Coal has been an important source of fuel for CPS Energy for decades. Our utility currently has two coal units that turn low-sulfur coal into electrical power for our customers.

At the J.K. Spruce 1 and 2, located on Calaveras Lake in south Bexar County, coal is used to produce more than 1,300 megawatts of affordable and reliable electrical power for Greater San Antonio.

In 2011, CPS Energy made a commitment to close our first and oldest coal plant, Deely, at the end of 2018. Before the clock struck midnight to ring in 2019, the plant officially shut down.

As part of our City of San Antonio’s Climate Action and Adaptation Plan (CAAP), we are on schedule to retire coal energy production by 2028.
