City of Hamilton: Applying the natural gas advantage

The City of Hamilton is using natural gas to fuel growth, reduce energy-related costs and shrink their environmental footprint.

Hamilton Street Railway: Compressed Natural Gas (CNG) for transit

CNG compressor stationHamilton is Ontario’s first municipality in over a decade to recommit to CNG buses for transit. A cleaner burning, lower carbon fuel with almost zero particulate emissions, CNG is the perfect fit for communities that want to build a greener transit fleet.

Union Gas is partnering with Hamilton for the design, construction and maintenance of a new CNG compressor station, which will fuel 120 new buses over the next six years. Union Gas will own and maintain the compressor, and the city will be responsible for its daily operations.

It is estimated that Hamilton will save $41 million over 20 years. In addition, this will be the highest capacity station in the province, which positions it well for future revenue generation.

Renewable natural gas from the waste water treatment plant


The City of Hamilton has long been a leader in producing biogas from its sewage and storm water waste. Over fifty years ago, Hamilton began processing sludge from its Woodward Avenue Wastewater Treatment Plant. By 2006, it was using biogas to fuel a combined heat and power (CHP) plant. In 2011, the city was the first in Canada to upgrade the biogas into the equivalent of pure natural gas.

The biogas purification unit they utilize allows them to inject directly into the Union Gas natural gas distribution system, making Hamilton a producer of renewable natural gas (RNG) and creating revenue.

In addition, two generation facilities installed at the city’s Glanbrook Landfill collect methane gas to fuel plant electrical generation. On average, the generation units contribute $1.7 million to $2.0 million in annual revenue and dividends to the city.

CityHousing Hamilton recently received a cheque from Union Gas for over $1 million for energy efficiency projects, reducing energy costs and emissions in 11 of its high-rise multi-family buildings. The installation and commissioning of make-up air units, heat recovery ventilators, domestic heating and hot water boilers, and building controls will save City Housing Hamilton more than $2 million over the lifespan of the new equipment.

State of the art: Union Gas Hamilton District Office and Technical Training Centre

With the support of the City of Hamilton, Union Gas built the Hamilton District Office and Technical Training Centre. Located on a recovered brownfield site in Stoney Creek, the two-storey, 54,000 sq-ft facility showcases a number of energy-efficient technologies and uses 45 per cent less energy than a conventional building of comparable size. This new facility will help front-line Union Gas employees get the technical training they need, while contributing to the local economy.

“The City of Hamilton is always open to innovative solutions to reduce costs and our environmental impact. We have a long-standing, strong relationship with Union Gas, and will continue to work together on industry-leading energy solutions.”
