The CER said electricity becomes increasingly central as homes, industries and technologies such as AI rely more on the grid.
Generation rises between 30 percent and more than double today’s levels by 2050, with more than 96 percent coming from non‑ or low‑emitting sources, and interprovincial electricity flows more than double in all scenarios, the regulator said.
CBC News reported that the same modelling shows electricity consumption growing 44 percent from 2023 to 2050, with system capacity climbing from 160 gigawatts to 310 gigawatts.
The CER expects wind to drive much of that growth, with output rising from 40 terawatt‑hours in 2023 to 277 terawatt‑hours by 2050, while solar also expands.
These variable sources are backed by higher generation from hydroelectricity, nuclear and natural gas, CER chief economist Darren Christie told CBC News.
