Badger Mountain

Aurora Solar, LLC (Applicant), a wholly owned subsidiary of Avangrid Renewables, LLC, proposes to construct and operate the Badger Mountain Solar Energy Project (Project). The Project is a 200-megawatt (MW) solar photovoltaic (PV) generation facility with an optional 200-MW battery energy storage system (BESS) located in unincorporated Douglas County (County), Washington. The Project is generally located approximately 3.5 miles east of the East Wenatchee city limit boundary and south of Badger Mountain Road.

The Project will use solar modules configured in a solar array to convert energy from the sun into electric power. The solar modules are mounted on a tracker system supported by steel posts and will be connected in a series to form rows, which are in turn connected to form the solar array. The solar array will consist of the solar modules, tracker system, posts, cabling, inverters, transformers, and electrical collector lines. The solar array inverters are paired with medium voltage step-up transformers used to convert the generated electricity from direct current (DC) to alternating current (AC) and increase the voltage for distribution.

The Project’s Commercial Operations Date (COD) is planned for fourth quarter (Q4) 2024 and Project construction is anticipated to begin in Q1 2023.
