Mid-Kansas Electric Company to Use Reciprocating Engines in New Power Plant

LCG, August 30, 2012--Mid-Kansas Electric Company LLC announced Monday that it will construct a 110-MW power plant that will consist of 12, natural gas-fired reciprocating engines. The estimated cost of the project is $130 million.

The use of natural gas-fired, reciprocating engines is becoming more popular in areas where renewable power generation is growing, as the reciprocating engines are a scalable means to provide flexible generating capacity to complement intermittent electricity produced by renewables.

The new facility, Rubart Station, will be the first installation of Caterpillar Power Generation Systems' new G20CM34 natural gas-fueled reciprocating engine generator sets. The new, 20-cylinder model expands on the 12 and 16 cylinder models, and the engines can generate up to 10 MW.

The project will include 12 engines that will provide flexibility to step up (or down) power generation from the plant by turning on one unit after another.

"Our members will see multiple advantages when Rubart Station comes to fruition," said the president and CEO of Mid-Kansas. "Along with being incorporated into our existing generation fleet to meet our growing load, this type of generation resource has a fast start capability, allowing for quick response to market conditions and our system?s growing integration of wind energy."

The project site is located east of Ulysses in Grant County, Kansas and was selected based upon proximity to adequate transmission, a competitive natural gas supply, and the need for voltage resources to support substantial load growth and wind generation in the area.

Project permitting activities have commenced, and construction is scheduled to begin early next year and completed by April 2014.
