Linear Generators Promise 2,600-GW Fix for AI Data Center Power Crunch
1 articles · Updated · Fortune · Jun 30
Summary
A large AI data center can use as much electricity as a city of 80,000 people, and Khosla argues on-site linear generators can supply that demand without waiting for grid hookups.
More than 2,600 gigawatts of proposed projects are stuck in interconnection queues against a U.S. grid with less than half that installed capacity, while new utility connections can take seven years.
Linear generators produce electricity through a low-temperature, flameless reaction, can run on fuels from natural gas to hydrogen, scale from single-digit to hundreds of megawatts, and be deployed in months.
That setup lets data centers operate off-grid from day one and connect later, turning the grid into a complement rather than a prerequisite for new AI infrastructure.
Khosla says faster, locally deployed power could shape AI competitiveness for decades, with on-site generation already drawing investment from data center developers that cannot wait for the grid to catch up.
Is AI's private power boom a clean energy solution or a massive new bet on fossil fuels?
As data centers build their own power plants, what happens to the public electricity grid we all share?
The AI Data Center Power Crunch: Why U.S. Electricity Demand Will Triple by 2028 and How Onsite Solutions Are Reshaping the Grid
Overview
The rapid integration of AI into daily life is causing an unprecedented surge in electricity demand, with AI inference now surpassing model training as the main energy driver. This escalating demand is putting immense pressure on power grids, as US data centers already consume a significant share of electricity and are projected to use much more in the coming years. As a result, the industry is being forced to rethink power strategies, shifting towards onsite solutions and hybrid power models to ensure reliable and timely energy supply for expanding data center operations.
