Offer Volume Summary
About
The Offer Volumes Summary provides a breakdown of the offer volumes (to increase generation) via the Balancing Mechanism. For instance to show the breakdown by price or by fuel or by a number of other filter options.
For instance, setting the Grouping Filter to “Offer Price” and the Filter to “No Filter” shows the breakdown of how expensive offer volumes were in the market over time.
