Major mining market player Bitdeer has announced the launch of a new bitcoin mining project that will be fully powered by wind energy. Facilities with a total capacity of 28 MW will be deployed at Soluna's wind energy site in Texas, known as Kati 1. This strategic decision will allow the company to add approximately 1.93 EH/s to its hash rate.
Synergy of renewable energy and cryptocurrency mining
Equipment installation will begin as early as September and will occur in stages. The key feature of the project is its energy foundation. The Kati 1 data center is connected directly to the Las Majadas wind farm, which has a total capacity of 83 MW. This approach allows the use of "green" energy directly, avoiding transmission losses and reducing the carbon footprint.
Bitdeer will provide its own ASIC miners, the Sealminer A2 Pro Air, for the project, while Soluna will take on operational management and electricity supply. Mining revenues will be split between the partners, although the financial details and terms of the agreement remain undisclosed.
Scale and prospects
After full deployment of the capacity, Bitdeer plans to add a significant 1.93 EH/s to its hash rate. At the same time, the potential of the Kati 1 site is much higher: Soluna previously estimated the project's total capacity at 3.5 EH/s. This suggests that the partnership is long-term in nature and provides for further expansion.
For Soluna, this deal is not just a way to monetize excess energy. The company is building infrastructure directly at energy sources, using it for bitcoin mining, and in the future — for AI and HPC segments. The second phase of the Kati project is already designed for more than 100 MW of AI/HPC infrastructure, demonstrating a clear trend toward diversification.
Market trends: miners are moving into AI
Against this backdrop, Bitdeer continues to strengthen its position. As of June 30, the company's operational hash rate reached 73 EH/s, increasing by more than 340% over the past 12 months. This allowed it to overtake longtime leader MARA, while other public miners, by contrast, are reducing their capacity. Excluding Bitdeer, public miners have reduced realized hash rate by 21% since the fourth quarter of 2025.
Bitcoin mining difficulty, meanwhile, is stagnating. On August 23, it decreased by 1.3% — to 125.81 T, returning to the level of mid-February. The seven-day moving average of the network hash rate stands at 867.4 EH/s, showing a downward trend since October 2025, when at the peak of bitcoin's price this figure reached 1.15 ZH/s.
The migration to AI is becoming increasingly evident. In the first half of 2026, 15 public bitcoin miners and AI infrastructure operators invested $30.7 billion in equipment — 42.6% more than in all of 2025. Nine cryptocurrency miners grew their revenue from HPC, AI cloud, and colocation by 52% in the second quarter — to $205.8 million. TeraWulf, for example, received regulatory approval for power supply to the Justified Data Campus data center with a capacity of 482 MW under a 20-year contract with Anthropic, which will bring the company approximately $19 billion in revenue.
My view: The Bitdeer and Soluna deal is not just an attempt to reduce costs, but a strategic move amid growing pressure from ESG factors. The use of renewable energy is becoming a key competitive advantage, especially against the backdrop of an active flow of capacity into the AI sector. However, investors need to understand: while miners diversify, the bitcoin market may face a further decline in hash rate, which in the medium term could affect mining difficulty and profitability.
