49.5MW/99MWh Chapel Farm BESS

Energised in May 2023, the 99MWh Battery Energy Storage System near Luton is a joint venture between TagEnergy and Harmony Energy. We supplied the project with fourteen 4.2MVA Wilson T2 Ecotrans Large Distribution Transformers with 33kV HV and 480V dual LV windings and a couple of 100kV 33kV/433V Auxiliary Transformers. 

The twenty-six Tesla Megapack lithium-ion batteries are supported by Tesla’s Autobidder AI software for real-time trading and control, with operations overseen by RES, a prominent asset management company. The project plays a major role in contributing to the Net Zero transition by unlocking the full potential of renewable energy without relying on taxpayer subsidies.
