2 Nine Major North American RTOs / ISOs 2

3 PJM as Part of the Eastern Interconnection Key Statistics Member companies 960+ Millions of people served 61 Peak load in megawatts 165,492 MW of generating capacity 183,604 Miles of transmission lines 62, GWh of annual energy 797,461 Generation sources 1,376 Square miles of territory 243,417 States served 27% of generation in Eastern Interconnection 28% of load in Eastern Interconnection 20% of transmission assets in Eastern Interconnection 13 + DC 3 21% of U.S. GDP produced in PJM As of 10/2015

4 Dynamic Growth 4

5 Reliability Grid Operations Supply/Demand Balance Transmission monitoring 1 PJM Focus on Just 3 Things Regional Planning 15-Year Outlook 2 Market Operation Energy Capacity Ancillary Services 3 5

6 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

7 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

11 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

15 How can we prevent problems on this system? 15

16 PJM EMS says What If? EMS Identifies a Potential Problem If this line trips 820 MW This line will overload 0 MW 16

17 Generation Re-dispatch Total supply = Demand = 820 MW MW 30 0 MW MW Bus 2 generator - Increase output Bus 1 generator - Decrease output 17

18 Market Comparisons Capacity A/C needs power 3 years from now 18

19 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

20 Managing a Sea-Change 20

21 Gas = 75% New Generation by Fuel Type Since RPM Implementation in ,040 MW Total 21

22 Market Comparisons Regulation Manages when A/C cycles on and off Reserve A/C needs power when a power plant goes down 22

23 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

24 Not All Megawatts are Created Equal Energy Storage 24 Steam Unit

25 Measuring and Paying for Performance Accuracy, 95% Precision, 74% Delay, (MW)*($/MW)*(Performance 66% Score) = Revenue Score, 25 78%

26 AES 2 MW Trailer Power: 2 MW Energy: 500 kwh 86,000 NEC Lithium Iron Phosphate batteries 24/7, unmanned and autonomous operation in PJM Regulation Market AES s Storage Applications Center, testing new technology and control strategies 26

27 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
