How Is PJM Different from a Local Utility? PJM does: Maintain the big picture of the transmission system regardless of ownership Have, by agreement, operational control of the transmission system Operate as profit neutral Remain totally independent of all PJM members Coordinates maintenance of generation and transmission systems 6
How Is PJM Different from a Local Utility? PJM does not: Own any transmission or generation assets Function as a publicly traded company Take ownership of the energy on the system Perform the actual maintenance on generators or transmission systems Serve, directly, any end-use (retail) customers 7

Dispatch Functions Ensure sufficient generation is available or running to satisfy the demand at any hour of the day including maintaining adequate reserves. This is called Generation Control. Monitor, operate and control the high voltage transmission system in a reliable manner. This is called Transmission Control. 11

Market Comparisons Capacity A/C needs power 3 years from now 18
Capacity vs. Energy Capacity A commitment of a resource to provide energy during PJM emergency under the capped energy price Capacity revenues paid to committed resource whether or not energy is produced by resource Daily product Energy Generation of electrical power over a period of time Energy revenues paid to resource based on participation in PJM s Day-Ahead & Real-Time Energy Markets Hourly product 19
Managing a Sea-Change 20
Gas = 75% New Generation by Fuel Type Since RPM Implementation in 2007 35,040 MW Total 21
Market Comparisons Regulation Manages when A/C cycles on and off Reserve A/C needs power when a power plant goes down 22
Market-based Ancillary Services Regulation - a service that generators offer to provide fine tuning that is necessary for effective system frequency control requirement Spinning Reserve quick response service that generators provides support when other generators trip. 23

Non-Market-based Ancillary Services Reactive Supply: Supports the net-null equation of active power withdrawal. (Tariff-based rates) Voltage Control: Supports the 60Hz frequency of the system. (Tariff-based rates) Blackstart: Supplies electricity for system restoration in the unlikely event that the entire grid would lose power. (Competitively procured) 27
