ERCOT noted that it did not factor into the Dec. 1 CDR the potential resource capacity impacts of several U.S. Environmental Protection Agency regulations that are being implemented or have been proposed, the most immediate of which is the forthcoming Regional Haze Program Final Rule establishing a Federal Implementation Plan (FIP) for Texas. This rule is expected within the next several months, and, as proposed, would require scrubber upgrades or retrofits at 12 coal-fired units in ERCOT with a 2018-2020 compliance period.
ERCOT’s recent regulatory impact analysis, which focused on the Clean Power Plan (CPP) and the proposed Regional Haze Federal Implementation Plan (FIP) for Texas, indicated that at least 4,700 MW of coal generation is likely to be retired as a result of these regulations. Depending on the requirements in the final Regional Haze FIP, these retirements may occur within the next five years. These retirements are in addition to 2,300 MW of gas-steam and coal capacity (including the announced mothballing of CPS Energy’s J.T. Deely units 1 and 2 in late 2018) that the analysis found would retire under business as usual conditions.
