WILLACY COUNTY, TEXAS — In an aggressive display of confidence amid a volatile macroeconomic and digital asset landscape, green data center developer Soluna Holdings and high-performance crypto infrastructure giant Bitdeer Technologies Group have announced a significant expansion of their ongoing collaboration. Announced on September 28, the latest agreement adds an additional 7 megawatts (MW) of mining capacity to Project Kati 1, located in the wind-rich expanse of South Texas.
This swift expansion—executed before the original deployment has even reached its operational finish line—brings Bitdeer’s total footprint at the facility to a robust 35 MW. It effectively fully subscribes the K1BC phase of Project Kati 1, meaning that all available power and rack allocations designated for this specific section of the data center have now been completely claimed.
The deal underscores a broader, structural evolution within the digital asset mining sector: a shift away from rigid, traditional colocation hosting models toward dynamic, profit-sharing co-mining partnerships designed to maximize efficiency, leverage stranded or curtailed renewable energy, and weather the cyclical storms of Bitcoin network economics.

Chronology of the Partnership
The speed at which this relationship has evolved highlights both the operational agility of both companies and the urgent demand for high-efficiency, power-secured data center real estate in North America.
August 2023: The Initial Handshake
The foundation for the alliance was laid just weeks prior, in August, when Soluna and Bitdeer formally announced their initial agreement. That foundational pact established a 28 MW deployment at Project Kati 1. At the time, the deal was celebrated as a major win for Soluna’s green-focused infrastructure model, providing a reliable, tier-one anchor tenant capable of consuming significant blocks of power.
September 2023: The Accelerated Expansion
In a move that caught many industry observers by surprise, the partners moved to scale the project before the initial ink on the 28 MW deployment had even dried. On September 28, Soluna publicly disclosed that Bitdeer would up the ante by another 7 MW. This rapid iteration transformed a standard infrastructure agreement into a deeper strategic alliance. By expanding the deployment to 35 MW, the partners demonstrated that the preliminary performance metrics, site reliability, and localized power economics exceeded initial expectations, prompting an immediate greenlight for scaling.
November Target: Operationalization
Looking ahead, the current timeline dictates a rapid deployment phase. Engineering and operations teams on the ground in Willacy County are racing toward a November completion target for the 7 MW addition, ensuring that the Sealminer A2 Pro Air units are integrated seamlessly alongside the previously slated hardware to achieve the targeted 2.42 EH/s hash rate threshold.
Supporting Data and Technical Architecture
To fully comprehend the significance of the Soluna-Bitdeer expansion, one must examine the underlying mechanics of Project Kati 1 and the broader technological ecosystem that supports it.
Project Kati 1 Specifications
Project Kati 1 is an 83 MW modular data center facility situated in Willacy County, Texas. Its strategic value lies in its geographical and electrical positioning: it is tightly interconnected with local wind generation assets.
Texas’s Electric Reliability Council of Texas (ERCOT) grid is notoriously prone to localized congestion and over-generation, particularly during periods of high wind output when demand falls short. When this occurs, wind farms face curtailment—meaning turbines are intentionally shut down or powered off because the grid cannot absorb the electricity. Soluna’s business model is explicitly designed to solve this economic inefficiency. By placing energy-intensive computing loads directly adjacent to these underutilized renewable sources, Soluna acts as a localized "buyer of last resort," transforming wasted green electrons into economically viable digital assets.
The Power of the Sealminer A2 Pro Air
Bitdeer’s choice of hardware for the expansion—the Sealminer A2 Pro Air—reflects the industry’s relentless pursuit of electrical efficiency (measured in joules per terahash, J/TH). As Bitcoin mining difficulty scales upward and block rewards decline following the halving events, operators cannot afford to run legacy machines that consume excess power. The Sealminer units represent Bitdeer’s vertical integration strategy, pushing proprietary silicon into the market to compete directly with established ASIC manufacturers while optimizing hash rate output per megawatt consumed.
Official Responses and Strategic Vision
While public disclosures have outlined the operational parameters of the deal, statements from executive leadership provide vital context regarding the long-term motivations driving the expansion.
