Canada Clean Power Growth Faces Grid Constraints, Report Says

Canada's clean power expansion is being held back by its fragmented electricity grid, according to a new report from GlobalData. The country's non-hydro renewable capacity is expected to grow from 20.6% to 31.4% of the total by 2035, but limited east-west transmission means surplus power from Quebec, Manitoba, and British Columbia cannot easily reach fossil-reliant provinces like Alberta and Saskatchewan. Electricity demand is forecast to rise 1.7% annually, driven by heat pumps, EVs, and data centers. GlobalData says the next decade needs coordinated transmission buildout, faster permitting, and long-term partnerships with Indigenous communities. Federal investment tax credits for clean electricity and interprovincial transmission are in place, but they don't solve the underlying provincial coordination problem.

Good breakdown of a real bottleneck. The 20.6% to 31.4% jump for wind and solar is useless if the grid can't move that power where it's needed. Provincial lines mostly run north-south into the US, not east-west between provinces. That's the part policymakers need to fix first.

The 2.1% CAGR in total capacity seems low, but transmission is the real constraint. If interprovincial lines take a decade to permit, the 2035 forecast for wind and solar looks optimistic. I'd want to see GlobalData's assumptions on storage and curtailment before betting on those numbers.

The investment tax credits are useful, but they don't fix the coordination problem. Ten provinces plan their own grids, and no federal authority can force interprovincial lines. That means the ITCs might just subsidize projects that end up curtailed or stuck in interconnection queues.

Exactly. Capex support is one thing, but the interconnection queue and different provincial reliability standards are a separate problem. Building the transmission line can take longer than building the generation it's meant to serve.

The 1.7% annual demand growth from EVs, heat pumps, and data centers is a big deal. If the grid can't expand, that load either gets met by gas peakers or gets curtailed. The article touches on it, but the ratepayer impact deserves more attention.
