NOTICE OF COMMITTEE WORKSHOP

 

Committee Workshop on the Potential Need for
Emission Reduction Credits in the South Coast
Air Quality Management District

The Energy Commission's Integrated Energy Policy Report (IEPR) Committee will conduct a workshop to discuss the potential need for new and replacement generation in areas under the jurisdiction of the South Coast Air Quality Management District in order to meet state policy directives and local reliability needs. This need translates into a need for particulate matter 10 microns or less in size (PM-10) air emission credits, whose purchase or provision is currently constrained by both market conditions and litigation, thus precluding the development of new and replacement generation that produces such emissions. Commissioner Jeffrey D. Byron is the Presiding Member of the 2009 IEPR Committee, and Vice Chair James D. Boyd is the Associate Member. Other Commissioners may also attend and participate in this workshop. The workshop will be held:

THURSDAY, SEPTEMBER 24, 2009

Purpose and Background

The area under the jurisdiction of the South Coast Air Quality Management District (SCAQMD) includes two transmission-constrained areas that require substantial amounts of dispatchable, local electric generation capacity: the California Independent System Operator portion of the Los Angeles Basin and the control area of the Los Angeles Department of Water and Power. Limits on the ability to import power into these areas require that threshold amounts of capacity be located in these areas to meet reliability standards imposed by the North American Electric Reliability Corporation.

More than 8,000 MW of generation capacity in the Los Angeles Basin may be facing retirement during the coming decade. The existing generation fleet in the Los Angeles Basin includes more than 7,000 MW of capacity at ten facilities that are more than 30 years old and were identified as candidates for retirement in the 2005 and 2007 IEPRs. In June 2009, the State Water Resources Control Board issued a draft policy on the use of ocean water for power plant cooling, which effectively requires generation units using once-through cooling (OTC) to undertake substantial investment, which means refitting their cooling systems or repowering, or to retire. This affects more than 7,000 MW at six of the ten facilities. Investments in energy efficiency, demand response, renewable resources, and transmission upgrades within the Los Angeles Basin will contribute to meeting local capacity requirements or reduce them. This will allow a share of OTC plants to be retired, and replaced with resources outside the Los Angeles basin if necessary. But the remaining capacity will continue to be required within the basin. As refitting is likely to be technologically infeasible or uneconomic at many, if not most locations, this will require repowering or retirement and replacement with gas-fired generation, both of which will require air emission credits from SCAQMD.

The ability of generators to secure PM-10 emission reduction credits (ERCs) or offsets in SCAQMD is severely constrained by both market conditions and litigation that precludes SCAQMD from issuing offsets from its own accounts. SCAQMD reports that prices in the PM-10 market have increased to as much as $140,000/lb/day, which would add $100 million-$200 million to the cost of power plant development if sufficient ERCs were available. Trading during 2008 indicates, however, that less than 1,000 pounds are available through the open market; replacing even half the capacity in the Los Angeles Basin that is aging or uses OTC with gas-fired resources would require perhaps five times as many ERCs as are apparently available. Litigation currently precludes SCAQMD from providing offsets under exemptions to its Rule 1304, which has allowed for such provision when power plants are repowered or replaced, and from its Priority Reserve, opened to new power plants in 2007.

Various pieces of legislation that would provide credits to new and existing power plants have been proposed to date. The legislation ultimately enacted may provide credits for new plants or only provide offsets to existing power plants for the purpose of repowering or replacement, or both. It is possible that legislation will not successfully address the potential longer-term need for repowering and replacement in the Los Angeles Basin.

Issues for Discussion

The following topics will be discussed at the workshop:

  1. What is the current and near-term supply-demand balance in both Southern California and the transmission-constrained areas within SCAQMD jurisdiction? Are reserves sufficient to ensure reliability? What are the implications of air emission credit issues for power plants currently under development?
  2. While the current impasse of air credits focuses on PM-10, there are plans to create a separate and distinct particulate matter less than 2.5 microns in size (PM-2.5) standard, which would likely be the focus of emission compliance issues for power plants. How will California Air Resources Board (CARB) and the district address changes in their permitting processes if a separate PM-2.5 standard is put in place? When should such a change be considered likely to occur? Are there other criteria pollutants that are significant to power plant licensing that the energy agencies should be aware of over the next 10 years or so?
  3. What are current conditions in the PM-10 credit market and the status and impact of litigation that has restricted the availability of PM-10 offsets from SCAQMD accounts? What are the likely timelines for action by the air district given the passage or rejection of proposed legislation?
  4. What are the potential PM-10 ERC needs in the California ISO portion of the Los Angeles Basin during the next five to ten years? How much in-basin gas-fired capacity is likely to be needed to meet local reliability needs? How often is it likely to be dispatched and what are the implications of its operating profile for ERC needs?
  5. What are the potential PM-10 ERC needs of the Los Angeles Department of Water and Power?
  6. How are PM-10 ERC requirements for individual power plants determined by SCAQMD? How do District rules and policies impact the determination of a plant's PM-10 liability and comport with the lbs/mmscf limit that typically becomes part of the Permit to Operate? How does the relationship between ERC requirements and maximum operation in summer months in SCAQMD compare to that in other air districts?
  7. One potential solution to the current impasse involves establishing a fixed amount of emissions for new power plants from which credit-satisfying permit requirements could be provided to supplement those from market sources. If this mechanism were put in place, how should scarce credits be allocated among competing projects?
  8. PM-10 ERC needs for given amounts of generation capacity can be reduced by limiting the maximum monthly fuel throughput along with output of resources needed primarily for reserves. In the course of applying for air permits, what considerations enter into developer/utility proposals for limits on hourly and monthly and annual emissions? For monthly and annual emissions, can these limits be reduced without disadvantaging projects in competing for utility contracts or reducing contributions to resource adequacy requirements? If so, what, if any mechanism would be needed to handle force majeure events that threatened reliability?
  9. Other issues raised by participants.
