PLNP2024-00021 Arboleda Battery Energy Storage System Project

The project site would be accessed from HighThe proposed project would include an up-to 250 megawatt (MW), 4-MW-hour (MWh) BESS facility, which means that at maximum capacity, the facility can potentially deliver up to 250 MW of power over a duration of 4 hours. In addition to the battery systems, the facility would include associated accessory structures that are described further below. The project also includes a 230-kilovolt (kV) offsite, overhead generation tie (gen-tie) line, which would interconnect at the Sacramento Municipal Utility District (SMUD) Elk Grove Substation. The project would be designed to charge or discharge up to 250 MW of electricity over a four-hour period and would consist of lithium-ion or similar technology batteries housed in storage containers installed with heating, ventilation, and air conditioning (HVAC) or similar cooling systems and fire protection and control systems. The proposed BESS would include associated ancillary facilities consisting of an on-site project substation and control room, power conversion stations (with inverters and transformers), buried collector lines, and Conex containers for storage and offices. The project would also include other facility features including: miscellaneous maintenance equipment outdoor storage area; fencing; internal access roads; permanent noise barrier walls; drainage design features, such as detention basins; landscaping along the facility frontage; and entrance signage. The project would also include a 230-kV gen-tie line. The proposed BESS facility would include multiple self-contained, prefabricated enclosure units in a parallel configuration with spacing between each unit as required by the manufacturer. The enclosure units would contain lithium-ion, or similar technology, batteries stored on racking. Each of the enclosure units is expected to be up to 12 feet tall, up to 12 feet wide, and up to 44 feet long, depending on manufacturer. There would be no internal open space available within the enclosures for entry or occupation. Battery racking would only be accessible from the exterior of the enclosures via external doors. Each enclosure unit would have a fire rating in compliance with industry standards, including the National Fire Protection Association (NFPA) 855, Standard for the Installation of Stationary Energy Storage Systems, Underwriters Laboratories (UL) 9540, Standard for Energy Storage Systems, and as required by the Consumnes Community Services District Fire Department. Each unit would also be equipped with a cooling system for thermal management of the batteries. These systems would be automatically and continuously monitored onsite through the supervisory control and data acquisition (SCADA) system and through an off-site remote monitoring system. Energy would be transported between the on-site substation at the project site to the SMUD Elk Grove Substation through an overhead 230-kV gen-tie line.
