One of the projects, dubbed Keith, a 39MW/200MWh battery storage facility, is one of the longest-duration BESS projects to reach financial close in the UK to date. The project is expected to help manage the heavily constrained B4 transmission boundary in Scotland, which is a key transmission constraint area across central Scotland.
The battery system for Keith will be supplied by Chinese energy storage provider Sungrow, with balance of plant works delivered by Scottish contractor RJ McLeod. Financing has been secured from ING Group and Rabobank.
The project is scheduled to begin operations in 2027.
Meanwhile, Hartmoor is a larger 200MW/800MWh project that will provide additional flexibility in the Northeast of England as offshore wind capacity expands and existing generation assets face retirement.
The project is expected to support the integration of the Dogger Bank Wind Farm development and provide grid support as EDF Energy’s Hartlepool nuclear power station approaches decommissioning.
