As the demand for cloud services, artificial intelligence, and massive data storage continues to rise, one thing has become crystal clear: data centers need more power. A lot more.
According to research by Rystad Energy, data centers and electric vehicles (EVs) will together use 290 terawatt-hours (TWh) more electricity by 2030.
They also said that the growing number of regular and AI-powered data centers, along with chip factories, will raise energy demand by 177 TWh between 2023 and 2030 reaching a total of 307 TWh, noted Rystad, an independent research and energy intelligence company.
That kind of growth is pushing the limits of our current power grid. Long delays in getting new transmission lines approved and built, along with strict permitting requirements, have left data center developers searching for faster, more reliable energy solutions.
So what are they doing? They are going off-grid and they are turning to natural gas.
Natural Gas Driving the Transition
Natural gas is playing a leading role in the self-generation trend for data centers, both for projects flying under the radar and new projects garnering headlines, according to Omdia.
“What we found out is that there’s a lot of self generation happening,” Galabov said. “In fact, it’s difficult to count all of it.” And the most popular is gas-fired generation, “that is becoming very, very mature.”
Omdia estimated that the global behind-the-meter power market for data centers will reach 35 GW by 2030, with natural gas representing the dominant fuel source. That’s about 10% of its forecast for 2030 global data center power capacity of 380 GW, which includes non-AI loads and cooling demand.
Natural Gas: A Fast, Reliable Energy Source
Many data centers are now choosing to build their own on-site power generation systems using natural gas. This trend is growing fast. Companies like FuelCell Energy, Diversified Energy, and TESIAC are working together to deliver natural gas directly to data campuses and use it to power clean and efficient fuel cell systems.
One reason natural gas is so attractive is because it can be deployed quickly and reliably. Unlike renewable sources like solar or wind that depend on weather conditions, natural gas provides constant, firm power. That makes it perfect for mission-critical operations like data centers, which need to stay operating 24/7.
Better Than Diesel
Until now, many data centers used diesel generators as backups. But diesel has major downsides: it’s expensive, polluting, and economically not favorable. Natural gas systems are cleaner and can cut power generation costs by as much as 38-45% compared to diesel, according to DataCenterDynamics.
Emissions are also significantly reduced, with remarkably lower levels of nitrogen oxides (NOx), sulfur oxides (SOx), and particulates. This is a powerful benefit for companies with ambitious sustainability goals and those navigating increasingly strict environmental regulations.Emissions are also significantly reduced, with remarkably lower levels of nitrogen oxides (NOx), sulfur oxides (SOₓ), and particulates. That’s especially important as more companies set sustainability goals and try to meet stricter emissions regulations.
A Big Opportunity for Investors
This shift towards off-grid, gas-powered data centers is creating new investment opportunities in energy infrastructure. Companies like Williams have already committed over $1.6 billion to natural gas-to-power projects for data centers.
Private investors, energy developers, and sustainability-focused funds can now get involved in projects that support both energy resilience and climate goals. These investments help build microgrids and fuel systems that reduce reliance on overburdened public grids while offering stable returns.
The move toward off-grid power is not just a trend. It’s a practical response to a fast-changing world where data is king, and uptime is everything. Natural gas offers a cleaner, faster, and more efficient way to power the data revolution and smart investors are already getting on board.
If you’re an energy investor or developer looking to support scalable, sustainable solutions, now is the time to explore this growing sector.
