Siemens Gamesa has been selected by MidAmerican Energy Company for the Southern Hills Expansion wind power project, which will feature 21 SG 4.5-145 wind turbines, operating at 4.8 MW, and will be located in Iowa. This project also features the company’s premier service and maintenance agreement for three and a half years. 

The turbine model, a benchmark solution for sites with medium winds, has been designed to offer a flexible rating ranging from 4.2 to 4.8 MW, increasing its adaptability to be configured for optimal performance in each individual project, achieving maximum returns. 

“We are once again proud to have been awarded a project by MidAmerican Energy Company, strengthening our long-standing relationship with them,” stated 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 wind major has installed over 10,000 wind turbines in the U.S. totalling about 20 GW of installed capacity. In Iowa, the company reports that it has installed nearly 1,400 wind turbines for a total of almost 3.5 GW. Of that, 1,164 units for a total capacity of nearly 3 GW are with MidAmerican Energy Company, highlighting the strong collaboration of both companies.

Recently, secured its first order in India with Alfanar for the supply of 206 units of the SG 2.2-122 wind turbines for two wind farms, totalling 453 MW. Both projects will be located in Bhuj, Gujarat, where the company will supply 202 MW for one project and 251 MW for the other.

The two wind projects for which Alfanar has secured the turbine supply agreement, are a part o the 600 MW project building capacity that was won by the company in the latest Solar Energy Corporation of India (SECI) auctions. The two wind farms are expected to be commissioned by 2020.
