Our transition to natural gas


In March, 2015 the Shepard Energy Centre became commercially operational. At 800 megawatts, it’s the largest natural gas-fuelled electricity generation facility in Alberta – producing enough electricity to meet half of Calgary’s current power needs. Shepard is approximately 30 per cent more efficient and emits approximately half the CO2 emissions than conventional coal-fired plants in Alberta. Take a tour below.


Our changing generation profile

We're working to apply new approaches to power generation that not only improve the reliability of electricity supply to our customers, but also reduce greenhouse gas (GHG) emissions and other environmental impacts.

In 2016 we eliminated coal from our generation mix, we now serve our customers across Alberta through a generation portfolio powered entirely by natural gas and wind.

Aligning with the goals of a sustainable city


In 2006, the City of Calgary (The City) laid out a vision to reduce greenhouse gas (GHG) emissions by
50 per cent below the 2005 level by 2050. ENMAX Corporation responded to The City's targets
investing in energy systems that use renewable or waste energy, such as co-generation and district energy.

While reliable electricity supports Albertans' quality of life, ENMAX also recognizes that we need to make, market and move electricity in an environmentally responsible way.

We work to encourage respect for the environment as a key value among employees, to promote environmental awareness in the community and to enhance our own corporate environmental practices. Air emissions, urban wetlands and soils management are our primary areas of environmental focus.

Our corporate responsibility objective for environment is to reduce the greenhouse gas footprint of our generation portfolio.

All customers are free to purchase natural gas services from the default supply provider or from a retailer of their choice and to purchase electricity services from the regulated rate provider or from a retailer of their choice. The delivery of natural gas and electricity to you is not affected by your choice. If you change who you purchase natural gas services or electricity services from, you will continue receiving natural gas and electricity from the distribution company in your service area. For a current list of retailers you may choose from, visit www.ucahelps.alberta.ca or call 310-4822 (toll free in Alberta).
