2018 CO2 Emission Projections for the SESARM States Prepared by: Byeong-Uk Kim, Jim Boylan, and Keith Bentley GA EPD – Air Protection Branch October 22, 2013
Background • The President’s climate action plan in June 2013 reiterated his 2009 goal of a 17% reduction in CO2 emissions by 2020 from a 2005 baseline. • EGU emissions trending downward due to: • Lower natural gas prices • Closure of older inefficient units • Compliance with CAIR and MATS • Compliance with state rules • Increases in renewable energy and nuclear • EPA seeking state input on how 111(d) requirements should be implemented • Need reference point as starting point for discussions
Approach • Extracted 2018 heat input values by fuel type (coal, oil, gas) from ERTAC EGU projection tool. • 2011 CAMD heat input data was used as the starting point for the projections • Applied ERTAC growth factors by fuel type from the AEO 2013 Report • Applied emission controls submitted by the states • Applied CO2 emission factors (TPY CO2/MMBTU) to projected 2018 heat inputs for each fuel type. • State specific CO2 emission factors (EFs) derived from 2005 CAMD data for coal, oil, and gas • National CO2 emission factors for coal, oil, and gas • Compared 2005 and 2011 CO2 emissions with 2018 projected CO2 emissions.
State Derived CO2 Emission Factors *Due to 2005 and 2011 CAMD data issues with WV Oil, SEMAP Oil CO2 Emission Factor was based on data from nine states.
Tennessee *Due to limited data samples for TN Gasin the 2005 CAMD data, 2011 CAMD data was used to derive the TN CO2 Emission Factor for Gas.
West Virginia *2005 and 2011 CAMD data for WV included heat input data for Oil, but no CO2 emissions. Therefore, 2005 and 2011 CO2 emissions for WV were back-calculated with the SEMAP CO2 Emission Factor. **2005 and 2011 CO2 emissions for WV were back-calculated with the National CO2 Emission Factor.
Conclusions • Different methods give slightly different results • Percent reduction varies between states • Need closer examination of data and assumptions • SEMAP states overall project 17-18% reduction from 2005-2018 • Some people are happier than others about the situation
