The Florida Department of Environmental Protection on Jan. 6 issued to Florida Power and Light a final air construction permit that authorizes the installation of General Electric 7FA.04 components to improve the performance of Units 3 and 4 (Units 3A through 4B) at the FPL Martin Power Plant in Martin County.
The plant has two 863.3-MW oil- and gas-fired steam units (Units 1 and 2), two 2-on-1 oil- and gas-fired combined cycle combustion turbines (Units 3 and 4, 500 MW each), and a 4-on-1 combined cycle system (Unit 8) including four oil- and -gas-fired combustion turbines (1,150 MW).
FPL was permitted to upgrade the four combustion turbines (Units 3A through 4B, Units 3 and 4) during an otherwise routine maintenance outage. The changes will increase the efficiency of each CT by installing new hot gas path components, combustion liners, flow sleeves and new control software characteristic of the more recent GE Model 7FA.04 CT.
Also on Jan. 6, the DEP issued a separate final air construction permit to FPL that authorizes the installation of GE 7FA.05 compressor components to improve the performance of Unit 8 (Units 8A through 8D) at Martin. This permit allows the installation of new GE turbine components to improve the performance of Unit 8 (designated as Units 8A through 8D). This includes new compressor components, new hot gas path components and new control software.
