PJM s Analysis of the Clean Power Plan: Key Findings from Reference Gas Scenario
It is Feasible for PJM States to Achieve CO 2 Emissions Targets 13
Compliance Costs are 1% to 3% of recent Wholesale Market Costs to Load 14
Resource Adequacy is Maintained 15
The High Voltage Transmission System is Utilized Less Transmission Congestion in 2025 *Analysis focused on transmission limitations in 2025 at the 230 kv system and up. Limited set of 138 kv or below constraints evaluated. 16
Energy Market Prices Increase Over-Time in Response to Higher Fuel Cost, Load Growth and Emissions Market Prices 17
Capacity Market Prices Increase to Offset Resource Retirements and Load Growth 18

If Generation Takes a Short-Term View Compliance Cost Goes Up 30
Low Gas Price and Short-term View Impact on CO2 Emissions 31
Key Observations and Conclusions 1. It is feasible for the PJM states to comply with the CPP and do so with compliance costs between 1.1%-3.3% of current total wholesale costs. 2. Resource adequacy is maintained, but with a shift from coal and other fossil steam generation to new combined cycle natural gas and renewable generation. 3. Compliance with the Clean Power Plan leads to lower transmission congestion overall and shifting of congestion patterns relative to the reference case but transmission reliability studies are ongoing. 4. Mass-based, trade-ready compliance leads to the lowest compliance costs. 32
Key Observations and Conclusions 5. If natural gas prices remain low as they have been in the past several years, the PJM states would achieve or exceed the EPA mass-based emission reduction goals even in the absence of the Clean Power Plan 6. Shortening the retirement decision horizon to a 5 year window leads to nuclear retirements and an increase in compliance costs with reference case gas prices, with compliance costs remaining below 2% of current total wholesale costs for the model scenarios examined. 33
