Will rising demand from data centers cause electricity shortages for homes and businesses by 2028?
U.S. data centers face a projected 32-gigawatt electricity shortfall from 2026 through 2028. This supply gap represents 34 percent of the total power requirements needed to support emerging computing infrastructure.
Why it matters
Rapid expansion of data-center infrastructure is currently outpacing available regional electrical grid capacity across the country. This energy scarcity prevents installed artificial-intelligence servers from generating necessary computing capacity and revenue.
The U.S. is forecast to add 19 gigawatts of gas-turbine capacity alongside 6 gigawatts provided by Bloom Energy fuel cells by 2028. Oracle's Wisconsin-based Project Lighthouse alone requires 1.3 gigawatts to reach full operational capacity.
The players
Oracle
This American multinational computer technology corporation is currently developing a 1.3-gigawatt facility known as Project Lighthouse.
Bloom Energy
This company manufactures solid oxide fuel cells that are expected to contribute 6 gigawatts of capacity to the grid by 2028.
Nvidia
This technology company is a major producer of artificial intelligence hardware that relies on the expanding data-center infrastructure.
Broadcom
This designer and developer of semiconductor and infrastructure software products provides essential components for data-center hardware.
The details
Insufficient power threatens to delay the deployment of essential memory, optical, and power-management hardware. While Oracle's Project Lighthouse project in Wisconsin faces potential operational delays until at least October 2028, experts do not expect Nvidia and Broadcom 2027 earnings to be materially affected.
Timeline
The power shortfall is projected to persist from 2026 through 2028.
Forecast earnings for Nvidia and Broadcom are centered on 2027.
Project Lighthouse could reach full-power operation by October 2028.
Pessimistic estimates suggest Project Lighthouse delays could last until spring 2029.
The Tech Race
This power crisis marks a shift from focusing purely on software innovation to confronting the physical limitations of electrical grid capacity. The industry must now balance the rapid deployment of artificial intelligence hardware against the realities of regional energy supply.
The potential delay of data-center projects may slow the rollout of next-generation artificial intelligence services that consumers interact with daily. While personal costs are not immediately tied to this grid gap, it could create bottlenecks for future tech product launches and service updates.
The takeaway
The bottleneck in the data-center industry underscores that physical energy production is now the primary constraint on high-speed digital expansion. Stakeholders should monitor energy policy developments as they will dictate the speed at which new computing technologies reach the market.
What happens next
Project Lighthouse faces a milestone for potential full-power operation by October 2028, with a fallback date of spring 2029.
