Data for Landmark Study on Canada-Wide Wind Integration Now Available
October 27, 2016
CanWEA has just posted the wind data associated with our ground-breaking Canadian Wind Integration Study on our website. The initial findings of this three year study, led by GE Energy Consulting, were released back in July when the study findings were made available on our website in PDF format.
In addition to the wind data release, we have also posted national and regional Executive Summaries, a PowerPoint overview and the French version of the Report Summary.
So, what’s the significance of this study?
An impressive project team investigated a range of scenarios and sensitivities to determine how much wind can be integrated into the Canadian electricity grid, examining the barriers and solutions, as well as the costs and benefits. The findings of this major Canadian study indicate that Canada can get more than one-third of its electricity from wind energy without compromising grid reliability – and at the same time realize economic and environmental benefits.
The study evaluated 4,984 potential wind sites of which 346 were selected to perform modeling in four scenarios. The data that is now available includes the hourly modelling data, the metadata for each wind site (e.g. location details, capacity, annual energy, and capacity factor for each wind site modelled) and also what is called the 10-Minute Grid Cell Data (10-minute 2×2 grid cell meteorological and 100 meter power data). All data is only available in English.
Here are some key findings that you will see referenced on the new executive summaries:
- Canada has high-quality wind resources in all provinces, with capacity factors ranging from 34 per cent in British Columbia to 40 per cent in Nova Scotia;
- Additional wind energy displaces more expensive natural gas and coal-fired generation, even without a carbon tax, reducing greenhouse gas emissions;
- The more fossil fuels are replaced, the more operational production costs go down, through reductions in fuel consumption costs (wind has no fuel cost), emission costs, and variable operations and maintenance cost. Wind energy has an avoided-cost value in the range of Cdn$40.5-43.4 per megawatt-hour based on the various scenarios studied;
- Higher wind penetration increases export opportunities which in turn increases export revenue.
- While inter-area transmission reinforcements are required to accommodate significant increases in the levels of wind generation, operating cost savings would pay for the transmission investment relatively quickly;
- Overall, the additional regulation reserve requirements (the amount of extra back-up beyond the traditional level of back-up) across all of Canada were a small fraction of the additional wind – less than 1.7 per cent of the installed wind capacity across all study scenarios.
Here is a visual peek at what you will find in the regional summaries – in this case Alberta – that are now available on our website:
The detailed findings of the Canadian Wind Integration Study are great news for electricity system planners and policy makers at a time when each province is striving to keep electricity affordable into the future while planning to meet climate change commitments. Today, wind energy is an important source of clean, renewable energy that is cost-competitive with all other sources of new electricity generation in Canada.
The bottom lines for Canada are that 35 per cent wind penetration is achievable (we’re at five per cent of electricity demand today), system reliability issues can be addressed, new wind facilities will ensure significant electricity production cost savings while reducing emissions, and the cost of supportive inter-provincial transmission investments can be recovered quickly.
