In opting to burn lignite, the Texas Municipal Power Agency (TMPA) and Houston Lighting and Power Co. (HL and P) traded the local availability and relatively low cost of this young coal against the problems inherent in working with a low-heating-value, erosive fuel. Though both utilities factored into their designs experience from other lignite-fired plants, they still had a considerable number of equipment modifications to make after startup to ensure reliable, efficient operation. Advancements in the state-of-the-art in handling and burning lignite contributed by TMPA and HLandP undoubtedly will facilitate the design and operation of future plants. Here are the details. TMPA's Gibbons Creek steam/electric station located in Grimes County, Texas, is a 408-MW, single unit, lignite-fired mine-mouth plant. It began operation in November, 1982. Many of the unique features of the plant, and most of the problems encountered during shakedown are related to the properties of the fuel and ash. The fuel is an extremely low-grade Texas lignite from the Jackson formation.
