Hybrid resources operate storage with a generation source as a single plant (e.g. solar + storage). This issue is comprised of specific recommendations from the Energy Storage Task Force (ESTF). The goal is to create rules that easily and fairly allow hybrid resources to participate in the market. This issue is comprised of the following recommendations from the ESTF.

•#5: Market participants may have more ability to judge for themselves when to charge and discharge based on their own forecast of market dynamics.
•#6: MISO does not explicitly capture the optimization of the dispatch of a single hybrid resource when the capability of that resource is in part driven by a forecasted value.
•#8: If participating as a Dispatchable Intermittent Resource (DIR), how to incorporate storage output into MISO 5-minute forecast.
•#9: Allowing option of separate or combined metering; Separate meters or single meter on storage resource and generator resource required?
•#10: Offer curve development for a hybrid is the same as for a standalone intermittent, except that a hybrid has a better performance expectation and maybe forecasting accuracy.
•#12: Clarification of how to specify bid parameters for hybrid resources: Pmax, Pmin, Ramp rate, Startup time, Max Energy Limit, Charge/discharge limits and bids based on State of Charge, Charge/discharge times, Transition time between charging/discharging
•#14: Allowing full participation of hybrid resources in ancillary service markets, including Regulating Reserve, Spinning Reserve, and Supplemental Reserves. Other Reserves may be applicable as well, Short Term Reserves and Ramp Products.

Additional issues from the ESTF are combined into IR087 - Enhanced Hybrid Resource Participation Model, which MISO views as dependent on the completion of IR086.

Updates

08/06/2021

MISO submitted Tariff revisions to define the term Hybrid Resources and establish a methodology for accrediting Hybrid Resources in the Resource Adequacy construct.

07/19/2021

MISO submitted an informational report regarding Hybrid Resources to FERC.

06/10/2021

MISO reviewed stakeholder feedback and priorities related to the Hybrid Resource Market Participation Model. MISO discussed Enhancement Suggestions in response to the March Hybrid Participation presentation given by Great Plains Institute. Stakeholders were encouraged to participate in the June 21 Hybrid Resource workshop.

03/11/2021

During the September 2020 MSC, an ad hoc stakeholder group presented a proposal for providing a near-term market pathway for hybrid resources. MISO responded in October 2020 stating that the Generation Resource, Dispatchable Intermittent Resource, and Stored Energy Resource Type II participation models should be workable for hybrid resources. The ad hoc group has since evaluated these models for viability for use by hybrid resources and worked to identify gaps and near term needs. Matt Prorok, Great Plains Institute, provided this presentation. Stakeholder requested to provide feedback on this presentation and asked MISO to provide a response at a future MSC.

02/04/2021

Market Participants requested to present at the March meeting. MISO will provide an update in Q2.

01/19/2021

The Commission issued an Order directing each Regional Transmission Organization and Independent System Operator to submit information related to hybrid resources, specifically related to (1) terminology; (2) interconnection; (3) market participation; and (4) capacity valuation.

10/08/2020

Discussed Stakeholder feedback and followed-up on questions from the September Hybrid Resources Presentation in the Market Subcommittee. The timeline was shared.

09/24/2020

MISO submitted post-technical conference comments regarding hybrid resources.

09/10/2020

Discussed Hybrid and Co-located Resources and existing modeling options in MISO. Feedback requested. Next update at October Market Subcommittee.

06/09/2020

Updated priority to Medium based on the 2020 Integrated Roadmap cycle. Added Frame and Evaluation phases to the timeline.

02/04/2020

This issue was created in December 2019 as the combination of multiple issues passed to the MSC at the conclusion of the Energy Storage Task Force. It is on the 2020 MSC management plan and a part of the 2021 Integrated Roadmap Work Plan prioritization process.
