  2. Presentation Overview • Introduction • Mission of GATS Working Group • Critical Issues • Areas of agreement • Areas of disagreement • Other Challenges • Lessons Learned

  3. Introduction • PJM initiated the GATS project in response to state commission inquiries. • Fuel mix and emissions disclosure – NJ, DE, MD; PA on request of customer • Renewable portfolio standards – NJ • Emissions portfolio standards – contemplated by NJ • The GATS Working Group is attempting to come to a consensus on a proposal to present to the PJM Energy Markets Committee in May 2003. • The goal is to create a system that is flexible enough to meet varying and evolving state requirements.

  4. GATS Working Group Mission To recommend to the PJM Energy Markets Committee a single information system that will support reporting, compliance, and verification requirements related to environmental attributes of electric generation. Such a system should: Ensure accurate accounting and reporting, facilitate efficient and transparent transactions among market participants, provide flexibility to accommodate varied and changing state policies or programs, maintain liquidity in the energy market, mitigate seams issues, and be cost effective.

  5. Terminology • A “Certificate” is defined by the GATS Working Group as all attributes associated with each MWh, whether the attributes are traded or not traded, whether the attributes are “bundled” or “unbundled”. • An “attribute” is a characteristic of a generator, such as location, emissions output, fuel mix, etc.

  6. Critical Issues • Areas of Agreement: • GATS will collect information on all generation resources, all MWhrs produced, and all load served within the PJM region. • GATS will use the PJM market settlement database in combination with generator fuel mix and emission information. • A certificate will be created for every MWh generated to allow for maximum flexibility of the system. • GATS will be capable of “unbundling” certificates from all MWhrs and tracking them separately. Generator information will be tracked whether “unbundled” or “bundled”. • Each certificate will have a unique serial number, and each certificate would be able to be held in only one entity’s account at a time to eliminate the possibility of double counting of the certificates.

  7. Critical Issues • Areas of Agreement: • GATS will provide a bulletin board where market participants can voluntarily post offers and bids for certificates. • The system will accommodate different products at the retail level • Retail suppliers will be permitted to set up different accounts within the system for each product offering, each state served, etc. • Renewable certificate sales to end-use customers will be permitted

  8. Critical Issues • Areas of Disagreement: • Certificate Lifespan – should certificates expire? • Some say yes, they have to in order to ensure they are not double counted and to coincide with the idea that MWhrs are consumed and cannot be stored. • Others say no, that there is no reason to retire them. The system is a database and the data does not go away, it is always in the system and should be allowed to be used for purposes outside of state disclosure/RPS requirements. • Residual Mix • What is it? (at the end of the settlement period, unsold certificates are pooled and averaged; this average is called the residual mix) • Who should calculate it? • How should it be calculated? • How should residual mix certificates be allocated?

  9. Other Challenges • State Reporting Requirements: • State reporting requirements for disclosure and RPS compliance may dictate the useful life of generator certificates. • In the New England GIS, quarterly settlement periods were selected to meet the needs of the state with the shortest compliance reporting requirements. • Renewable resources, which often have intermittent and seasonal production, would benefit by a longer settlement period (e.g., annual). • Cost allocation • Who pays? • Imports/Exports

  10. Lessons Learned • Well balanced stakeholder process is important • State regulators are critical; Beneficial if the states involved can agree on an approach • Market participants are also critical • Difficult to get people to leave their preconceived ideas about what the system should look like at the door • The issues are complex and it is a challenge to communicate clearly and affectively • Need a good set of terms/definitions • Having the right resources to run the stakeholder process is critical • Facilitation • Expert Consultants • Chair
