Electric Power

Electric Service Area

CPS Energy is an innovative energy provider that uses a diverse fuel mix, including clean energy generated from wind, solar and landfill gas to power San Antonio. Its New Energy Economy initiative helped establish a solar manufacturing hub in the community and attracted companies committed to clean energy and energy efficiency. CPS Energy’s strategic alliance with its New Energy Economy partners is currently reaping a $1 billion economic impact, and millions in educational investment. These benefits are being realized while the energy company works to meet its goal of achieving 1,500 megawatts (MW) of renewable energy power, or 20% of total generation capacity, by 2020. CPS Energy works closely with its commercial and industrial clients to help them increase energy efficiency and manage power usage.

Generating Plants

CPS Energy’s diverse fuel mix includes coal, nuclear, natural gas, solar, wind, and landfill gas, generating a total capacity of 7,773 MW for its San Antonio area service territory. CPS Energy registered 4,858 MW of peak demand on August 11, 2014.

Generating Plants

At the end of fiscal year (January 31, 2010), CPS Energy utilize a diverse fuel mix including coal, nuclear, natural gas, solar and wind to generate a total capacity of 7,006 MW for the San Antonio service territory. CPS Energy registered 4,738 MW of peak demand on August 23, 2010.

Electric Transmission System

The CPS Energy Transmission System interconnects the generating plants with distribution substations located throughout its service area. The system is part of the interconnected transmission grid operated by the Electric Reliability Council of Texas (ERCOT). ERCOT serves as the regional security coordinator for the North American Reliability Council, the Independent System Operator and the Regional Transmission Organization for the transmission grid serving the majority of Texas.

  • Voltages: 138 kV, 345 kV
  • Size of Lines: Lines range from 4/0 to 2,000 MCM (2 bundle)
  • Description of System: Networked

Electric Distribution System

CPS Energy distributes power through strategically located distribution substations. Each substation has from one to six power transformers with capabilities based on the load density. These substations feed approximately 580 distribution circuits, serving retail customers in the CPS Energy service area. As of January 2015, CPS Energy served nearly 772,000 electric customers.

  • Voltages: 4.16 kV, 13.2 kV, 34.5 kV
  • Size of Lines: Range up to 556 MCM

Service Continuity

A well maintained, well-engineered electric system and a temperate climate help CPS Energy provide continuous, reliable electric service. From the Emergency Management Center (EMC), highly trained technicians using the latest in computer technology monitor the flow of energy in CPS Energy’s 1,515-square-mile service area 24 hours a day.

Electric Rates

The annual average electric rates for industrial users in San Antonio are competitive when compared to other utilities across the state and nation. Residential bills are affordable, ranking lowest when compared to the 20 largest U.S. cities. Using the appropriate and most advantageous rate schedule, CPS Energy economic development staff will gladly calculate an estimated electric bill based on specific consumption (kWh) and demand (KW) figures.

Economic Incentive Rider

CPS Energy has an economic incentive rider applicable to entities that bring, or add, at least 10 MW of new electric load to CPS Energy.

Natural Gas

CPS Energy provides natural gas to nearly  337,000 residential, commercial and industrial customers in a 640-square-mile area in San Antonio, Bexar County and parts of Comal, Guadalupe and Medina counties. The system can be expanded to serve customers in other areas. Gas Transmission System

Gas Transmission System

The Gas Transmission System has 88 miles of 16-inch through 30-inch transmission mains that feed an extensive intermediate pressure supply system and provide access to four major natural gas transmission lines and numerous natural gas suppliers.

Gas Distribution System

Nearly 5,300 miles of 14-inch to 30-inch cathodically protected steel and plastic mains make up the gas distribution system. CPS Energy has sufficient capacity to supply additional industrial load. Gas Service Continuity

Gas Service Continuity

As with the electric system, personnel from the Emergency Management Center (EMC) continuously monitor the natural gas system and remotely control all major components. Customers receive gas via a modern, reliable pipeline system that delivers the fuel even during heavy winter peak demand. Some 250 highly trained employees ensure reliability around the clock. As a natural gas distribution utility, CPS Energy adheres to the natural gas supply and priority use regulations established by the Texas Railroad Commission and the Federal Government. CPS Energy uses a pool of 60 gas providers to maintain competitive prices, guarantee adequate supply, and meet customer demands.

Gas Rates

Gas rates are below the national average and competitive when compared to other utilities across the state. This is due largely to the fact that gas supply is more accessible and can be secured more economically in this area of the country than in many other areas. Using the appropriate and most advantageous rate schedule, CPS Energy staff will gladly calculate an estimated annual bill based upon specific consumption and demand figures.

Development Plans

Electric and Natural Gas Systems

Ranked as one of the best-managed and most economical utilities in the nation, CPS Energy is positioned to handle present needs as well the vibrant future growth expected in the San Antonio area.

Sound financial management enables the utility to enjoy AA+, Aa1, and AA ratings from Fitch Ratings, Moody’s Investors Service, Inc., and Standard and Poor’s Rating Services, respectively.

The gas system is one of the best, most reliable systems in the country, offering an ample gas supply. CPS Energy has sufficient capacity to provide economical natural gas to new industrial development and growth in the San Antonio area. The CPS Energy electric and gas systems continue to meet present and future energy requirements and will continue to provide reliable gas and electric service for its customers. CPS Energy also continues to prepare for the future.

The North American Electric Reliability Council (NERC) is urging utilities to have both primary and secondary control centers. CPS Energy’s Energy Management Center (EMC) utilizes one of the most advanced computer controlled, redundant online utility control systems available, ensuring system reliability by being able to control field switches past the substation.

In addition, CPS Energy has a state-of-the-art communications system, which enhances internal operations, as well as allows the utility to communicate with its customers.
