The Cascaded Humidified Advanced Turbine (CHAT) concept applied to small capacity simple cycle gas turbines fulfills the need for a small capacity, highly efficient, cost effective, flexible, and reliable plant with near term delivery. The objective of this report is to provide a status of the development of the small CHAT plant based including performance and cost estimates, potential suppliers, and operating advantages offered by the cycle itself. The small CHAT plant based upon the use of the Allison 501 KM7 engine on the low pressure power generation shaft produces 11.1 MW at ISO conditions with a net plant efficiency of 44.1%, LHV. This design requires only minor modification to the Allison KM engine. At maximum power, the plant can produce 12.8 MW at an efficiency of 43.1%. The estimated turn key capital cost of the plant at maximum power rating is approximately $750/kW. The next generation CHAT plant which requires additional modification to the Allison shaft is expected to produce 12.2 MW at 46.4% efficiency.
