Load variability is key to AI energy infrastructure — TeraWulf CTO

As a seasoned analyst with over two decades of experience in the energy sector, I find the trend of Bitcoin mining companies diversifying into AI and HPC data centers intriguing, yet challenging. The electrical load variability aspect is indeed crucial for long-term success, as highlighted by Nazar Khan, CTO of TeraWulf.

Bitcoin mining companies are expanding into areas like artificial intelligence and powerful computing data centers to boost their income. According to Nazar Khan, the CTO of TeraWulf (a public mining firm), managing electrical load fluctuations is crucial for the long-term prosperity of these facilities.

During a conversation with CryptoMoon, Khan pointed out that Bitcoin miners serve as flexible and manageable power sources due to their ability to quickly adapt their energy usage every 10 minutes, either scaling back during periods of high demand for electricity or reducing consumption when there’s an excess of energy supply in the power grid.

In contrast to traditional data centers, AI and HPC (High Performance Computing) facilities experience less fluctuation in electrical load due to their continuous need for a large amount (up to 400-500 megawatts) of uninterrupted power. These facilities also require extra energy backup systems like gas generators as a precaution, should the main grid fail.

According to a representative from TeraWulf, the role of the grid operator is to ensure dependability for all and supply power to everyone. However, they pointed out that numerous utility providers struggle to fulfill the vast energy requirements stemming from AI and high-performance computing (HPC) operations. Khan further explained:

“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.”

Khan further stated that although he doesn’t anticipate these advanced computing facilities to match the agility of Bitcoin miners when it comes to managing the power grid, he believes they will improve their abilities to effectively manage energy loads over time.

Massive computing power requires massive energy input

As stated by an executive at TeraWulf, the expense of constructing and maintaining a Bitcoin mining operation is around $500 per kilowatt hour. In contrast, AI or HPC data centers require anywhere from $5000 to $8000 per kilowatt hour.

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 was not a seamless process.

Due to the enormous energy requirements for advanced computing applications, technology firms are progressively leaning towards nuclear energy as a solution. For instance, in October 2024, Google entered an agreement with the nuclear engineering firm Kairos to construct and activate a compact nuclear reactor by the year 2030.

In September, Microsoft entered into an agreement with the Constellation Energy Corporation, which will enable the revival of the Three Mile Island nuclear plant to supply electricity for Microsoft’s artificial intelligence initiatives. By 2028, Constellation is set to deliver a massive amount of power – 835 megawatts – to Microsoft.

Previously this year, President-elect Donald Trump expressed a desire for increased emphasis on mining and data center activities to maintain America’s edge in the 21st century – suggesting that his government intends to prioritize this matter.
