U.S. utility to boost its wind output by 150%

DES MOINES, Iowa, US, May 03, 2006 (Refocus Weekly)

A U.S. utility will install 545 MW of new windfarms in Iowa, increasing its wind capacity from its current 361 MW of turbines in the state.

MidAmerican Energy, which claims to have the largest installed wind capacity of all rate-regulated utilities in the country, has received approval from the Iowa Utilities Board to install up to 545 MW of additional wind-powered generation. The size, cost and locations of the windfarms have not been finalized, but power rates will remain at current levels until at least 2010.

The first phase of the expansion will be built in Carroll and Crawford counties in west-central Iowa and is scheduled to be completed in 2006. This 99-megawatt project, being constructed by Invenergy Wind Development Iowa LLC, will utilize 66 GE Energy 1.5-megawatt wind turbines.

MidAmerican currently owns and operates 360.5 MW of wind facilities in northwest and north-central Iowa, with sufficient output for 100,000 homes. The new projects will use improved turbine technology and generate power for 200,000 more customers, while displacing the annual emission of 1.6 megatonne of carbon dioxide.

The utility’s existing 361 MW of wind energy avoid 805,000 tons of CO2 per year.

“This project will bring additional renewable energy to Iowans while keeping electric rates stable for our customers,” says president Todd Raba. “We are again adding renewable energy to our diversified generation portfolio in a way that makes sense for our customers, our company and the state.”

MidAmerican built a 311 MW windfarm in response to a challenge made in 2003 by Iowa governor Tom Vilsack to install 1,000 MW of green power by 2010. At that time, Vilsack’s challenge would have required the addition of 500 MW of renewables.

If the entire 545 MW of wind power were installed by the end of 2007, MidAmerican would own or have under contract more than 1,000 MW of wind, biomass and hydroelectric energy in Iowa. The American Wind Energy Association says Iowa currently has 830 MW of wind capacity, ranking third behind California and Texas in the output from wind turbines.

“MidAmerican has stepped forward as one of the real leaders within the electric utility industry related to wind energy, and the state of Iowa will be reaping a wide range of benefits as a result: cleaner air, new jobs, growing revenue for farmers and local governments, and stable electric rates for consumers,” says Randall Swisher of AWEA.

“MidAmerican is investing in our state’s energy future and in the lives of our communities and residents with the creation of construction jobs, not only for this project, but also with the $1.5 billion investment the company has in its other new electric generation projects in Council Bluffs, Des Moines and northwest and north central Iowa,”says Mary Lawyer of the Iowa Department of Economic Development. “Projects like this are key drivers in economic development for our state.”

MidAmerican has also reached agreement with the Iowa Farmers Union to facilitate the sale of wind power from small community-based projects. Under the terms of the agreement, the utility will purchase 40 MW from community projects that are less than 2.5 MW in size.
