Natural Gas Intelligence · last updated

Natural gas infrastructure is finally coming to the aid of Mexico’s energy-starved southeast – welcome news for the region that could also have pricing implications in South Texas.

Line chart illustrating NGI's Agua Dulce forward fixed natural gas price curve from June 2025 to May 2027, showing seasonal price peaks near January 2026 and January 2027 above $4.80/MMBtu, with troughs below $3.50/MMBtu around May 2026 and April 2027.

TC Energy Corp’s Southeast Gateway project in Mexico, a 444-mile (with 416 miles offshore), 36-inch diameter pipeline, should begin flowing gas imminently. It would have the capacity to transport 1.3 Bcf/d of U.S. natural gas to Coatzacoalcos, Veracruz, and Dos Bocas, Tabasco.

The project “completed its mechanical work earlier this year, and we are now in the final regulatory processes to conclude and close out the project,” TC Energía Corp. vice president Leonardo Robles, who oversees commercial and business development, said at a recent energy conference.
