PNM Completes Shut Down of Units 2 and 3 at the San Juan Generating Station
LCG, December 21, 2017--PNM Resources' New Mexico utility, Public Service Co. of New Mexico (PNM), has completed the shutdown of two of the four units of its San Juan Generating Station (SHGS) near Farmington, New Mexico. Crews will now begin the process of cleaning out the units and completing other procedures to permanently retire the units. PNM's agreement with the U.S. Environmental Protection Agency (EPA) mandates that the units be completely out of service by December 31, 2017.
The SJGS had a net generating capacity of 1,683 MW, and the retirement of Units 2 and 3 will cause a reduction in plant capacity of 836 MW, or about half of the plant capacity. Unit 2 came online when the plant opened in 1973 and is the oldest unit at the power plant. Unit 3 began operation in 1979. PNM plans to replace that loss in generation with a diverse mix of increased renewable energy, existing nuclear power and natural gas generation.
The retirement of the two units is part of the Revised State Implementation Plan (Revised SIP), which resulted from an agreement among the New Mexico Environment Department, the EPA and PNM. Retiring the units is necessary for SJGS to comply with federal visibility regulations under the Clean Air Act. Retiring the two units reduces the plant's emissions, including carbon dioxide, as well as its use of coal and water, by approximately 50 percent.
PNM Resources' President, Chairman and CEO stated, "This agreement is the result of a strong collaboration among many parties, each of whom worked to find a solution in the best interests of New Mexicans. As we look ahead, there will be more challenges to face and tough decisions to make. The best way to achieve our shared vision of a clean, sustainable energy future will be to continue to work together."
In August 2015, PNM filed with the New Mexico Public Regulation Commission (NMPRC) a settlement agreement regarding the plan to retire two coal-fired units at SJGS. The agreement modified the original Stipulation filed in October 2014.
