For help getting started with Short-Term Reserve, check out the Short-Term Reserve Fast Facts documents in the Documents/Whitepapers section of this page.

Short-term capacity, which can provide energy within a relatively short period of time (e.g. 30 minutes), is an important tool for maintaining reliability, providing the ability to manage capacity needs that may not be addressed by Operating Reserves and the Ramp Capability Reserve product. This project explores options, including existing and/or new pricing mechanisms, for ensuring the availability of short-term capacity in an efficient manner to address Voltage and Local Reliability (VLR), regional, and system-wide requirements. 

This issue was submitted by Potomac Economics, MISO's Independent Market Monitor (IMM) and is synonymous with State of the Market (SOM) recommendations 2016-4 and 2014-2.

Updates

11/22/2021

MISO submitted a limited waiver request of certain Tariff provisions regarding the provision by Stored Energy Resources – Type II, as well as by storage Resources that are otherwise eligible to be registered as SER–Type II but instead register as Demand Response Resource –Type II.

11/22/2021

MISO submitted Tariff revisions to reflect the fact that MISO’s systems currently do not have, and cannot feasibly acquire, the capability to clear Offers of Stored Energy Resources – Type II to provide off-line Supplemental Reserve and off-line Short-Term Reserve; and that this limitation also applies to storage Resources that are otherwise eligible to be registered as SER – Type II but instead register as Demand Response Resources – Type II.

11/04/2021

At the November 4 Market Subcommittee (MSC), MISO reported that production operation of Short-Term Reserve (STR) is on track for delivery on December 7, 2021. MISO hosted a second STR workshop to discuss submitting offers in the new MUI 2.0 system. STR tariff filings/updates are still pending at FERC. MISO discussed the limitations of Electric Storage Resources (ESR) and Stored Energy Resource (SER) Type II to provide offline STR. MISO plans to make FERC filing (Tariff changes and/or waiver) to reflect that SER-II cannot be cleared to provide offline STR and offline Supp, and issue will be addressed in connection with ESR implementation.

10/08/2021

MISO submitted Tariff revisions to ensure that the Short-Term Reserve (“STR”) product, scheduled to take effect on December 7, 2021, will not be prioritized over Regulating Reserve in MISO’s markets. MISO requests that these Tariff revisions be made effective on May 1, 2022, when the necessary software to implement the proposed Tariff revisions will be in place.

09/21/2021

MISO submitted a true-up to the Tariff revisions regarding the market procurement of Short-Term Reserve. On October 4, 2019, MISO filed proposed Tariff revisions in Docket No. ER20-42-000 to establish the STR product and on January 31, 2020, the Commission issued an order accepting the Tariff provisions on STR, effective December 7, 2021.

08/19/2021

MISO submitted Tariff revisions to clarify the ineligibility of Dispatchable Intermittent Resources (“DIRs”) and Intermittent Resources to provide online Short-Term Reserve (“STR”). MISO requests that these Tariff revisions be given the same December 7, 2021 effective date as the currently accepted Tariff provisions on STR, and that the Commission issue an order on this filing by October 19, 2021 to facilitate MISO’s preparation to implement the requested Tariff changes.

08/05/2021

MUI testing with STR enabled in CCE is planned to complete by mid-September. Production operation of the Short-Term Reserve market is on track for delivery in Q4 2021. Registration is now open for STR. Participants are encouraged to register for the August 13 workshop and participate in available training modules.

06/10/2021

MISO provided project key dates, and stakeholder engagement awareness for the Short-Term Reserve (STR) project. STR is on track for December 2021 go-live.
