DES MOINES, Iowa -- November 30, 2012

Last evening, MidAmerican Energy Company was honored with the Green Energy
Supplier Award at the 2012 Platts Global Energy Awards ceremony in New York,
N.Y. The company received the award for its 2011 and 2012 wind expansion
projects in Iowa, which add another 1,001 megawatts of renewable energy to the
company’s generation portfolio.

The awards ceremony was attended by energy executives from around the world.

The nomination noted MidAmerican Energy’s diverse generation portfolio. By
year-end 2012 when the company’s 407.1-megawatt wind expansion is complete,
MidAmerican Energy will have nearly 2,300 megawatts of owned wind generation
capacity.

MidAmerican Energy is the No. 1 owner of wind-powered generation capacity
among rate-regulated utilities in the U.S. When its wind expansion is
complete, approximately 30 percent of MidAmerican Energy’s total owned
generation capacity will come from wind.

“MidAmerican Energy believes the best way to meet customers’ energy needs is
to provide reliable, affordable and environmentally responsible energy through
a diversified generation portfolio,” said Bill Fehrman, president and CEO,
MidAmerican Energy. “We know that meeting our customers’ expectations requires
action today and planning for our energy future.”

“By year-end 2012, MidAmerican Energy will have 1,267 owned wind turbines
generating electricity in Iowa, with each wind turbine serving as a visible
demonstration of the company’s commitment to green energy,” Fehrman added.

As a finalist in the Stewardship Award category, MidAmerican Energy also
received the Award of Excellence at a special luncheon at the Platts Global
Energy Outlook Forum prior to the awards ceremony. Since 2008, Platts has
bestowed a special award on a group of finalists in a particular category,
