Enbridge Announces Two Gas Transmission Projects as it Continues to Capitalize on Growing Natural Gas Demand

CALGARY, AB, Sept. 2, 2025 — Enbridge Inc. (TSX: ENB) (NYSE: ENB) (Enbridge or the Company) announced today that it has reached a final investment decision on two gas transmission projects. The Company signed commercial agreements for the Algonquin Reliable Affordable Resilient Enhancement project (AGT Enhancement), which is expected to increase deliveries on the Algonquin Gas Transmission pipeline to existing local distribution company (LDC) customers in the U.S. Northeast. In addition, through its Matterhorn joint venture, the Company reached a final investment decision on the Eiger Express Pipeline (Eiger), an up to 2.5 billion cubic feet per day (Bcf/d) pipeline from the Permian Basin to the Katy area to serve the growing U.S. Gulf Coast LNG market.

“We continue to deliver on the $23 billion of Gas Transmission opportunities we laid out at our Investor Day in March. Today’s project announcements highlight the benefits of Enbridge’s scale and demonstrate our ability to support growing natural gas demand in the U.S. Northeast, and LNG exports from the U.S. Gulf Coast,” said Cynthia Hansen, Executive Vice President and President, Gas Transmission. “These investments add visibility to, and extend, our growth outlook through the end of the decade.”

Once completed, AGT Enhancement will deliver approximately 75 Mmcf/d of incremental natural gas, under long-term contracts, to investment grade counterparties in the U.S. Northeast. Natural gas is a key component of the energy mix in the region. This project is designed to increase reliable supply and improve affordability by reducing winter price volatility for customers. Enbridge expects to invest US$0.3 billion in system upgrades within, or adjacent to, existing rights-of-way. Subject to the timely receipt of required government and regulatory approvals, Enbridge fully expects to complete AGT Enhancement in 2029.

Eiger is designed to transport up to 2.5 Bcf/d of natural gas through approximately 450 miles of 42-inch pipeline from the Permian Basin in West Texas to the Katy area. Upon anticipated completion of Eiger in 2028, Enbridge expects to own a meaningful equity interest in up to 10 Bcf/d of long-haul Permian Basin egress pipeline capacity that is connected to key storage facilities and LNG export hubs along the U.S. Gulf Coast. This project is complementary to the Whistler Parent JV assets and is backed by long-term contracts with predominantly investment grade counterparties.
