FACT SHEET Proposed Affordable Clean Energy Rule - Comparison of ACE and CPP CPP ACE Rule CO2 emissions The ACE Rule continues downward C02 trend, pushing power sector C02 emissions to around 34% below 2005 levels (similar to CPP). EPA's policy role Expansive program to regulate entire energy sector Inserted EPA into energy policy Reshaped the grid and energy markets Reasonable program focused on potential upgrades to coal plants Keeps EPA focused on environmental policy Leaves the market alone and doesn't pick winners and losers Coal impacts Shut down coal Keeps coal plants open and makes them more efficient Reliability and Promoted disinvestment in coal in energy mix favor of renewables and natural gas Promotes investments to make coal plants cleaner, modern and more efficient Relied on fuel switching No fuel switching Federal and state roles Set a single federal standard and forced states to adopt it Lets states set their own standards that meet federal guideline consistent with current law State plans and deadlines Included detailed requirements for state plans Includes flexible guidelines for states to evaluate potential for energy efficiency Required states to report to EPA up to 6 times over 15 years, starting 1 year after final rule States may only need to make 1 submission to EPA, and 3 years after final rule New Source No changes to NSR permitting Review permitting requirements, deterring energy efficiency upgrades at coal plants Targeted updates to NSR so coal plants can improve efficiency and modernize Retained annual test in NSR, meaning efficiency upgrades would likely trigger more requirements Proposes initial hourly trigger for NSR, meaning efficiency projects won't trigger additional requirements FOR MORE INFORMATION https://www.epa.gov/stationarv-sources-air-pollution/proposal-affordable-clean-energy-ace-rule ------- |
