Taking a rigorous approach to inspection is crucial across the energy storage supply chain. Chi Zhang and George Touloupas, of Clean Energy Associates (CEA), explore common manufacturing defects in battery energy storage systems (BESS’) and how quality-assurance regimes can detect them.

Nidec has deployed a 12 MW/24MWh storage system for French grid operator RTE. The battery – part of a 72 MWh project to prevent grid congestion in peak demand periods – is in an area with abundant renewables, including wind.

With cumulative capacity reaching 9.43 GW at the end of December, France saw electricity generation from solar increase 7.8% last year.

RTE and GRTgaz have created a common databank to analyze how power production from renewables can be better integrated into France’s electricity system.
