On Tuesday, it announced a deal to allow Natural Law Energy, which represents four First Nations in Alberta and one in Saskatchewan, to invest up to $1 billion in Keystone XL, an agreement that is similar to potential deals being negotiated with Native groups, Wirzba said.
The company has constructed about 124 miles of pipeline since the project was approved last March, including the border crossing, and has begun construction of 17 pump stations in the states it traverses and Alberta, he reported.
The company plans to ramp up construction in the first quarter of 2021 to take the construction work force from about 3,000 now to as many as 15,000 people, CEO Russ Girling said.
The Natural Law Energy investment depends on the group securing financing and is expected to close in the third quarter of 2021, TC Energy said. The agreement also allows the group to pursue interests in future projects related to the pipeline.
The five First Nations include the Nekaneet First Nation in Saskatchewan and the Ermineskin Cree Nation, Montana First Nation, Louis Bull Tribe and Saddle Lake Cree Nation in Alberta.
