, according to the CEA note. The tender-stage figures have a specific qualification: some included FDRE projects have storage capacity that has not yet been finalized. The reported 20,380.31 MW and 76,020.84 MWh therefore need to be read as the table’s tender-stage capacity figures with that qualification, rather than as a fully settled inventory. The separate MW and MWh columns measure power and energy, respectively. CEA, Status of BESS in India as of September 30, 2026
The CEA’s year-wise table provides a commissioning view. Up to March 2025, it records 84.50 MW and 215.60 MWh as present in operation or commissioned. For 2025–26, the corresponding reported figures are 193.35 MW and 574.60 MWh. These year-wise values use the table’s “Present In Operation/Commissioned” fields and complement, rather than replace, the status snapshot dated September 30, 2026.

Battery storage deployments statistics: German and Great British storage capacity
Germany’s 2024 connection applications show the scale of proposed projects, while the operational figures in the same release describe facilities already connected. Network operators received 9,710 applications for battery storage at medium-voltage level and above in 2024; domestic storage facilities were excluded. The proposed facilities represented around 400 GW of planned power capacity and around 661 GWh of storage capacity. These are application totals, not completed deployments, and the release notes that approvals do not ensure implementation. Bundesnetzagentur, 2024 battery storage connection applications
At the time of the November 2025 release, Germany had 921 operational battery storage facilities connected at medium voltage or above. Their net rated capacity was around 2.3 GW, with around 3.2 GWh of storage capacity. The application and operational figures therefore differ in status as well as scale: one is a set of requests received during 2024, the other the reported operating fleet at publication time. Bundesnetzagentur, 2024 battery storage connection applications
For Great Britain, the 2024 Statutory Security of Supply Report described around 4.3 GW of operational grid-scale lithium-ion battery storage and 0.4 GW of operational behind-the-meter batteries in homes and buildings. The same report put the battery storage planning pipeline at 59.0 GW. Operational capacity and pipeline capacity belong in separate readings: the latter is planned capacity, not an operating total. UK Government, Statutory Security of Supply Report 2024
Ofgem’s January 2026 report gives 2 endpoints for Great Britain’s grid battery storage: 0.1 GW in 2017 and 6.8 GW in 2025. These are the figures as presented in that report’s battery storage section. They provide historical context for the build-out without turning the 2017 value into a current measure or adding an unreported annual sequence. Ofgem, State of the Market: Energy Infrastructure Highlights, January 2026
Together, the German and British observations cover distinct measures: connection applications, operating capacity, planning pipeline, and historical grid-capacity endpoints. Their units and status labels determine what each figure can establish.
