12. North American Energy Standards BoardGas Electric Interdependency – June 2005 Report Gas- Electric Interdependency Issues – Categories • Issue Categories: • Policy directions from regulatory agencies, contractual issues • Standards development by NERC • Standards development by NAESB • Regional issues • Infrastructure Concerns Prepared by the North American Energy Standards Board

13. North American Energy Standards BoardGas Electric Interdependency – June 2005 Report Gas- Electric Interdependency Issues – Characterized • 13 Issues Identified fall into the following groupings: • Communications issues between pipelines and generators • Risk assumptions in using interruptible transportation • Differences in timelines between markets • Need for regional or national solutions • Cost recovery and reserve capacity • Valuing and using short term capacity • Differences in curtailment policies in emergencies Prepared by the North American Energy Standards Board

14. North American Energy Standards BoardGas Electric Interdependency – June 2005 Report Gas- Electric Interdependency Issues – Report Conclusions • Conclusions Reached: • If the issues are to be addressed, the majority of them require a level of policy discussion prior to determining if standards are to be developed. • It is inherently difficult for parties to address these issues because of the difference in focus between the two industries. • For standards development, driving the development of business practices would be a qualitative cost-benefit analysis, with a focus on creation of standards that are less intrusive to already adopted wide-spread business practices and that recognize regional differences.

15. North American Energy Standards Board NAESB Gas-Electric Interdependency Standards & Issues February 2006 Report Prepared by the North American Energy Standards Board

16. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report Summary of Report Filed February 2006 for RM05-28-000: • 6 issues were identified in the report – three focus primarily on gas market changes, and 3 focus primarily on electric market changes • All six issues have policy implications. • All could result in standards development if so directed by either the market participants or the regulators. • The report does not ask regulators to give policy direction, but it does note that it would be very difficult to garner industry consensus without either strong direction from the market participants or strong direction from policy makers. Prepared by the North American Energy Standards Board

17. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report RM96-1-027 (RM05-28-000) NOPR: Gas Issues • Issue 1: Consider the development of standards to support Capacity Release pricing on an index for pipelines that have the FERC authority to enter into negotiated rates and discount capacity on an index basis. • The Commission clarified, releasing shippers are free to offer the same type of pricing arrangements as pipelines - gas price indices, as long as, the rate paid by the replacement shipper does not exceed the maximum rate in the pipeline’s tariff, including rate formulas that produce varying rates during the term of an agreement, as discounted rates. • RM06-21and RM07-4; Requesting comments on the capacity release program and if changes in any policies would improve the efficiency of the natural gas market. Comments due March 12, 2007. Prepared by the North American Energy Standards Board

18. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report RM96-1-027 (RM05-28-000) NOPR: Gas Issues continued • Issue 2: Review the possibility of adding an additional intraday nomination cycle with bumping rights to provide more flexibility to shippers, including power generators, with firm transportation rights such that they can nominate for natural gas supporting their market clearing times. • “… making the third intra-day nomination non-bumping creates a fair balance between firm shippers, who will have had two opportunities to reschedule their gas, and interruptible shippers and will provide some necessary stability in the nomination system, so that shippers can be confident by mid-afternoon that they will receive their scheduled flows.” Prepared by the North American Energy Standards Board

19. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report RM96-1-027 (RM05-28-000) NOPR: Gas Issues continued • Issue 3: Review the ability of pipelines to shift gas for primary firm transportation within a pipeline path without having to re-offer as secondary firm transportation service. • In most cases, it would be reasonable to permit the reassignment since the shipper already has a transportation contract with primary points through the posted constraint point and has scheduled gas through that point so that reallocating gas to a different delivery point would not pose an operational problem.The only caveat would be if Shipper 1 seeks to re-designate a secondary delivery point (outside its path) that is also being requested by Shipper 2, and the delivery point is within the path of the Shipper 2. If both secondary nominations to that point cannot be accepted, Shipper 2, with a contract path through the secondary point, would have priority.

20. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report RM05-5 (RM05-28-000) NOPR: Electric Issues • Issue 4: Review and modify the requirements for organized electric markets so that the markets clear in sufficient time to nominate within the existing gas nomination timelines. • Issue 5: Consider the development of business practices for generators that offer into the day ahead market to have the appropriate commercial arrangements to fulfill the needed obligations. Prepared by the North American Energy Standards Board

21. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report RM05-5 (RM05-28-000) NOPR: Electric Issues • The Commission concurrently opened section 206 proceedings to examine the RTO and ISO scheduling processes during emergency conditions to ensure that the RTOs and ISOs have procedures in place during emergencies to permit better synchronization of their markets with the gas market and to ensure that generators making appropriate bids into the RTO and ISO markets are able to recover their prudently incurred costs. (Docket Nos. EL07-1, EL07-2, EL07-3, EL07-4, EL07-5, EL07-6) • January 16, 2007 filing deadline has been met • The ISOs and RTOs have responded. Cal ISO has asked for an extension. Several stakeholders have filed motions to intervene. Prepared by the North American Energy Standards Board

22. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report RM05-5 (RM05-28-000) NOPR: Electric Issues • Issue 6: Develop the appropriate supporting definitions for new business practices for the Wholesale Electric Quadrant, including but not limited to definitions for: alternate fuel capability, usable alternate fuel capability, firm transportation service, firm sales service, firm supply, and “must run” generator. • The Commission responded that the report is not clear as to what affect such definitions would have on the operation of the electric grid, or what business practices would be affected, choosing not to provide guidance on whether such definitions should be developed at this time. NAESB has since re-activated the “Seams” committee which will look again at the possibility of standards for energy definitions. • Some of the definitions may be addressed as part of the OATT NOPR Reform as parts of RM05-17 and RM05-25 address definitions Prepared by the North American Energy Standards Board

24. North American Energy Standards BoardGas Electric Interdependency – February 2006 Report Next Steps • WGQ 2007 Annual Plan has an item to pursue analysis of the nominations timeline and additions to it to support electric market clearing times – controversial as it increases the value of firm transportation. • Provisional item on the WEQ 2007 Annual Plan – respond to standards development needs as an outgrowth of the WGQ effort and the reports submitted to the FERC regarding the order on inquiry. • NAESB Board of Directors receives a report on these efforts at each Board meeting, and the WEQ and WGQ Executive Committees prepare updates at each of their quarterly meetings.
