G 200 L 200 G 200 L 200 ISO NEW ENGLAND 9 RFP Basic Concepts (Cont’d) Structured as an RFP – not an auction –Resources selected will be paid as bid –Assumes that locational ICAP is implemented to value existing resources –No additional compensation for existing generators from this process - existing generators will receive revenues from existing markets and the LICAP market Bidders can offer pricing for single or multiple year contract terms Generators must offer a capacity price and an “expected energy price” (for evaluation purposes) Demand Response Resources/Emergency Generators must offer a capacity price only

10. G 200 L 200 G 200 L 200 ISO NEW ENGLAND 10 Eligible Resources New peaking capacity Incremental peaking capacity at existing resources Demand response resources Emergency generation

11. G 200 L 200 G 200 L 200 ISO NEW ENGLAND 11 New and Incremental Peaking Capacity Not required to enroll in the ISO-NE LRP Treated as ordinary generating assets in the market Minimum size = 100 kW 10 or 30 minute response time Fully permitted resources –Must be listed as an ICAP resource –Must offer in Day Ahead and Real Time energy markets

12. G 200 L 200 G 200 L 200 ISO NEW ENGLAND 12 New and Incremental Peaking Capacity (Cont’d) Emergency-only permitted resources –Must enroll in the ISO-NE Demand Response Program – Will be given ICAP credit in accordance with the Demand Response Program
