Deep dive — chart 3

Chart 3 — dispatch-lane rate per zone, baseline vs recent

The chart with the operational + regulatory bite. Where score-distribution shifts translate into actual dispatch routing. E3 emergency-reserve rate collapsed 29% → 6%. Other zones stable. That is the exact zone-differential signature regulators look for.

Dispatch-lane rate per market zone, baseline vs recent

Dispatch-lane rate per zone — baseline (left) vs recent (right). E3 emergency-reserve-activation rate dropped sharply while other zones stayed stable.

What you are looking at

Grouped bars per market zone (E1 / E2 / E3 / E4 / E5)
Three colors per zone: Baseline Dispatch (green) / Demand-Response Ready (blue) / Emergency Reserve Activation (red)
Left cluster: baseline (first 30 days) — the "normal" routing per zone
Right cluster: recent (last 30 days) — the current routing per zone

What the chart shows

E1, E2, E4 — lane rates unchanged between baseline and recent.
E3 — emergency-reserve-activation rate collapses (29% baseline → 6% recent). Baseline-dispatch rate grows sharply. Demand-response-ready absorbs the remainder.
E5 — secondary movement pattern (distribution shape shifted heavily even though the exact lane-rate delta is smaller than E3).
The primary differential exists on E3 alone for the emergency-reserve-activation lane. Other zones are unaffected.

22 percentage-point differential in emergency-reserve routing. One market zone. Silently. Over 45+ days. This is the exact operational pattern the NERC EOP-011 emergency-operations-planning obligation and FERC Order 890 non-discriminatory transmission-service standard are calibrated to expose.

Why aggregate metrics missed it

Because E3 is one zone among five, the aggregate emergency-reserve-activation count barely moved: the E3 collapse rounded to noise across the whole balancing area. That is why the reserve-margin-compliance dashboard stayed green. Aggregate metrics are inherently blind to zone-differential patterns, and zone-differential patterns are inherently what regulator zone-differential analysis is built to surface.

The signal that fired the A/B/C determination

The sensor's zone-differential signal fired on the emergency-reserve-activation lane. E3 lane rate shifted -22.5 percentage points vs -0.4 percentage points for E1. Differential of 22.1 percentage points sharply exceeds the 12% threshold. Once this signal fires, the Snapshot lands on Category C by rule — no matter what any other metric shows.

The exhibit-quality read

This chart is what an ISO/RTO market monitor, FERC Section 206 investigator, or wholesale-market-manipulation plaintiff's expert witness asks the operator for first. It is also what the operator's regulatory counsel should have on file before any of those land — because the same chart, in the operator's hand, tells a different story:

Same chart, operator stance: "we identified this pattern through independent verification on Day X, initiated the following remediation on Day X+N, and here is the timeline of that remediation." The chart becomes evidence of good-faith investigation, not evidence of missed monitoring.
