Demand Response Scheduled & Forced Curtailments

Background
• Enhancements to the DR baseline calculations became effective June 1, 2014
• Allows scheduled and forced curtailments of Real-Time Demand Response and Real-Time Emergency Generation assets– DR assets can preserve their baseline by submitting unadjusted
baseline values during intervals of a forced or scheduled curtailment
• As of July 15, ISO New England has received approximately 50 curtailment requests

Modification and Cancellation Guidelines
• Scheduled curtailments only– Forced curtailments are submitted after the fact, so
modifications/cancellations are unnecessary
• Modification: A later curtailment start date (same end date) or earlier end date (same start date)
– A change that results in a totally different date range will be treated as a cancellation and a new curtailment request
• Cancellation: Entire curtailment changed or removed
• Submitted through a service note
• Notification should be prior to start date of scheduled curtailment

Reminders – Scheduled Curtailments
• For days during the scheduled curtailment:– Do not submit Day Ahead Offers for any days during the curtailment
and remove any existing offers that may be carried forward– Adjust Resource availability
• DRMUI, Navigation > Hourly Resource Availability
• Submit Unadjusted Baseline values for all intervals during the curtailment unless there’s a dispatch pursuant to MR-1, III.13 (OP-4 or audit)– Submit actual meter data during OP-4/audit dispatch intervals

Reminders – Forced Curtailments
• For days with an anticipated forced curtailment:– Do not submit Day Ahead Offers and remove any existing offers that may
be carried forward for Operating Days with an anticipated forced curtailment
– Adjust Resource availability• DRMUI, Navigation > Hourly Resource Availability
– Submit Unadjusted Baseline values for all intervals during the curtailment unless:
• there’s a dispatch pursuant to MR-1, III.13 (OP-4 or audit), or• the asset had cleared day-ahead or become eligible in real-time
pursuant to MR-1, Appendix E1 on a day with an unanticipated forced curtailment
• Submit actual meter data during those intervals

• Curtailments are per asset, not facility
• Other assets at the facility should submit meter data during the curtailment

What about Facilities With Distributed Gen or Multiple Assets Behind the Same Retail Meter?
• Questions received regarding the impact on performance if:– A Distributed Generation asset is dispatched during a curtailment– A facility with multiple assets behind the same retail meter is dispatched
• M-MVDR and MR-1 modified to allow metering at the RDP for an asset comprised of both generation and load
– Existing assets at a facility can be aggregated into one– Metered demand at the RDP is used to compute the baseline and
determine asset performance
