Suncor Energy (U.S.A.) Inc. owns and operates the Commerce City Refinery. The refinery is comprised of three plants from two refineries, which Suncor acquired in 2003 and 2005. This is the only facility of its kind in Colorado and the largest in the Rocky Mountain Region, processing approximately 98,000 barrels per day which in turn provides fuel and petroleum products for Coloradans. For simplicity, we often refer to this facility as the refinery.

Our operations, products, workforce, and community initiatives are local. We purchase crude from the Denver-Julesburg Basin, process it in Commerce City, and sell nearly 95% of our products – including gasoline, diesel, jet fuel, and paving asphalt – within Colorado.

We are Colorado’s primary producer of paving-grade asphalt for roads and a major supplier of fuel to the state’s Western Slope via rail and truck. Our refinery is also a key supplier to the Denver International Airport, providing about a third of its jet fuel.

Refinery operations

The Commerce City Refinery operates 24 hours a day, 7 days a week, 365 days a year. Flaring, steam venting, and fire training are part of normal, day-to-day operations as well as maintenance activities.

Community investment

Our 500+ Denver-based employees are a part of the community and we’re investing in programs that have a real local impact.

Suncor invests in our local communities by addressing community issues in ways that seek solutions and benefits for all. We show up in our community through the following:

  • Charitable donations: We contribute to charitable organizations and initiatives that align with our community investment funding priorities.
  • Sponsorship: We support non-profit and charitable activities and events that align with our community investment funding priorities and business interests through sponsorships and donations (including donations to organizations that do not have charitable status, but are conducting charitable initiatives), financial assistance, in-kind contributions, product donations, and event sponsorships.

SunCares employee program

Our employees are passionate about giving back to the communities where they live and work, and through this program, we reward volunteer efforts with monetary donations to the employee’s organization of choice.

SunCares enables our Colorado employees to log their volunteer hours and in 2020, we contributed more than 4,700 hours of volunteer time and supported 130 community organizations.
