CPS Energy is the nation’s largest municipally owned energy utility providing both natural gas and electric service. Acquired by the City of San Antonio in 1942, today we serve more than 771,000 electric customers and 336,000 natural gas customers in and around the seventh-largest city in the nation. We serve customers in Bexar County and portions of Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina, and Wilson counties (1,515-square-mile service area).

We’re proud of the fact that our customers’ combined (electricity and natural gas) energy bills rank among the lowest of the nation’s 20 largest cities. Thanks to a diverse mix of fuels, our electricity is not only affordable, it’s reliable. Today, coal comprises almost 42 percent of our daily generation mix, followed by nuclear energy at nearly 25 percent. Renewable energy, including wind, solar and landfill-generated methane gas, account for almost 11 percent, while natural gas and purchased power comprise the remaining 23 percent. Our Save for Tomorrow Energy Plan (STEP) looks to reduce our community’s demand for electricity by 771 megawatts – the output of a large power plant – by 2020. To achieve this ambitious goal, CPS Energy has committed millions of dollars to energy efficiency rebates and programs for our customers. Today, as part of San Antonio's New Energy Economy, we're also investing in innovative technologies that will protect our environment, help our customers use energy more wisely, and leverage valuable economic development opportunities for our community’s future.

We’re not just the local power company. We are an integral part of this community. Our revenues support vital public services in Greater San Antonio. The environment remains a high priority despite our community’s growing demand for power. And our 3,000 employees are committed to doing their part to support local charities with 14,000 volunteer hours and a record-setting $1 million pledge to United Way. At CPS Energy, we are proud of who we are and our spirit of giving.
