How this P.E.I. company aims to reduce diesel power by 50% in remote communities

A company in Georgetown, P.E.I., is building a new wind and energy storage system for remote communities, with the goal of displacing 50 per cent of the diesel fuel communities now use for power generation. 

Frontier Power Systems has been working in renewable energy for decades, including building large-scale wind farms on P.E.I., and is now embarking on a demonstration project in Ramea, a small island off Newfoundland.

"Our objective is to reduce the fuel consumption by 50 per cent in this community. And that's a level far beyond what's ever been done in Canada," says Frontier's general manager Carl Brothers.

He said the NextGen Arctic Power System takes the best technology from current wind turbines and puts it in turbines better suited for northern communities with no access to cranes.

"We're going to install our wind turbines in conjunction with our battery system and we are going to turn the diesel off for extended periods of time," Brothers explained. 

He said the plan is to turn off Ramea's diesel generators about 25 per cent of the time, and generate enough surplus wind power to provide thermal heat for community buildings. 

Brother said one of the challenges for companies like his to this point has been the high cost of energy storage, which he said has come down dramatically because technology has improved with the boom in popularity of electric vehicles. 

He said the company has also been focusing on building what he calls "medium wind technology," as compared to the massive turbines used on many large wind farms on P.E.I. 

"One hundred kilowatt turbines were really common 30 years ago, but now they're four and five megawatt turbines, but the 100 kilowatt turbines from 40 years ago or 30 years ago, the technology was much less advanced than it is now. 

"We've looked at the current state of the utility technology and embedded a lot — most of the advantages that the new technology has on the big turbines — on smaller turbines."

Another challenge in small remote communities is their limited access to the large cranes needed to install massive wind turbines, he notes. 

The Frontier turbines will have a customized system for putting up turbines without the use of a crane. 

Brothers said the goal of displacing 50 per cent of a community's diesel consumption has caught attention.

"There's a lot of skepticism — not skepticism, but wariness. Utilities are naturally very conservative. They're responsible for providing reliable electricity to these communities, and they take that mandate seriously," Brothers said.
