Energy Efficiency/Renewable Energy Impact in the Texas Emissions Reduction Plan (TERP), Preliminary Report: Integrated NOx Emissions Savings from EE/RE Programs Statewide

Abstract

The Energy Systems Laboratory (ESL), at the Texas Engineering Experiment Station of the Texas A&M University System, in fulfillment of its responsibilities under Texas Health and Safety Code Ann. 388.003 (e), Vernon Supp. 2002, submits this sixth annual report, ‘Energy Efficiency/Renewable Energy (EE/RE) Impact in the Texas Emissions Reduction Plan (Preliminary Report)’ to the Texas Commission on Environmental Quality. In this preliminary report the NOx emissions savings from the energy-efficiency programs from multiple Texas State Agencies working under Senate Bill 5 and Senate Bill 7 in a uniform format to allow the TECQ to consider the combined savings for Texas’ State Implementation Plan (SIP) planning purposes. This required that the analysis should include the cumulative savings estimates from all projects projected through 2020 for both the annual and Ozone Season Day (OSD) NOx reductions. The NOx emissions reduction from all these programs were calculated using estimated emissions factors for 2007 from the US Environmental Protection Agency (US EPA) eGRID database, which had been specially prepared for this purpose. In 2007 the cumulative total annual electricity savings from all programs is 12,591,561 MWh/yr (8,326 tons-NOx/year). The total cumulative OSD electricity savings from all programs is 37,421 MWh/day, which would be a 1,559 MW average hourly load reduction during the OSD period (25.05 tons-NOx/day). By 2013 the total cumulative annual electricity savings from will be 28,802,074 MWh/year (18,723 tons-NOx/year). The total cumulative OSD electricity savings from all programs will be 88,560 MWh/day, which would be 3,690 MW average hourly load reduction during the OSD period (58.47 tons-NOx/day).
