GB Grid / Support Role Ecology v0.1

Who visibly carries the balancing burden?

This page reads public BMRS accepted bid/offer volumes as a support-role ecology. It asks which public asset classes appear in different ramp, boundary, narrowing, and concentrated-balancing windows.

Observation boundary.
Public projection only. This is not asset-health inference, dispatch causality, market advice, grid-stability assessment, or a control signal.

Period × Asset-Class Accepted Volume

All aligned settlement periods.

Layer Divergence

NESO support-field narrowing and BMRS accepted-volume concentration are tested as different layers.

Narrowing rows

Concentrated rows

Overlap rows

Visible classes

High-Cadence Support Role

Units that appear across many settlement periods.

High-Volume Support Role

Units with large 30-day accepted-volume contribution.
