The Florida Department of Environmental Protection recently approved an air construction permit that will allow Florida Power and Light to undertake a major efficiency and power uprate project at a unit of its Manatee power plant.
The existing 2,750-MW plant has emissions units that include:
- Units 1 and 2 are fossil fuel-fired steam electrical generators (nominal 800 MW each). Unit 1 began commercial operation in 1976 and Unit 2 began commercial operation in 1977.
- Unit 3 is a “4 on 1” combined cycle system that consists of: four gas turbines (170 MW each), four 495 MMBtu/hr heat recovery steam generators, and a single steam turbine-electrical generator (470 MW). Unit 3 has a total current capacity of about 1,150 MW. These emissions units commenced commercial operation in May 2005.
“This permitting action revises and adds certain conditions in the underlying air construction permit No. 0810010- 006-AC (PSD-FL-328) for Unit 3,” said a Dec. 19, 2013, DEP approval document. “The revised condition is primarily related to the language update of Unit 3 permitted capacity. The new conditions added are the authorization to replace the GE 7FA.03 turbine components with the GE 7FA.04 components to improve the efficiency of Unit 3. Each turbine new components would allow greater power output from 170 to 184 MW and higher input rate from 1600 to 1659 MMBtu/hour. Total new generating capacity of Unit 3 would increase approximately from 1150 to 1206 MW as a result of this project.”
