The managing director of London-based energy infrastructure company Statera has told pv magazine a clean energy grid in the U.K. will require as much flexible gas plant capacity as battery storage. The importance of energy storage in providing back-up grid power was demonstrated during an extensive blackout in the U.K. this month when 100 MW of battery capacity kicked in within 0.1 seconds to help keep the lights on. The battery capacity, operated by flexible power infrastructure business Statera, provided “100% of our performance to mitigate the effects” of the power outage, managing director Tom Vernon told pv magazine. Despite the tip-top performance of Statera’s utility scale battery capacity, however, Vernon said the ambition of a carbon-neutral U.K. by 2050 will prove impossible without extensive deployment of flexible gas back-up generation facilities. Others take the view, supported by numerous studies, that fossil fuel generation is not required at all in a 100% renewable energy system or to achieve a carbon neutral energy balance.
