Data Centre Power Needs Shift Grid Construction Strategy

As pieces of critical infrastructure, data centres are zero-downtime, always-on facilities with an insatiable appetite for energy. The construction of these facilities has traditionally been constrained by grid capacity, with development timelines stretched by the need to build new power infrastructure before projects can break ground.

However, a study published in February 2026 by Duke University in Nature Energy has found that dozens of gigawatts of new load could be brought onto the US grid if large users were amenable to even modest curtailment.

This finding could have significant implications for construction schedules and project feasibility across the data centre sector.

Over the past 18 months, Google has been making a determined case that its facilities can be exactly that kind of flexible customer. The company has now integrated a total of 1GW of demand response capacity into its long-term energy contracts with multiple utilities across the US.

The announcement, made by Michael Terrell, Google's Head of Advanced Energy, represents the most recent step in what has become a notable shift in the tech giant's position in the energy markets.

For construction firms and developers, this approach could mean faster project approvals and reduced infrastructure requirements before building can commence.

Demand response enables faster builds

So, how exactly does this power-saving process work? The mechanics are rather straightforward, resting on the principles of "demand response". In layman's terms, demand response is when a large electricity user, like a data centre, agrees to temporarily reduce or delay its power consumption when the broader grid is under strain during peak times. In practice, this helps to keep the system stable without having to build extra infrastructure.

Google has been working hard to introduce demand response capabilities to its data centres. In effect, non-urgent computing tasks – the kind that do not require an immediate result – can be deferred or redistributed to other times and locations when the grid is under less strain.

Since announcing initial agreements with Indiana Michigan Power and Tennessee Valley Authority in 2025, Google has signed contracts with Entergy Arkansas, Minnesota Power and DTE Energy that incorporate demand response as a key resource for new data centres to connect more rapidly to local grids.

In a recent blog post, Terrell wrote: "Demand response can be deployed quickly to bridge the gap between short-term load growth and the longer timelines required to build new clean generation and storage solutions."

That gap is not trivial. In the US, the demand for energy for AI and data applications is projected to grow from 3.5% of total demand today to 8.6% by 2035, according to BloombergNEF, with data centre energy demand on course to outpace that of electric vehicles.

Michigan development showcases integrated approach

On 10 March 2026, Google revealed a separate but related agreement in Michigan that illustrates how these ambitions translate into practice on construction projects.

Google announced plans to develop a new data centre in DTE Energy's service territory in Michigan, with a commitment to enable 2.7GW of new clean resources to support the local grid. The breakdown of that figure tells its own story.

The package includes 1.6GW of solar power, 400MW of four-hour energy storage, 50MW of long-duration energy storage and 300MW of what Google terms "additional clean resources", which could encompass wind, hydro, nuclear or geothermal. The remaining 350 megawatts will be covered by demand response.

This bundled approach to energy procurement could represent a new model for large-scale construction projects, where developers package power generation, storage and flexibility into a single agreement rather than waiting for grid upgrades to be completed independently.

Alongside the energy infrastructure, Google is introducing a US$10m Energy Impact Fund to scale and accelerate energy affordability initiatives designed to drive down monthly bills for communities in Michigan, including home weatherisation, efficiency technology innovations for households and energy workforce development projects.

Whether US$10m is proportionate to the scale of the infrastructure being built – or indeed the pressure that energy-hungry facilities exert on local grids – is a question the announcement does not directly address.

Construction sector implications

Google's central argument is that flexible demand benefits everyone on the grid, not just the company itself. For the construction industry, this could mean that large-scale developments with significant power requirements may no longer face the lengthy delays traditionally associated with grid connection applications.

Demand-side flexibility reduces the need for new infrastructure designed solely to meet short-term peak system use, which is a primary driver of electricity prices. Terrell says in a blog post it in terms of system-wide savings: "By allowing utilities to cover peak demand periods with existing grid resources, demand response can help optimise the build-out of new transmission and power plants."

Research cited by Google supports the broader principle – that even modest flexibility in large electrical loads can reduce costs across an entire power system. This could influence how construction projects are designed and phased, with built-in flexibility becoming a standard feature rather than an afterthought.

Still, the company is candid about limits. "There are limits to how flexible a given data centre can be," Terrell says, "and this capability will only be available at certain locations."
