Battery energy storage system developers have written an open letter arguing Ofgem’s long-duration energy storage support scheme introduces biases against BESS.
Gresham House, the largest owner of battery energy storage system (BESS) assets in the UK, has said it sees tolling deals like the one agreed with Octopus being possible “across the optimiser market”.
Octopus Energy has signed a two-year fixed-price tolling agreement with Gresham House Energy Storage Fund for 500MW of its battery assets, bringing the utility’s virtual power plant (VPP) portfolio to over 1.5GW.
Statkraft has signed a Power Purchase Agreement (PPA) with Gresham House and a Corporate PPA with Workspace for the 20MW Beavor Grange Solar Farm in Devon.
Battery energy storage fund Gresham House has released annual accounts for the first half of 2023, showing lower H1 2023 revenues and a drop in share value.
