Two Plants Seen Ready for June

LCG, Apr. 25, 2002--Two 550-megawatt, gas-fired power plants are seen as being ready to operate starting in June, according to developer Kinder Morgan.

Williams Cos. will provide natural gas to a plant being developed in Jackson, Mich., and will buy the plant's entire output as part of a tolling agreement with Kinder Morgan. The plant is owned by financial services firm CIT, which is part of Tyco International. The plant is expected to be operating at the end of June.

The other plant is sited near Little Rock, Ark., and will be owned and operated by Mirant Corp., which will provide natural gas and sell the plant's output. The Arkansas-based plant is expected to begin operations on June 1.

Both plants will utilize a design that is meant to achieve the fuel efficiency of a combined-cycle power plant, and the quick start-up times of a simple-cycle peaking plant. Combined-cycle plants capture the waste heat from burning fuel in order to heat steam to provide additional energy to drive a turbine, whereas waste heat is otherwise dispersed without contributing to power generation. A simple-cycle peaking plant is an internal combustion engine that can achieve maximum output in less time than a steam turbine or traditional combined-cycle configuration.
