Ksi Lisims (pronounced s’lisims) is a proposed floating liquified natural gas (LNG) export facility in northwestern BC. If a final investment decision is made in 2025, the site could be operational by 2029.

Partners

Ksi Lisims is a partnership between the Nisga’a Nation, Rockies LNG and Western LNG.

• The Nisga’a Nation owns that land on which the onshore facilities will sit.
• Rockies LNG is a partnership of eleven Canadian natural gas producers, who together are responsible for half of the gas extracted from the Western Canadian Sedimentary Basin, which includes the Montney region in northeastern BC.
• Western LNG is a Houston-based company engaged in the development of North American LNG export facilities.

Production

Ksi Lisims is expected to have the capacity to produce 12 million tonnes of LNG per year. Operations will continue for a maximum of 40 years.

The project description associated with the Environmental Assessment Certificate states that the project may have up to two floating LNG units, capable of receiving up to 2 billion cubic feet per day of natural gas, and exporting no more than 22.4 billion cubic feet per year of natural gas.

The floating LNG units are reported to be manufactured in South Korea by Samsung Heavy Industries.

The facility has storage capacity of up to 245,000 cubic metres on each floating LNG unit.

The natural gas will be provided via the Prince Rupert Gas Transmission pipeline, which will deliver gas from the Montney area in northeastern BC. The pipeline was acquired from TC Energy by a joint venture of the Nisga’a Nation and Western LNG in August 2024.

Regulatory approvals

The Ksi Lisims project received its BC Environmental Assessment Certificate in September 2025 (with conditions, Ministers’ reasons and a project description). The federal government announced its environmental approval at the same time.

The Ministers issued the Certificate despite receiving letters from several First Nations stating they did not consent to its issuance:

• Kitsumkalum First Nation;
• Lax Kw’alaams Band;
• Metlakatla First Nation;
• Haida Nation, who also did not consent to the associated vessel traffic that would transit Haida Territorial Waters.

Gitxaała Nation had not made a consent decision at the time the Certificate was issued.

Cost

Business in Vancouver reports that the cost of the facility and the associated Prince Rupert Gas Transmission pipeline is estimated at $20 billion.

In 2021, the cost of the facility alone was reported to be $10 billion, although another estimate puts the total cost at up to $26 billion.  

Sales

Ksi Lisims reports it has signed two agreements to sell its LNG. One, signed in 2025, is a 20-year agreement with an affiliate of TotalEnergies for 2 million tonnes per annum of LNG. The other agreement, with Shell, is also for 2 million tonnes per annum, and was signed in 2023.

Energy use

Ksi Lisims claims to be “net zero ready” by 2030, “using renewable hydropower from the B.C. grid.”

The facility plans to use temporary floating power barges to supply the electricity for the facility. These would be fueled by gas, but would be replaced by electricity from BC Hydro when that becomes available, a condition of the environmental assessment certificate.

A Technical Data Report, also filed on the BC Environmental Assessment Office’s web site, says the project will require 4,700 gigawatt hours of electricity per year. According to the Narwhal, Ksi Lisims has requested 600 megawatts of power from BC Hydro.

In the BC Legislature on October 30, 2025, the energy minister stated that Ksi Lisims would be the “one project, on the list of [LNG] projects” that would be using electricity from the North Coast Transmission Line for liquefaction.

Emissions

Project’s web site announcement says it is “designed to be one of the lowest-emission LNG facilities globally, powered by renewable hydroelectricity.”

A document filed with the Environmental Assessment Office states that direct GHG emissions would be about 1.9 mega tonnes of CO2 equivalent (MTCO2e) per year per year, dropping to 0.22 MTCO2e per year once BC Hydro is able to provide the electricity.
