Developer and IPP Elevate Renewables will deploy a grid-forming BESS at a fossil fuel peaker plant in Connecticut, US, with US$27.5 million from the Department of Energy (DOE).

Siemens Energy will provide the technology for a project in Ireland combining a synchronous condenser and a battery energy storage system (BESS) of 160MWh.

Taking the UK’s transmission system and the circumstances which led to a dramatic blackout as a direct example, Javier Cavada and Gary Preece of liquid air energy storage (LAES) systems company Highview Power look at how such events could be avoided, cost-effectively and with lesser environmental consequences.

Batteries are increasingly widely used in grid balancing, but there are many more applications where a battery can play an important role. With electric grids requiring periodic maintenance, batteries can stand in for the grid during downtime in order to reduce the impact on industry and households, writes Dieter Castelein.
