A $500-million expansion of Wolf Midstream's natural gas liquids system is moving ahead near Edmonton, with construction already underway on key parts of the project.
The Calgary-based company announced on September 16 that it has reached a final investment decision on Phase Three of its NGL North System, an Alberta network that recovers, transports and separates natural gas liquids including ethane, propane, butane and condensate.
Some of the biggest additions will be built at Wolf's Feedstock Separation complex in Sturgeon County, northeast of Edmonton, while new processing capacity is also being added farther north near Fort McMurray and Mariana Lake.
The project is being developed with support from Wolf's shareholder, Canada Pension Plan Investment Board.
Wolf says all required permits and approvals have been secured, and construction and development on the core components are already underway.
What's being built near Edmonton
At its Sturgeon County complex, Wolf is adding a third de-ethanizer tower.
Once operating, it will help increase the site's total natural gas liquids production capacity to approximately 110,000 barrels per day, including more than 80,000 barrels per day of ethane.
The de-ethanizer expansion is expected to enter service in early 2027.
Wolf is also building a 37-megawatt natural gas-fired cogeneration facility at the same site. It will generate both heat and electricity for Wolf's operations and is expected to enter service in 2028.
A third part of the Sturgeon County expansion is expected much sooner.
Wolf is expanding its unit-train rail facility, bringing initial loading capacity to approximately 60,000 barrels per day. The terminal will handle both Wolf's products and third-party volumes, and is expected to enter service later in 2026.
The project extends far beyond Sturgeon County
Phase Three also involves substantial expansion at two natural gas liquids recovery facilities in northern Alberta.
Wolf is adding a third recovery train at Wolf Recovery Facility 2, northwest of Fort McMurray. The additional train will push processing capacity there above 1.1 billion cubic feet per day. That expansion is expected to enter service in early 2027.
Another recovery train is being added at Wolf Recovery Facility 1 near Mariana Lake, increasing its processing capacity to approximately one billion cubic feet per day. That expansion is scheduled for mid-2028.
Together, the two facilities will eventually be capable of processing more than 2.1 billion cubic feet of natural gas per day.
The recovered liquids are shipped south through Wolf's pipeline system to Sturgeon County, where they're separated into individual products.
Overall, Phase Three adds approximately 0.6 billion cubic feet per day of processing capacity to NGL North.
Danielle Smith is highlighting the investment
Alberta Premier Danielle Smith highlighted Wolf's announcement, calling the project "more good news for Alberta's energy sector."
Smith pointed to the additional processing capacity northwest of Fort McMurray and near Mariana Lake, along with the new cogeneration facility and expanded rail terminal in Sturgeon County.
She said the investment will mean more ethane, propane and butane recovered from Alberta natural gas, more feedstock available to the province's petrochemical industry, and more product moving to customers in Canada and overseas.
CPP Investments is backing Wolf Midstream
Wolf is a privately held Alberta midstream company backed by CPP Investments, the organization responsible for investing the assets of the Canada Pension Plan.
CPP Investments has been invested in Wolf for more than a decade.
In announcing Phase Three, CPP Investments managing director Bill Rogers said the organization continues to support Wolf's growth and its ability to create long-term value for the CPP Fund.
CPP Investments reported that the fund had $863.6 billion in assets as of June 30, 2026.
CPP Investments operates independently of federal and provincial governments and invests Canada Pension Plan assets on behalf of contributors and beneficiaries. This is not government spending.
This follows a $1-billion expansion announced in 2024
The latest investment isn't Wolf's first major expansion of NGL North.
In July 2024, the company announced a roughly $1-billion Phase Two expansion. That project included Wolf Recovery Facility 2 northwest of Fort McMurray, a 125-kilometre pipeline lateral, an expansion of the Sturgeon County separation facility, a new unit-train rail terminal and large-scale salt cavern storage.
Phase Two is listed by Alberta as a $1-billion project running from 2024 to 2027.
Add Phase Three and Wolf has now announced approximately $1.5 billion in NGL North investment since July 2024.
Alberta's Major Projects database lists Phase Three itself as a $500-million Sturgeon County project with a 2026-to-2028 schedule.
What NGL North actually does
NGL North is designed to recover valuable natural gas liquids before moving them to Sturgeon County for separation.
Those liquids include ethane, propane, butane and condensate.
Wolf's recovery facilities are located in northern Alberta. From there, the liquids travel roughly 450 kilometres through Wolf's transportation system to the Feedstock Separation complex in Sturgeon County.
The products can then be supplied to customers in Alberta or moved to other domestic and international markets.
More than 80,000 barrels of ethane a day
One of the biggest numbers in the expansion is the amount of ethane Wolf expects the system to be capable of producing.
Phase Three will bring total NGL production capacity at the Sturgeon County complex to approximately 110,000 barrels per day, including more than 80,000 barrels per day of ethane.
Ethane is an important feedstock for Alberta's petrochemical industry. It can be converted into ethylene, which is then used to manufacture plastics and other products.
And Wolf isn't building most of this capacity without customers lined up. The company says the vast majority of anticipated NGL production from Phase Three is already contracted under long-term, fixed-fee commercial agreements with investment-grade counterparties.
Wolf hasn't publicly identified those customers.
Even after Phase Three is complete, the system will still have room to grow. Wolf puts NGL North's ultimate design capacity at approximately three billion cubic feet of processing per day and 170,000 barrels per day of NGL production.
The company has not announced a Phase Four or provided a timeline for reaching that level.
What this means for Sturgeon County
The expansion adds another $500 million in industrial development to a part of the Edmonton region already seeing substantial investment.
The Sturgeon County site will gain the third de-ethanizer, the 37-megawatt cogeneration facility and the expanded rail-loading operation.
That rail expansion is particularly notable. Initial loading capacity will reach approximately 60,000 barrels per day, and the terminal will handle products from third parties as well as Wolf's own.
One number Wolf hasn't provided is employment. The company has not announced how many construction jobs or permanent positions Phase Three will create.
No project-specific estimate of additional municipal tax revenue for Sturgeon County was included in the announcement either.
Alberta's Industrial Heartland keeps attracting major projects
Wolf's project adds to a growing list of major industrial developments planned or underway northeast of Edmonton.
The Sturgeon County complex sits in Alberta's Industrial Heartland, Canada's largest hydrocarbon processing region.
In May, Keyera, AltaGas and CN announced plans to advance the Alberta Corridor Export Rail Terminal, another major rail project northeast of Edmonton designed to connect Alberta products with export markets.
Sturgeon County is also where Meta is developing its first Canadian data centre. Our coverage of that project and its projected impact on Alberta power bills is here.
Different industries, same county, drawing on the same grid and the same construction workforce.
Looking for work in Alberta's energy sector
Billions of dollars in energy, construction and industrial projects are moving forward across Alberta, including major developments around Edmonton and the Industrial Heartland.
Employers are hiring for work in the trades, construction, engineering, operations, maintenance and project management.
