Firm Transportation and Power Demand

WILLIAMS COMPANIES, INC. · 2026-11-02 · Importance 58 · Surprise 42

Williams’ planned expansions target growing natural gas demand in the Southeast, Northeast, Gulf Coast, Rockies, and Haynesville, as well as power generation and LNG markets. Transco’s Southeast Supply Enhancement is expected to add 1,597 Mdth/d, while Northeast Supply Enhancement is fully subscribed under customer precedent agreements for its expected 400 Mdth/d; the latter would transport gas from Pennsylvania to New York. Other planned projects include Line 200, with expected capacity of 3,100 Mdth/d to connect to Louisiana LNG, and Delta Access, designed to add 2,250 Mdth/d along the Transco corridor to serve growing power generation and LNG demand. Williams also has primarily fixed-price power purchase agreements for Apollo, Aquila, Socrates the Younger, and Neo, with expected capacities of 490 MW, 520 MW, 340 MW, and 682 MW, respectively; Wild Trail is fully subscribed by an NWP affiliate.

Key facts

• Wild Trail is expected to provide 83 Mdth/d of new firm transportation service by increasing capacity and using existing capacity.
• NWP transportation revenues increased due to rate increases and increased firm transportation revenues from new contracts.
• Transco’s transportation revenues are largely recovered through firm capacity reservation charges, so changes in natural gas prices and transportation volumes have little impact on revenues.
• NWP’s transportation revenues are largely recovered through firm capacity reservation charges, so changes in natural gas prices and transportation volumes have little impact on revenues.
