Medicine Hat looks to solar power

Medicine Hat Solar Thermal Project uses concentrated solar power to generate steam for city turbines, delivering 1 MW, zero-carbon electricity. Renewable energy, CSP, and decarbonization reduce natural gas reliance in Alberta.

Medicine Hat is hoping to become the first city in Canada to use solar energy help power the city.

The project would use solar power to create steam that would be fed into the existing city-owned power plant. That steam — instead of natural gas — would power the plant's turbines.

The solar-thermal energy project would provide one megawatt of electricity without emitting any carbon.

"Natural gas, as with other fossil fuels, is non-renewable so over time we're going to have to figure out a way to do things different than we do them today," said Russ Smith, the city's environment manager and the driving force behind the idea.

Smith said Medicine Hat, which recently saw the DP Energy solar park announced, is the perfect place for the project, even though it sits on huge reserves of natural gas.

"We've been aware for quite a while that the Medicine Hat area has some of the highest, if not the highest, solar radiation in Canada, which means we get the most sunlight hours of anywhere in Canada," Smith said.

"As we started to assess the potential for renewable energy in the Medicine Hat area, much like solar in Calgary has shown promise, solar kept coming to the top of the pile… as one of those resources that we need to understand a little bit better."

Guillermo Ordorica-Garcia, with the Alberta Research Council, said the benefit to the environment is sizeable, and aligns with solar heating in Canada efforts. "There are no fossil fuels being burned at any stage of the process," he said.

While this technology has been successful in California and Spain, and is emerging in projects such as Toronto's solar thermal deal across the country, Medicine Hat would be the first city in Canada to be powered by solar thermal energy.

The $9 million project has already received $3 million in funding from the city, but will go ahead only if the federal and provincial governments provide the additional $6 million needed.
