Presentation Transcript

  1. Request for Generation Data from ISO-NE • Chris Nelson - CT DEP • NEPOOL Markets Committee Meeting • October 12, 2004 • chris.nelson@po.state.ct.us • (860) 424-3454

  2. Data Request Summary • On behalf of all ISO-NE states, CT has requested unit-level net generation data for the entire ISO-NE region for the years 2000-2002. • Data has been requested on a monthly basis so that both annual and ozone season (May – Sept) totals can be compiled.

  3. Programmatic Uses of Data • To facilitate output-based allowance allocations under cap-and-trade emissions reduction programs such as the NOx Budget Program (NBP) and the pending Regional Greenhouse Gas Initiative (RGGI). • To allocate allowances to qualifying renewable energy projects from established set-aside allowance pools.

  4. Cap-and-Trade Overview • Cap-and-Trade is a market-based policy tool for protecting human health and the environment. • How it works: • An emissions cap is set below current or historical emissions levels for the trading region. • A number of allowances (1 allowance for each ton of the cap size) are allocated to affected units. • At end of compliance period, each affected unit must retire 1 allowance for each ton of the specified pollutant that it emits. True-up is conducted on an annual basis.

  5. OTC NOx Budget Program • Purpose was to reduce emission levels of NOx, an ozone precursor, during the 5-month ozone season. • Program applied to fossil fuel-fired electricity generating units (EGUs) ≥ 15 MW and large boilers ≥ 250 MMBtu/hr • In place 1999-2002

  6. OTC NOx Budget Program • Adopted by OTC States • CT, DC, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VT

  7. EPA NOx Budget Trading Program • Replaced and expanded OTC program in 2003 • OTC states only in 2003 • NOx caps tightened from 1999-2002 levels • Additional states added to program beginning in 2004: AL, IL, IN, KY, MI, NC, OH, SC, TN, VA, WV • GA, MO to be added in 2007

  8. Goal Design a regional cap-and-trade program initially covering CO2 emissions from fossil fuel-fired EGUs ≥ 25 MW (by April 2005).

  9. 9 Participant States • Maine, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, New York, New Jersey, Delaware • Observer States • Pennsylvania, Maryland, District of Columbia, Oregon, (California)

  10. Regional Statistics • 3rd Largest World Economy • 14% US GHG Emissions • 3.2% of World GHG Emissions ( Germany)

  11. RGGI Future Goals • Add States to Emissions Market • Add Offset Categories to Program Over Time • Possible Expansion to Smaller Electricity Generating Units • Possible Expansion to Major Stationary Sources in Other Sectors

  12. Allocation • Traditionally, allocation to affected units had been done on a heat input basis (EPA Acid Rain Program, OTC NOx Budget Program). • To better promote / reward higher efficiency, there has been a move toward output-based allocation using net generation data. ISO data is regarded to be of the highest quality and the best option for this purpose.

  13. NBP Allocation • Several states are using ozone season net generation data to allocate NOx Budget Program allowances to its units (e.g., allocations to CT NBP units in 2005 will be based on an average of the unit’s average OS generation for the two previous years). • States are also using generation data from renewable energy sources to distribute allowances from NOx set-aside pools.

  14. RGGI Allocation • RGGI states are evaluating allocation methodologies. The discrete block of net generation data requested will be used to: • prorate the regional cap to the state budget level • allocate the state budget to the unit level.

  15. Status of RGGI Data • RGGI needs to be a transparent process. All data compiled will be shared with stakeholders and other interested parties. Data for RGGI units is posted online and already contains generation data from other sources. • NY annual net generation data already posted online on NY ISO website. • NJ trying to get same data set from PJM for NJ, DE, PA, MD and DC.

  16. Future Data Needs • Monthly net generation will be required in future years for NOx Budget Program and RGGI programs. • If this data is not made publicly available by ISO-NE, states will be forced to include duplicative reporting requirements in their state regulations (i.e., “submit the same generation data that you submit to ISO-NE…”) • Official data set should reside in one location for the purpose of consistency.

  17. Other Uses for the Requested Data • In addition to the usefulness of the data for NOx Budget Program and RGGI purposes specified in this presentation, net generation output data is also valuable for several other objectives.

  18. Conclusion • Public release of ISO-NE historical net generation data would be useful for multiple purposes. • Releasing historical data does not skew future market prices, thus confidentiality should not be an issue. • Releasing the data will eliminate potentially duplicative reporting requirements for EGUs.
