Canadian Solar has signed long-term operations and maintenance (O&M) agreements with two solar PV plus battery storage projects in the US.

The agreements cover the full Slate project, which is a 300MW solar plant designed with a 140MW/561 megawatt-hour (MWh) battery energy storage system as well as the 75MW/300MWh battery retrofitted at the 100MW Mustang solar project.

The Slate and Mustang projects were both developed by Canadian Solar's subsidiary Recurrent Energy and are now owned by Goldman Sachs.

Both projects are located in Kings County, California.

Under the long-term agreements, Canadian Solar will be responsible for various O&M obligations across both projects, including plant monitoring, NERC registration, performance management and preventative and corrective maintenance.

Canadian Solar services will help to increase site availability, minimise downtime and maximise the value of the projects.

Canadian Solar now has a global O&M portfolio of nearly 4GW of solar and 860MWh of storage projects under contract across nine countries, of which 2.3GWp of solar projects are in operation.

These projects include both Canadian Solar as well as third-party developed projects.

The company is targeting to reach 11GW of operational solar projects by 2025, expanding its share of stable income.

Canadian Solar CEO Shawn Qu said: “As we expand our market leadership position from solar energy into battery storage project development and systems integration, offering operations and maintenance services in battery storage is a natural extension of Canadian Solar's value proposition.

“We will continue to add value to our customers by providing the best quality service, maximise production of clean renewable energy and enhance the value of solar and battery storage assets through our O&M services.

“We are delighted to be selected by Goldman Sachs to provide O&M services to both the Mustang and Slate solar and storage projects and look forward to the long-term partnership."
