Energy and Buildings
San Antonio continues to lead by example with the approval of the largest on-site solar project by a local Texas Government. Find out if a facility near you will be outfitted with a solar photovoltaic (PV) system.
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.
UNIT | A megawatt hour (Mwh) is equal to 1,000 Kilowatt hours (Kwh). It is equal to 1,000 kilowatts of electricity used continuously for one hour. It is about equivalent to the amount of electricity used by about 330 homes during one hour. | MWhMegawatt Hour |

Did you know?
CPS Energy created their Save for Tomorrow Energy Plan (STEP) to reduce the growth in our community’s demand for electricity by 771 MW by 2020. That’s the output of a large power plant! And with the help of the community, that goal was met a year ahead of time. Check out the progress for the STEP program!
Renewable Energy
Wind, Solar, and Landfill Gas
San Antonio is looking to lead the nation in the generation and delivery of clean, reliable, and 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 energy sources.
Renewable Energy
San Antonio Solar PV Systems
The energy supply from CPS Energy includes 609 MW of solar capacity from around the region, 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.

SolarHostSA
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!
Renewable Energy
Municipal Solar
The City of San Antonio is working with Big Sun Solar - a small, locally owned business here in San Antonio - to install solar panels on various buildings around the City! There are 42 municipal solar projects and six have been completed so far. The remaining 36 sites will be completed in the next two years. For each building, 70% of the energy costs will be offset due to the installed solar panels!
For more information on the solar projects and to view an interactive map of the locations and see their current construction status, visit the Big Sun Solar San Antonio Project page.

Building a Sustainable Future
San Antonio seeks to incorporate more sustainable practices within the
physical structures of the City's built environment; specifically our
buildings, water and sewer lines, stormwater systems, wastewater
treatment facilities, and other infrastructure. By making these more
sustainable, we will reduce our energy and water use which will make our air cleaner and our environment healthier.
San
Antonians are fortunate as there are three different ways they can get
their homes and businesses recognized for incorporating sustainability
aspects into their designs. They include a local initiative called Build San Antonio Green (for homes, multifamily and commercial) and two national initiatives, Energy Star and LEED for all building types.

CPS Energy Retrofit Certification from BSAG
It's not just homes that can be certified by BSAG. CPS Energy's headquarters recently became the first-ever BSAG certified commercial retrofit. The 200,000 square foot building received a level 2 certification signifying that the building is seeing 10% or greater energy savings over the projected amount. In fact, the new building is 60% more efficient than the previous one!
A few reasons why the new headquarters building is seeing such a drastic savings in energy use include:
- high performing window systems which reduce heat coming into the building
- energy and water efficient systems and equipment
- employee EV charging parking spaces
- high efficiency HVAC systems
- low-impact landscaping
- rain catchment systems
San Antonio Facility Design Guidelines and Standards
The City of San Antonio developed an energy policy called The Facility Design Guidelines and Standards, which requires all City-owned and managed buildings and operations to incorporate sustainable design and energy efficiency principles. These guidelines also provide the foundation for including sustainable practices on municipal facilities and to further reduce our environmental impact of our government operations.

Benchmarking & Disclosure
Reaching our goals for energy efficiency will need both engagement by the private sector and a way to better track our progress. Building benchmarking and disclosure is a key strategy to advance both of those requirements. By increasing transparency in building performance, building owners will be incentivized to race to the top. As the savings and recognition enjoyed by owners and tenants of the most efficient buildings are made visible, efficiency will be sought after more and more. Unleashing market forces in this way has had impressive results in other cities, including:
- Chicago: Energy consumption down 5.2% from 2014 to 2018. $15.1 million bill savings per year.
- Minneapolis: Energy consumption down 3.4% from 2014 to 2016. $21 million bill savings per year.
- Denver: Energy consumption down 4.5% from 2017 to 2018. $13.5 million bill savings per year.
- New York: Energy consumption down 10% from 2010 to 2015.
- Seattle: Energy consumption down 3% from 2014 to 2015.
- San Francisco: Energy consumption down 7.9% from 2010 to 2014.

Sustainability Upgrades with PACE program
On March 5, 2020, the City of San Antonio City Council officially established the Property Assessed Clean Energy (PACE) program within the city limits. PACE is an innovative financing tool that allows owners of commercial, industrial, nonprofit, and large multi-family residential properties access to low-cost, long-term loans to conduct energy efficiency and water conservation improvements to real property. Since the establishment of the PACE Act in Texas, over 35 counties and cities have implemented the program in their jurisdictions, resulting in 26 executed projects valued at over $100 million in loans.
San Antonio’s historic Travis Building will be undergoing a $5 million renovation for efficiency upgrades with support secured through the TX-PACE program. The upgrades will include reflective roofing, LED lighting, water-conserving plumbing modifications, and HVAC upgrades that will result in an estimated $8.4 million in energy cost savings over its lifespan. The building will ultimately house 63 multifamily units and keep its dedicated retail space on the ground floor. Renovations are expected to be complete in spring of 2022.
For any inquiries regarding PACE, please email Lyle Hufstetler lhufstetler@aacog.com with AACOG or Thomas Davis Thomas.Davis@sanantonio.gov with the City of San Antonio.
The Travis Building will see upgrades such as reflective roofing, LED lighting, water-conserving plumbing modifications, and HVAC upgrades.

Every Little Bit Helps! Make Your Home or Building Greener!
We all need to play a role in using our natural resources more selectively. By developing our buildings and infrastructure to still perform the way we want them to while using less fuel, water, and other resources, we are making strides in the right direction. Learn more about how you can do more with less.
Better Living
Household Energy Burden
In addition to building better structures, we need to work on reducing energy use in existing buildings, including across the many homes in our community.
The portion of household income that is spent on energy takes away from available spending on other necessities and investments that could otherwise be used to live a happy and sustainable life.
On average, San Antonio households spent 3% of their income on energy. Those earning less put a much higher proportion of their income towards energy costs. Households with a "high energy burden" spend over 6% of their income on energy. 22% of San Antonio households meet that level. Even worse, there are over 88,000 households in San Antonio with a severe energy burden in excess of 10% of income.
When we invest in energy efficiency in our community, it is not only to protect the climate, but also to build a more financially resilient community.

Our situation got a whole lot better...I'm very grateful
The Maldonado Family saved hundreds of dollars on their CPS Energy bill while making their home energy efficient.
