Designed to provide a method by which end-use customers may be compensated by PJM for reducing load during an emergency event.

Designed to provide an incentive to customers or curtailment service providers to reduce consumption when PJM LMP prices are high.

  • Obligated in Real Time if Bid clears

Real Time Market

  • CSP Notifies PJM via email one hour prior to reduction
  • Voluntary Curtailment

Dispatched by PJM in Real Time

  • CSP Submits operational info via eSuites

PJM pays Zonal LMP

  • Resource is made whole to its offer value, which includes:
    • Minimum dispatch price
    • Minimum down time
    • Shutdown costs
  • Full Emergency participants also receive capacity credit

If Zonal LMP < $75/MWh,

  • PJM pays Zonal LMP - Retail Rate (Retail Rate = Generation + Transmission)

If Zonal LMP > = $75/MWh,

  • PJM pays Zonal LMP

**Except Real Time LMP Based Customer

Scheduled MW Reduction = 5

Actual MW Reduction = 4

Real Time Hourly Zonal LMP = $40

Retail Rate (GT) = $35

Imagine If…..

Customer wants to be Dispatched by PJM

  • Shutdown Costs = $1,500
  • Minimum Down Time = 6 Hours
  • MW Reduction = 5 MW
  • Retail Rate (G&T) = $35 /MWh

Action

Customer Decides to allow PJM to Dispatch in Real Time

Customer submits operational info to PJM (Bid Price ($87) > Marginal Cost)

PJM Forecasts Real Time LMP > $87.00 Hours 12 – 18

PJM dispatches load reduction
