Bird Watching at Mayo B

Before any clearing could take place on the Mayo B site, it was important to have bird nesting surveys done to ensure the protection of any migratory birds in the area. In most cases Yukon Energy does project clearing in the winter when migratory bird nesting isn’t an issue. However for the Mayo B project the clearing couldn’t start until the spring, once we had all our permits.    A team of biologists surveyed about 30 hectares and identified 12 active nests. They flagged the nests with brightly-coloured tape and marked a ten metre buffer around each one.   Our contractor is not allowed to do any clearing inside the buffer until biologists have determined the nests are no longer in use (all nests are usually abandoned by the end of July and are only used one season).   The nesting survey work will continue for another few weeks until all areas are cleared.

Why Atlin Lake?

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.

‘One Fish, Two Fish’ - Part 2

If you have followed this blog for a while you will know that last summer about ninety Yukoners helped created an art piece for our Whitehorse Rapids fishladder as a way of marking the facility's 50th anniversary. The piece was entitled 'One Fish, Two Fish'. It proved to be so popular that we decided to have a second school of salmon created. With financial assistance from the Yukon River Panel we were able to distribute wooden fish to six schools around the territory. We are delighted with what the students did with the salmon! Many thanks to Donald Watt, who was the coordinator of this project, and to about 300 students at the following schools: Eliza Van Bibber School in Pelly Crossing Ghuch Tla Community School in Carcross Robert Service School in Dawson City St. Elias Community School in Haines Junction Teslin School in (of course) Teslin Ecole Emilie-Tremblay in Whitehorse The art piece has been assembled and is now available for viewing at our fishladder in the same area where Part 1 is located. If you are in Whitehorse please drop by and take a look. We'd love to hear if you have a favourite fish among them. We are rather partial to the ones that are swimming upside down and backwards! See if you can spot them in the photos below.

Field Work on the Gladstones

There’s a creek and a chain of four small lakes in the Aishihik area known as the Gladstone system. Normally this region doesn’t see many people. However over the last few weeks a group of scientists has been stationed there gathering information that will help Yukon Energy determine the viability of a potential hydro project. The idea, which Yukon Energy refers to as the Gladstone Diversion Concept, would involve putting in a control structure that would change the direction that the Gladstone Creek and Lakes flow. Instead of all the water going into the Yukon River drainage system as it does now, some of it would flow into Sekulmun and Aishihik Lakes, providing water to produce additional power at our Aishihik hydro plant. It could give Yukon Energy up to an extra 18 gigawatt hours of hydroelectricity annually, or almost five percent of Yukon Energy's current energy production per year (we produce approximately 370 gigawatt hours annually). Yukon Energy is working with the Champagne and Aishihik First Nations and the Kluane First Nation on this concept (the area is within the traditional territory of the Champagne, Aishihik and Kluane First Nations). But there is much research that needs to be done before we can determine if it’s a viable project. That’s where the scientists come in. They have been doing a number of studies looking at the health of the fish, the types of parasites found in both water systems, and the hydrology (water flows) in the area. Other work includes doing rare plant and amphibian surveys and studying the movement of large animals such as moose, caribou, sheep and bison. Below are photos of some of the summer work being done at Gladstone this year. Photo 1: Stefan Iwasawa from the Centre of Coastal Health and Photo 2: Stefan and Kathy Baynes from the Pacific Biological Station take samples to determine the health of the fish and to learn what parasites are in the water systems. The good news is that early results show the same organisms exist in both systems, so there should not be any significant health concerns with connecting the two water systems.

Into the Wind

As is the case for all Yukon Energy's equipment, repairing our wind turbines on Haeckel Hill takes special skills and knowledge. But along with the technical know-how comes the need to have steady nerves. Hanging in a metal basket 30 metres from the ground is not for the faint of heart. Bill Haydock, Justin Kolla and Les Rowland are three of Yukon Energy's employees who are trained and comfortable working from heights. They recently went up to the top of the smaller of our two wind turbines, the Bonus A/G, to make some repairs. “No, heights don’t bother me in the slightest,” Les said. “In fact there have been times when I’ve gone up the Vestas (our larger wind turbine) in winter, crawled on top of the nacelle (the area that contains the generator) and slid down to the back end to replace instruments. My wife just shakes her head!”   Of course any employee doing this work must be equipped with all the necessary safety gear, including a harness known as a fall arrest system. And Bill is quick to point out that no employees are forced to do aerial work. “We give people the choice. We would never send them up if they’re afraid of heights.”   In the case of the Bonus turbine, the job involved two separate tasks. The external ladder that leads to the generator had become damaged as a result of a guy-wire rubbing against it in the wind. Bill and Les used a crane and metal basket to remove the ladder and slowly and carefully lower it to the ground. They were then able to better assess its damage, and determine if it could be repaired or if it needed to be replaced. They decided a new ladder was necessary and one has been ordered and will be installed shortly.    While they were busy doing that, Justin was in the nacelle replacing a damaged control wire. He says teamwork made the job straightforward. “It really wasn’t bad at all with the three of us working together. Les and Bill steadied the man-basket so I could crawl in and out of the nacelle.” Justin has some off-site help too. A phone call to Maintenance Electrician Nick Balderas helped troubleshoot and find the problem.   Thankfully it was a beautiful day and wind speeds stayed low throughout the morning as the crew did their work. They were down off the mountain by lunch time. Scary work for some of us perhaps, but for these three it was just another day on the job.

Fishing for Information

Yukon Energy is currently looking into the possibility of using additional water from Mayo Lake for power production at the Mayo generating plant. Before we know if this is feasible we must study the lake’s ecosystem to better understand what the potential effects might be. To that end Yukon Energy recently finished a fish gillnetting program, aimed at providing information about the health and age class strength of the lake’s trout and whitefish. This is similar to studies done on Aishihik Lake every five to ten years. The number of fish allowed for capture was set after consulting with the First Nation of Na-Cho Nyak Dun (NND), Yukon Fisheries and the Department of Fisheries and Oceans. In total 346 lake trout and 408 lake whitefish were processed. Biologists took the otoliths (small bones located in the head that allows scientists to determine the fish’s age). Then the NND distributed most of the fish to people in the community. Once we have the final results of the study we will share the information with NND, Yukon Fisheries, Fisheries and Oceans and other interested parties.  Photo: NND summer student Charles Blysak helps with the gillnetting.

Power Outage Updates

Overnight Power Outage

People in parts of Whitehorse (Riverdale, a portion of Porter Creek, Crestview), those living along the Mayo Road, and residents of Carmacks, Ross River, Pelly and Faro lost power for a short while overnight. Most people had their power restored within a few minutes. Residents in the north part of the city had their power returned in less than half an hour. The cause of the outage was a tree that fell on our transmission line to Faro. The tree has since been removed and the hydro system is back to normal. Yukon Energy apologizes for this outage and the inconvenience it may have caused you.

The First Fish

It's always an exciting time when the first salmon of the season arrive at the Whitehorse Rapids Fishladder. The first one arrived yesterday, with a couple of more making their way up the ladder today. The best time to view the salmon is first thing in the morning (9 a.m.). If you can't get to the ladder see them, they can be viewed on our live salmon cam. Please note that the camera does take a few minutes to load so we ask for your patience.
