Bid Volume Summary

About

The Bid Volumes Summary provides a breakdown of the bid volumes (to reduce 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 “Location” and the Filter to “Wind” shows the breakdown of bid volumes at wind farms by location and that almost all the bid volumes at wind farms in the market were from Scottish wind farms in 2019.

Included Data
