E.ON wins ‘milestone’ UK battery storage deal

E.ON has won a contract with UK transmission system operator National Grid to supply a 10 MW battery energy storage system.

The deal comes in the wake of a tender from National Grid to find a new service to handle the fluctuations in generation from an increasing number of wind and solar installations on the grid.EON wins UK battery energy storage deal

E.ON’s system will feature a 10 MW lithium-ion battery which will be the size of four shipping containers and have an equivalent power of roughly 100 family cars.

It will be built at E.ON’s Blackburn Meadows Biomass CHP and District Heating site near Sheffield and the system is planned to be operational by the start of 2018.

E.ON board member Karsten Wildberger said: “We are delighted to build one of the first commercial battery systems in the UK. This is a milestone for E.ON in the new energy world and an important recognition of the enormous potential battery solutions bear.

“We continue to work on new storage solutions going beyond security of supply, for example combining applications to increase self-consumption, shave peak-loads or to improve service for our industrial and commercial customers.”

E.ON said that at times of either an oversupply or an undersupply, its battery system will respond “within one second, absorbing or discharging power into the local distribution network to which the battery is connected and thus maintaining the system frequency at a safe level”.
