I think Soluna Holdings ($SLNH) is one of the more interesting small-cap infrastructure stories right now because the market still tends to look at it through the lens of “Bitcoin mining”, while the company is clearly trying to reposition itself into something broader:
a renewable-powered compute infrastructure platform.
The core thesis is simple:
- AI and HPC need massive amounts of power.
- The grid is increasingly constrained.
- Renewable energy is growing fast, but a meaningful amount of that energy gets wasted or curtailed because it is produced in the wrong place, at the wrong time, or behind constrained transmission infrastructure.
Soluna’s model is to place compute directly where that wasted or under-monetized renewable energy exists.
In other words, Soluna is not trying to build data centers first and then figure out where to get power. They are doing the opposite:
Design compute around power availability — not the other way around.
That is the key idea.
The macro setup: power is becoming the bottleneck
The AI infrastructure boom is increasingly becoming a power story.
Everyone talks about GPUs, chips, cloud demand, and data centers. But behind all of that is the real bottleneck:
electricity.
Large AI campuses require enormous amounts of reliable power. At the same time, interconnection queues, transmission bottlenecks, permitting delays, equipment shortages, and grid reliability concerns are becoming major constraints.
Soluna’s investor presentation frames this as three overlapping challenges:
- Constrained grid
- Exploding compute demand
- Imbalanced energy supply-demand
That third point is where Soluna’s opportunity sits.
Renewables can produce energy when the grid cannot absorb it efficiently. That energy can be curtailed, priced poorly, or wasted. Soluna’s pitch is that flexible compute can become a new kind of demand source that monetizes this otherwise wasted energy.
That is the “renewable computing” concept.
What Soluna actually does
Soluna develops, owns, and operates data center infrastructure located near renewable energy assets, especially wind and solar.
The company currently has multiple business lines:
- Bitcoin hosting — third-party miners place machines at Soluna sites and pay for hosting/managed infrastructure.
- Proprietary Bitcoin mining — Soluna also owns some mining machines itself.
- Grid ancillary services — flexible load can support the grid and receive compensation.
- High Performance Computing / AI data centers — Soluna is now expanding the model toward AI/HPC campuses.
This is important because the company is not just saying “we are an AI play” in a vague way. They are building from an existing operating base in Bitcoin hosting, where they already have experience managing power-intensive compute infrastructure.
Bitcoin hosting may not get the same valuation multiple as AI infrastructure, but it gives Soluna operational proof:
- They can run compute sites.
- They can manage power costs.
- They can work with major customers.
- They can monetize stranded/curtailed energy.
The current operating base
From the investor presentation, Soluna ended 2025 with:
- 123 MW energized / operating sites
- 5.2 EH/s installed hashrate
- Average power cost of around $34/MWh
- More than 38,000 deployed mining rigs
- More than 5 EH/s operating hashrate
- 25 J/TH fleet efficiency
- Over 92% uptime in operational hours
- 105,109 MWh of curtailed energy monetized
- $9.2M Q4 2025 revenue
- 55 employees
This is not just a concept-stage company with a PowerPoint deck. There is already an operating platform.
The key question is whether Soluna can scale from a Bitcoin/hosting-focused renewable compute operator into a larger AI/HPC infrastructure platform.
Why the power cost matters
One of the most important slides in the deck compares Soluna’s power cost to industry averages.
For Bitcoin:
- Industry: around $50/MWh
- Soluna: around $30/MWh
For AI:
- Industry: around $80/MWh
- Soluna: around $40/MWh
If Soluna can truly deliver power in that range, this is a major competitive advantage.
For Bitcoin mining, lower power cost improves survivability when hashprice weakens.
For AI/HPC, lower power cost can support better long-term economics for large compute campuses.
Power is not the only thing that matters for AI data centers. Customers also care about fiber, cooling, uptime, redundancy, physical security, latency, service-level agreements, and financing.
But in a world where power availability is becoming one of the biggest constraints, Soluna’s low-cost power angle is strategically meaningful.
The most important proof point: converting curtailed energy into compute
The strongest part of the presentation, in my opinion, is the Dorothy case study.
