Florida Power and Light revises Manatee permit to cover uprated capacity

The Florida Department of Environmental Protection on Feb. 11 went out for comment on a Florida Power and Light application to revise a Title V air permit for the Manatee power plant to cover a recent upgrade project for Unit 3.

“The applicant applied on January 16, 2015 to the Department for a Title V air operation permit revision to incorporate the provisions of final air construction permit No. 0810010-020-AC (PSD-FL-328D), which authorized the installation of the new GE FA.04 turbine components to improve the efficiency and power output of Unit 3,” said a DEP notice. “In addition, new National Emission Standards for Hazardous Air Pollutants applicable to Units 1 and 2 were incorporated into the permit along with several new facility wide reporting requirements. These changes revise Title V air operation permit No. 0810010-019-AV.”

Manatee is a nominal 2,806-MW facility that consists of Units 1 and 2 which are two fossil fuel steam generators, Unit 3 which is a “4-on-1” gas-fired combined cycle unit and associated support equipment.

  • Units 1 and 2 are each a Foster-Wheeler steam generator rated at 800 MW output. These units burn a variable combination of natural gas, No. 6 fuel oil, No. 2 fuel oil, propane, and used oil.
  • Unit 3 consists of four (“4-on-1”) nominal 184 MW General Electric Model PG7241(FA) gas-fired turbine-electrical generators, four 495 million British thermal units per hour supplementary-fired heat recovery steam generators (HRSG) with selective catalytic reduction reactors, a single nominal 470 MW steam-electrical generator that serves all four gas turbine/HRSG systems. The total generating capacity of the “4-on-1” combined cycle system Unit 3 is currently 1,206 MW.

After the installation of the GE 7FA.04 components mentioned above, the design gross power output from each turbine at Unit 3 changed from 170 MW to 184 MW at 59 degrees F while the total generating capacity of the “4 on 1” combined cycle system changed from the prior 1,150 MW to the current 1,206 MW.
