Overview of Environmental Performance of Power Plants in Texas

  1. 1. Overview of Environmental Performance of Power Plants in Texas May 2010 Legislative advertising paid for by: John W. Fainter, Jr. • President and CEO Association of Electric Companies of Texas, Inc. 1005 Congress, Suite 600 • Austin, TX 78701 • phone 512-474-6725 • fax 512-474-9670 • www.aect.net
  2. 2. AECT Principles • AECT is an advocacy group composed of member companies committed to: - Ensuring a modern, reliable infrastructure for the supply & delivery of electricity. - Supporting efficient competitive markets that are fair to customers and market participants. - Supporting consistent and predictable oversight and regulation that will promote investment and ensure the stability of Texas’ electric industry. - Promoting an economically strong and environmentally healthy future for Texas, including conservation and efficient use of available resources. • AECT member companies remain dedicated to providing Texas customers with reliable service and are committed to the highest standards of integrity. The Association of Electric Companies of Texas, Inc. (AECT) is a trade organization of investor- owned electric companies in Texas. Organized in 1978, AECT provides a forum for member company representatives to exchange information about public policy, and to communicate with government officials and the public.

  3. 3. CO2 Emissions in Context of Texas’ Economy A common refrain is that CO2 emissions generated in Texas are higher than in other states. However, it is critical to view that in the context of other truths: − Texas generates more electricity than any other state; in fact, Texas produces almost 80% more electricity than the next most generating state.1 − Much of the CO2 emitted in Texas results from the generation of “products” that are very significant to our state and nation. For example, Texas produces about: − 60% of petrochemicals produced in the U.S. − 30% of gasoline and diesel refined in the U.S. − 10% of electricity generated in the U.S. − The dollars of gross product produced in Texas per ton of CO2 emitted is high, and it increased by more than 1000% between 1963 and 2001. − The ratio of the amount of CO2 emitted per MWh of electricity generated in Texas is lower than half of the states that have more than a nominal amount of coal-fired or oil- fired electricity generation (see previous slide). 1 3 Source: EIA, 2008 State Electricity Profiles

  5. 5. Texas Is Already Leading the Way in Clean Power Plants Texas has the largest emissions of any state since it produces ~80% more power than the next ranked state. 0.247 0.395 OK 0.223 NM AR 0.156 0.103 LA TX 2008 NOx Emission Rate Averages Area (lbs/mmBtu) National 0.222 Over 80% of the fossil-fueled electricity produced in Texas Texas 0.103 comes from East Texas.

  12. 12. Additional Emission Reductions  Federal Clean Air Interstate Rules (CAIR) − Requires additional NOx and SO2 emissions reductions from power plants in 2009, 2010, and again in 2015, with a cap and trade program. − The NOx and SO2 emissions from all new units must “fit” under the 2009, 2010, and 2015 caps; such emissions are not in addition to those caps. − TCEQ has recently revised its rules to implement CAIR.  Regional Haze − Requires reductions in NOx, SO2, and Particulate Matter (PM) emissions based on best available retrofit technology (BART) for different types of facilities, including electric generating units, industrial boilers, and refineries. − EPA has decided that NOx and SO2 emissions reductions made for CAIR will suffice for the NOx and SO2 emissions reduction requirements under Regional Haze. − The TCEQ is developing rules to implement BART. 12
