Document Description
The proposed Discovery Solar PV and Storage Project is a photovoltaic (PV) solar facility with associated infrastructure necessary to generate up to 1,400 megawatts (MW) of renewable electrical energy with up to 8 gigawatt-hours (GWh) of energy storage capacity (approximately 1,000 MW) on an approximate 7,700 acre project site, across 473 privately owned parcels, in an unincorporated area of southeastern Kern County.
A 13.8-acre portion of an additional parcel located adjacent to the southern portion of the project site is proposed for a temporary, off-site construction laydown yard to supplement proposed laydown areas within the Conditional Use Permit (CUP) boundaries of the solar arrays. An additional approximate 411 acres on six (6) parcels are allotted for the proposed medium-voltage (MV) transmission and access easement. PV solar panels, a power collection system, including MV lines that connect the solar facilities, inverters, a switchyard, foundations, and transformers will be installed onsite.
Associated project infrastructure includes an operations and maintenance (O&M) facility, telecommunication facilities, energy storage system(s), two onsite collector substations, and temporary laydown yards. The proposed project also includes a generation-tie (gen-tie) line to connect the project to the existing Windhub Substation.
Implementation of the project as proposed includes the following land use entitlement requests:
