HyFlex – Hybrids and Emerging Flexible Resources

This ESIG “HyFlex” page provides selected materials for Hybrids and Emerging Flexible Resources. Such resources are broadly characterized as resources that can start and ramp instantly without startup cost, startup time or other operational constraints. These types of resources are typically an aggregation of multiple sources of generation, storage or loads that can be controlled so as to offer both energy and other ancillary/reliability services to the grid.

The ESIG Working Groups and their Task Forces are actively working on many aspects of hybrids and flexible resources, and additional discussion and reference documents will be developed and posted when available. For information on joining and participating in ESIG Working Groups and other activities, contact info@esig.energy.

The Hybrids and Emerging Flexible Resources Task Force is working as both an online community (see https://esig.groups.io/g/HyFlexTaskForce) and as a task force of the System Operations & Market Design Working Group that meets at the Spring and Fall Technical Workshops. Participants are encouraged to join the HyFlex group for access to current discussions and drafts.

The following documents are currently available:

FERC Hybrid Resources Technical Conference (7/23/2020): Written Remarks from Mark Ahlstrom – Panel 1

Discussion Document: Hybrid Power Plants (Ahlstrom, Gelston, Plew, Kristov – Version 10/21/2019)
