Vision: San Antonio leads the nation in the generation and delivery of clean, reliable, affordable energy.

Renewable Energy

Wind, Solar, and Gas

San Antonio is looking to lead the nation in the generation and delivery of clean, reliable, affordable energy. CPS Energy, our energy provider, is the nation’s largest municipally owned energy utility and is committed to growing its supply of emission-free electricity from wind, solar, and landfill gas.

We track renewable energy by measuring the porportion of electricity generation we as a community use that is supplied from renewable energy resources.

2040 - Goal


CPS Energy has a goal to have 40% of its electrical generation capacity to come from renewable energy in 2040. They are on their way to meeting this goal.

In 2017, San Antonio had 19% of its generation capacity come from renewable energy resources.That's nearly half way to meeting our 2040 goal!

San Antonio Solar PV Systems

San Antonio has 609 MW of solar panels installed across our City which can provide enough energy to power over 120,000 homes. The majority of this energy is "utility scale" (meaning the energy goes directly onto our electricity grid and does not first supply energy to a building). The rest of our solar energy comes from smaller systems found on homes and buildings.

The City of San Antonio participates in CPS Energy’s SolarHostSA Program, which installs, operates, and maintains solar installations on City facilities. Currently, we have solar panels on five facilities and look to double that number within the year!

Rethinking Our Energy Use

Energy Consumption

San Antonio is changing how we look at our energy needs. We treat our energy use with thought, purpose, and respect. Reducing the amount of energy we use each day will save us money, protect our air, and water and conserve our fuel supplies so they can last longer. Reducing our energy use is an important step in leading healthy lives.

Energy from different sources is measured in different ways – electricity is measured in kWh, natural gas in therms, oil in gallons. We can convert these different measures into a common measure- million British Thermal Units (MMBTU) -to better understand and compare total energy use.

San Antonio Energy Use by Sector

In 2017, San Antonio used over 22 million MWh of electricity.  Most of this energy was used in our homes and in commercial stores and industries (Comm. & Ind.) at 42.5 and 42.3%, respectively. Nearly thirteen percent was used by our public authorities. Wholesale electricity buyers made up just over two percent and outdoor lighting accounted for less than half of one percent.
