  1. Tampa Electric Company’sEmission Reduction Program 2005 Update

  2. IGCC Facility Integrated Gasification Combined-Cycle Facility

  3. 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

  4. 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

  6. 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

  8. Particulate Matter (PM) • By 2010, TEC will have reduced PM system wide by approximately 70% • Gannon PM reductions: repowering to natural gas • Big Bend PM reductions: improvements to ESPs and all units fully scrubbed at all times • PM emissions from Polk Unit 1 IGCC are already low

  10. Mercury (Hg) • By 2010, TEC will have reduced Mercury system wide by approximately 73% • Gannon Hg reductions: repowering to natural gas • Big Bend Hg reductions: currently achieving co-benefits from existing pollution control technologies - electrostatic precipitators (ESPs) and flue gas desulfurization (FGDs or scrubbers) systems, additional co-benefits expected from addition of SCRs • Hg emissions from Polk Unit 1 IGCC are already low

  12. Carbon Dioxide (CO2) • By 2005, TEC will have reduced CO2 system wide to at or below 1990 levels (approx. 23% reduction) • CO2 emissions reductions accomplished through repowering of Gannon Station and unit efficiency improvements
