Expansion projects

Ridgeline Expansion Project

The Ridgeline Expansion Project includes installation of 117 miles of 30-inch pipeline and an additional 8 miles of 24-inch lateral pipeline. This expansion will provide additional transmission capacity to be able to replace coal-fired power generation at Kingston Fossil Plant with gas-fired power generation.

Construction is expected to begin in 2025.[5]

In July 2023, Enbridge applied to build the expansion.[5]
