Policy Context & Scientific Grounding:
The EPA power plant pollution rules, previously enacted under Section 111 of the Clean Air Act, mandated aggressive greenhouse gas reductions (including requirement of 90% carbon capture and storage or co-firing for long-operating coal and baseload gas plants). Repealing these rules eliminates mandatory abatement investments, keeping older, higher-emitting fossil units running at unabated emission rates. This simulator models the direct delta between fleet-wide unabated combustion versus regulated emission benchmarks across flexible grid capacity assumptions.
