On June 1, 2018, a new price-responsive demand (PRD) structure went into effect in ISO New England’s marketplace. It includes the following types of demand response:
- Active demand capacity resources (ADCRs) can participate in the Forward Capacity Market (FCM).
- Demand response resources (DRRs) can participate in the energy and reserve markets.
- Demand response assets (DRAs) are the physical entities delivering megawatts. They cannot directly participate in a marketplace.
Participation Requirements
The following requirements are illustrated in the diagram below.
ADCRs
- ADCRs with a capacity supply obligation (CSO) must have at least one DRR mapped.
- The CSO requires the associated DRRs to participate in the Day-Ahead and Real-Time Energy Markets up to the DRR’s availability or the CSO of the ADCR, whichever is lower.
DRRs
All DRRs mapped to an ADCR must be located in the same dispatch zone as the ADCR.
DRAs
While DRAs do not participate directly in any market, they can be mapped to DRRs that participate in the energy and reserve markets. When mapping DRAs, please note the following conditions:
- Individual DRAs greater than 5 MW cannot be aggregated and must be associated with their own DRR.
- Individual DRAs less than 5 MW can be aggregated in a DRR, and this DRR can be greater than 5 MW.
- All DRAs mapped to a DRR must be within the same dispatch zone and reserve zone.
