We hear from industry sources about the upcoming Real-Time Co-Optimization Plus Batteries (RTC+B) market changes in ERCOT, Texas, and why they represent a fundamental shift in how BESS will operate in one of the world’s largest and most lucrative energy storage markets.

A panel of owner-operators, optimisers and developers discussed the evolving dynamics of the ERCOT, Texas market at last month’s Energy Storage Summit USA 2025 in Dallas.

Energy storage owner-operator BW ESS and Zelos Energy Developments have announced a 1.5GW pipeline of BESS projects in Germany, aiming for ready-to-build (RTB) status over the next two years. 

Integration of data analytics and asset revenue data will give battery storage operators an edge in the ERCOT market, TWAICE claims.

BloombergNEF (BNEF) has found that utility-scale BESS uptake in Australia could increase eightfold to 18GW in 2035, up from 2.3GW in 2024.

Battery storage can turn record-high instances of negative spot pricing in Australia’s National Electricity Market (NEM) into investment opportunities.

On day one of the Energy Storage Summit Australia 2025, the audience heard that although 2 to 4-hour duration battery energy storage systems (BESS) are favourable, longer durations are starting to challenge this.

Energy software and consulting group Ascend Analytics CEO Gary Dorris discusses changes to ancillary services in the Electric Reliability Council of Texas (ERCOT) market and what asset optimisers need to do to stay ahead of the curve.

We continue our look back at 2024 with a selection of our sponsored webinars broadcast throughout the year.

Vanadium flow batteries could be a workable alternative to lithium-ion for a growing number of grid-scale energy storage use cases, say Matt Harper and Joe Worthington from Invinity Energy Systems.
