The largest municipally-owned electric and gas utility in the U.S. will close its remaining coal-fired power units by 2030. The board of trustees for San Antonio, Texas-based CPS Energy on Jan. 23 voted 4-1 to approve a plan to shutter the last two coal-burning units at the J.K. Spruce power plant.
The plan, known as Portfolio 2 or P2, approved Monday calls for the 560-MW Unit 1 at Spruce to be retired in 2027, with the 785-MW Unit 2 converted to burn natural gas beginning in 2028. Unit 1 was profiled by POWER in 2008; Unit 2 received a POWER Top Plant award in 2011.
The San Antonio City Council in October 2019 adopted a Climate Action and Adaptation Plan (CAAP), which sets a goal for the city to reduce greenhouse gas emissions by 40% by 2030 and become carbon neutral by 2050. CPS Energy, though moving to end coal-fired generation, already has acknowledged that San Antonio will not meet the CAAP goals under P2.
John Kosub, senior director of Energy Portfolio Analytics with CPS, earlier had said the utility “had a request from our board of trustees, to take a look at potentially discontinuing the use of coal by 2030. That is in support, to help the city of San Antonio reach their climate action and adaptation goals, which is net-zero carbon emissions by 2050.” Kosub has said the utility is working on a plan to maintain a reliable supply of electricity for the city while also meeting cleaner energy goals.
