UK investment management group Downing LLP has announced its first utility-scale battery storage site in the country, a 50MW/53MWh project in Nursling, Southampton on England’s southern coast.

The group, which invests in diverse assets with a claimed focus on social and sustainable investing including the renewable energy sector, has selected its co-funding partner as well as having entered into agreements for the supply of the storage solution, the optimisation of the asset and the route to market and trading arrangements.

Grid connection work is already largely complete at the site, which is managed by UK-based construction company Arun Construction Services. It will work as the principal contractor through the installation of the asset, which is expected to connect to the grid and begin operation in August 2021.

The battery storage solution will be provided by South Korean supplier Hyosung Heavy Industries corporation in what will be its first transmission-connected battery project in the UK.
