Force Majeure: Emporia Compressor Station

SEV 4/5
Force Majeure Until Further Notice

TCO has declared a Force Majeure at Emporia Compressor Station Unit 3 in Greensville County, Virginia, effective January 23, 2026, due to an unexpected mechanical failure. This is Revision 3 of the notice originally posted January 23, 2026; the force majeure remains active with no restoration timeline provided. The Emporia VA-34 interconnect (E13) is at risk of commercial restrictions if operating pressures or nomination levels fluctuate, though no firm curtailments have been confirmed as of this revision.

Active force majeure at TCO Emporia CS with no restoration timeline keeps upward pressure on Dominion South and TETCO M2 basis; the E13 interconnect remains at risk of restriction, and RCC language suggests TCO anticipates potential multi-day primary firm impact.
Reroute: Moderate: Texas Eastern (TETCO) and Equitrans serve overlapping Appalachian and Mid-Atlantic corridors and can absorb some volumes rerouted away from the Emporia interconnect. However, TCO is a very high-capacity system and a full bypass of the Emporia CS is unlikely without spare capacity on alternatives.
