  1. Electric Generation on High Electric Demand Days Tonalee Carlson Key New Jersey Dept. of Environmental Protection New Jersey Clean Air Council Annual Public Hearing April 1, 2009

  2. Overview • High Electric Demand Day Generation and Air Quality • The Regional Effort • The New Jersey Response • The Other Pieces of High Electric Demand Day Generation

  3. On High Electric Demand Days, NOx Emissions From EGUs Go Up High Electric Demand Day Generation and Air Quality :

  4. High Electric Demand Days Correspond with High Ozone Days

  5. The Mix Of Generating Units in Operation Varies By Day And Region

  6. Baseload Peakers - Peaking Units & Load Following Boilers NJ Electrical Generating Units Ozone Season Use 2005-07 Not all units run every day Percentage Operated During Ozone Season

  7. Fuel Types Comprising the Daily NOx Emissions sorted by NOx Mass from NJ & NYC EGUs June 1 - September 15, 2005 Source of high electric demand day NOx emissions is different throughout the OTR In New York City and New Jersey the source of NOx is primarily gas and diesel fired combustion turbines NOxEmission from Nj/NY EGUs (tons)

  8. Fuel Types Comprising the Daily NOx Emissions sorted by NOx Mass from New England EGUs June 1 - September 15, 2005 In New England the source is primarily residual oil fired load following boilers NOx Emission from New England EGUs (tons)

  9. Delta getting larger-- HEDD units have a more profound effect Baseload units are getting cleaner Baseload EGUs Getting CleanerBut Emissions on HEDD Remain High 623 1615 551 798 1349 Emissions for units In 6 States: CT,NY, NJ,PA,DE,MD

  10. The Air Quality Implications

  11. Facilities with High Electric Demand Day Units High Electric Demand Day UnitsAdjusted in the Sensitivity Modeling

  12. Maximum 8Hr Ozone Reductions (ppb) from High Electric Demand Day UnitsNOx = 0.1 lb/ mmBtu Modeling Episode- Aug 1-15, 2002

  13. The Regional Effort

  14. Process & Accomplishments • Over a year long, multiple meeting process (2006-2007) • Robust stakeholder process (RTOs, PUCs, Generating Co., EPA, State Staff) • Reductions formalized in OTC MOU

  15. The New Jersey Response: The High Electric Demand Day Rule Signed by Commissioner 3/20/09

  16. ImplementationTwo Phases • Short Term • Reductions from: 5/19/2009 – 9/30/2014 • Reductions to aid attainment of the 1997 8-hour ozone standard • Allow electric generating companies to develop and implement long term strategy to meet 2015 performance standards • Based on OTC MOU (NJ committed to 19.8 TPHEDD reductions relative to the 7/26/05 base HEDD) • Applies to each HEDD unit that: • For CTs: not controlled by water injection or SCR • For boilers: not controlled by SCR or SNCR • For all: had NOx emission rate of ≥ 0.15 lbs/MMBTU

  17. Implementation - Short Term - continued • The owner or operator will prepare a 2009 HEDD Emission Reduction Compliance Demonstration Protocol • Applicable measures to obtain required emission reductions: • Control the HEDD unit • Reduction in HEDD unit usage • Control non-HEDD unit • For duel fueled: combust NG on HEDD • Implement: • energy efficiency measures • demand response measures • renewable energy measures • Other measures approved by the Department Units in NJ, PA, DE or MD

  18. Implementation - Long Term - continued • Long Term • Performance standards applicable 5/1/2015: • Estimated emission reductions in 2015: 64 TPD (relative to the 7/26/05 base HEDD)

  19. Rule Status • Rule Status: • Final Rule Published in NJ Register: April 20, 2009 • Operative Date: May 19, 2009 • Final Rule Document: (after April 20th) http://www.nj.gov/dep/rules/adoptions.html • Regional Record: http://www.otcair.org/document.asp?fview=meeting

  20. The Other Pieces of High Electric Demand Day Generation

  21. RegionalTransmissionOrganizations (3) • ISO-NE, NYISO, PJM • Taught us about alerts, electricity distribution, pricing of electricity, demand response, and capacity payments • PublicUtilityCommissions • Taught us about energy planning-goals-requirements at the state level • In NJ: Energy Master Plan was being developed • Generators • The parties that operate daily under the requirements of all three organizations – environmental, PUC, RTO • ‘Reality’ glue
