PJM’s Operational Markets • Day-Ahead Energy Market • Real-Time Energy Market • Capacity • Financial Transmission Rights • Ancillary Services Markets • Regulation • Spinning Reserve Market • Black Start Services • Reactive Services
Market Incentives • PJM market supports reliability because generation isincented to follow real-time dispatch instructions: • If generation is following real-time dispatch instructions then it is eligible to set LMP, otherwise it become a price taker. • If generation is scheduled by PJM and is following real-time dispatch instructions then it receives a revenue guarantee of at least its specified offer data, otherwise there is not a revenue guarantee. • As a result of the incentives, no penalties need to be imposed for over or under generation
Operational Efficiency of Larger Market Pre-Integration Price Pattern Post-integration Energy Price Pattern • Lower Energy Prices across the Expanded PJM Region • ESAI’s technical study: region-wide energy price without integration would be $0.78/MWh higher in 2005 than with integration. • Spreading these savings over the total PJM RTO’s energy demand of 700 terawatt-hours (TWh) per year yields aggregate savings of over $500 million per year.
Efficiency Indicators • Market heat rate • Provides fuel adjusted measure of efficiency • Equivalent heat rate at Western Hub reduced from 11 MMBTU/ MWh in 1999 to 7.3 MMBTU/MWh in 2004

Efficiency Indicators • Regional security constrained economic dispatch impacts • Higher level of regional reliability • More efficient transmission utilization • Power Transfers • Allegheny Power Integration in 2002 - Average on-peak transfers increased by 500 MW • AEP Integration in 2004 - Average on-peak transfers increased by 750 MW
