Building a SOLV Energy First
Chirreon is a 13-megawatt (MW) solar PV facility and 15,000-kilowatt battery energy storage system (BESS) project in Catalina, Arizona. This project is SOLV Energy's first self-perform solar-plus-storage facility. Chirreon was developed by Torch Clean Energy and is part of Trico Electric Cooperative's generation portfolio, which serves more than 46,000 members in rural areas surrounding the city of Tucson.
Chirreon is the first project to include BESS in Trico's growing portfolio of renewable generation resources, now totaling nearly 50,000 kilowatts of capacity. Incorporating solar-plus-storage facilities, like Chirreon, aligns with Trico's goal to serve communities and their customers with flexible, reliable and affordable energy options, while reducing reliance on fossil fuels and non-renewable resources. In 2022, 26% of energy supplied to Trico customers was generated by renewable facilities, up from just 1% in 2010.
The 13 MW PV project will produce electricity for up to 3,000 households annually, while the 15,000 kW batteries can power 4,000 homes for two hours. The project, located on 99 acres, utilized domestically sourced steel trackers, over 29,000 solar modules, four inverters and 12 batteries. As part of Trico's community solar portfolio, the benefits of the clean energy generated by Chirreon are shared by all Trico members.
