11MW/22MWh Broadditch BESS

The Broadditch Battery Energy Storage System (BESS) is an 11 MW/22MWh project located in Kent, UK, developed by Harmony Energy Income Trust plc (HEIT). Energised in March 2023, it utilises six Tesla's two-hour Megapack 2XL batteries and is managed through Tesla's AutoBidder software for autonomous trading and operational control. This system enhances grid stability by storing excess energy during low demand and releasing it during peak periods, supporting the UK's renewable energy integration efforts.

Sector	Battery Energy Storage System
Developer	Harmony Energy Income Trust plc (HEIT)
Project	Broadditch 11MW/22MWh
Location	Kent
Scope of Work	Three 2.8MVA 33kV/480-480V Wilson T2 Ecotrans® Transformers 100kVA 33kV/433 Auxiliary Transformer

This 22MWh battery energy storage system features the first energised Tesla Megapack 2XL outside North America. We supplied the site with three 4200kVA 33kV/480-480V Wilson T2 Ecotrans® Transformers and one 100kVA 33kV/433V Auxiliary Transformer. The MV transformers feature dual LV winding, allowing each transformer to connect to two Tesla megapacks while enhancing resilience.
