Why Atlin Lake?

Energy Supply

The Atlin River

We have talked often on this blog about the importance of finding new sources of clean energy to meet future demand. One idea we are exploring involves putting a submerged weir in the Atlin River. This would reduce the rate at which the water flows out of Atlin Lake in the fall, so that there is more water to use in the winter when we need it the most. Yukon electrical loads are highest during winter months when we have lower flows in the Yukon River. Without sufficient water, we must use diesel fuel to generate electricity.

By storing water for winter usage, Yukon Energy could increase the amount of hydro electricity we produce, displacing up to 4.8 million litres of diesel per year. This translates into a savings to Yukoners of $4.8 million per year in diesel costs and it would avoid the production of up to 12,000 tonnes of greenhouse gas emissions annually.

It's important to point out that this proposal would see us keeping Atlin Lake levels within the range of their natural highs. In other words, lake levels would not be raised above what they are now during the summer months.

The residents of Atlin have expressed concern about this idea. They have asked us why we are continuing to look into it, knowing they are opposed. We think it's a good question and we'd like you to know the answer.

It's Yukon Energy's job to find enough clean, affordable and reliable energy to meet the needs of Yukoners. It is our responsibility to look at all possible sources of clean energy. We are not a company that supports emitting GHG emissions into the air any more than is absolutely necessary and we believe that as northerners, the people of Atlin and the people in the Yukon have that as a common goal. The fact that Atlin now has a hydro plant in its community, allowing the residents to greatly reduce their diesel consumption, is testimony to that.

Our search for clean energy includes looking at geo-thermal, wind, waste to energy and additional hydro, as well as energy conservation. We are working on all these fronts and have identified a number of hydro projects in the Yukon which we are studying. However 40 percent of the water that runs through our Whitehorse dam comes from Atlin and we cannot ignore that fact. While Atlin Lake is in B.C., its waters serve a great many Yukoners.
 
If we are forced to burn more diesel it means going to our regulator, the Yukon Utilities Board (YUB), and asking for a rate increase, since diesel is more expensive than hydro. In considering our request the YUB will ask us if we have first exhausted all possible avenues looking for more hydro. We will need to be able to prove that we have. The only way we can know if the Atlin Storage Concept is do-able without undue damage to the environment is to carry out a series of studies. These studies cost money, but that is the price of doing business.
 
What we are asking of people in Atlin is to keep an open mind. Let us do the studies and see what they tell us. Only then will we know for sure if there’s a way of doing this project without harming the lake and the users of that lake.
 
We welcome our readers' comments and questions on this issue.

Have energy conservation avenues been considered? Good on you for a fairly non-partisan blog post by the way.

We have considered energy conservation and are in fact working on a discussion paper on this topic in cooperation with the Yukon government and Yukon Electrical Company Limited. Watch for details in the near future.
