Observation

Accepted actions and instructed energy are different views of storage duty.

A 30-day public balancing record places storage on two different measurement bases. The values belong beside one another, but they do not form a ratio.

Accepted balancing actions29.6%

Count-weighted share for the defined BM-unit group with high-confidence storage classification.

Keep the bases separate. The two values cannot be subtracted or divided into one another. They do not establish metered delivery, revenue quality, contract performance, asset health or the future duty of capacity that has not connected.
What the record can say

Frequency of accepted actions and share of instructed-trajectory energy answer different questions.

The first measure asks how often the defined storage group appears among accepted actions. The second asks how much instructed-trajectory energy appears under the role-share definition. Both describe that group inside the stated public-record window.

Evidence coordinate

A dated, frozen reading.

This observation is bound to the GB Grid observatory snapshot dated 22 September 2026. The two percentages retain their own definitions and the same 30-day aperture; neither is a metered-energy statement.
