摘要

Operating experience with the new distributed control system has been good. It has functioned reliably with little operator intervention, and the plant heat rate has improved appreciably. Quantifying return on investment over the three-year operating period through 1999 is difficult because of changes in the costs of purchased power and natural gas. Overall, there has been a substantial reduction in the use of natural gas and a significant drop in the amount of purchased power.