Soluna’s executive team has consistently framed these agreements not merely as real estate leases, but as pioneering steps toward the industrialization of "green computing." By aligning data center operations directly with renewable energy curtailment zones, Soluna insulates its partners from traditional, fossil-fuel-dependent utility price spikes while offering local grid operators a flexible load resource that can be throttled down instantly if grid demand peaks.
From Bitdeer’s perspective, the collaboration represents a capital-efficient method of scaling operations. Building a massive, utility-scale data center from the ground up requires immense capital expenditure, complex permitting processes, and lengthy interconnection queues. By partnering with Soluna, Bitdeer bypasses years of bureaucratic delay and construction friction, gaining immediate access to turnkey power and operational infrastructure in one of the world’s most favorable regulatory jurisdictions for cryptocurrency mining: Texas.
Furthermore, the co-mining structure aligns the fortunes of both firms. When Bitcoin prices surge or network difficulty drops, both companies reap the rewards. Conversely, during periods of market compression, the risk is shared, fostering a resilient, long-term alignment of interests that a rigid fixed-fee hosting model simply cannot replicate.
Implications for the Industry
The Soluna-Bitdeer expansion at Project Kati 1 carries profound implications for the broader Bitcoin mining and green energy sectors, signaling trends that will likely shape the industry for years to come.
1. The Death of the Rigid Hosting Model?
For years, the Bitcoin mining sector relied heavily on a straightforward bifurcated model: hosters built data centers and charged miners a flat, fixed rate per kilowatt-hour (kWh) for power and space, regardless of whether the miner was profitable or whether the Bitcoin network was booming or crashing.
This model frequently resulted in catastrophic defaults when bear markets struck and mining margins compressed below the fixed hosting costs, leaving data center operators holding empty racks and unpaid utility bills. Soluna’s co-mining model—where infrastructure providers take direct exposure to Bitcoin via revenue-sharing—represents a maturation of the market. It creates a true partnership where risk and reward are mutually distributed, paving the way for more resilient commercial structures across the sector.
2. The Convergence of High-Performance Computing (HPC) and Crypto
While Bitcoin mining remains the foundational anchor workload for facilities like Project Kati 1, Soluna has increasingly positioned its sites to accommodate alternative forms of high-performance computing, including artificial intelligence (AI) and machine learning workloads.
The modular infrastructure deployed in South Texas is designed with flexibility in mind. As the global demand for AI compute skyrockets, data center developers possessing grid-interconnected power and renewable energy integration expertise find themselves in an enviable position. The infrastructure built for Bitcoin mining today can, with minor adjustments, serve as the foundational bedrock for the next generation of compute-heavy technologies.
3. Texas as the Global Epicenter of Green Crypto
The rapid expansion of Project Kati 1 further cements the Lone Star State’s status as the uncontested capital of global Bitcoin mining. Favorable regulatory environments, pro-business policies, and vast expanses of rural land paired with massive wind and solar installations make Texas the premier destination for capital deployment in the digital asset space. However, as the Kati 1 expansion demonstrates, success in Texas requires sophisticated navigation of grid dynamics, curtailment realities, and environmental integration.
4. A Vote of Confidence Amid Macro Uncertainty
Finally, the sheer velocity of this expansion—scaling up by 7 MW just weeks after the initial 28 MW agreement—sends a powerful psychological signal to the market. Amid fluctuating macroeconomic indicators, regulatory scrutiny, and the post-halving economic squeeze, major industry players are still willing to deploy millions of dollars in cutting-edge hardware. For Bitdeer and Soluna, the bet is clear: secure the power, deploy the best hardware, integrate with renewables, and scale aggressively.
As the November completion date for the Kati 1 expansion approaches, all eyes will be on Willacy County to see how the 2.42 EH/s hash rate performs in the wild. If successful, the Soluna-Bitdeer blueprint may well become the standard template for how digital infrastructure, renewable energy, and Bitcoin mining converge in the decades ahead.
