EDF and Wärtsilä strike 100MW battery deal


EDF has ordered 100MW of storage from Wärtsilä and will deploy the batteries at two UK projects, the 50MW Oxford ‘superhub’ and at a site in Sittingbourne, north Kent.

The sites are both projects developed by Pivot Power, recently acquired by EDF.

The Oxford superhub scheme was originally set to include 48MW battery and 2MW of flow storage. It is now progressing with 50MW of lithium ion, though flow storage provider Red T said it “will still provide the flow battery element of the project”.

The Oxford storage facility will be connected at transmission level at Cowley substation to underpin a network of EV chargers via a 10km private wire around the city.

Some 300 heat pumps are set to be installed as part of the project, which, along with the battery and EVs, will be smartly controlled to enable flexibility trading.

Habitat Energy will trade the flexibility, largely on the wholesale markets. Kensa Contracting will provide the ground source heat pumps.

The storage, private wire and EV chargers are slated to be in place by the end of this year, with the heat pumps installed by 2021, when the Renewable Heat Incentive closes.

The 50MW Sittingbourne project is also expected to be operational by the year end.
