As we move towards renewable generation, the resources are in the locations they are in. It's no longer with fossil fuels, or that we can take coal or natural gas and transport it to generate power where we need it. Wind is only available where wind is, and the sun only shines where sun is. If we look at where the regional renewable resources are, we see that in British Columbia we have rain and mountains. In Alberta, they have great sun, and Saskatchewan has great sun. Alberta has great wind resources. We need to be able to take advantage of those, and as diversity allows us, connecting these diverse resources allows us to average out that variability. That's a big part of it. Each renewable on its own is inherently variable, and by being able to aggregate that, we come up with a much smoother signal that allows us to run our fossil fuel systems more efficiently at higher capacity and less, reducing our GHG emissions.
