Wärtsilä has been awarded a contract to supply a 56-MW Smart Power Generation power plant to Coffeyville Municipal Light & Power (CMLP) in Kansas.
The power station will feature three gas-fired Wärtsilä 50SG engines, which are expected to reach commercial operations in January 2017.
“Our current units take 6–8 hours to full load. We need much more flexibility in the Southwest Power Pool (SPP) market,” said CMLP’s Director Gene Ratzlaff. “We like the fact that Wärtsilä engines can go to full power in less than 10 minutes. That makes us much more competitive.”
The new power station will provide peaking power and support booming wind energy in the state.
“We have so much wind power that if the wind stops blowing, you can lose hundreds of megawatts of power. Fast capacity is needed to compensate the loss,” Ratzlaff said.
According to a recent white paper by Wärtsilä and Ascend Analytics, an engine-based power plant can make 740 percent more profit in the SPP market than an open-cycle gas turbine, because engines follow electricity prices more rapidly and efficiently than gas turbines. The comparison was made against real market prices from March to September 2014.
The SPP is a regional transmission organization operating in nine Southwestern states.
