Data center demand doubled in the first half of 2026, and a 66-gigawatt pipeline is moving to North American regions with spare power. Electricity, not chips, is the real limit. Overlooked power producers and utilities, such as Constellation Energy, Vistra and Entergy, must supply that demand.

The 66-gigawatt pipeline can only be built near existing power that runs on demand. So building is moving away from crowded coastal grids toward the Midwest, the Southeast, and parts of Texas and the Mountain West. Before breaking ground, the cloud giants sign power purchase agreements with local utilities and independent power producers. These usually run 10-15 years at fixed or rising rates. For utilities used to slow, regulated growth, that is a big, lasting jump in revenue. Investors still value them on their regulated assets and dividend yield. A 4.78% 10-year yield weighs on utility shares. But with US crude at $91.48, higher energy prices make the contracts more valuable, since spare power can be sold at market prices. Constellation Energy (CEG), Vistra (VST) and Entergy (ETR) fit this pattern.
Investors believe data center growth mainly helps three groups. They are cloud giants such as Microsoft, Amazon and Alphabet, data center owners such as Equinix and Digital Realty, and chip suppliers such as Nvidia. They see utilities as a side beneficiary, partly reflected already in the utilities sector fund's rise over the past 6 months.
Why that may be wrong
Utility analysts value these companies on their regulated asset base and dividend yield. They do not treat 10-15 year power contracts with the cloud giants as a jump in earnings power. Tech analysts who cover the cloud giants do not model utility profits at all. The contracts fall between the two groups, so power companies tend to be valued too low. The same split left pipeline partnerships under-owned for the first 3 years of the shale boom.
This fails if data center builders switch to making their own power on site, with small modular reactors or dedicated gas plants, and skip utilities entirely. Watch for a wave of on-site reactor deals or large private power contracts that cut utilities out. Reactor developers such as NuScale or Kairos could sign large on-site power deals with the cloud giants. If that happens within 6 months, the case for grid utilities weakens a lot.
Investors treat utilities like bonds. With the 10-year yield at 4.78%, that may cap what they will pay for utility shares, whatever the earnings gains. Higher contract earnings may not make up for rates that cut the value of distant cash flows. The weakest assumption is that the cloud giants will sign contracts with grid utilities instead of building their own power on site. One deal would change the picture. If Microsoft, Amazon or Alphabet announced a large on-site nuclear or gas plant for a new campus that skips the local grid, the risk of utilities being bypassed would be real.
The closest match is the shale gas boom of 2008-2014. Pipeline companies, not the drillers, kept the most lasting value, because they owned the bottleneck. Pipeline partnerships such as Enterprise Products Partners saw their valuations rise 3-5 times as volume contracts locked in long-term cash flows. Investors first saw shale as a driller story, and the pipeline gains came 12-18 months later. Data center power may follow the same path, with AI computing as the drillers and grid power as the pipelines. In the shale boom, the asset that was physically scarce and locked up by contract won. Steady, on-demand power in regions with spare capacity is that asset now.
A 66-gigawatt pipeline of data center projects shifts toward North American regions with spare power. Demand concentrates where the grid has room. Cloud giants and shared data center operators speed up their site searches there.
To lock in power before building, developers sign 10-15 year power purchase agreements with local utilities and independent power producers in the Midwest, Southeast and Mountain West. Contracted revenue jumps for utilities valued on slow, regulated growth. Their earnings outlook changes before analysts change how they value them.
Higher contracted earnings and the old dividend-based way of valuing utilities are likely to stay out of line for 12-24 months. The companies that gain are independent power producers with gas and nuclear plants in states with spare power, and regulated utilities with spare transmission lines there. As more contracts are announced and utilities raise forecasts for data center demand, investors are likely to pay more for each dollar of their earnings. That is most likely if the 10-year yield settles and stops weighing on utility shares.
