Wave Hub Battery – one of Cornwall’s largest batteries.

Located at the Wave Hub substation is a large battery with supporting Smart Grid Infrastructure.

An upgrade of battery storage capacity from 1.0MW.Hr to 1.5MW.Hr is currently underway and is expected to be completed by Autumn 2020. The site also has planning permission for battery storage capacity to be increased further to 5MW.

  • This will be one of Cornwall’s largest batteries once complete.
  • The battery will be connected to Centrica’s Local Energy Market to provide energy resilience to the Wave Hub site and the local grid.
  • The battery can be used in conjunction with energy generation assets such as floating offshore wind turbines to optimize the export of power to the local grid.

The multi award-winning Cornwall Local Energy Market offers a glimpse into the future of a truly decentralised energy landscape with hundreds of thousands of homes and businesses playing their part in regional energy markets. It goes further than any previous project in exploring how decentralised flexible assets can work together in an efficient local energy system that meets the needs of generators, customers and networks alike – reducing strain on the grid at peak times and maximising the productivity of renewable energy generation.

“Ultimately the Cornwall Local Energy Market project is about developing the integrated technology solutions needed for a fully decarbonised electricity system. We are working with businesses across the county to deliver solutions which help them to both decarbonise and benefit from the opportunities of a changing energy market.”

Charles Cameron, Group Technology and Engineering Director, Centrica

“We’re delighted with this project, not only because of the use for Wave Hub’s grid connection, but also because of the opportunity to begin exploring how flexibility markets, such as the Cornwall LEM, might integrate with the first, floating offshore wind turbines at the Wave Hub site and, in the longer term, large floating offshore wind projects that we are seeking to develop in the Celtic Sea.”
