New Report Reveals States and Utilities with Highest and Lowest Power Plant Emissions; Overall U.S. Emissions Decline

Latest data on top 100 power producers show significant declines in SO2, NOx and moderate CO2 reductions

BOSTON, May 15 /CSRwire/ - A major new report on U.S. power plant emissions from the top 100 power producers shows that the electric industry cut emissions of NOx, SO2 and CO2 in 2011 even as overall electricity generation increased, largely due to increased use of natural gas and growing reliance on renewable energy.

Based on the latest available data, the report also reveals that Wyoming, Kentucky, West Virginia, Indiana, and North Dakota had the highest CO2 emissions per megawatt-hour of power produced, while Idaho, Vermont, Washington, Oregon, and Maine had the lowest CO2 emissions rates. Nationwide, five power producers—American Electric Power, Duke Energy, FirstEnergy, Southern Company, and Tennessee Valley Authority—generate 25 percent of overall electric sector CO2 emissions, though some of these producers and others have significantly reduced emissions in recent years.

The Benchmarking Air Emissions report is the ninth in a series highlighting environmental performance and progress in the nation’s electric power sector. Traditionally, the report has been published every two years. However, in light of ongoing changes within the industry, in terms of plant retirements, pollution control retrofits and new emissions regulations under consideration, a streamlined version of the report was prepared this year, based on 2011 generation and emissions data from the Energy Information Administration and the Environmental Protection Agency.

Key findings of the report include:

  • In 2011, power plant NOx and SO2 emissions were 70 percent and 72 percent lower, respectively, than they were in 1990 when Congress passed major amendments to the Clean Air Act.
  • Since 1990, power plant CO2 emissions CO2_Sourceshave increased by 20 percent, although CO2 emissions declined 7 percent from 2008 through 2011.
  • There is wide variation in CO2 emission rates across the 50 states, as noted in the report’s new state-by-state emissions summary. States with the highest CO2 emission rates were heavily reliant on coal: Wyoming and Kentucky, the states with the highest CO2 emission rates, relied on coal for 86 and 93 percent of their power generation, respectively.
  • Coal accounted for 44 percent of the power produced by the 100 largest companies in 2011, followed by natural gas (23 percent), nuclear (22 percent), hydroelectric power (8 percent), non-hydroelectric renewables and other fuel sources (3 and 1 percent, respectively), and oil (less than 0.2 percent).
  • From 2000 to 2011, natural gas generation increased 69 percent industry-wide, while renewable generation increased 44 percent. Coal-fired generation dropped 12 percent over the same period.

“The electric power industry is moving to cleaner sources of energy, demonstrating that cleaner power generation is achievable. Stronger regulations will reinforce those trends and stimulate further investment in low-carbon, low-risk resources like renewable power and energy efficiency,” said Mindy Lubber, president of Ceres, which sponsored the report with NRDC, Entergy Corporation, Exelon, Pacific Gas and Electric Company, PSEG, Tenaska and Bank of America. M.J. Bradley & Associates authored the report.

“The Benchmarking Air Emissions report is an important resource for following changes in the U.S. electric power sector,” said Chuck Barlow, Vice President, Environmental Strategy and Policy for Entergy Corporation. “The rise of natural gas is a game-changer for U.S. power plant emissions, as this year’s analysis shows. At Entergy, our focus has long been on providing value to all of our stakeholders while maintaining our commitment to environmentally responsible action. A diverse generation portfolio helps us get there.”

Each edition of the Benchmarking Air Emissions report analyzes the latest emissions from the 100 largest power producers in the U.S. In 2011, the year covered in this edition of the report, the top 100 power producers together accounted for 86 percent of the electricity produced. The 100 largest power producers emitted approximately 4.1 million tons of SO2, 1.7 million tons of NOx, 25 tons of mercury, and 2.1 billion tons of CO2 in aggregate during 2011.

Air pollution emissions from power plants, while declining overall, are highly concentrated among a small number of power producers. For example, nearly a quarter of the electric power industry’s SO2 and CO2 emissions come from just three and five top producers, respectively, as illustrated in summary slides available for download at mjbradley.com/benchmarking-air-emissions.

The report also provides company-specific emissions trend information from 2000 through 2011 for the four largest power generators, illustrating the range of approaches that power companies have used to reduce emissions:

  • AEP reduced its total SO2 emissions by 52 percent between 2000 and 2011, from 1.1 million tons to just over half a million tons, primarily by adding scrubbers to approximately 7,900 megawatts of coal-fired generating capacity.
  • Southern Company reduced total SO2 emissions by 63 percent while increasing overall generation by 8 percent between 2000 and 2011 by bringing online approximately 14,000 megawatts of natural gas-fired capacity during the same period.
  • NextEra Energy added more than 20,000 megawatts of wind, solar, and natural gas-fired generating capacity between 2000 and 2011, and nearly doubled its total power generation, driving down its CO2 emissions rate from 1,023 to 603 pounds per megawatt hour, a 41 percent improvement.
  • Among the top 100 power producers, Exelon had the eighth lowest CO2 emissions rate in 2011, largely due to its large nuclear and renewable energy fleet, as well as its investments in nuclear uprates. Even with a low level of emissions, Exelon reduced its total CO2 emissions by 32 percent and its CO2 emission rate by 40 percent between 2000 and 2011.

“Power plants are America’s largest source of global warming pollution. The good news is that their emissions have declined significantly since their peak in 2007, but we still have a long way to go. The Benchmarking Report provides a valuable scorecard, allowing citizens and policymakers to compare the performance of individual companies against others in this critical industry," said Dan Lashof, Program Director of Climate and Clean Air at the Natural Resources Defense Council.

“Today’s report highlights the credit due to policy leaders in New Jersey and at the federal level for adopting policies that have reduced power plant emissions. The progress made in New Jersey can, and should, be a model for policymakers across the country,” said Geraldine Smith, PSEG’s General Environmental Counsel and Managing Director Environmental Policy. “By investing more than $3 billion in our New Jersey power plants since 2005, PSEG has been able to reduce emissions of NOx, SO2 and mercury by more than 90 percent, while increasing output of electricity. We look forward to participating in future discussions on cost-effective ways to improve air quality in our home state and across the nation.”

The 2013 Benchmarking Air Emissions report’s comparative analysis of emissions data is relevant to policymakers considering regulatory approaches; public interest organizations concerned about public health and consumer costs; and financial analysts and investors assessing company risk exposure as power plant emission limits in the U.S. gain more momentum.
