In August 1988, the 110 MWe Nucla Station was added to the US DOE`s first round of Clean Coal Technology (CCT) Demonstration Projects. The objective was to demonstrate the successful repowering of an aging stoker-fired station with the first, utility-sized circulating fluidized bed boiler in the US. In cooperation with the Electric Power Research institute (EPRI), a detailed Test Program was carried out in order to quantify and assess the unit`s combustion and emissions performance, fuel flexibility and commercial viability. Completed in 1991, the results of this program were extensively documented and reported in a series of EPRI, DOE and international publications. At the conclusion of the Demonstration Program, the unit began commercial operation with an operating availability below expectations. Using the experience and knowledge gained through the Demonstration Program, Tri-State Generation and Transmission Association Inc. successfully completed upgrades to the unit in several areas with the goal of improving the overall reliability of the station. Since these modifications were completed in the fall of 1993, the unit has demonstrated significant improvements in availability; exceeding its pro forma operating goals to date. Combined with new fuel and power sales contracts, the investments have not only resulted in an economic turnaround for the station, but also have established the project as one of the first to begin repayment of DOE CCT funds as outlined in the Cooperative Agreement of 1987. Currently, Tri-State is continuing its investment in the station with upgrades to the coal handling system and the development of a first-of-a-kind CFB training simulator that mimics the station`s distributed digital control system. The latter is being developed as a tailored collaboration project with EPRI and is scheduled for complete in 1996.
