The energy giant ExxonMobil is planning a huge investment in natural gas-fired power plants that will power data centers directly, a.k.a. behind the meter, meaning they won’t have to connect to the electric grid. That will allow the fossil fuel giant to avoid making the expensive transmission upgrades that tend to slow down the buildout of new electricity generation. And it’ll add carbon capture to boot.
The company said in a corporate update that it plans to build facilities that “would use natural gas to generate a significant amount of high-reliability electricity for a data center,” then use carbon capture to “remove more than 90% of the associated CO2 emissions, then transport the captured CO2 to safe, permanent storage deep underground.” Going behind the meter means that this generation “can be installed at a pace that other alternatives, including U.S. nuclear power, cannot match,” the company said.
The move represents a first for Exxon, which is famous for its far-flung operations to extract and process oil and natural gas but has not historically been in the business of supplying electricity to customers. The company is looking to generate 1.5 gigawatts of power, about 50% more than a large nuclear reactor, The New York Times reported.
Exxon’s announcement comes as the power industry has reached an inflection point thanks to new demand from data centers to power artificial intelligence, electrification of transportation and heating, and new manufacturing investment. The demand for new power is immense, yet the industry’s ability to provide it quickly is limited both by the intermittent nature of cheap renewable power like solar and storage — plus the transmission capacity it requires — and by the regulatory barriers and market uncertainty around building new natural gas and nuclear power. While technology companies are starting to invest in bringing more nuclear power onto the grid, those projects won’t begin to bear fruit until the 2030s at the earliest.
Exxon is also not the only energy giant looking at behind-the-meter gas.
“This county is blessed with an abundance of natural gas,” Chevron chief executive Mike Wirth said at a recent event hosted by the Atlantic Council. “I think what we’re likely to see is that gas turbine generation is going to be a big part of the solution set, and a lot of it may be what’s called behind the meter … to support data centers.”
At the same time, the so-called hyperscalers are still making massive investments in renewables. Google, the investment firm TPG, and the energy developer Intersect announced a $20 billion investment “to synchronize new clean power generation with data center growth in a novel way,” Google’s President and Chief Investment Officer Ruth Porat wrote in a company blog post on Tuesday.
While Google was a pioneer in developing new renewable power to offset emissions from its operations and recently formed a partnership with Microsoft and the steel company Nucor to foster energy technology that can deliver clean power 24/7, this new project will be focused on “co-locating grid-connected carbon-free energy and data center investments into closely-linked infrastructure projects.”
These projects — the data centers and the clean power generation — would be sited close to each other, however they would not be behind the meter, a Google executive told Canary Media. Instead, Intersect will build “new clean energy assets in regions and projects of interest,” according to the blog post, with Google then acting as an offtaker for the power “as an anchor tenant in the co-located industrial park that would support data center development.” The Google data center and the Intersect-built power “would come online alongside its own clean power, bringing new generation capacity to the grid to meet our load, reduce time to operation and improve grid reliability.”
“This partnership is an evolution of the way hyperscalers and power providers have previously worked together,” Sheldon Kimber, Intersect chief executive, said in a press release. “We can and are developing innovative solutions to rapidly expand clean power capacity at scale while reducing the strain on the grid.”
