Why we need a diverse electricity generation portfolio: House hearing 2013

Why we need a diverse electricity generation portfolio: House hearing 2013

  • June 5, 2015. Proposed Clean Power Plan would accelerate renewable additions and coal plant retirements. U.S. Energy Information Administration
  • Even without the Clean Power Plan rule (CPP), 40 GW of coal capacity is expected to retire by 2040. If the CPP is passed, between 90 to 101 GW of coal plants may retire (EIA June 5 2015).
  • The EIA expects 46 to 62 GW of natural gas plant retirements replaced by 166 GW.
  • Coal plant retirement 40.1 GW by 2025 EIA DOE 2015 Annual energy outlook with projections to 2040.

Even in the absence of the proposed Clean Power Plan rule, 40 GW of existing coal-fired capacity and 46 GW of existing natural gas/oil-fired capacity are expected to retire through 2040 in the Reference case. Cases that implement the proposed Clean Power Plan rule accelerate and amplify these retirements, especially for coal. In the Base Policy case, 90 GW of coal-fired capacity and 62 GW of natural gas/oil-fired capacity retire by 2040. In the Policy Extension case, as emission rates continue declining after 2030, 101 GW of coal-fired generating capacity and 74 GW of natural gas/oil-fired generating capacity retire by 2040. The timing of the coal retirements is heavily influenced by implementation of environmental rules that may require power plant operators to either incur costs to retrofit power plants or receive less revenue because of lower levels of operation. As a result, coal retirements occur during the implementation of the Mercury and Air Toxics rule (in both the Reference case and Base Policy case), and in the initial year of the Clean Policy Plan implementation.

If EPA’s clean power plan and mercury and air toxis standards passes, then 60 GW of coal plants may retire early. EIA. March 20, 2014 Planned coal-fired power plant retirements continue to increase
