34MW/68MWh Contego BESS

Located near Burgess Hill in West Sussex, Contego has twenty-eight Tesla Megapack lithium-ion batteries, making up 34MW of battery energy storage capacity. We have supplied the site with fourteen 2.8MVA Wilson e1 Ecotrans® Distribution Transformers and one spare, with a voltage ratio of 33kV/505V. These transformers are integral to the operation of the battery storage system, facilitating efficient energy conversion and distribution.

Harmony Energy and Fotowatio Renewable Ventures (FRV) developed the project. The site is managed through Tesla’s Autobidder AI software for real-time trading and control and is connected to UK Power Network’s (UKPN) distribution network. Contego BESS provides the capability to store energy from renewable sources to be used during peak demand hours. This also increases the flexibility of the UK National Grid while contributing to the country’s mission to move away from fossil fuels.
