Orlando gets permit for uprate of Stanton Energy Center Unit 2

The Florida Department of Environmental Protection on May 7 issued a final air permit to the Orlando Utilities Commission for a turbine blade replacement on the coal-fired Unit 2 at the Stanton Energy Center.

“This is the final air construction permit, which authorizes the replacement of the high pressure and intermediate pressure (HP/IP) portions of the Stanton Energy Center Unit 2 steam turbine with improved blade technology,” said a DEP notice. “It is expected that this turbine replacement effort will increase the efficiency of Unit 2, providing an increase in power generation output capability without a corresponding increase in fuel consumption or annual generation potential.”

The Unit 2 turbine project is expected to result in approximately 15.1 MW of additional capacity, without any additional fuel usage or increase in energy output by the boiler. Because there will be no increase in heat input or annual hours of operation, air pollutant emissions from Unit 2 will see no increase after the turbine replacement relative to historical levels.

The Stanton facility has two coal-fired steam generating facilities, Unit No. 1 and Unit No. 2; also, there are storage and handling facilities at the site for solid fuels, fly ash, limestone, gypsum, slag and bottom ash.

  • Unit No. 1 consists of a Babcock and Wilcox boiler/steam generator (Model RB 611) and steam turbine, which drives a generator with a nameplate rating of 468 MW.
  • Unit No. 2 consists of a Babcock and Wilcox boiler/steam generator (Model RB 621) and steam turbine, which drives a generator with a nameplate rating of 468 MW.
