The Kleen Energy power plant is a 620 MW combined cycle electric generating facility located in Middletown, CT. The facility was completed in July, 2011. The plant consists of two Siemens SGT6-5000F dual fuel combustion turbines (natural gas and fuel oil), one high-pressure Siemens SST-5000 steam turbine, heat recovery steam generators, cooling towers, DCS instrument and control system, and a 345 kV gas-insulated switchyard and step-up transformers. It is one of the cleanest and most efficient natural gas power plants in the region. The project required expansion of natural gas and oil pipelines as well as development of a state-of-the art water project to deliver water to the plant from the Connecticut river. The project is sited on a former brownfield site which was used as a mining operation for decades. Development of the project, stabilized the site and stopped the runoff of the mining fines from entering the Connecticut River.
Members of the CT E&T team worked on all aspects of the project including obtaining local, state and federal permits, engineering and construction and financing.
