Keeping the grid up on Cortes Island

Trying to keep the grid up has been very challenging these past three weeks. BC Hydro crews were constantly on call throughout the region, since Christmas Eve, repairing power outages caused by falling trees and snow encrusted power lines. Sub-zero temperatures meant skyrocketing heating bills. When local resident John Sprungman recently asked why his lights were flickering, a BC Hydro repair technician informed him that Cortes Island is trying to draw more power than the infrastructure on Cortes can handle. BC set a new record for peak electricity demand between 5 and 6 PM on December 27th, 2021: 10,902 megawatts.

The silent strength of Indigenous renewable energy micro-grids

For the first time since the 1970s, silence descended on the tiny, isolated village of Old Crow in Canada’s Arctic in August. For the first time since the 1970s, silence descended on the tiny, isolated village of Old Crow in Canada’s Arctic in August.

For generations, the community of the Vuntut Gwitchin First Nation in the Yukon, about 100 kilometres east of the Alaskan border, had suffered the incessant drone of diesel-powered generators to meet its electricity needs.

But the fly-in community, 120 kilometres north of the Arctic Circle, was quiet for the first time in decades as the nation brought its solar energy micro-grid online, said Chief Dana Tizya-Tramm at an official COP26 side event Thursday.

Germany Broke The 12 Minute Per Year Barrier

On any given day, half a million North Americans go through a blackout that lasts 2 to 4 hours. The US economy loses $150 billion a year through these incidents. Meanwhile, on the other side of the Atlantic, the average Western European loses minutes, rather than hours, through annual power loses. The average German hasn’t experienced 20 minutes of per customer annual power losses for years and, in 2014,  Germany broke the 12 minute barrier.

Seeing Harmonic Problems On The Grid

Modern grid operators have a more complex task than their counterparts did a generation ago. There was very little intermittent energy twenty or thirty years ago and little need for sophisticated instrumentation. Now the infrastructure is aging and operators need to deal with intermittent energy sources like solar and wind, energy storage, plug-in electric vehicles, interconnects and increasing demand. They need better information, so they can react to changes fast. National Grid UK selected National Instrument’s CompactRIO platform to increase their capability of seeing harmonic problems on the grid by 400%.
