Federal regulators in Canada have approved a C$409 million ($307 million) project designed to increase natural gas deliveries to the western United States and southern Alberta by 275 MMcf/d.

The National Energy Board (NEB) approved TransCanada Corp.'s West Path Delivery Project on Thursday. The project would add to Nova Gas Transmission Ltd. (NGTL), TransCanada's supply collection and delivery network in Alberta and British Columbia.

Contracts with shippers that have fully booked the new capacity on West Path require completion in time for gas to start flowing by June 1, 2020. The project is part of a C$7 billion ($5.2 billion), multi-year NGTL growth program.

The NEB approval includes 28 safety and environmental conditions generated by 14 months of review and hearings. The NGTL additions cross suburban and native communities west of Calgary, Canada's gas industry capital.
