During the October 4, 2021 Distributed Energy Resources Task Force (DERTF) meeting, MISO discussed Emergency Operations with Distributed Energy Resource Aggregations (DERa). Stakeholder feedback is requested on the procedures discussed.
Please provide feedback by October 18.
The OMS DER WG discussed similar issues as to outage coordination – that metering, status, and data sharing and coordination must be paramount to ensure that all affected entities are aware of DER, DERa, and grid system status.
OMS DER WG requests MISO provide more detail on its proposal on slide 102 that indicates “possible changes for DER aggregations.”
Additional coordination and discussion is required to determine required timelines, communication pathways and involved parties for DERA Emergency Operations. This may also depend on size and location of the DERA and may be defined through interconnection agreements and/or RERRA requirements.
Xcel Energy agrees with MISO that the MISO Market Capacity Emergency (SO-P-EOP-00-02) and the TOP and BA Emergency Operations Plan Submittal (SO-P-EOP-00-008) may be the only Emergency Operating Plans (EOP’s) that will require changes.
MEMORANDUM
TO: MISO DISTRIBUTED ENERGY RESOURCE TASK FORCE
FROM: THE ENTERGY OPERATING COMPANIES
SUBJECT: FERC ORDER 2222 FILING FRAMEWORK – EMERGENCY OPERATIONS
DATE: OCTOBER 18, 2021
The following feedback is offered by the Entergy Operating Companies ("EOCs")[1] in response to the request made during the October 4, 2021 Distributed Energy Resource Task Force (DERTF) meeting concerning FERC Order 2222 filing framework and the related topic of emergency operations.
The EOCs appreciate the opportunity to comment.

At the 10/4/2021 DERTF meeting, MISO indicated that there may be only two Emergency Operations Procedures that need to be revised to consider DERas (Distributed Energy Resources Aggregations): SO-P-EOP-00-02 MISO Market Capacity Emergency and SO-P-EOP-00-008 TOP and BA Emergency Operations Plan Submittal. It be simply a matter of reviewing each of these procedures and where reference is made to specific resource types (e.g., Generation Resources, Demand Response Resources – Type I or II, generation, demand response), adding DERas as appropriate. In the case of the MISO Market Capacity Emergency procedure, MISO noted that DERas will be using the same market resource type structure as Electric Storage Resources although, unlike in the case of an ESR, a DERa will not be sending MISO its State of Charge. At this point, it’s not clear to WPPI how this will affect MISO’s handling of DERas during a MISO Capacity Emergency vs. DERAs (DER Aggregators) managing the participation of their DERas in MISO’s markets, and more discussion may be needed.
