Agile Energy X, a subsidiary of Tokyo Electric Power Company (TEPCO), has begun an experiment using surplus solar energy to power Bitcoin mining.

Experiment with Solar Energy

Agile Energy X, based in Tokyo, aims to use surplus solar energy to power Bitcoin mining operations. According to Agile Energy X President Kenji Tateiwa, this initiative aims to reduce energy waste while promoting the use of green energy. In an interview with Asahi Shimbun, Tateiwa explained that the project was inspired by Japan’s “output control” practices, which involve intentionally limiting renewable energy production to balance supply and demand or due to transmission constraints.

Renewable Energy Potential in Japan

Agile Energy X has already installed Bitcoin mining machines near solar farms in the Gunma and Tochigi prefectures, located outside Tokyo, to capture and utilize excess solar energy. In 2023, approximately 1,920 gigawatt-hours of power in Japan were subjected to output control, equivalent to the annual energy consumption of 450,000 households. Projections from Agile Energy X suggest that if renewable energy makes up 50% of Japan’s energy supply, as much as 240,000 gigawatt-hours could be wasted each year due to curtailment. The company estimates that using just 10% of this surplus energy for Bitcoin mining could generate around 360 billion yen (approximately $2.5 billion) annually.

International Attention and Prospects

The concept of using surplus energy for Bitcoin mining has caught international attention. Fred Thiel, CEO of Marathon Digital Holdings, praised the initiative, suggesting that U.S. energy companies should take a similar approach. He noted that Japan is conducting forward-thinking research into Bitcoin, while other regions, such as the European Union, remain more critical of the practice. Crypto mining companies in the United States, particularly in Texas, have adopted similar strategies. Texas, known for its abundance of renewable energy, is a leading state in utilizing excess energy to balance grid supply and demand, aligning with Agile Energy X’s efforts in Japan.

Agile Energy X’s initiative to use surplus solar energy for Bitcoin mining represents an innovative approach to reducing renewable energy waste and promoting green energy, attracting international attention and setting precedents for similar projects worldwide.
