1.1-GW solar + 2,165-MWh storage project in California begins construction

Renewable energy developer and operator Terra-Gen has contracted Mortenson to build the Edwards & Sanborn solar and energy storage project in Kern County, California. The project consists of 1,118 MW solar and 2,165 MWh energy storage. It is currently the largest single Solar + storage project to reach this milestone.

“Choosing the right partner to carry out a project of this magnitude combined with cutting-edge battery expertise was paramount to Terra-Gen, and Mortenson was a natural fit,” said Brian Gorda, vice president of engineering for Terra-Gen. “Terra-Gen is excited to take the industry to a new level and build a facility that provides energy for all hours of demand.”

The Edwards & Sanborn project is located near several ongoing wind and solar projects in Kern County, California. Mortenson is the full EPC contractor for both solar and energy storage. Construction of the site will begin in the first quarter of 2021 and is expected to be completed in the fourth quarter of 2022.

More than 2.5 million modules are used for solar production at the site and more than 110,000 lithium-ion battery modules are used for energy storage.

“Edwards & Sanborn’s solar and energy storage project is transforming the industry and will redefine the impact these systems will have on our clean energy future in this challenging 2020,” said Trent Mostaert, vice president and general manager of Solar at Mortenson. “We are proud to combine our know-how in the design and construction of solar and energy storage with the development capacities of Terra-Gen in order to deliver a first-class energy system.”

At peak times, more than 700 people will be employed on site in the project.
