UK energy industry regulator Ofgem said it is minded to approve the introduction of a financial commitment for BESS in an attempt to reduce the oversupply of the projects awaiting a grid connection.

Compressed air energy storage (CAES) holds much promise for large-scale, LDES, but has struggled to get off the ground outside of China.

A flurry of project completions, financings and supplier deals for large-scale BESS across the Central and Eastern Europe (CEE) region, from Greenvolt, Renovatio & CATL, Eurowind, Renalfa, MOL Group, Tavion, MetaWealth and Enexus & Longi. 

Nearly 21GWh of grid-scale BESS came online globally last month, of which around a fifth was in Saudi Arabia while the majority was in China. 

RWE has taken a final investment decision (FID) on 400MW/1.1GWh BESS in the Netherlands with construction to start in due course, while Giga Storage has started building its 2.8GWh Green Turtle project in Belgium.

What is repetitive re-trading (RTT) by BESS in the UK, and what is NESO looking to do about it?  

Covenergo and Delta Capacity have begun construction on AKKU One, a standalone 125MW/300MWh battery energy storage system (BESS) in Lapinlahti, Finland, with commissioning targeted for the fourth quarter of 2027.

Poland’s grid-scale storage market has reached an impressive scale in the last few years, helped by the capacity market and various government schemes, but numerous challenges now need to be overcome.

System integrator Fluence and lithium-ion battery OEM Eve Energy have struck a massive 206GWh battery supply framework agreement for 2027-31, one of the largest deals of its kind ever announced.

Existing assets can provide crucial benchmarks in sizing and other crucial battery storage design decisions, writes Ashutosh Vats, head of BESS business development at 3E.
