Covina Reliability Battery Energy Storage System Project

The Project consists of the construction, operation, and decommissioning of a 110-megawatt (MW) battery energy storage system (BESS). The Project is designed to charge or discharge electricity to and from the grid via a BESS with associated on-site support components consisting of inverters, collector lines, fencing, access roads, supervisory control, a Supervisory Control and Data Acquisition (SCADA) system, and other ancillary facilities or equipment. The Project would include construction of an on-site Project substation on the west site, which will allow interconnection to the existing and adjacent Southern California Edison (SCE) Cortez Substation via an overhead generation transmission (gen-tie) line. To facilitate operation of the Project, SCE would make various improvements to the Cortez Substation. SCE's improvements would occur within areas previously disturbed and occupied by existing electrical facilities within and adjacent to the substation. The Project is anticipated to be built over an approximately 14-month period from the onset of site preparation activities through testing and commissioning of the facility. Once constructed, the Project would operate 7 days per week, 365 days per year. The BESS would be recycled at the expiration of the Project's life (30 years). Development of the Project would require the following discretionary permits and approvals from the City: a Site Plan Review, Conditional Use Permit, adoption of the Mitigated Negative Declaration, and ministerial approvals and permits necessary to execute the Project, including, but not limited to; grading permits, building permits, and construction encroachment permits.
