Peaks and valleys
Florida Power Corp.?s Intercession City Power Plant has completed commercial start of its Model V84.3 Siemens gas turbine. The unit will be operated through a joint ownership agreement between Florida Power Corp. and Georgia Power Co. Florida Power will receive the output from the unit for eight months of the year, while Georgia Power will receive power the remaining four-month summer period. The arrangement is ideal because Florida Power is a winter-peaking utility and Georgia Power has a summer peak. Intercession City Unit P11 is rated at 144 MW with a simple-cycle efficiency of 36.1 percent with low NOx and CO emissions.
