Xcel Energy and SunPower signed a PPA to build a 50-MW solar power plant in Colorado's San Luis Valley. Construction of the solar power plant is contingent on the project securing all required permits, interconnection rights and financing. SunPower expects to start construction in 2015, and to achieve full commercial operation by the end of 2016. At the 320-acre site, SunPower will design and build a SunPower Oasis Power Plant system. Oasis is a fully integrated, modular solar power block that is engineered to rapidly and cost-effectively deploy utility-scale solar projects while optimizing land use.
