Bishop Ranch office park will be 85% solar powered by the end of 2023 thanks to a solar installation Sunset Development says is likely the largest of its kind nationally.

The San Ramon-based developer plans to install 17 megawatts of solar panels and an additional 7 megawatts of storage at the business park through the end of 2023, according to Harout Hagopian, senior vice president and general manager. The project is the largest solar installation by “a multitenant landlord in a specific geographic location,” a spokesperson for Sunset Development said.

The installation will generate approximately 25 million kilowatt hours annually — enough to power around 2,347 American homes for an entire year, according to data from the U.S. Energy Information Administration. It will utilize Tesla powerwalls for energy storage.
