Dollyman’s 100MW Battery Storage
We were employed to carry out the transformation of the site at Dollyman’s Farm into a 100MW battery storage facility for Statera Energy.
The project involved the installation of 60 power converter system (PCS) units, 60 battery energy storage system (BESS) units and an ICP compound comprising of a 132KVA transformer, control room, ancillary infrastructure and connections.
Technical Challenge
We worked collaboratively with the client in order to produce the necessary methodology to support the designs of the new technology and meet the strict programme milestones.

Site constraints that were mitigated throughout the project included:
• High voltage overhead cables
• Strict deadlines and key project milestones
• High water levels
• Risk of flooding due to weather conditions
• Local Authority/Environment Agency conditions

The full scope of works included:

• Extensive service and drainage installation
• PCS and BESS infrastructure – footings, drip trays, interceptors
• Co-ordination and management of lifting operations involved with placing the PCS and BESS units
• Co-ordination and management of local authority and traffic management permits
• S278 works
• Culvert installation
• New roads
• Reinforced concrete works for control rooms and transformer bunds
• Creation of site attenuation pond and headwalls

Infrastructure, Earthworks, S278 Works
The project reflects our strategic objective to support sustainability and work towards a low carbon future.

Working with innovative developers and independent connection providers to offer all civil engineering requirements for energy storage and distribution projects.
