MidAmerican Completes Wind Projects in Iowa

LCG, December 15, 2005--MidAmerican Energy announced that it has completed the installation of all 257 wind turbines at two wind farm projects in Iowa. The combined electric generating capacity of the two projects is 360.5 MW.

The new wind farms are located in northwest Iowa in Sac and Buena Vista counties and in north central Iowa in Wright and Hamilton counties. The final wind turbine was commissioned on Tuesday at the Intrepid site in northwest Iowa, and the final turbine at the Century site in north central Iowa was commissioned on November 30.

The initial plan was to install 310.5 MW of capacity, and this phase was completed in September. An additional 50 MW of capacity was approved by the Iowa Utilities Board in January 2005 and is now installed and operational.

MidAmerican announced its final plans to proceed with the projects in September of last year, following the approval of the Production Tax Credit by the House and Senate. The Production Tax Credit, which provides for 1.5 cents for each kilowatt-hour of electricity produced, had expired at the end of 2003. When the credit expired, the financial viability of wind projects was significantly reduced, and many projects were put on hold.
