1 1 Environmental Leadership The Pursuit of Cleaner Air A Presentation to the DENR/DAQ Mercury and CO 2 Workshop Ben White April 20, 2004

2 2 Agenda Overview of Progress Energy Progress Energys Innovative Solutions for NOx Reduction Progress Energys activities pursuant to the Clean Smokestacks Act

3 3 Progress Energy at a Glance Super-regional energy company with over 23,000 megawatts of generation capacity Among the nations top ten utilities when ranked by generation capacity Employees: approximately 16,000 Customers: 2.8 million electric customers in North and South Carolina and Florida

4 4 Progress Energy at a Glance 2002 Generation Capability (MWs) 38 plant sites

5 5 NO X VOC SO 4 NO X VOC O3O3 O3O3 NO X NO 3 Air Pollutant Formation SO 2 NH 3 VOC OCOC PM 2.5

6 Triangle Area NOx Emissions 2007 Triangle Area NOx Emissions (Projected ) 2000 total NOx, Triangle area: tons per day Average summer weekday 2007 total NOx, Triangle area: tons per day Average summer weekday

7 7 Evolution of PGN NOx Control Technology Installations 1993 – 1999 Traditional approach (LNB/OFA) WIR installations st ROFA installation AEFLGR installation st ROFA/Rotamix installation st SCR installation additional SCRs in service

8 8 Progress Energy NOx Reduction Leadership Searched worldwide for emissions reduction technologies –Sweden – ROFA technology. Reduced NOx emissions by more than 50% at Cape Fear Plant. –Eastern Europe – WIR technology. Reduced NOx emissions by 35 to 40 percent at Weatherspoon and Lee plants. –First utility in the world to apply these controls Selective Catalytic Reduction (SCR) –First SCR in North Carolina - Roxboro Unit 4 –Three SCRs in-service in Person County on May 1, one year ahead of compliance requirements

9 9 NC Annual and Ozone Season NO X Emissions ActualProjected 77% reduction by 2007

10 10 Clean Smokestacks Act On June 20, 2002, North Carolina Senate Bill 1078, also known as the Clean Smokestacks Act, was signed into effect. This law, which was a landmark, cooperative effort between utilities, regulators, and environmental groups, requires significant reductions in the emissions of nitrogen oxides (NOx) and sulfur dioxide (SO 2 ) from utility owned coal-fired power plants located in North Carolina. This act is serving as a model that other states are following.

11 11 Progress Energy Emissions Reduction Leadership Clean Smokestacks –Broad coalition (DENR, Governor, General Assembly, Advocates, Utilities) –Technologies will be installed by 2013 –First scrubber operational in 2005 at Asheville plant –Rates frozen until 2007 –Investing more than $800 million to comply with Acts requirements –Investment in addition to the $370 million the company has spent to reduce NOx emissions in the ozone season –Technologies projected to reduce SO2 emissions by 74 percent and NOx emissions by 56 percent from 2001 levels –EPA Clean Air Excellence Award to state and its partners

12 12 Progress Energy owns and operates 18 coal-fired boilers at seven plants in North Carolina, with over 5000 MWe generating capacity. On June 20, 2002 Governor Easley signed into law SB1078 which caps emissions of nitrogen oxides (NOx) and sulfur dioxide (SO 2 ) from utility owned coal-fired power plants located in North Carolina. Progress Energy emissions caps for NC are: Tonnage Caps* NOx (2007) 25,000 SO 2 (2009) 100,000 (2013) 50,000 * Cumulative for all Progress Energy NC units Progress Energys Clean Smokestacks Act Plan Supplement April 1, 2004

13 13 Locations of Progress Energys Coal-Fired Power Plants in North Carolina

14 14 Progress Energy NO X Emissions (Annual Emissions in Tons) ActualSIP Call Clean Smokestacks

15 15 How Does an SO 2 Scrubber Work? A slurry of finely ground limestone (CaC0 3 ) is sprayed into a reaction tower, which has flue-gas flowing counter-current to the spray. The SO 2 in the gas reacts with the limestone, removing 95% of the S0 2 and making CaS0 4 (gypsum).
