Roughly 3,500 grid connected battery storage facilities operate globally as of 2025, with over 100 GW of installed power capacity. The fleet has grown 10x since 2020. This guide covers the count, distribution, and pipeline.
What is counted
The count includes grid connected battery storage facilities above a size threshold (typically 1 MW). Residential and small commercial storage is not included. Fleet composition includes standalone storage and battery paired with solar or wind.
Distribution by region
| Region | Approx MW installed |
|---|---|
| China | ~35,000 |
| USA | ~25,000 |
| Australia | ~4,000 |
| UK | ~4,000 |
| South Korea | ~5,000 |
| Rest of world | ~25,000 |
Growth rate
Size distribution
| Size band | Approx count |
|---|---|
| 1 to 10 MW | ~1,200 |
| 10 to 50 MW | ~1,300 |
| 50 to 200 MW | ~700 |
| 200 to 500 MW | ~250 |
| Over 500 MW | ~50 |
The pipeline
Global pipeline exceeds 400 GW. Expected 200+ GW additions by 2030. See IEA Renewables 2024.
Chemistries
Lithium iron phosphate (LFP) has become dominant chemistry for stationary storage. Nickel manganese cobalt (NMC) still in some sites. Sodium ion emerging. Flow batteries at niche scale.
Applications
| Application | Typical duration |
|---|---|
| Frequency response | Seconds to minutes |
| Load shifting | 2 to 4 hours |
| Peak shaving | 2 to 4 hours |
| Solar plus storage | 2 to 6 hours |
| Grid resilience and backup | Hours to days |
Market economics
Battery revenues come from energy arbitrage, ancillary services, capacity payments, and increasingly resource adequacy. California CAISO, Texas ERCOT, Australia AEMO, and UK National Grid markets have been leading grid battery market design.
Cost trajectory
Cost has fallen 80 percent since 2015. Current CAPEX USD 250 to 400 per kWh installed. Continued reductions expected. Total sector investment approaching USD 100 billion per year globally.
Where the count is going
Expected to double to 7,000 to 8,000 facilities by 2030 with 300 GW installed. Growth driven by renewable integration, grid resilience, and market design maturity.
Frequently asked questions
How many countries have grid batteries?
Over 50 countries with operational facilities.
Which country has most?
China by installed capacity. US by number of facilities.
Are these all lithium ion?
Overwhelmingly. Alternative chemistries emerging but small share.
Do they last long?
15 to 20 years operational life typical.
How much has cost fallen?
80 percent since 2015. Still falling.
Do they compete with pumped hydro?
Different duration. Batteries short duration; pumped hydro longer.
Are they safe?
Modern facilities with thermal management are safe.
Do behind meter systems count?
Usually no in grid facility counts. Residential and commercial batteries tracked separately.
How fast is deployment?
Doubling every 18 to 24 months.
Where can I see data?
The UtilityRadar directory lists battery storage facilities.
Summary
Roughly 3,500 grid battery facilities operate globally with over 100 GW of power. China leads by capacity; US by facility count. Rapid growth continues at doubling times of 18 to 24 months. By 2030 expect 7,000 to 8,000 facilities with 300 GW capacity. Grid batteries are becoming a foundational technology for renewable integration.
