Always-on-demand from data centres strains electricity grid

Grid modernisation projects lag data centre builds

Data centres are quickly shifting from a tech story to an energy and infrastructure story—one that is fundamentally reshaping the way U.S. utilities, regulators and data centre logistics leaders plan for long-term needs. What was once a predictable growth path for the energy sector, allowing for planned, controlled grid expansion, is now being disrupted by concentrated, always-on electricity demand from digital infrastructure.

What’s happening

• U.S. data centre electricity demand is expected to nearly triple by 2030, outpacing traditional grid expansion timelines. Data centres operate 24/7, with near-zero tolerance for service outages. Some facilities equal the power demand of entire cities, creating massive, localised load spikes.
• One key timing mismatch creates critical tension for logistics teams: while data centres take one to three years to build, grid infrastructure has significantly longer lead times.
• As a result, utilities are racing to build substations, transmission lines and dedicated power corridors for data centre clusters. Roughly $2 trillion in grid modernisation investments are projected by 2030.
• This is happening against a backdrop of—and contributing to—rising overall energy costs for businesses and private users. U.S. electricity rates grew by 6.3% in 2025, significantly faster than inflation. This trend is expected to continue in 2026.

Beyond energy: Public resistance to data centres

The data centre construction boom is further complicated by several other issues that have widely generated pushback:

• Data centres are essentially buildings full of computers and other kinds of equipment that generate heat and need to be cooled. This is mostly done using water. Facilities that use evaporative water cooling compete for water resources with local businesses and communities. In some cases, data centres can use millions of gallons of water per day, equivalent to the needs of tens of thousands of homes. 
• At the same time, not all data centres have the same water needs. Facilities that use advanced closed-loop systems consume very little water. But no matter how much water is consumed, cooling data centres requires significant energy.
• Data centres can also cause noise and air pollution, especially when diesel generators are involved. According to the University of California, growing demand for AI could push the annual public health burden of the U.S. data centres’ air pollution from $6 billion in 2023 to more than $20 billion in 2028.
• All these factors will influence where and how data centres are built going forward.

Another pressure point: Geopolitics + energy flows

• Disruptions in the Strait of Hormuz do not directly affect data centres, but their impact can ripple into data centre costs by driving global oil and natural gas prices higher.
• Most importantly for electricity prices, 20% of global liquified natural gas travels through the Strait of Hormuz. Ships being unable to transport natural gas out of the Middle East has affected electricity prices in countries where power generation relies on it.
• Geopolitical turmoil combined with the data centre sector’s AI-driven need for more and more power, amplify existing energy issues even more for the sector.

The upshot: Onsite power generation

• Data centre operators are increasingly building their own power generation and storage capacity onsite. This creates an opportunity for data centres to help stabilise power grids rather than only strain them.
• Renewables make up much of this capacity, since it is often the fastest way to stand up onsite generation. Data centres are also among the largest buyers of renewable-energy power purchase agreements.

The logistics takeaway

Rising energy costs impact total landed cost

Logistics decisions for the data centre boom will be driven by the combination of the ongoing AI construction boom, power grid improvements and geopolitics-driven volatility in electricity and fuel prices.

Expect infrastructure bottlenecks and plan around them

Transmission, critical equipment and “last‑mile” power hookups now sit on longer timelines than facilities. Build schedule flexibility and dual‑sourcing into your plans to stay on track.

Onsite generation changes supply chains

Growth in behind‑the‑metre power such as renewables, batteries and gas turbines adds new inbound freight flows (fuel, components, maintenance parts) to data centre sites.

Involve logistics in the FEED stage

To accommodate all the above, early planning must account for substation equipment, transformers and long‑lead electrical components plus oversize/overweight transport, routeing and permitting—or projects risk multi‑year delays.
