Siemens Gamesa supplying wind turbines for MidAmerican in Iowa

Iowa-based utility MidAmerican Energy has selected Siemens Gamesa to provide wind turbines for its Southern Hills Expansion project in that state.

Siemens Gamesa will supply 21 of its SG 4.5-145 wind turbines for the Iowa wind farm. The deal includes a three-plus-year service and maintenance agreement.

The SG 4.5-145 turbines have a output between 4.2 to 4.8 MW each. Overall, Siemens Gamesa has installed more than 1,100 turbine units with a capacity of nearly 3 GW for MidAmerican in Iowa.

“We are once again proud to have been awarded a project by MidAmerican Energy Company, strengthening our long-standing relationship with them,” said José Antonio Miranda, CEO of Onshore Americas at Siemens Gamesa Renewable Energy. “We have had great success with the SG 4.5-145 wind turbine, with over 1.4 GW sold in the U.S., Canada and Mexico, and are excited to continue growing that number.”

The 95-MW Southern Hills Expansion is one of several wind farms planned or operated by MidAmerican in Iowa. Overall, the utility has invested more than $10 billion in wind projects across the state.

Iowa ranks second nationally with about 8.5 GW of installed wind power capacity, according to 2018 figures.

Siemens Gamesa has installed more than 10,000 wind turbines in the U.S. totalling about 20 GW of installed capacity.
