Mega-battery plant to come online in Sheffield

Facility run by E.ON, to be followed by many more, will help UK grid cope with fast-growing amount of renewable energy

Britain's switch to greener energy will take another significant step forward this week with the opening of an industrial-scale battery site in Sheffield.

E.ON said the facility, which is next to an existing power plant and has the equivalent capacity of half a million phone batteries, marked a milestone in its efforts to develop storage for electricity from windfarms, nuclear reactors and gas power stations.
