The cost to build new wind projects has decreased significantly over the last several years. This is largely the result of continued technological advancements that improve turbine efficiency. This project would add 150 megawatts of wind energy, enough to power an additional 70,000 homes. The company's Wisconsin customers already benefit from low-cost wind through Alliant Energy's ownership in three wind farms. Alliant Energy has entered into a contract with Invenergy to purchase the project after development is complete. Invenergy is the largest privately held renewable energy company in North America. A decision from the PSCW is expected in early 2019. If approved, construction is expected to start in summer 2019. This project will not affect the company's recently announced plans to keep base rates flat through 2020.
