Data Centers Drive Power Demand as Utilities Seek New Solutions

Rapid expansion of artificial intelligence infrastructure is increasing electricity demand across North America, prompting utilities and regulators to consider higher rates, alternative power supplies and flexible consumption agreements. On October 8 and 9, 2026, reports from Quebec and the United States highlighted the growing challenge of supplying energy to data centers without shifting excessive infrastructure costs onto other electricity customers.

Consultants commissioned by Hydro-Quebec told Quebec's energy regulator that North American data center electricity consumption could rise 133% between 2024 and 2030. The utility is seeking to increase rates for large data centers as it evaluates the financial consequences of serving energy-intensive facilities.

Hydro-Quebec's proposal would raise the average rate for affected data centers from 6.82 Canadian cents to 13 Canadian cents per kilowatt-hour. The utility says its average electricity production cost has reached approximately 12 cents per kilowatt-hour, raising concerns that existing rates could leave other customers covering the difference.

According to Hydro-Quebec, data centers subject to the proposed tariff currently reach peak demand of 190 megawatts, a figure that could increase to 1,000 megawatts by 2035. The utility is also proposing an average rate of 19.5 cents per kilowatt-hour for cryptocurrency mining and trading operations.

Energy consultants Alexis Renaud-Bezot and colleagues at Dunsky examined how North American jurisdictions are responding to data center expansion. Their analysis found that numerous jurisdictions have introduced specialized electricity tariffs to limit the effects of rising demand on residential customers.

Renaud-Bezot said electricity demand growth is substantially greater than the increases seen over the previous two decades. He also noted that artificial intelligence training facilities vary considerably in size, ranging from 20 megawatts to several thousand megawatts.

However, industry representatives have challenged comparisons between Quebec and other electricity markets, arguing that Hydro-Quebec's monopoly leaves customers without alternative suppliers. Marie-Pierre Boudreau, representing the Data Center Coalition, raised concerns about the lack of supplier choice in the province.

Meanwhile, investors and energy analysts are examining how the wider electricity boom could reshape infrastructure spending. Microsoft, Amazon, Alphabet, Meta Platforms and Oracle have expanded data center construction, with some facilities requiring hundreds of megawatts and the largest projects demanding a gigawatt or more.

According to estimates cited by Les Affaires, annual spending on data center campuses could rise from $800 billion in 2026 to $1.8 trillion in 2050. The International Energy Agency estimates that global data center electricity consumption could reach approximately 1,000 terawatt-hours by 2030, up from 485 terawatt-hours in 2025.

Electricity infrastructure is struggling to match the pace of technological development. Jean-Mikael Michaud of National Bank Financial said data centers can be built relatively quickly, while new power grids and connections typically require four to eight years.

Maxime Houde of iA Financial Group estimated that the United States could need almost 100 gigawatts of additional electricity between 2025 and 2030, largely because of data centers and artificial intelligence. The Electric Power Research Institute estimates that US data center consumption could reach between 4% and 9% of national electricity use before the end of the decade under different scenarios.

Natural gas remains an important near-term supply option. Adam Poulin of Desjardins Global Asset Management cited a planned Meta data center in Alberta that will receive power from a dedicated 1-gigawatt natural gas plant and remain connected to the provincial grid.

Capital Power has signed a long-term agreement to supply 250 megawatts of electricity for the project. Meanwhile, turbine manufacturers including GE Vernova, Siemens Energy and Caterpillar face growing demand, with reported waiting times for some equipment extending to 2031.

Some technology companies and utilities are also pursuing demand response, which allows data centers to temporarily reduce or shift electricity consumption during periods of grid stress. The approach could reduce the need for expensive generation and transmission upgrades while helping large facilities connect to the grid sooner.

According to the Electric Power Research Institute, surveyed data centers indicated that they could reduce peak power demand by 10% to 30%, depending on facility type. A study by Duke University's Nicholas Institute estimated that greater flexibility could save between $40 billion and $150 billion in capital investment over the next decade.

OpenAI recently agreed to reduce its grid electricity draw by up to 1 gigawatt during periods of grid stress at a planned 3.2-gigawatt facility in Georgia. In September 2026, Google, NVIDIA and Emerald AI also launched the AI Energy Management Alliance to accelerate the development of flexible data centers.

Lauren Shwisberg of the Rocky Mountain Institute said government agencies and electricity market operators are increasingly examining demand response as a way to manage the growing load. Federal regulators have also directed grid operators to study new rules for connecting large electricity users, including faster procedures for facilities that offer flexible consumption.

Alexander Kheder, an analyst at BMI, said demand response could substantially reduce the effects of peak electricity consumption. However, he noted that extending these agreements to hundreds of new facilities would require significant investment and coordinated regulatory frameworks.

In Quebec, public hearings on Hydro-Quebec's proposed data center tariffs were scheduled to continue through Friday, October 9, 2026. Representatives of Google and a coalition of environmental groups were expected to present their positions on the proposed increases in December.
