The modernized refinery will feature best available control technology, which incorporates advances in technology and efficiencies from across the refining industry.

The facility will be more energy efficient, in full compliance with federal, state and local regulations.

The refinery is expected to run in a continuous mode averaging 45,000 barrels per day (bbls/day), which includes a 5,000 bbls/day average increase in heavy oil processing to 25,000 bbls/day.

The refinery will produce a full slate of products, including asphalt, gasoline and diesel, enhancing Husky’s ability to service the U.S. Midwest market.

Once the refinery is fully ramped up, Husky’s overall downstream throughput capacity is expected to be approximately 400,000 bbls/day.

Husky (TSX:HSE) is an integrated energy company headquartered in Calgary, Alberta. It has approximately 5,200 employees and has average daily production of about 320,000 barrels of oil equivalent per day.
