Present Land Use
Planned Community District/ Planned Community .The project site is utilized by the current owner, Saddleback Church, for ancillary activities and is adjacent to the Saddleback Church Rancho Capistrano to the north, mostly open space to the south, Oso Creek to the south and east, Metrolink Railroad and Interstate-5 to the east, and open space and residences outside of the city limits to the west.
Document Description
The project is a proposed battery energy storage system (BESS) that would be capable of storing up to 250 megawatts (MW) of electricity for four hours (up-to 1,000 MW hours). The project would be composed of lithium-iron phosphate batteries (Tesla Megapack 2XL is proposed), inverters, medium-voltage transformers, a switchyard, a collector substation, and other associated equipment to interconnect into the existing SDG&E Trabuco to Capistrano 138-kV transmission line located approximately 500 feet from the project site and approximately 90 feet from the project property. The loop-in transmission line will be supported by up to 5 pole structures which will be sited to fully avoid Oso Creek. These poles consist of two poles on the Project site within the SDG&E switchyard, west of Oso Creek, and three pole on the east side of Oso Creek (two of which will be replacing existing poles); only one pole on the east side of Oso Creek will be new). Electric energy would be transferred from the existing power grid to the project batteries for storage and from the project batteries to the power grid when additional electricity is needed. No off-site transmission upgrades are required for the full capacity of this project, and an interconnection agreement with SDG&E and the California Independent System Operator has been implemented.
