The City of Tucson, Ariz., Tucson Water Department, Trico Electric Cooperative and SunPower Corp. have dedicated a 1 MW ground-mounted solar power system, which doubles the solar power system capacity hosted by the city.
The system was designed and built by SunPower on city-owned, formerly agricultural land located within Tucson Water Department's underground water storage and recovery facility, approximately 20 miles west of downtown Tucson. The city financed the system through a power purchase agreement with SunPower.
Trico Electric Cooperative will purchase the renewable energy credits associated with the system. The city's cost for the energy will be competitive with its current bulk retail rate, with no initial capital investment, according to the project partners.
