BESS technology continues to advance, but the energy industry needs to change its thinking about O&M to capture the full potential, writes Jeremy Williams of IHI Power Services.

Q2 2025 saw the sharpest jump in battery energy storage system (BESS) prices since 2021, according to procurement platform Anza Renewables’ Q2 US energy storage pricing insights report.

After months of deliberation and analysis, the California Energy Commission (CEC) has approved the first project reviewed as part of its opt-in certification scheme.

US tax credits for energy storage projects could be retained even if solar PV, wind and electric vehicle (EV) incentives face cuts.

The question of where the cells in a BESS are from ties in to safety, performance, design and, increasingly, potential tariffs.

A trio of major players in the battery storage system integration space have unveiled recent Large-Scale Fire Testing (LSFT) results.

Power company AES Corporation has completed construction of the 1,000MW Bellefield 1 project in Kern County, California. The project includes 500MW of solar and 500MW/2,000MWh of battery storage.

Prospect14 became the latest US renewable energy developer to have a hybrid storage project application scrutinised and ultimately rejected.

In Texas, two companies, Energy Vault, recognised for its gravity energy storage technology, and Agilitas, known for smaller-scale projects in the Northeastern US, have put utility-scale energy storage projects in the state into operation.

According to specialist renewable energy insurance company kWh Analytics’ 2025 Solar Risk Assessment, concern around battery energy storage system (BESS) safety has risen following recent fire incidents.
