Document Description
The County of Colusa, as the Lead Agency, has prepared a Draft Environmental Impact Report (DEIR) for the proposed Use Permit (UP) and Williamson Act contract cancellation to construct, operate, maintain, and decommission a photovoltaic (PV) electricity generating facility, with a battery energy storage system (BESS) and associated facilities and infrastructure, commonly known as the Janus Solar Project (Project). The Project consists of three major components: a solar energy generating facility, the battery energy storage system (BESS), and the generation tie-line. The solar facility would include arrays of solar PV modules (or panels) and support structures, direct current (DC) electricity to alternating current (AC) electricity power inverters and transformers or power conditioning stations, and an on-site substation. The Project would include approximately 196,000 solar PV modules in multiple solar arrays interconnected to form a utility-scale PV system. Other solar facility components would include a project substation, access roads, perimeter fences, telecommunications infrastructure, a meteorological data collection system, signage, lighting, stormwater facilities, and an operations and maintenance building. The BESS is expected to be located adjacent to the aforementioned substation. Batteries would be contained within metal enclosures. The combined footprint for the BESS would be approximately 5 acres. Key components of the BESS include batteries and battery storage system enclosures and controllers, converters, inverters, and transformers. Sealed battery modules would be installed in self-supporting racks electrically connected either in series or parallel to each other. The BESS enclosures would house the batteries as well as the battery storage system controllers. The BESS enclosures would also house required heating, ventilation, and air conditioning (HVAC) and fire protection systems. The on-site substation would connect to the existing Cortina Substation via an approximately 3-mile-long, 60 kV gen-tie line strung on approximately 59 new poles of up to 80 feet in height. The gen-tie line also would include fiber optic line for communications.
