Document Description
Request to establish a photovoltaic (PV) solar energy farm creating an aggregate peak power capacity of 40 megawatts (MW) of electricity on a 314± acre parcel in the A- 2-40 (General Agriculture) zoning district. The project will consist of a collector substation enclosed within a 16,500 square-foot compound, a battery energy storage system (BESS) with a 40 megawatt (MW) backup capacity for the electric grid, an underground 34.5kV electrical collector system and inverters, a generation tie-line route which will run north and interconnect to the existing Sullivan Solar Project (UP WA-CAN PLN2015-0081) generation tie-line, and an operations & maintenance building. Construction will occur over 7-10 months with 3-4 temporary staging areas used for parking and material storage over the course of the construction process. The applicant anticipates up to 4-5 employees on a maximum shift, and one on a minimum shift during operation, manning the maintenance & operation building during daylight hours. The application materials indicate that on-site well water will be utilized during construction as needed, and water sourced from the Del Puerto Water District will be trucked in to serve the site during operation. No method of wastewater management has been indicated; however, the project will be conditioned requiring the provision of restrooms for the on-site employees. The facility will be surrounded by a seven-foot-tall perimeter chain-link fence and will take access onto a privately-maintained portion of Sullivan Road via two gated driveways. The property is enrolled in an active Williamson Act Contract; however, because this request is for a Tier 3 Use Permit which prohibits the project site from being enrolled in a contract, a Williamson Act Cancellation for the 300± acres is included as part of this request. Under the proposed lease agreement and will operate for approximately 35 years; after which, the project site will be decommissioned and returned to agricultural use.
