Flexibility Markets

The scope of this Annex is all aspects of market design for power system flexibility. This includes: the whole range of market timescales, from long term investment signals to second-to-second balancing and response; the whole physical system from large centralized generation to behind the meter sources of flexibility within domestic settings and interfaces with other vectors; all sources of value that flexibility conceivably could capture, going beyond MWh to include characteristics like voltage control, repeatability, inertia, locational constraint alleviation; and aspects of the market that go beyond the trading rules such as consumer support, or how obligations (such as with respect to grid stability) are understood and checked.

The objective of the combined impact of the Annex’s activities will be:

  1. To enrich and disseminate participant’s understanding of flexibility market design
  2. To create and curate an evidence base all can draw upon to support decision making in the flexibility market space
  3. To further the debate on best practice in market design
