As Bitcoin mining companies diversify into artificial intelligence and high-performance computing (HPC) data centers to shore up revenue, Nazar Khan, chief technical officer of TeraWulf — a publicly traded mining company — argues that electrical load variability is key to the long-term success of these facilities.
In an interview with Cointelegraph, Khan explained that Bitcoin miners are excellent controllable load resources because they can adjust their energy consumption every 10 minutes in response to peak demand or an oversupply of energy in the electrical grid.
However, this electrical load variability is much less pronounced with AI and HPC data centers, which require an uninterrupted stream of energy as high as 400-500 megawatts and additional energy redundancy infrastructure, such as gas generators, in case of a grid failure.

“The grid operator has a job to maintain reliability for everybody and deliver power to everybody,” the TeraWulf executive said while noting that many utility providers are incapable of meeting the massive energy demand from AI and HPC operations. Khan continued:
<blockquote>
 "Those who understand how to integrate these large loads into the right spots are going to do well. And those who just say, 'we're going to put up a lot of megawatts' aren't in tune with that. They will likely find that they won't scale and grow as much as they think or say."
</blockquote>
Khan also asserted that while he never expects these high-performance computing centers to be as nimble as Bitcoin miners in balancing the energy grid, he does expect the HPC centers to become better load-balancing resources with time.

According to the TeraWulf executive, it costs approximately $500 per kilowatt hour to build and run a Bitcoin mining facility, compared to the $5,000-$8,000 per kilowatt hour required for AI or HPC data centers.
This stark cost difference was also noted by Sabre56 CEO Phil Harvey, who argued that while diversification into the adjacent fields of high-performance computing and AI centers made sense from a business perspective, transitioning a mining facility into a data center <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/converting-mining-sites-ai-data-centers-not-seamless-sabre56-ceo" rel="null" target="null" text="null" title="null">was not a seamless process</a>.

Tech companies are increasingly turning to nuclear power to meet the massive energy demands of high-performance computing applications. Last month, Google signed a deal with nuclear engineering company Kairos to build and bring a <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/google-nuclear-power-plan-could-revolutionize-cryptocurrency-mining" rel="null" target="null" text="null" title="null">small nuclear reactor online by 2030</a>.&nbsp;&nbsp;
Microsoft also inked a deal with the Constellation Energy Corporation in September to <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/three-mile-island-nuclear-site-reopening-to-power-ai" rel="null" target="null" text="null" title="null">reopen the three-mile island nuclear site</a> to provide power for its artificial intelligence projects. As part of the deal, Constellation will provide Microsoft with a whopping 835 megawatts of power by 2028.
Earlier this year, President-elect Donald Trump said that the United States should <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/usa-can-should-put-more-energy-bitcoin-mining" rel="null" target="null" text="null" title="null">dedicate more energy</a> to mining and data center operations to stay competitive in the 21st century — signaling that his administration would focus on this issue.
