What problem are we trying to solve: Reliability • NEPOOL reliability standard is 1 day outage in 10 years • Translates to Loss Of Load Expectation (LOLE) = 0. 1 day/year • NEPOOL Installed Reserve is 31% of peak load in 20042005 • NEPOOL Required Reserve is 12. 4% of peak load in 2004 -2005 2

It is not a capacity issue. We have plenty of capacity. It’s an operating reserves issue! 6
Coalition Alternative Filed at FERC 03/22/2004 • Implement Locational Operating Reserve Market – Ensures that units needed for operating reserve are adequately compensated – Newly implemented region wide Forward Reserves Market cleared at $4. 495/k. W-month last January • Implement single region-wide ICAP market – – NEPOOL historically planned for reliability on a pool wide basis Integrates transmission planning and operating realities Compensates all generators for comparable services Demand curve key points set at: • 100% of Objective Capability, not 106. 7% • X-intercept at 112% of Objective Capability, not 118% • Same as NYISO 7
Coalition Alternative (continued) • Units compensated in the Locational Operating Reserve Market are units needed for: – 2 nd contingency reserve coverage – Local voltage support – Or other local operating needs • Existing units receive a transitional payment under cost-of-service type (RMR) agreements • Contract forward for new resources needed for Locational Operating Reserve Market under RFP 8
Coalition Alternative (Continued) • ISO/NEPOOL provides 3 -year notice prior to changing the price signals established in the ICAP demand curve • Participating ICAP resources provide three-year commitment to remain on the system • No delisting allowed • Liquidated damages for failure to perform • ISO approval of maintenance schedule • New generation should be fully integrated into the grid 9
ISO Vs Coalition Alternative Costs Total 5 Year Costs $M ISO No Cap $2, 865 ISO W/ Cap $1, 591 ISO Adjusted $597 Coalition Alternative $154 10
