<<Deep Dive>> Can Mining Firm Canaan Contribute to Japan's Power Grid Stability? Technical Advantages and the Real Barriers to Market Entry

From the Perspective of Power Systems Engineering:
The Strategic Value of Bitcoin Mining

This article provides a detailed analysis of the 4.5 MW water-cooled mining server sales contract signed by Canaan Inc. (hereinafter "Canaan") with a Japanese electrical engineering solutions provider in October 2025, examining its technical advantages, the technical levels of competitors, and the complex barriers to market entry from the professional perspectives of power systems engineering and geopolitics.

Traditionally, Bitcoin mining has been viewed merely as a power consumer. However, as the integration of renewable energy expands and the importance of power grid stabilization (ancillary services) increases, the ability to adjust mining loads quickly and flexibly is creating new strategic value.

Canaan's contract symbolizes this paradigm shift, and it should be evaluated not merely as a product sale, but as the provision of a solution that contributes to improving the resilience of the power grid.

Canaan's Technical Advantages:
Evaluation of Precision Demand Response (DR) Capabilities

The Avalon A1566HA-488T water-cooled mining server provided by Canaan has a clear advantage over competitor products, particularly in demand response (DR) capabilities, which are essential for power grid stabilization.

✅️Controlled Overclocking/Underclocking Technology

The core of Canaan's solution is its "controlled overclocking/underclocking" capability, powered by proprietary smart control chips and advanced feedback algorithms.

• Adjustment Granularity

  • Canaan:
    Continuous and fine-grained. Dynamically adjusts frequency, voltage, and hash rate.

  • Conventional:
    Discrete. ON/OFF for the entire miner or parts of it.

• Adjustment Speed

  • Canaan:
    Real-time. Reacts instantly to fluctuations in the power grid.

  • Conventional:
    Response times in the range of seconds to minutes.

• Contribution to the power grid

  • Canaan:
    Optimal for frequency regulation. Maintains the balance between power supply and demand with extreme precision.

  • Conventional:
    Primarily provides reserve capacity. Responds to large-scale supply-demand gaps.

• Mining profitability

  • Canaan:
    Since it does not completely cut off the load, it balances maintaining profitability with contributing to the power grid.

  • Conventional:
    Revenue is zero during load shedding.

In power systems engineering, frequency regulation is the service that requires the fastest response speed to maintain grid health. Canaan's technology is by adjusting miner power consumption in millisecond increments, a sophisticated grid stabilization solution that enables participation in high-precision ancillary services, such as tertiary and primary regulation in Japan's supply-demand adjustment market, setting it apart from general DR that simply stops and restarts miners.

⚡️Competitor technical levels

While major competitors also offer water-cooled miners, Auradine in the U.S. is a company that puts forward a solution comparable to Canaan's DR integration technology.

• Bitmain/MicroBT

  • They offer water-cooled miners (such as the Antminer S21 Hydro and WhatsMiner M66S++), and these devices can also participate in DR programs. However, their control relies primarily on external aggregators or fleet management software. In terms of autonomous and precise grid response capabilities via a "smart control chip" embedded in the miner itself, Canaan likely has the upper hand.

• Auradine

  • With its EnergyTune technology and FluxVision software, it achieves rapid energy demand response while minimizing hashrate loss during DR events. Canaan and Auradine stand apart from traditional manufacturers in that they are expanding their business scope from mining equipment manufacturers to energy solution providers.

Conclusion: While competitors are on par in terms of hardware (water cooling), the integration of software and control chips that enables advanced coordination with the power grid serves as a technical barrier to entry that sets Canaan apart from the rest.

Comprehensive Assessment of Barriers to Entry

　Canaan's entry into the Japanese market is analyzed as the result of overcoming not only technical advantages but also the following complex non-technical barriers to entry.

🎙️Political/Geopolitical Barriers to Entry:
National Security and Supply Chain

　The fact that Canaan is a Chinese company acts as a barrier to entry, especially in contracts involving critical infrastructure like the power grid, but they have managed to overcome this hurdle first.

