Force Majeure: Emporia Compressor Station

SEV 3/5
Force Majeure Until Further Notice

TCO has declared force majeure effective January 23, 2026 due to an unexpected mechanical failure at Emporia Compressor Station Unit 3 in Greensville County, Virginia. As of this third revision (last updated March 20, 2026), TCO states there is no anticipated commercial impact under current operating conditions, but the Emporia VA-34 interconnect (E13) may be restricted if pressures or nominations fluctuate. No restoration timeline has been provided and the force majeure remains active with no confirmed curtailments.

Force majeure remains active at TCO Emporia CS with no confirmed volume curtailments and no restoration date; monitor Transco Zone 4 and Dominion South basis for any tightening if E13 interconnect restrictions are triggered.
Reroute: Moderate: Texas Eastern (TETCO, monitored) and Equitrans serve overlapping Appalachian/Mid-Atlantic markets, providing partial reroute options if commercial restrictions materialize at the Emporia E13 interconnect.
