The City of San Antonio and CPS Energy have committed to replacing 25,000 High-Pressure Sodium lights with more energy efficient GreenStar LED lights manufactured in San Antonio as part of a New Energy Economy agreement. In June 2011, GreenStar announced that it would move its assembly facility and corporate headquarters from Boerne to Alamo Downs Business Park in San Antonio along with 35 jobs.
The replacement of these lights will result in annual energy savings of 5.1 megawatts, enough to power 1,595 homes per year. The energy savings will help the City and CPS Energy reach the Save for Tomorrow Energy Plan’s (STEP) goal of achieving 771 megawatts of energy savings by 2020.
Three major phases of the project have been defined and include:
Phase 1 – The replacement of 23,500 streetlights on major thoroughfares (i.e., West Commerce, Judson Rd., SW Military, Fredericksburg Rd., Stone Oak Parkway, Lockhill Selma, West Ave.) within the City limits
Phase 2 – The replacement of 1,500 streetlights within CPS’ Downtown Network System.
Phase 3 – The replacement of 922 street light poles within CPS’ Downtown Network System.
Phase 1 began on Monday, October 15th and is expected to take 18 months to complete. Phases 2 and 3 are slated to begin in the fall of 2013 and will take 6 months to complete. All installations will be performed by the current CPS Energy street light contractor, L. E. (Letter L, Letter E) Meyers.
The estimated cost of the project is $16.5 million which will be funded by savings in the City’s annual streetlight bill. The CPS LED Tariff that was approved by Council on September 20, 2012 resulted in an annual reduction in our streetlight bill of approximately $1.1 million.
During the first full year of implementation in FY 2014, the annual savings are projected to be $1,374,000 which exceeds the expected debt service of $837,000 for the initial year.
