Stoney CNG Bus Storage and Transit Facility

Project update - November 4, 2019

The new Stoney Transit Facility has won Silver in this year's National Awards for Innovation and Excellence in Public-Private Partnerships.
The City's environmentally cutting-edge facility, North America's largest indoor compressed natural gas bus fueling complex, will receive this prestigious honour at the 2019 Canadian Council for Public-Private Partnerships annual conference November 18 in Toronto.
"The City of Calgary is delighted to be recognized for our world-class LEED@ Gold CNG bus transit facility, said Doug Morgan, Acting General Manager of Transportation. "The design-build-finance-maintain approach and our collaboration with Plenary Infrastructure LP allowed us to deliver this project on time and within budget. Investments in transit are among the best investments any city can make to improving the environment, reducing congestion and improving mobility".
The new Stoney Transit Facility was officially opened on March 12, 2019. Watch a video of the Opening Event.
The new facility is located in the Stoney Industrial Area at 12620 - 15 Street N.E.

About the project

The new 44,300 square metre facility provides storage and maintenance space for Transit's new fleet of CNG buses as well as diesel buses that are currently stored outside the City's other bus garages. It is capable of housing a minimum of 424 buses, 36 maintenance bays, including two detail cleaning bays, on-site compressed natural gas fueling infrastructure, and associated staff facilities. It also supports diesel bus operations, recognizing the transition period needed to introduce CNG buses into Transit's fleet.

In the fall of 2016, The City signed a fixed price agreement with Plenary Infrastructure Calgary LP to design, build, finance and maintain the Stoney CNG Transit Facility for Calgary Transit. Plenary Infrastructure Calgary LP was chosen after extensive evaluations following an open, fair and competitive request-for-proposals process.

The City of Calgary celebrated a groundbreaking event in October 2016 to officially mark the beginning of construction for the Stoney CNG Bus Storage and Transit Facility. Watch a video of the event.

Plenary Infrastructure Calgary LP is a consortium of Plenary Group (Canada) Ltd. and PCL Investments Canada Inc. Other team members include PCL Construction Management Inc. and Johnson Controls Canada LP.

Facility operations for this P3 project will differ from Calgary Transit's typical process. Once the facility has been constructed and is operational, Plenary Infrastructure Calgary LP will receive a substantial completion payment, followed by a series of monthly payments from the City over a 30-year period. The monthly payments will cover janitorial services, routine facility and landscape maintenance, as well as major maintenance and rehabilitation of the facility for the duration of the 30-year contract.

City staff will continue to service and maintain the buses.

Project background

As a result of the existing shortfall of indoor bus storage capacity and projected growth in the next 30 years (from approximately 1,000 buses to over 2,000 buses), Calgary Transit determined that it would be best to expand the capacity of the existing Spring Gardens and to construct a new bus facility.

In 2011, City Council endorsed Calgary Transit's recommendation to incorporate CNG vehicles into the regular transit bus fleet on the basis of operational cost savings and environmental benefits. A critical requirement for a CNG powered fleet is the infrastructure is to store, fuel, and maintain the buses. CNG fueled buses are not compatible with existing facilities.

In March 2013, City Council approved the delivery of the Stoney CNG Bus Storage and Transit Facility by way of a public-private partnership (P3) DBFM model, depending on the provision of funding from PPP Canada.

Calgary Transit also launched a pilot project in March 2013 incorporating four CNG vehicles into the transit bus fleet. In 2015, the pilot concluded that the City would see upwards of $3 million in annual savings on the cost of fuel based on a fleet of 400 CNG buses.

In November 2016 The City of Calgary and the Federal Government, through PPP Canada, entered into a Financial Agreement that would see the Federal Government invests up to $46.9 million towards the construction of this facility.

By planning for the future, Calgary Transit would be able to meet its commitment to provide safe, reliable, easy to use and affordable mode of transportation.
