As the global Bitcoin mining landscape evolves, one of the most promising developments is unfolding in Kotka, Finland — where a state-of-the-art mining facility is rapidly expanding to meet growing demand. With geopolitical shifts, regulatory changes, and energy efficiency becoming central to mining operations, Finland has emerged as a strategic hub for sustainable and scalable Bitcoin mining.
This article explores the transformation of the global hashrate distribution, Finland’s favorable regulatory and energy environment, and the progress of the KOTKA Bitcoin mining facility — one of Northern Europe’s most advanced mining sites.
Global Bitcoin Mining Landscape: A Post-China Shift
As of mid-2023, over 8 million Bitcoin mining machines were actively contributing to the network's computational power worldwide. Just two years prior, in May 2021, China dominated the ecosystem, accounting for 75% of global Bitcoin hashrate, with more than 6 million miners operating across regions like Sichuan and Inner Mongolia.
However, tightening regulations led to a mass exodus. By the end of 2022, over 70% of Chinese mining machines had been shut down, with operators relocating equipment to jurisdictions offering stable policies and affordable energy. Countries such as the United States, Kazakhstan, Russia, and Nordic nations like Finland have since absorbed much of this displaced capacity.
Today, the decentralization of Bitcoin mining is more evident than ever — and Finland is positioning itself as a key player in this new era.

Why Finland? Regulatory Clarity and Energy Advantage
Finland offers a rare combination: regulatory clarity, cold climate, and abundant clean energy — making it ideal for energy-intensive Bitcoin mining.
Cryptocurrency Regulation in Finland
The Finnish government recognizes Bitcoin and other cryptocurrencies as legitimate financial instruments. While not legal tender, Bitcoin payments are accepted by many businesses and taxed based on market value at the time of transaction.
Financial institutions regulated by the Bank of Finland may provide banking services to cryptocurrency exchanges and custodial wallet providers — a level of institutional support that fosters trust and stability.
There is no specific licensing requirement for Bitcoin miners. As long as operators comply with standard business regulations — including electricity use and income tax obligations — mining is fully legal.
Tax Environment for Miners
Finland applies a favorable tax model for small enterprises:
- 1–3% tax on business profits
- 5% dividend tax (if profits are distributed)
- No additional levies on cryptocurrency mining income
This streamlined structure reduces compliance complexity and improves net returns — a significant advantage over jurisdictions with ambiguous or punitive crypto taxation.
Finland’s Energy Infrastructure: Powering Sustainable Mining
Bitcoin mining requires massive amounts of electricity. Finland’s northern location provides natural cooling, reducing operational costs significantly. But more importantly, its energy grid supports large-scale industrial usage with sustainability in mind.
The national grid integrates hydro, nuclear, and wind power, offering miners access to low-cost, carbon-efficient electricity. In Kotka specifically, industrial-grade power is readily available, with minimal transmission loss due to proximity to substations.
For mining operators, this means:
- Lower cooling costs
- Stable power supply
- Eligibility for grid incentives
Grid Reward Program: Finnish transmission system operator Fingrid offers annual rewards of 5–15% off total electricity bills for businesses that utilize 95% or more of their contracted power capacity — a strong incentive for high-efficiency mining farms.
Introducing the KOTKA Bitcoin Mining Facility
Located just 200 kilometers from Helsinki and only 3 kilometers from the E18 highway, the KOTKA Bitcoin mine is strategically positioned for logistics and connectivity.
Operated by Oy Green Nordic Data Service Ltd (GNDS), the facility spans 22,000 square meters, with 10,000 square meters dedicated to containerized mining rigs. It currently has 20 megawatts (MW) of power connected, scalable up to 100 MW in phases — enough to support over 33,000 high-performance ASIC miners.
Key Features:
- Proximity to a major substation (only 100 meters away) ensures stable power delivery
- Full fiber-optic internet connectivity for low-latency block propagation
- 24/7 video surveillance and on-site security team
- Modular design allows rapid deployment and expansion
The first phase (20 MW) is already operational, with GNDS having signed a comprehensive hosting agreement with Bitmain, one of the world’s leading ASIC manufacturers. The facility will host Bitmain Antminer S19 models (140 TH/s and above), known for their high efficiency and reliability.
Full deployment of over 33,000 units is expected by May 2024, marking a major milestone in Nordic mining infrastructure.
Economic Viability: How Profitable Is Mining in Finland?
Bitcoin mining profitability hinges on three core factors: electricity cost, hardware efficiency, and network difficulty. In Finland — especially at the KOTKA site — these variables align favorably.
Electricity Cost & Profit Margin
Current industrial electricity rates in Kotka average around €0.015 per kWh — among the lowest in Western Europe. When Bitcoin trades above $40,000, profit margins expand significantly, pushing effective electricity costs even lower due to:
- High hash price environment
- Grid utilization rebates (up to 15%)
- Low maintenance costs (thanks to cold climate)
This creates a compelling economic model for both hosted clients and self-operated mining pools.
Revenue Diversification: Selling Hashpower
Beyond direct mining rewards, GNDS plans to offer global investors access to fractional hashpower. This allows individuals and institutions to participate in Bitcoin mining without managing physical hardware.
Benefits include:
- Transparent performance reporting
- Payouts in BTC or EUR
- Exposure to long-term Bitcoin appreciation
Such models are gaining traction as more users seek passive income streams tied to digital asset growth.

Frequently Asked Questions (FAQ)
Q: Is Bitcoin mining legal in Finland?
A: Yes. There are no specific bans or licensing requirements for cryptocurrency mining. As long as miners comply with standard business and tax laws — including paying income tax and using legal electricity sources — mining is fully permitted.
Q: What makes Finland a good location for Bitcoin mining?
A: Finland offers cool climate (reducing cooling costs), reliable clean energy, political stability, strong internet infrastructure, and clear financial regulations — all critical for efficient and sustainable mining operations.
Q: How much does it cost to run a miner in the KOTKA facility?
A: Electricity costs start at approximately €0.015/kWh. Hosting fees vary depending on contract size and duration but are competitive within the European market due to scale and incentives.
Q: Can foreign companies host miners in Finland?
A: Absolutely. The KOTKA facility welcomes international clients. GNDS provides full support for logistics, customs clearance, installation, monitoring, and maintenance.
Q: Are there environmental concerns with large-scale mining in Finland?
A: The Finnish grid relies heavily on non-fossil energy sources (over 80% carbon-free), minimizing environmental impact. Additionally, waste heat from miners is being explored for district heating projects in some areas.
Q: When will the full 100 MW capacity be online?
A: The project is being developed in three phases. While Phase 1 (20 MW) is active, full buildout to 100 MW will depend on market demand and equipment availability, likely completed by late 2025.
The Future of Nordic Mining
The rise of the KOTKA facility reflects a broader trend: the migration of Bitcoin mining toward colder, energy-rich, and regulation-friendly regions. As environmental, social, and governance (ESG) considerations gain importance, Nordic countries are setting the standard for responsible mining practices.
With continued investment in infrastructure, renewable integration, and digital finance innovation, Finland is not just hosting miners — it’s helping shape the future of decentralized networks.
