Delivering Backup Power
to Kansas Homes
Wind has long been a feature of the Kansas prairie. In fact, the state
has the second-highest wind potential in the U.S., second only to Texas.
Harnessing that renewable energy resource presents a big opportunity
for sustainable growth in the state. Wind energy, however, has one
signifi cant limitation – it is not available at the same level at all times.
For that reason, utility providers must complement their wind resources
with other generation sources that offer fl exibility and control to effec-
tively manage sudden changes in supply and demand of power. Caterpillar
has the right solutions and capabilities to meet that need.
Mid-Kansas Electric Company, LLC is a coalition of fi ve rural electric
cooperatives and one wholly-owned subsidiary that serve approximately
200,000 Kansans throughout 33 counties. Mid-Kansas selected Caterpillar
to equip Rubart Station, a backup generating station, to manage the
fl uctuations in available energy that are inherent with wind power.
The result is one of the largest natural gas-fi red power plants powered
by Cat® generator sets globally.
The new facility will include 20-cylinder, natural gas-fueled Cat
generator sets, each rated at 12,500 horsepower. Each engine will
drive a single generator, and the total electric output of Rubart Station
will be approximately 110 megawatts. The 12 units can be started and
ramped up quickly to meet rapidly changing market conditions, to
respond to wind resource changes and to assure full reliability within
the Mid-Kansas system.
This confi guration was chosen over other options based on several
factors, including high effi ciency, low emissions, exceptionally low
water consumption and fast load response.
“Mid-Kansas Electric is building this new station to help manage the
fl uctuations in available energy that are inherent with the growing pres-
ence of wind power in the area,” said Dean Powell, director of Global
Sales and Marketing, Caterpillar Power Generation Systems. “We are
excited that Mid-Kansas Electric will be the fi rst to install our new Cat®
G20CM34 Generator Sets. These generator sets will not only enhance
Mid-Kansas’ current diverse generation portfolio comprised of natural
gas, coal and wind but will also serve as a reliable and cost-effective
means to meet its coalition members’ growing demand for energy.”
The total electric output of Rubart Station
is 110 megawatts, which provides power
to 200,000 residents in Kansas.
