The C-train in Calgary is one of the greatest examples of electrified transport in Canada.
It is overwhelmingly popular with residents – it boasts an average weekday ridership of 325,000. It has kick started smarter, denser development around its stations. And best of all it and the City of Calgary’s operations are 100 per cent powered by renewable energy.
“It's hugely important to me. I wish I could take it every day, but it's an incredibly successful transit system,” says Calgary mayor Naheed Nenshi. “It has amongst the highest ridership of any LRT system anywhere, about 50 per cent of the people who travel downtown every day come downtown by public transit, and the majority of those use the C-Train system.”
And when you compare Calgary to the other transit systems in Canada then it starts to get really interesting. The Pembina Institute released its Fast Cities report last year and it’s compiled some fascinating data (disclosure: Green Energy Futures is presented by the Pembina Institute).
Calgary takes home the top spot when it comes to the amount of existing rapid transit lines per million residents and over the past ten years it has laid the most track out of any other city in the report. Continual investment in the system is an important factor that too many cities ignore.
A full three-car C-train carries 600 people. Not only does the C-Train take a lot of cars off the road it also helps the city grow in a smarter, denser way.
“Our next step is a big shift, and that's transit oriented development and that means making sure more people are living at the transit nodes outside of the downtown core. That's not something we've done a lot of in the past in Calgary, but it has to happen now,” says Nenshi.
And while transit oriented development is happening, it takes time. Dalhousie Station opened in 2003 and two multi-storey condo towers are going up next to it right now. Nenshi also mentioned University City, a cluster of four towers around Brentwood Station and the University of Calgary that are all sold out. Brentwood Station opened in 1990. In May Calgary City Council approved the N3 Condo project, the first parking-free condo project approved in Calgary. The project is one block from the City Hall LRT station.
“But also we need to not just think about high-rise and high-rise density around C-Trains but liveable, walkable communities around train stations that involve retail, that involve mid-rise development for residential, and they'd also have office space,” says Nenshi.
With 45 stations and nearly 60 km of laid track that makes sense. When you start talking about location efficient housing having more people live closer to an LRT station means less money spent on transportation by residents, less pollution and less congestion on the roads.
Powered by the wind
Perhaps the greatest coup of Calgary’s C-Train system is that it powered by wind energy. In 2001, Calgary city council voted to purchase 21,000 megawatt-hours of wind power a year for 10 years. That’s the amount of electricity that the LRT uses in a year.
Electrons delivered straight from wind turbines do not run the LRT. Instead it’s connected to the standard electricity grid. And while it’s still dominated by natural gas and coal Calgary’s 2001 investment meant 12 wind turbines were erected.
Then in 2012 Calgary went all-in on renewable energy, purchasing 100 per cent renewable power for all of the city’s operations. This investment meant two wind farms got built totaling 144 megawatts of installed wind capacity.
While the C-Train is still 100 per cent powered by wind the city’s other operations use a mix of renewable energies: wind, hydro, biomass and solar power. The power purchase agreement totals 450,000 megawatt hours a year or the equivalent power demand of over 65,000 Calgary homes.
It’s one of the killer apps of electrified rail transport, the ability to choose cleaner, greener options. By purchasing wind power Calgary Transit reports they are saving 56,000 tonnes of carbon dioxide emissions per year.
Cities like Calgary are playing a leadership role without breaking the bank. While the City of Calgary wouldn’t disclose the terms of their power purchase agreement with ENMAX, wind is the cheapest source of electricity in Alberta. The 2013 average pool price for wind according the Alberta Electric System Operator was 5.5 cents a kWh while coal was 7.7 cents a kilowatt-hour.
In Dec. 2014 when Quebec issued requests for proposals to build 450 MW of wind power, the average price for accepted bids was 7.6 cents/kWh, including 1.3 cents/kwH transmission costs. Solar power purchase agreements are being signed for as low as 5.84 cents a kWh in Dubai and at 8 cents/kWh in Brazil.
The bottom line is Calgary’s LRT and city operations are running on 100 per cent renewable energy, making the city a leader in Canada. Doubly cool are the phenomenal ridership numbers Calgary has achieved for it’s LRT–something that is reducing congestion, bringing down emissions and supporting the clean energy economy of the future.
