    The United States (US) Department of Energy (DOE) is proposing to issue a loan guarantee to Sempra Generation (Sempra) to develop the Mesquite Solar Energy project, a nominal 400-megawatt (MW) solar energy generating facility consisting of a solar field of ground-mounted photovoltaic (PV) panels, an electrical collection system that converts generated power from direct current to alternating current, a substation, and a generation-tie (gen-tie) power line to deliver the generated electricity from the project site to an existing off-site electrical switchyard. The facility would generate an estimated 889,665 megawatt-hours (MWh) of electricity per year.
