Latest data on top 100 power producers show declining SO2, NOx and CO2 emissions and increasing use of energy efficiency and renewables

BOSTON, Jul. 31 /CSRwire/ - A new report on U.S. power plant emissions from the top 100 power producers demonstrates the impact of the electric power industry’s current transition to cleaner energy sources.
The 2012 Benchmarking Air Emissions report is the eighth report in a series highlighting environmental performance and progress in the nation’s electric power sector. The report is based on 2010 generation and emissions data from the Energy Information Administration and the Environmental Protection Agency, and also includes analysis of preliminary 2011 emissions data. The previous edition reported on 2008 data.
Key findings of the report include:
Using preliminary sector-wide emissions data from 2011, the report indicates a continued downward trend in CO2 emissions, with emissions falling an additional five percent compared to 2010. Emissions of CO2 had increased by about five percent from 2009 to 2010 as demand for electricity increased with the recovering economy. However, CO2 emissions declined by a similar amount from 2010 to 2011 due to a shift away from coal-fired generation. Preliminary data also indicate that in 2011, sector-wide power plant SO2 and NOx emissions continued to fall, dropping 40 percent and 35 percent below 2008 levels, respectively. Emissions of these pollutants are expected to decline further as power plant owners install additional pollution controls and plan to retire roughly 12 percent of the nation’s coal-burning fleet.
“This is an historic transition for the electric power industry,” said Mindy Lubber, president of Ceres, which prepared the report with M.J. Bradley & Associates, NRDC, Entergy, Exelon, Tenaska and Bank of America. “More and more power producers are shifting away from coal-fired generation in favor of lower-emitting natural gas-fired plants, renewable power and energy efficiency. The economic case for cleaner energy is better than it’s ever been, and this report shows that the industry is adapting to stronger Clean Air Act emissions standards, state-driven efficiency and renewable energy incentives and the dynamics of the current natural gas market.”
“Business and policy decisions are only as good as the information on which they’re based. The report fills the need for impartial analysis and is instructive, highlighting the wide variety of energy emission rates due to advancement in technology over time, differing fuel types, and a shift to cleaner energy portfolios,” said Greg Kunkel, Tenaska vice president of environmental affairs.
The widespread transition away from coal is affecting some of the nation’s largest coal burners, the report finds. For example, Southern Company, one of the nation’s most coal-intensive power producers, expects its fuel mix to include more natural gas than coal in 2012 for the first time in its 100-year history. American Electric Power, the biggest producer of electricity, said in April that it used 62 percent more gas in the first three months of the year than it did in 2011.
Since January 2010, power plant owners have announced about 40 gigawatts of coal plant retirements, representing approximately 12 percent of the nation’s coal-fired capacity. Most of the plant closures are scheduled to occur between 2012 and 2020, and some already have occurred. The plants set for closure are largely older, smaller and higher polluting, the report finds. At the same time, natural gas consumption by the electric power sector has increased at an average rate of 4 percent per year over the past decade.
Changes in the generating fleets of Tennessee Valley Authority (TVA) and Xcel Energy are indicative of these broad trends in the electric power sector. From 2008 to 2010, TVA reduced its proportion of coal-generated electricity from 61 percent to 52 percent of overall generation and achieved significant reductions in SO2, NOx and CO2 emissions rates across all generating sources. Similarly, changes to Xcel Energy’s generating resources resulted in significant reductions in the utility’s fleet-wide emissions rates from 2008 to 2010. Most recently, Xcel reported that more than 50 percent of its total Colorado load was served by wind at one point in early 2012, and California’s three investor-owned utilities—Pacific Gas and Electric, Southern California Edison, and San Diego Gas & Electric—exceeded 20 percent renewable generation at the end of 2011.
“This report underscores the tremendous progress we are making in cleaning up our air, improving our health and moving America toward a more prosperous and more advanced energy economy. But the report also serves as a reminder that we still have a long way to go and that some companies have farther to go than others. It's time to redouble our efforts," said Dan Lashof, Program Director of Climate and Clean Air at the Natural Resources Defense Council.
Benchmarking Air Emissions also shows zero-emitting technologies gaining ground. In 2011, the U.S. wind energy industry added over 6,800 megawatts (MW) of new wind power capacity, bringing the nation’s cumulative total to over 47,000 MW. High wind capacity in Texas, Colorado, and the Upper Midwest has led to record high contributions by wind to the total energy mix.
In addition, energy efficiency is competing with generation resources in the nation’s largest electricity markets. In PJM Interconnection, the largest wholesale electricity market in the world, 900 MW of energy efficiency cleared the latest auction. Nationally, utility efficiency budgets have increased 26 percent from $5.4 billion in 2010 to $6.8 billion in 2011.
Benchmarking Air Emissions presents comparative analysis of emissions data for 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.

In addition to the aggregate corporate emissions data for 2010 provided in this report, company-specific data for 2010 are now available for download at mjbradley.com.
