The UK’s second subsidy-free solar farm, and the first by a local authority using battery storage, has been completed by West Sussex County Council in a project that ticked “every box” and will generate significant income over the next 25 years.
Battery storage technology costs will have to fall by a further 30% before projects in the UK are feasible without lucrative frequency response revenues, a leading investor has said.
The number of installed stationary battery energy storage systems (BESS) is growing significantly. According to recent estimates, today’s annual global market volume of about US$1 billion is expected to increase more than twentyfold in less than 10 years, reaching a staggering US$20–25billion by 2024. Florian Mayr of Apricum Consulting looks at this growth in the context of specific use cases for storage in two of its most advanced regional markets, the US and Germany.
Reports that a grid operator in France has found battery-based energy storage “too costly” to be used to integrate renewable energy have been criticised by a spokesman for energy storage developer Younicos.
