Google’s latest clean energy move is as bold as it is ambitious. The tech giant has secured an agreement to purchase 200 megawatts of carbon-free electricity from Massachusetts-based startup Commonwealth Fusion Systems. If delivered, the electricity will come from CFS’ upcoming ARC fusion power plant in Chesterfield County, Virginia, which is expected to come online in the early 2030s.
This deal is not just another renewable energy contract. It marks one of the first commercial commitments to nuclear fusion, a technology long considered the holy grail of clean energy. Unlike wind or solar, fusion holds the promise of delivering vast amounts of energy with zero carbon emissions and without the intermittency challenges of traditional renewables. For Google, this deal aligns with its goal to run its operations entirely on carbon-free energy around the clock by 2030.
Since 2010, Google has made massive investments in clean energy, including wind, solar, geothermal and advanced nuclear. In 2024 alone, it added more than eight gigawatts of clean energy capacity to its portfolio. Its support for CFS, which it has backed since 2021, is part of a broader effort to accelerate technologies that could transform how global energy grids are powered.
Commonwealth Fusion Systems and the ARC project
Founded in 2018, Commonwealth Fusion Systems has quickly emerged as a key player among the nearly 50 privately funded companies pursuing commercial fusion. Backed by more than $2 billion in funding, CFS is taking a two-stage approach to making fusion practical. Its first milestone is SPARC, an experimental reactor under construction in Devens, Massachusetts. SPARC’s goal is to demonstrate net energy gain, meaning it produces more energy than it consumes to keep the fusion reaction going.
To achieve this, CFS is developing custom superconducting magnets capable of containing plasma heated to over 100 million degrees Celsius inside a tokamak, a doughnut-shaped fusion device that has been the basis for fusion experiments for decades. If SPARC proves successful, the next step is the ARC plant in Virginia. The planned facility will build on SPARC’s design but scale it up to deliver 400 megawatts of electricity, enough to power about 400,000 average US homes.
The broader landscape of fusion energy and tech industry involvement
Google is not alone in betting on fusion’s promise. Microsoft struck a similar deal with Helion Energy, which aims to deliver 50 megawatts of fusion power by 2028. Helion has already raised more than one billion dollars to advance its approach to commercial fusion.
These moves by big tech are more than symbolic. Data centers and the growing demands of artificial intelligence require enormous and reliable energy supplies. Fusion could offer an answer that other renewables struggle to match: a steady, high-output source of electricity with no direct emissions and minimal long-term waste.
Yet major hurdles remain. Generating net positive energy is only part of the challenge. Fusion operators must keep the reaction stable, maintain the integrity of reactor components exposed to extreme heat and neutron bombardment, and deliver power at a competitive cost. While no fusion reactor has yet crossed the line into commercial energy production, the recent influx of investment and technological breakthroughs suggests that the goal may be closer than many expected a decade ago.
Implications for the future of clean energy and data center operations
If successful, fusion energy could be transformational. A single ARC plant operating at 400 megawatts would match the output of a utility-scale natural gas plant without the associated carbon emissions. For companies like Google and Microsoft, securing a reliable fusion supply could help meet the exploding energy needs of next-generation data centers while keeping climate goals intact.
For the broader energy industry, tech companies’ willingness to lock in long-term fusion deals provides critical capital and credibility to startups racing to make fusion viable. Although many obstacles remain, Google’s commitment signals that fusion energy is shifting from the realm of scientific experiment to commercial reality, and the 2030s may bring a power source once thought impossible into everyday use.
