Curtail data centres first on system stress. Already law: keep it past 2035, and close the gaps below 75 MW.
Alberta already requires thisAsk it like thisThe law says data centres get cut before my house when the grid runs short. Is this project big enough to be covered, and what protects us after that rule expires in 2035?
Alberta already answered the fear that data centres take power from homes in a cold snap. If the grid has to shed load, every data centre of 75 MW or more is cut before anyone else, and bridged sites are cut earlier still, as soon as the grid operator determines supply will be inadequate. Three gaps remain: that earlier cut reaches bridged sites only; sites under 75 MW aren't covered unless the grid operator lowers the bar; and the whole regulation expires on May 31, 2035.
Who already does itAlberta, Alta Reg 117/2026: s.10 (who is cut first), s.2 (the 75 MW line, which the AESO may lower), s.12 (review by May 31, 2030; expires May 31, 2035). Already law, read in the regulation itself. 44
