Alberta’s grid sets record highs for wind and record lows for coal

The Alberta government’s plan to phase out coal and ramp up renewables is unequivocally a good thing. Costs for renewables have dropped sharply and coal just isn’t worth it when you factor in the health and carbon costs.

Around the world investments in wind and solar are outpacing investments in coal and natural gas two to one. And when you look at a couple of recent records within Alberta’s electricity system you can see where Alberta’s electricity system is headed.

  • On April 9th, 2016 at 1 am wind energy made up 22 per cent of net electricity generation. A record high.
  • On May 8th, 2016 at 8 am coal made up only 34 per cent of Alberta’s net electricity generation. A record low


Grant Arnold is the CEO of BluEarth Renewables, a Calgary based renewable energy developer.

"This is a sign of things to come and it's important to point out that isn't unique to Alberta. When you look at Texas and other places where there is a lot of wind energy they've successfully integrated them into the grid," says Arnold.

Angela Anderson is a spokesperson for the Alberta Electric System Operator. According to Anderson a lot of natural gas and wind energy has come online recently. The two biggest examples being the 300 MW Blackspring Ridge wind project in Vulcan County and the 800 MW natural gas fired Shepard Energy Centre both of which came online in the past two years.

“So we’re already seeing the trend of wind and natural gas replacing coal,” says Anderson.

And coal was on the downswing before the government’s climate leadership plan was even announced. When you look at coal’s share of electricity generation in Alberta over the past 10 years there’s been a 13.5 per cent drop. 


In 2019 another four units totaling 860 megawatts worth of coal fired generation capacity comes offline for good due to federal regulations.

The process of replacing those old coal generators with renewables and natural gas projects starts soon. Over the next dozen years Alberta is looking at roughly $10-15 billion worth of investment just in renewables as the province phases out coal.
