Another Yukon community lines up for solar power

The community of Beaver Creek, Yukon, could potentially cut itsuse of diesel-powered generators by 60per cent, if a new solar project goes ahead.

The White River First Nation plans to build a 1.5 megawatt (MW) solar photovoltaic generation farm with 4megawatt hours (MWh) of battery energy storage forthe Beaver Creek electrical grid.

"It is very large, for sure. It's probably going to be one of the dominant features of downtown Beaver Creek for the foreseeable future," said Chris Cowx, general manager of Copper NiisuuLimited Partnership, the First Nation's development corporation.

The project proposal was filed in January with the Yukon Environmental and Socio-economic Assessment Board (YESAB).

Beaver Creek, a community of about 100 people near the Alaska border, is not connected to Yukon's main electricalgrid so it is entirely reliant on diesel power.

The First Nation says three diesel generators in the community generate around1 MW of power. The solar project would cut about 970 tons of greenhouse gas emissions, according to the First Nation.

"It's going to be located fairly near the middle of town, right where the diesel plant is located now," Cowx said, referring to the solar farm.

"And the goal is, of course, green energy. You know, that's one of the mandates that came down from my board, is green energy."

He says the new 2.4-ha (about 4.5 football fields) solar farmwon't be visible from the community.

Cowx says ATCOElectric, the community's power distributor, will buy the solar powerunder an electricity purchase agreement, and distribute it to the community.

Cowx says the land for the solar farm will be cleared this spring. But because of permafrost, the ground will need to stabilize before infrastructure canbe built. Building will happen the following summer.

"We have to order all of the equipment. And this is not stuff that [could] go down to the Source and just pick up and you know, throw in your pickup truck and drive up there," said Cowx.

"When you order these kinds of batteries and control systems and specialized solar panels and all that sort of thing you're looking at about six to nine months for delivery."

The Yukon government says the Beaver Creek solar farm, which could becompleted inthe fall of 2021, wouldbe the biggest solar array in Yukon.

Currently, the community of Old Crow is also developing a field of photovoltaic panels to offset an estimated 190,000 litres of diesel per year. ATCO will buy the solar energy, feed it into the power grid, and redistribute it to the community. It plans to produce 900 kilowatts of electricity.

Project estimated to cost$10M

The White River First Nationwill contribute some of the money for the Beaver Creekproject, but most will come from the territorialand federal governments.

It's estimated to cost about $10 million.

"The heavy lifting for this project would have to come from the government of Canada. And the government of Canada has a number of energy-related programs,"saidGeoff Woodhouse, senior policy analyst for the Yukon Development Corporation.

He says the White RiverFirst Nationsolar project is a big deal.

"Any time that we can encourage both economic and environmental sustainability in these communities, it's significant for the government," he said.

The YESABis expected to complete its review by March.