National Security Concerns
　In the United States, it has been pointed out that Chinese-made mining equipment could potentially be used as a backdoor for espionage or cyberattacks. The U.S. government has been strengthening its vigilance, such as by issuing executive orders prohibiting Chinese companies from acquiring land near military bases (e.g., the CFIUS case).
　Japanese power companies cannot ignore this geopolitical risk. Connecting Canaan's equipment to the power grid carries dual risks: cybersecurity and power supply stability. The background to this contract being finalized suggests that Canaan's technical superiority was valued enough to outweigh this geopolitical risk, or that Japanese partner companies have implemented robust security measures.

Supply Chain Risk
　Due to trade friction between the U.S. and China (tariffs, export controls), Chinese manufacturers including Canaan are showing moves to relocate production bases to countries like the U.S. If the Chinese government strategically restricts the export of mining equipment, long-term supply stability could be threatened.
　For Japanese power companies, the stable supply of equipment in long-term contracts is extremely important. By demonstrating transparency through its NASDAQ listing and its commitment to the Japanese market, Canaan is partially mitigating this supply chain risk.

Public Offering (IPO)
　Canaan is listed on the NASDAQ, and its financial information and management transparency are higher than those of private companies. Since major clients like power companies prioritize corporate viability and transparency in long-term partnerships, going public functions as proof of reliability. This serves as a significant barrier to entry against unlisted competitors.

Regulatory/Market Structure Barriers to Entry:
The Uniqueness of Japan's Power Market

　Canaan's contract is the result of understanding and adapting to the unique regulatory environment and market structure of Japan's power market. Establishing a bridgehead is a very significant achievement.

Requirements for Entry into the Supply-Demand Adjustment Market
　Japan's supply-demand adjustment market (ancillary services market) imposes strict response speed and accuracy requirements on resources that contribute to power grid stabilization. In particular, participation in frequency regulation services (Tertiary Adjustment Power ②, Primary Adjustment Power) requires precise control technology like Canaan's "controlled overclocking/underclocking." Mining operators that cannot meet these technical requirements are unable to enter the market at all.

Trust with Power Companies
　The Japanese power market is closed to new entrants, and contracts involving grid operation, in particular, require years of track record and trust. Canaan was able to win the contract not just because of equipment performance, but because its strong collaboration with Japanese partners and past overseas demonstration experience were highly valued.

Religious Barriers to Entry:
Looking Ahead, Suitability for Islamic Finance

　In Middle Eastern markets, including Saudi Arabia, religious barriers to entry are extremely important.

Sharia Compliance (Halal Certification)
　In the Islamic world, whether a Bitcoin mining business is compliant with Sharia (Islamic law) is a prerequisite for large-scale investment and business development. Mining itself is generally considered Halal (permissible) because it does not involve the generation of interest (riba) and has few speculative elements that do not involve the real economy tends to be the view.
　However, the final judgment is left to the religious authorities of each country, and obtaining Sharia compliance certification becomes a significant barrier to entry for large-scale business operations in the Middle East market. The background to Canaan not having secured contracts in Saudi Arabia may be influenced by delays in addressing this Sharia compliance or market uncertainty.

Conclusion:
Canaan's Strategic Position and Future Outlook

　Canaan Inc.'s contract in Japan clearly demonstrates that the company is evolving from a mere hardware manufacturer into an energy solution provider that contributes to the stabilization of the power grid.

1. Technical Advantage: While competitors are following suit with hardware (liquid cooling), Canaan has established a barrier to entry in the high-value ancillary services market—specifically frequency regulation for power grids—through precise DR integration technology (controlled overclocking/underclocking).

2. Overcoming Non-Technical Barriers to Entry: Despite the geopolitical risks associated with being a Chinese company, Canaan has successfully entered the Japanese power market—a sector characterized by extremely strict regulations and a high emphasis on reliability—by leveraging the transparency of its NASDAQ listing and providing advanced technical solutions.

3. Future Outlook: This success story in Japan serves as a powerful sales tool for other developed nations where power grid stabilization is an urgent issue (particularly in Europe and North America, where the adoption of renewable energy is progressing). Meanwhile, expansion into the Middle Eastern market will require addressing Sharia compliance and building geopolitical trust, which will be the keys to future growth.

I judge that this contract can be evaluated as an extremely strategic step that foresees a future where Bitcoin mining becomes an indispensable presence as a 'balancing capacity' for power grids.
