Cheap wind power is making dams more valuable as a ‘battery’

CBC News / Don Pittis / 8 February 2021

The cost of wind and solar power have fallen so much over the last decade that they are much cheaper than building new hydroelectric dams — “The cost declines have been astounding,” said Carlson — but they have the disadvantage of being intermittent.

“The sun doesn’t shine at night,” he said someone always tells him on Twitter when he mentions solar’s cost advantages, “As if I weren’t aware of that.”

The advantage of combining less-expensive intermittent power with Quebec’s existing system of hydroelectric power dams is that it allows the power utility to use up the cheap wind power as it is produced while the water behind the dams is retained, at the ready.


Ontario to buy hydroelectricity from Quebec

Globe and Mail / Adrian Morrow, Bertrand Marotte / 21 October 2016

que-hydro20nwOntario has reached a deal to buy hydroelectric power from Quebec in a bid to cut greenhouse gas emissions by replacing some of the province’s natural gas-generated electricity.

Under the seven-year agreement, Ontario will buy two terawatt hours a year – about 1.4 per cent of the province’s total demand, or enough electricity to power a city of 240,000 people, sources in both governments said.

The two provinces agreed that Ontario will also store some of its own electricity at Hydro Quebec facilities, and to extend by five years an arrangement to swap 500 megawatts of power annually.

The deal is expected to cut Ontario’s greenhouse gas emissions by one million tonnes a year, and will replace about 15 per cent of the province’s natural gas-fired power with clean hydroelectric power from Quebec, an Ontario government source said.


How to lower your electricity bills and GHG emissions

Ontario Clean Air Alliance / Angela Bischoff / 13 June 2016

pchoiceswebWhen you turn on your computer, lamp or TV do you think about the source of the electricity you are using? Its climate impact? Its cost?

Most of us don’t give a second thought to these concerns when we hit the “on” switch, but there are important decisions pending around all of these issues in Ontario.

Our new report, Power Choices: Designing an electricity system for a rapidly changing world looks at how we could redesign our electricity system to reduce costs, lower its climate impact, and create new jobs and economic opportunities.

Open letter to Premiers Couillard and Wynne

Ontario Clean Air Alliance / 09 April 2015

Please click here to send a letter to Premiers Wynne and Couillard asking them to sign a long-term electricity cooperation agreement to save both provinces $14 billion while reducing greenhouse gas emissions.

A 14 billion win-win deal: Working together to create a green electricity future in Eastern Canada

Dear Premiers Couillard and Wynne:

On November 21, 2014 in Toronto you agreed to investigate “long-term opportunities to expand electricity trade” between Quebec and Ontario.

At the April 14, 2015 Climate Summit in Quebec City we hope that you will sign a win-win, long-term electricity supply agreement that will help both Ontario and Quebec move towards a green electricity future, while providing economic benefits of $14 billion for each province over the next 20 years.

Shift to renewable energy within Canada’s reach: academics

Globe and Mail / Ivan Semeniuk, Shawn McCarthy / 18 March 2015

hydro damCanada could shift entirely to renewable sources of electricity by 2035 and eliminate 80 per cent of its greenhouse gas emissions by mid-century, says a group of Canadian academics that is aiming to spur government action on climate change.

To get there, they recommend a national carbon-pricing plan, and greater effort to move electricity produced from low-carbon sources such as hydro dams across provincial borders.

In a 56-page policy document scheduled for release on Wednesday, more than 70 scientists, engineers and economists say Canada is in a more favourable position than most countries for a switch to renewable power, including large-scale hydroelectric. The most significant barrier is not technical or economic, but a lack of political will, they said.

The Transition Framework

Transition initiatives share many of the same goals as other groups, and work collaboratively with a variety of organizations in their local areas. Transition differs in that it focuses specifically on preparing communities for the changes associated with unprecedented resource depletion and transitioning away from fossil-fuel dependency.
