Document Description
Plot Plan No. PLN 22-0154 proposes the re-development of the Inland Empire Energy Center (IEEC) generation plant, which has been decommissioned since 2020. Some of the existing infrastructure is proposed to remain, such as the switchyard, control room, warehouse, storm water drainage system, etc. For this redevelopment, the Applicant is proposing a battery energy storage system, which will use lithium-ion, flow battery, or other battery technology to store electrical energy from the grid to be discharged later when customer demand is high. The project’s capacity would not exceed the interconnection capacity which is presently 680 MW. The project includes an existing administrative maintenance building, water treatment building, and water tank and proposes (new) 323,030 sq. ft. of proposed battery energy storage system equipment enclosures, 19,383 sq. ft. of generator set-up transformers (GSUs) and switchgear, 1,214 sq. ft. of control enclosures, and 90 sq. ft. of accessory use and storage. The individual enclosures are proposed to be 8’2” high by 42’3” long by 11’5” wide. The project may be constructed in phases or all at once depending on when full capability is needed. The project will interconnect with the grid at the Southern California Edison’s Valley Substation using the facilities already in place at the decommissioned IEEC. No additional transmission facilities will be needed. The project proposes to repurpose the former IEEC’s operations buildings as well as many of the existing interconnections for water, sewer, and retail electricity service. The project site proposed to include 47 parking spaces including 2 accessible spaces. Conditional Use Permit No. PLN 22-0155 proposes to allow for the utility-scale battery energy storage system use.
