How RemitScan measures REMIT disclosure delay

What we measure

Under EU Regulation 1227/2011 (REMIT), market participants are required to publish Urgent Market Messages (UMMs) on authorised Inside Information Platforms (IIPs) whenever they experience or plan a generation outage that could affect wholesale electricity prices.

RemitScan continuously compares two streams:

1. ENTSO-E Transparency Platform — the grid operator's view of actual generation availability
2. Authorised IIPs — what market participants voluntarily disclose

The gap between these two streams is what we measure.

The detection algorithm

For every generation unit appearing in the ENTSO-E TP, we search the four IIPs we currently integrate for a matching UMM from the responsible market participant within a configurable tolerance window (default: 30 minutes).

A disclosure event is flagged when:

• An outage appears on the TP and no matching UMM can be found within the tolerance window, or
• A UMM is published but the MW quantity, timing, or unit reference does not match the TP observation.

Materiality scoring

Not every discrepancy is equally significant. We score each event on four components:

| Component | Weight | Description | |-----------|--------|-------------| | MW share of zone capacity | 35% | Outage MW / bidding zone installed capacity | | MW share of MP portfolio | 25% | Outage MW / MP total installed capacity | | Price impact | 25% | Realised day-ahead price deviation during the outage | | Duration | 15% | Hours of outage × MW (MWh total) |

Weights are configurable by operators. Every score is reproducible from inputs and time-versioned.

What we do not do

• We do not determine legal liability. "Potential disclosure delay" is an observation, not a verdict.
• We do not use ML in the scoring path. All scores are deterministic functions of structured fields.
• We do not publish per-MP disclosure performance until a market participant has activated their workspace.
