US battery fleet grows 59% with nearly 14 GW added in 12 months, says EIA Data from the US Energy Information Administration (EIA) shows that battery energy storage and solar are dominating capacity additions, while fossil fuel capacity continues to net a decline. Another 22 GW of storage is projected for the coming year.

“It’s a miracle we have any storage projects in Germany at all” Interview: Germany’s Federal Network Agency (Bundesnetzagentur or BNetzA) recently published an FAQ on grid connections for large-scale battery storage. It says that big battery systems require two separate procedures — one for charging (grid draw) and one for discharging (grid feed-in). Attorney Britta Wißmann from Watson Farley & Williams explains what this means for ongoing projects and existing grid connection approvals.

Most home battery storage systems meet warranty claims, new research finds It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of usable capacity per year on average, meaning good news for the industry as most warranties in the market can be met with the implementation of capacity reserves.

Battery developers race for Dutch grid access as TenneT unlocks 9 GW capacity Dutch transmission system operator (TSO) TenneT has unlocked over 9 GW of high-voltage grid capacity by introducing flexible contracts for off-peak hours, prompting a surge of interest from battery energy storage developers eager to secure grid access. While these contracts offer notable advantages, Aurora Energy Research says that battery storage projects continue to face challenges due to grid fees, which remain significantly higher than in other European markets.

India set to add 30 GW of storage by 2027, outpacing demand forecast India is projected to add 30 GW of new energy storage capacity by June 2027 through standalone and firm and dispatchable renewable energy (FDRE) projects, according to a recent report by SBI Capital Markets (SBICAPS). This could potentially push total capacity to 36 GW against 24 GW of estimated demand.
