Trump EPA Finally Rolls Back Clean Power Plan

Trump EPA Finally Rolls Back Clean Power Plan

By: Jay Holloway

Today, EPA released the final Affordable Clean Energy (ACE) rule fulfilling the President’s promise to repeal the Obama EPA’s Clean Power Plan (CPP).  In addition to repealing the CPP, the ACE rule replaces the CPP.  The CPP placed severe CO2 limits on coal-fired power plants.  The CPP would have resulted in the shutdown of virtually all existing utility coal generation and forced utilities to switch to natural gas and renewable generation under a very aggressive time-frame.  Most, if not all, of the cost of the generation switch would have been borne by rate-payers.

The ACE rule, on the other hand, sets CO2 limits based on a joint process between EPA and the states.  This process involves states examining potential technologies and operation and maintenance practices that could potentially improve the efficiency of individual coal units.  Increasing the efficiency of these units will result in a reduction in CO2 emissions, because the units will burn less coal to generate the same amount of electricity.  All resulting limits must be set based on the CO2 emissions rate from a unit (i.e. pounds of CO2 emitted per megawatt hour generated).
