Canaan partners with a Japanese utility for the first state-linked Bitcoin mining project using grid-stabilizing hydro-cooled rigs.
Canaan has signed a new deal to provide Bitcoin mining equipment to a major Japanese utility.
The agreement marks Japan’s first known government-linked Bitcoin mining initiative and aligns the country with others where public resources support digital asset infrastructure.
Canaan to Support Grid-Stability Project with Mining Hardware
Canaan announced that its Avalon A1566HA mining rigs will be used in a new energy project focused on grid stabilization. The company said the hydro-cooled servers would adjust hashrate and voltage in real time to balance energy loads.
Although the partner utility remains unnamed, Canaan confirmed the project would begin operations by the end of 2025. The initiative is for improving power-grid efficiency using mining infrastructure capable of adapting to shifting energy supply and demand.
CEO Nangeng Zhang stated that “utilities can leverage Bitcoin mining as a digital load balancer.” He added that the company plans to expand similar projects across multiple global regions next year.
Japan Becomes 11th Country to Engage in State-Aligned Bitcoin Mining
Matthew Sigel from VanEck confirmed that Japan has now joined a list of 11 countries where Bitcoin mining uses government-linked infrastructure. He noted that all 10 of Japan’s regional utilities are partly owned by the state.
While rumors have circulated for years that TEPCO (9501 JP) was quietly mining Bitcoin, no confirmation ever surfaced.

While Canaan did not confirm the partner’s identity, past activity by Tokyo Electric Power Company (TEPCO) connects the firm to earlier mining trials. In 2024, TEPCO’s subsidiary Agile Energy X ran small Bitcoin mining operations using surplus renewable energy.
Sigel explained that even without confirmation of TEPCO’s direct involvement, the project qualifies as a state-aligned mining effort due to public ownership. He made these remarks on X, responding to questions about the announcement.
Project Tied to Renewable Energy and Regulatory Reform
Reports from The Asahi Shimbun in 2024 showed that TEPCO’s trials aimed to use surplus solar and wind power. These experiments in Gunma and Tochigi prefectures helped prevent energy waste during low-demand periods.
The Canaan project continues this trend, using mining to support energy efficiency. The rigs can switch between overclocking and underclocking, helping manage power use more effectively.
Japan is also advancing crypto regulation, with proposals to treat digital assets as financial products and apply a 20% flat tax on gains. These developments show the country’s ongoing efforts to formalize and expand its digital asset environment.
