CalSun Solar Project

Document Description: CalSun is a solar pv energy generation and storage project, consisting project, consisting of single axis tracking solar pv panel arrays capable of producing approx 20 MW of electricity, and a battery system able to store approx 20 MW of energy. The CalSun site is in the northeastern corner of Alameda County, CA on a single 112.8 parcel. The site is an irregular polygon bordered on the northeast by the Byron-Bethany Road (County Road J4, also known as Byron-Bethany Highway), and on the west by Mountain House Rd. The Contra Costa County line also intersects with the northern tip of the project site. The portion of the site to be developed for the solar generation and energy storage facility is 89.1 acres in size. The project would not require a new transmission line but would connect to the grid adjacent to the property.
