February 13 (Renewables Now) - US electricity and natural gas utility MidAmerican Energy Co on Monday said it has fully completed two wind farms in Iowa with a combined capacity of 338 MW.
The two facilities are the first ones brought online as part of MidAmerican’s 2,000-MW Wind XI project under which the utility will install 1,000 wind turbines across Iowa. All of the machines, with a capacity of 2 MW each, will be supplied by Denmark's Vestas Wind Systems A/S (CPH:VWS).
One of the new wind parks, called the Beaver Creek, is located in Boone and Greene counties and has a capacity of 170 MW. Meanwhile, the Prairie wind farm, totalling 168 MW, is situated in Mahaska county. Construction of the two plants, using a total of 169 turbines, was initiated last spring. Although most of the capacity was switched on last year, the final 4 MW of the total were put on stream in January, MidAmerican said.
The Beaver Creek and the Prairie wind parks are seen to generate enough electricity to meet the annual demand of over 140,000 Iowa households.
The huge Wind XI complex is expected to be fully operational in December 2019. It will enable MidAmerican, which has a 100% renewable energy objective, to meet over 90% of the energy consumption of its retail customers in Iowa by 2020. In November 2017, construction was launched on the third facility of the complex -- the 340-MW North English plant, expected to become operational at the end of 2018.
