Data Centres Strike Long-term Power Bargains

Long-term power agreements are reshaping energy markets as data centers secure clean, reliable electricity to fuel AI and cloud growth

9 Feb 2026

A quiet shift is under way in North America’s energy markets. It is not being driven by oil shocks or new laws, but by data centres. As artificial intelligence and cloud computing expand, the warehouses of servers that run them are becoming some of the grid’s most demanding customers.

A recent agreement shows how the relationship is changing. Under a 15-year deal, TotalEnergies will supply solar power for Google’s data centres in the United States. Such contracts are becoming common. Yet they point to a deeper realignment between digital firms and energy producers.

Data centres are no longer marginal users of electricity. In some regions their demand rivals that of small cities, a problem made sharper by energy-hungry AI workloads. Growth is now outpacing what many grids were built to handle. Long-term power-purchase agreements, or PPAs, offer a partial solution. They tie new generation directly to new demand.

For energy companies, these deals bring certainty. A guaranteed buyer over a decade or more makes it easier to finance large solar or wind projects. For data-centre operators, the benefits are different but just as important. They include stable prices, reliable supply and steady progress towards clean-energy pledges.

PPAs are not the only tool available. They increasingly sit alongside traditional utility contracts, on-site generation and newer technologies designed to improve reliability. Even so, long contracts have become especially attractive for renewables. By fixing demand far into the future, they reduce risk on both sides of the bargain.

Timing matters. Grid operators such as PJM, which manages power across much of the eastern United States, face rising demand and clogged interconnection queues. Data centres are adding to the strain. Deals linked to new generation can ease some pressure, but they also expose the limits of existing infrastructure. Grid upgrades and better planning remain unavoidable.

There are drawbacks. Long agreements reduce flexibility if markets shift. Renewable power still depends on a stable grid and backup supply. Yet many firms judge the trade-off acceptable. Stable demand helps unlock investment, speeds the rollout of clean energy and binds energy producers more closely to their biggest new customers.

For oil, gas and power companies, the message is clear. Digital infrastructure is no longer a distant consumer of electricity. It is becoming a central force in energy strategy. As data centres multiply, long-term power deals will play a growing role in deciding how electricity is built, financed and delivered.
