Volumes are what the pipeline posted (or derived from a posted cap); “est.” marks an estimate from a drop in posted capacity. Dates are the pipeline’s own, not forecasts. Click any line for its notices.

Capacity offline by day

Quantified Bcf/d in effect each gas day, stacked by market side. Bars left of today are reconstructed from each event's posted window; dots mark what the ledger actually recorded that morning. Bars right of today are posted schedules, not forecasts.

Where capacity is offline

One marker per event in effect or scheduled, sized by Bcf/d and colored by market side; green rings are events lifted in the last seven days. Hollow markers are unquantified or ceiling-only. Markers sit at the compressor station, plant or terminal named in the notice where we have its location (HIFLD), otherwise on the pipeline’s line; dashed lines are schematic routes. Hover a marker for a summary and click it for the notices; hover a line to see the system, click it to filter the calendar.

In-effect detail

Every event currently in effect, with the figure's basis. Ceiling-only postings show the remaining capacity, never a reduction, and are not in any total.

About this data One bar per outage event, built from posted critical notices; stated, derived and estimated figures are labeled, and only stated or derived reductions are totaled. How Capacity Offline works → Capacity Offline FAQ →
