Con Edison uses more than 2000 MW of gas turbines to produce both peaking and base load power. In 1971, these units consumed approximately 6 million barrels of No. 2 oil and kerosine. This paper discusses fuel experiences with aircraft derivative engines and industrial engines. Data is presented from a fuel quality study at Con Edison. Conclusions and recommendations cover methods of fuel purchasing transportation, on-site fuel cleanup, and recommended housekeeping procedures.
