  1. Wholesale Power Costs - 101 ISO New England Energy Market April 7, 2011 Craig Kieny – Vermont Electric Cooperative

  2. Topics • Wholesale Power Costs Defined • Role of ISO New England (ISO-NE or ISO) • Energy Market

  3. Wholesale Power Costs - Defined • Costs incurred by Load Serving Entities for the construction, operation and delivery of generating and demand response resources required to serve system load and maintain reliability.

  5. ISO-NE Roles • Maintain regional transmission system integrity • Monitor loads • Dispatch generators and Price Response customers • Import/export with neighboring ISOs • Maintain proper reserve levels • Transmission upgrades • Load and generation forecasts • Generator interconnection studies Real-Time Long-Term

  6. ISO-NE Roles (continued) • Operate trading markets to promote wholesale competition • Capacity– Provides generators a minimum payment as incentive to build. • Energy– Provides resources payment for providing energy or reducing load. • Regulation– Provides payment to generators to respond to instantaneous changes to load. • Reserves– compensate generators for providing “stand-by” service.

  7. Cost Comparison of ISO-NE Markets

  8. Energy Market - Basics • Market through which ISO-NE compensates generators for being available. • Resources submit bids ($/MWh) for minimum amount willing to be paid to provide energy or reduce load. • ISO continuously dispatches resources to meet the load using least cost solution while maintaining reliability of the system. • ISO calculates hourly prices at over 1,000 pricing points in New England. • ISO credits each resource based on the price at the location it is providing energy. • ISO charges load based on the price at the location it is “consumed”. • ISO invoices each participant the difference between its resource credits and load charges.

  9. ISO Energy Settlement Examples

  11. Things to Remember • Energy Market costs are one of the major budget items. • The location of your load and resources impacts your net costs. • Costs are highly correlated to Natural Gas prices. • Potentially high degree of volatility. • Hedging can provide stability but not necessarily lowest cost.
