## Reviewed overview

Century is a MidAmerican Energy wind farm in Wright and Hamilton counties, Iowa. MidAmerican repowered the 200 MW farm in 2017 as part of a program covering seven Iowa wind farms commissioned between 2004 and 2008, installing larger blades and hubs and replacing components inside the nacelles of its older GE turbines. The company expected annual energy production to rise 19 to 28 percent across the program.
