Integrated Gasification Combined-Cycle Facility IGCC Facility Integrated Gasification Combined-Cycle Facility

TEC Consent Decree (CD) and Consent Final Judgement (CFJ) TEC is required to repower F.J. Gannon Station, a coal fired electric generation facility, to Bayside Power Station, a natural gas fired electric generation facility TEC is required to optimize the Electrostatic Precipitators (ESPs) at Big Bend Station TEC is required to upgrade the removal efficiency and availability of the scrubbers (FGDs) at Big Bend Station TEC is required to make substantial early and long term reductions in NOX emissions from the units at Big Bend Station by 2010 Upon completion of the above projects, emissions levels from all TEC units will be comparable to emissions levels from new units utilizing the same fuels

Nitrogen Oxides (NOX) By 2010, TEC will have reduced NOX system wide by approximately 85% Gannon NOX reductions: repower to natural gas Big Bend NOX reductions: addition of Selective Catalytic Reduction (SCR) system NOX emissions from Polk Unit 1 IGCC were already low, and were reduced again prior to July 2003

Sulfur Dioxide (SO2) By 2010, TEC will have reduced SO2 system wide by approximately 89% Gannon SO2 reductions: repowering to natural gas Big Bend SO2 reductions: all units fully scrubbed at all times SO2 emissions from Polk Unit 1 IGCC are already low
