Vertically-integrated solar PV company Canadian Solar is co-developing 1.5GW of battery storage projects in the UK, extending a partnership with developer Windel Energy after the pair recently committed to developing 1.4GWp of solar in the country.

The two have signed a project agreement for the 1.5GW/3GWh pipeline, which will see Windel deliver the early-stage BESS projects under development through to ready-to-build status with Canadian Solar providing funding and support.

This is a very similar arrangement to the pair’s 1.4GWp UK solar pipeline, which also saw Windel deliver the early-stage projects to ready-to-build status, while Canadian provided funding, support and procurement of power purchase agreements (PPAs). The potential for these sites to be co-located with battery storage was also explored by Windel.

Canadian Solar has also developed battery storage sites such as the 300MWac Slate solar PV plant with 140MW/561MWh battery storage located in California, US, and the 75MW/300MWh Mustang BESS retrofit of an existing 100MWac solar PV power plant. These were developed through its US subsidiary Recurrent Energy, with both having been sold to Goldman Sachs Renewable Power.

“Windel’s decision to partner with Canadian Solar was not solely down to the current great working relationship, but also to the fact that Canadian Solar have developed and supply their own BESS integrated solutions, which simply made them the perfect partner,” said Gary Toomey, managing director of Windel Energy.
