This required that the analysis should include the integrated savings estimation from all projects projected through 2026 for both the annual and Ozone Season Period (OSP)1 NOx reductions. The year 2018 was used for the baseline year to estimate the emissions. The NOx emissions reductions from all these programs were calculated using estimated emissions factors for 2018 from the US Environmental Protection Agency (US EPA) eGRID database, which had been specially prepared for this purpose.Item The International Code-Compliant Calculator (IC3) v4.5.6(2022-10-19) Li, Qinbo; Baltazar, Juan-Carlos; Haberl, JeffItem Statewide 2021 Air Emissions Calculations From Wind and Other Renewables VOL II(2022-10-18) Baltazar, Juan-Carlos; Haberl, Jeff; Yazdani, Bahman; Li, Qinbo; Claridge, David; Azimi, Mitra; Ahn, Jounghwan; Sun, YuItem Statewide 2021 Air Emissions Calculations From Wind and Other Renewables VOL I(2022-10-18) Baltazar, Juan-Carlos; Haberl, Jeff; Yazdani, Bahman; Li, Qinbo; Claridge, David; Azimi, Mitra; Ahn, Jounghwan; Sun, YuItem A Survey of Urban-Scale Building Energy Modelers(2022-06) Zhao, Xi; Haberl, JeffItem Statewide 2020 Air Emission Calculations from Wind and Other Renewables VOL II(2022-02-27) Baltazar, Juan-Carlos; Haberl, Jeff; Yazdani, Bahman; Claridge, David; Azimi, Mitra; Ahn, Jounghwan; Sun, Yu; Li, QinboThe 79th Legislature, through Senate Bill 20, House Bill 2481 and House Bill 2129, amended Senate Bill 5 to enhance its effectiveness by adding 5,880 MW of generating capacity from renewable energy technologies by 2015 and 500 MW from non-wind renewables. This legislation also requires the Public Utilities Commission of Texas (PUCT) to establish a target of 10,000 megawatts of installed renewable capacity by 2025, and requires the Texas Commission on Environmental Quality (TCEQ) to develop methodology for computing emissions reductions from renewable energy initiatives and the associated credits. In this Legislation, the function of the Energy Systems Laboratory (ESL) is to assist the TCEQ in quantifying emissions reductions credits from energy efficiency and renewable energy programs, through a contract with the TCEQ to develop and annually calculate creditable emissions reductions from wind and other renewable energy resources for the State Implementation Plan (SIP). The ESL, in fulfillment of its responsibilities under this Legislation, submits the annual report, “Statewide Air Emissions Calculations from Wind and Other Renewables,” to the TCEQ. The report is organized in several deliverables: 1. A summary report, which details the key areas of work, 2. Volume I report, which includes the main document of renewable energy projects and 3. Volume II technical appendix that includes all information and details about renewables (i.e., wind power, non-utility scale and utility-scale solar PV, solar thermal, biomass, hydroelectric, geothermal, and landfill gas-fired) 4. Supporting data files, including weather data, and wind energy production data. This volume contains detailed data and analysis for each of wind and other renewables: • Analysis of wind power generation models, • Analysis of wind power degradation.Item Statewide 2020 Air Emission Calculations from Wind and Other Renewables VOL I(2022-02-27) Baltazar, Juan-Carlos; Haberl, Jeff; Yazdani, Bahman; Claridge, David; Azimi, Mitra; Ahn, Jounghwan; Sun, Yu; Li, QinboThe 79th Legislature, through Senate Bill 20, House Bill 2481 and House Bill 2129, amended Senate Bill 5 to enhance its effectiveness by adding 5,880 MW of generating capacity from renewable energy technologies by 2015 and 500 MW from non-wind renewables.

Table 1-1 lists the statutory mandates and total wind power generation capacity (including installed and announced) in Texas from 2001 to 2025. It shows that Texas has achieved its milestone of 10,000 MW by the end of 2010 and could reach total 42,284 MW by 2023 according to the information from PUCT1. By the end of 2020, the total installed capacity in Texas is 32,413 MW. In this Legislation, the function of the Energy Systems Laboratory (ESL) is to assist the TCEQ in quantifying emissions reductions credits from energy efficiency and renewable energy programs, through a contract with the TCEQ to develop and annually calculate creditable emissions reductions from wind and other renewable energy resources for the State Implementation Plan (SIP).
