Energy Efficiency Fund


On August 8, 2011 the City Council passed Ordinance 2011-08-18-0657, which established the Energy Efficiency Fund (EEF) to fund energy conservation projects in its facilities that reduce utility expenditures. The fund was designed to receive utility saving dollars from completed utility conservation projects as well as project incentives or rebates received from CPS Energy and SAWS. During the 2013 annual budget and in order to expand the funding available for additional utility conservation projects, City Council adopted a mechanism to return utility savings and incentive or rebate dollars from utility conservation projects funded by the EEF back to the EEF. This action represents a long-term commitment by the City to pursue energy conservation. All current and future projects as well as associated personnel costs are funded out of the EEF without incurring debt. This method has effectively turned a one-time influx of grant funds into a permanent source of revenue for energy projects. San Antonio is the only city in the State of Texas with such a fund in place and is one of only a handful in the country to utilize this model.

Energy Efficiency Fund is used to Implement Energy Projects. COSA Realizes Utility Savings and Appropriate Savings and Rebates are returned to Energy Efficiency Fund.

Energy Projects

The Energy Efficiency Fund has completed 372 energy projects within 159 municipal facilities from FY11 through FY17, which has resulted in total cumulative avoided costs of $1.39M. The total appropriated amount used to implement these projects was $3.1M. From FY11 through FY17 the EEF has received over $2.94M in CPS Energy rebates and has received (“recaptured”) $4.13M in revenue from various City funding sources (General, HOT/CSEF/Cultural Affairs, Facility Services, Fleet Services and Parking).
