Project Overview
Battery energy storage is critical in supplying affordable, clean power, whilst also enhancing the UK’s grid reliability. The Hams Hall site has a 350 MW transmission network connection capable of providing energy to approximately 120,000 homes. The approved design allows for deployment of more than 1,750 MWh of battery storage. The Hams Hall project is expected to provide a broad range of services to support the UK electricity system including potentially longer duration services, with scope for more than five hours duration.
North Warwickshire Borough Council considered that the need for large-scale battery storage in the Midlands to support National Grid requirements, combined with the limited site opportunities for a development of this size and nature, meant the proposal met the very special circumstances necessary to support development in the green belt.
Key Numbers
The Hams Hall BESS (in co-operation with Energy.Io), located near Birmingham, features the design and construction of the following:
- 400MW 1000MWh battery storage unit.
- 124 blocks of ESS units.
- New 400V Bay as connection point within NGET compound.
- Construction of an approx. 40,000m2 platform using cut/fill ground improvement earthworks.
- Civil and Electrical BoP Design and Build.
- Key structures include the 400/33KV substation building, two Switchgear buildings and two control buildings – alongside their associated foundations.
