The 99MW/198 megawatt-hour Clay Tye energy storage project in Essex, southeast England, has begun early construction works according to UK developer Harmony Energy and Fotowatio Renewable Ventures (FRV).
52 Tesla megapack lithium-ion batteries will be included in Clay Tye, along with Tesla’s Autobidder AI software for managing projects and exchanging energy capacity.
With the potential to store energy from renewable sources and peak-time flexibility, the batteries will be connected to UK Power Networks’ distribution network.
The project is anticipated to be built and powered within the first quarter of 2023. Once operational, it will be the largest battery energy storage system (BESS) in the UK.
Felipe Hernandez, FRV managing director, said “Clay Tye is going to be a significant milestone in our growth objective in the UK energy storage market.
“This BESS strengthens the long-term sustainability of our business model and our leadership position in the market.
“In this way, we are continuing the path for the future FRV’s assets in the country, which are in the commercial operation, construction and development phase.”
Peter Kavanagh, Harmony Energy chief executive, said “This is another significant milestone in our continued growth and we’re pleased to be working alongside FRV once again.
“Clay Tye has taken six years to reach this stage. It is one of the largest projects of its kind in the UK and will contribute to future energy security whilst supporting decarbonisation of the grid.”
