NOx Emissions Reduction from CPS Energy's 'Save For Tomorrow Energy Plan' Within the Alamo Area Council of Governments Report to the Texas Commission on Environmental Quality

摘要

ESL used the Texas Commission on Environmental Quality?s (TCEQ) Guide for Incorporating Energy Efficiency/Renewable Energy (EE/RE) Projects into the SIP for local entities dated February 6, 2004 to survey potential projects in the AACOG area that occurred after the State?s base period (September 1, 2001) for their local Clean Air Plan.CPS Energy retained Nexant, Inc. (Nexant) to conduct a comprehensive, independent measurement and verification (M&V) evaluation of CPS Energy?s 2009 DSM programs. Nexant surveyed the energy and demand savings achieved by CPS Energy?s 2009 DSM programs. In 2009, the programs offered by CPS Energy had two sectors: residential and non-residential (commercial).To determine net program impacts, Nexant conducted market research of evaluations for other utility-sponsored DSM programs around the country. From the survey conducted in 2009, total net energy and demand savings from the residential and non-residential sectors are 86,712,978 kWh (residential subtotal is 62,369,566 kWh and non-residential subtotal is 24,343,412 kWh).Nexant calculated CPS Energy?s DSM potential through 2020 and found there to be significant room for program growth. Total cumulative achievable savings through the 2020 program year are expected to be 2,543 GWh of electricity savings (based on the aggressive incentive scenario and exception of industrial sector).According to the TCEQ/ESL, the total annual NOx emissions reductions estimated through 2009 energy savings were 114.03 ton/year. Annual NOx emissions reductions of residential sector were 82.02 ton/yr and annual NOx emissions reductions of non-residential sector were 32.01 Ton/yr.The NOx emissions reductions estimated through 2020 energy savings potential were 3,344 ton/year. Annual NOx emissions reductions of residential sector were 1,873 ton/yr and annual NOx emissions reductions of non-residential sector, except of industrial sector, were 1,471 ton/yr.
