IGCC Facility

Integrated Gasification Combined-Cycle Facility

tec consent decree cd and consent final judgement cfj
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 no x
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

    • 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

    • 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

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
