London, 18 July 2022

Fotowatio Renewable Ventures (FRV), part of Abdul Latif Jameel Energy and one of the world’s leading renewable energy companies, and UK developer Harmony Energy, have announced the initial construction works of Clay Tye, UK’s largest battery storage development project in their mission to contribute to the decarbonization of Britain’s energy grid.

The Clay Tye site is located in Essex and will have a total power of 99MW / 198MWh, making it the biggest project of its kind under construction in the UK. Clay Tye follows the successful completion of FRV and Harmony Energy’s West-Sussex based battery storage facility, Contego, which has a capacity of 34 MW / 68 MWh. It also follows the completion of FRV’s Dorset-based Holes Bay battery energy storage project, which has a capacity of 7.5 MW / 15 MWh. The project reflects FRV’s long-term investment plan to develop energy storage projects globally in countries like Australia, Mexico, Chile and Spain.

Clay Tye, uses 52 Tesla Megapack lithium-ion batteries, together with Tesla’s Autobidder AI software for energy capacity exchange and efficient project management. The Megapack batteries have a capacity of 198 MWh and are connected to UK Power Networks distribution network, providing the capability to store energy from renewable sources and afford peak-time flexibility to the UK National Grid as part of the UK’s continuing shift away from fossil fuels.

Both FRV and Harmony Energy expect the BESS plant to be finished and energizing during the first quarter of 2023.

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.

Felipe Hernández

FRV Managing Director of Engineering and FRV-X

This is another significant milestone in our continued growth and we’re pleased to be working alongside FRV once again. Clay Tye has taken 6 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.

Peter Kavanagh

Harmony Energy CEO

We are always looking for opportunities to spearhead the move to a more sustainable future. Today, we are collaborating with Harmony Energy to commence the construction of Clay Tye, which highlights our commitment to tackling climate change in a tangible and sustainable way. The energy transition has always been a core priority for us, and we are working hand-in-hand with the right partners to develop an energy system that is more sustainable, secure and affordable.
