Hydro-Québec proposes higher power tariffs for large data centres and blockchain mining
Hydro-Québec rate proposals reshape pricing for heavy electricity users
Hydro-Québec submitted a pricing plan that separates very large compute facilities from other industrial customers, creating a dedicated tariff for facilities with capacity above 5 MW. The proposal aims to align the utility's prices with comparable North American markets while limiting spillover effects on household and standard commercial bills.
Under the filing, newly connecting data hubs exceeding the threshold would face an average charge near 13¢/kWh, roughly twice the level current large-power users pay today; existing sites would be offered a five-year staged transition to that level. Parallel changes would reclassify blockchain mining activity and apply a separate, steeper band averaging about 19.5¢/kWh, with a three-year transition for incumbents.
Hydro-Québec says the restructuring is meant to ensure high-demand customers cover the costs and that Québec captures the economic value of its renewable supply. The utility also points to external trends where rapid data-centre expansion has driven material increases in system-wide customer bills in some U.S. markets.
- Current measured load: roughly 190 MW of the sector’s ~200 MW peak would fall under the new large-data-centre band.
- Forecast growth: data-centre peak demand is projected to climb to about 1,000 MW by 2035, a near sevenfold rise from today’s scale.
- Blockchain load: miners account for around 115 MW, with no anticipatory growth baked into the utility’s outlook.
All changes require sign-off from the provincial energy regulator and are targeted for implementation in the latter half of 2026 if approved. Hydro-Québec also intends to keep new project selection procedures in place for large developments so the grid is allocated where it yields the most value.

Washington moves to bind large data centers to resource and utility protections
Washington’s House passed a bill requiring large data centers (20 MW+) to disclose energy, water, refrigerant use and accept utility tariff terms to prevent cost‑shifting; the measure also phases out free carbon‑credit treatment from 2028 and tightens replacement‑hardware tax breaks, a change tied to about $63 million in new state receipts. The law arrives amid a national pushback — analysts estimate roughly $64 billion in U.S. data‑center projects have been delayed or reshaped by permitting disputes and local resistance — and will push operators and utilities to negotiate staged energization, infrastructure contributions, and other mitigation measures.
UK grid operator warns that very large data centres could raise energy bills
The chief executive of the UK’s electricity system operator warned that ultra-high-power, inflexible data‑centre campuses can increase wholesale and balancing costs unless they are sited where the system already has flexibility. He urged concentrating the very largest users — those drawing around 1 GW — near locations where renewables are often curtailed or where operators can absorb variable output, while noting developers and regulators can also blunt impacts through bespoke connection arrangements and demand‑side measures.
White House Presses Tech Firms to Absorb Data‑Center Grid Costs
The White House is pressing major cloud and AI companies for voluntary pledges to fund local grid upgrades tied to new data‑center builds to prevent utility rate increases for households. State and industry responses are fragmented — some states are moving toward binding rules and at least one hyperscaler has made a firm commitment, while regional grid proposals and operators push back — producing regulatory and investment uncertainty.
Anthropic to Underwrite Grid Upgrades for Its Data Centers to Limit Local Power‑Bill Pressure
Anthropic says it will finance utility-side upgrades and add generation capacity for its data‑center projects to avoid shifting those infrastructure costs onto local ratepayers. The company will also fund efficiency research, grid‑optimization tools and community engagement while joining a broader industry shift by hyperscalers to internalize upfront electrification costs.
HIVE Digital Technologies shifts capacity from bitcoin mining to AI data centers
HIVE will scale down ASIC bitcoin hashrate at its Boden site and repurpose power and cooling to expand AI/HPC capacity in Canada via its BUZZ arm and a Bell Canada AI Fabric partnership, targeting a near-term ramp above 4,000 GPUs and roughly $200M in contracted annualized run-rate by March 31, 2027. The move mirrors a broader industry pivot from mining to colo/HPC but carries execution risk tied to GPU supply, permitting, and interconnection timelines.
AI data centres prioritized for grid access; builders warn housing squeeze
UK proposals would let designated ‘strategic’ projects jump the national electricity-connection queue, favouring AI data centres, EV charging hubs and industrial electrification. Regulators and the system operator stress conditional terms, locational and commercial levers to internalise costs, while builders warn the shift risks prolonged delays to new homes in constrained areas.
Baker Hughes Raises Data‑Center Order Target to $3 Billion as AI Drives Power Needs
Baker Hughes has lifted its target for data-center related orders to $3 billion, citing sharply higher demand for power equipment from AI-driven compute growth. The move signals growing commercial opportunity for industrial power suppliers and raises questions about supply chain capacity and utility coordination as hyperscalers expand server farms.
AI data centers push U.S. electricity costs higher, Goldman projects
Goldman Sachs warns that rapid expansion of AI-focused data centers is a major contributor to recent and projected electricity demand growth, driving notable wholesale and retail power price increases through 2027 and easing in 2028. The pressure is uneven: concentrated buildouts have spurred local political pushback and roughly $64 billion of delayed projects, raising financing and underutilization risks that will shape who ultimately bears higher bills.
