Industry Developments:

Deployment and market growth

1. Globally, about 49.4 GW/136.5 GWh of new grid‐scale BESS came online in the first nine months of 2025, a 36% increase in energy terms over the same period in 2024.​

2. In the US, storage added more than 2 GW across all segments in Q1 2025 alone and reached 5.6 GW of new capacity in Q2, with utility‐scale projects accounting for the majority of installations.​

3. EIA expects 18.2 GW of new utility‐scale battery storage to be added to the US grid in 2025, setting another record and making storage one of the dominant new capacity types alongside solar.​

Economics and cost trajectories

1. A 2025 NREL update shows utility‐scale battery cost projections tracking near the low‐cost scenario from its 2023 report, reflecting lower current cost estimates, especially for lithium‐ion systems.​

Policy, procurement, and VPP integration

1. Q1 and Q2 2025 saw multiple US states refine storage/VPP rules, addressing size thresholds, discharge limits, dual‐participation, test events and emergency triggers, which directly affect how grid‐scale batteries can be aggregated and dispatched.​

2. Utilities continue large procurement rounds for utility‐scale storage, as documented in 2025 updates on storage solicitations; developers are rushing some projects to construction ahead of evolving trade and tax rules, even as tariffs and supply‐chain risks add uncertainty.​

3. VPP‐oriented policy work positions grid‐scale batteries as core flexible resources alongside aggregated behind‐the‐meter assets, with a 2025 DOE "Liftoff" update highlighting storage‐rich VPPs as a scalable path to meet peak needs.​

Technology and operational performance

1. CAISO's 2024/2025 special report on battery storage shows multi‐GW of batteries now performing as critical capacity and flexibility resources, shifting midday solar overgeneration into evening peaks and increasingly providing reliability services.​

2. Developers and OEMs are pivoting from purely 1-2‐hour systems toward longer‐duration configurations to support grid stability, with broader BESS market forecasts calling for strong growth in 4‐hour and multi‐hour use cases.​

3. Utility‐scale batteries are now used widely for frequency regulation, peak shaving, congestion relief, and as non‐wires alternatives, moving from pilot status to "foundational infrastructure" in high‐renewables regions.

Forecast Projection:

The Global Grid Scale Battery Market is poised for significant growth between 2025 and 2032.

China Huadian 1 GW / 4 GWh LFP BESS, China

1. Billed as the largest single‐phase LFP grid‐scale system yet online, with construction starting only in Q1 2025 and commissioning reported around August, underscoring how fast Chinese mega‐projects are now being built.​

Collie BESS Phase 2, Australia - 341 MW / 1,363 MWh

✅ Adds to Phase 1 such that combined Collie capacity reaches about 560 MW / 2,240 MWh, giving Western Australia one of the world's largest battery hubs for shifting solar into evening peaks.​

Egypt's largest standalone BESS - 150 MW / 300 MWh

✅ A dedicated 150 MW / 300 MWh plant commissioned mid‐2025, using 72 containerised battery units and intelligent control systems to support grid stability and solar integration.​

US Q2 2025 commissioning wave - 4.9 GW / 15 GWh utility‐scale

✅ In Q2 alone, roughly 4.9 GW / 15 GWh of utility‐scale storage came online in the US, with Texas, California and Arizona accounting for about three‐quarters of capacity; individual projects range from 100-300 MW class systems rather than a single mega‐flagship.​

✅ India's first utility‐scale standalone BESS - 20 MW / 40 MWh, Delhi

✅ Commissioned in early 2025 as South Asia's largest standalone BESS at the time, designed to improve local grid reliability for tens of thousands of consumers and serve as a demonstrator for larger Indian projects now in the pipeline.
