TEPCO’s Agile Energy X Uses Surplus Solar Energy for Bitcoin Mining

Agile Energy X, a subsidiary of Tokyo Electric Power Co. (TEPCO), is tackling energy waste by harnessing surplus solar power for Bitcoin mining. Located in Gunma and Tochigi prefectures, the project aims to utilize the excess energy produced by solar farms, which would otherwise be curtailed due to grid limitations. In 2023, Japan saw over 1,920 gigawatt-hours of renewable energy wasted—enough to power 450,000 households.

Agile Energy X, founded in 2022, installed 1,300 Bitcoin mining machines as part of its pilot project. Simulations predict that by 2050, Japan’s renewable energy capacity will lead to 240,000 gigawatt-hours of waste annually. By using just 10% of this surplus energy, Bitcoin mining could generate $2.5 billion each year. This innovative approach not only addresses the challenge of renewable energy oversupply but also offers a new financial incentive for expanding Japan's green energy infrastructure.
