A new national strategy will double the capacity of the country’s electricity grid by 2050, Prime Minister Mark Carney said as he announced the plan Thursday.

“The path to affordability is electrification; the path to competitiveness is electrification; the path to net zero is electrification,” Carney said in Ottawa. “Electrification underpins everything, our emissions, our environment, our economy.”

According to a government statement, the plan, which is called Powering Canada Strong, will lower the cost of electricity for seven in 10 Canadian households by expanding the role that natural gas plays in the energy mix.