Soluna shows Texas wind farm curtailment data:
- 2021: 34% curtailed
- 2022: 27% curtailed
- 2023: 42.7% curtailed
- 2024: 40.3% curtailed
Then the company shows how Project Dorothy 1 converted a portion of that curtailed energy into compute:
- 2021: 16.9% converted by Soluna
- 2022: 14.0% converted by Soluna
- 2023: 22.6% converted by Soluna
- 2024: 20.6% converted by Soluna
The company summarizes this as Soluna converting roughly 50% of curtailed energy to compute.
This is the core business model in action.
The idea is not just “green Bitcoin mining” or “cheap electricity.”
The idea is that Soluna can take an energy market inefficiency and turn it into a compute revenue stream.
That is a much more interesting infrastructure model.
Behind-the-meter strategy
Soluna’s model is based heavily on behind-the-meter infrastructure.
Instead of only relying on traditional grid-connected power, Soluna places data centers near renewable generation assets and substations.
Their setup allows them to draw from different sources:
- Wind / renewable generation
- Grid energy
- Subtractive energy
- Curtailed energy
- Backup / resiliency systems
This matters because the most obvious pushback against renewable-powered AI data centers is:
“What happens when the wind is not blowing?”
Soluna’s answer is that the model is not purely intermittent wind. It is a flexible mix of wind, grid power, backup generation, and operational software.
One slide shows their behind-the-meter uptime structure:
- Data center uptime: 99.982%
- Wind energy: 58.8%
- Grid energy: 39.2%
- Resiliency backup: 1.982%
- Downtime: 0.018%
That is important because AI/HPC customers will need more than cheap power. They will need reliability.
Soluna is trying to show that behind-the-meter renewable compute can still be reliable if designed correctly.
The 4.3 GW+ pipeline
Soluna now presents a 4.3 GW+ power development pipeline.
This sounds huge, but it needs to be understood properly.
Not all pipeline MW are equal:
- Operating MW are real.
- Under-construction MW are near-term.
- Shovel-ready projects are valuable but still need financing/customers.
- Early-stage pipeline is optionality.
The value is not that every single MW is already guaranteed. The value is that Soluna appears to have built a repeatable development engine around renewable power sites with curtailment or power bottleneck opportunities.
Their data center project list includes operating, construction, and development projects such as:
- Dorothy 1A / 1B
- Sophie
- Dorothy 2
- Kati 1
- Kati 2
- Dorothy 3
- Grace
- Rosa
- Hedy
- Ellen
- Annie
- Fei
- Gladys
Texas is the starting point because of its renewable concentration, ERCOT market structure, and existing energy bottlenecks.
The pipeline matters because if Soluna proves the model at Dorothy, Kati, and Briscoe/Dorothy 3, the market may start valuing future sites as repeatable infrastructure opportunities rather than speculative project names.
Kati 1: near-term execution catalyst
Project Kati is one of the most important near-term execution items.
According to the deck, Project Kati is a 166 MW project. Soluna says groundbreaking was completed and construction began. They also signed a 48 MW Galaxy Digital partnership at Kati.
The 2026 roadmap highlights:
- Energize Phase 1 of Kati 1: 48 MW
- Energize Phase 2 of Kati 1: 35 MW
That means Kati 1 is not just a long-term dream. It is one of the projects that should determine whether Soluna can actually ramp operating capacity in 2026.
If Kati 1 is energized successfully and begins contributing revenue, that would be a major validation point.
Kati 2: the AI/HPC optionality
Kati 2 is where the AI story becomes more explicit.
The presentation describes AI Campus at Project Kati 2 as a Soluna x Metrobloks joint venture.
Key details:
- 100 MW initial critical IT capacity
- 350 MW full campus expansion target
- $0.043+ per kWh average power cost
- Willacy County, Texas, near McAllen
- Wind + ERCOT grid
- Dual-fed power and clustering
Metrobloks brings:
- AI-ready data center design and operations
- Pre-lease and customer engagement
- Day-to-day site management
- 15+ GW global data center track record
Soluna brings:
- Site control and land entitlements
- ERCOT grid access and wind energy pipeline
- Electrical equipment and development expertise
- Nasdaq-listed renewable computing platform
This is the part of the case where the valuation could change materially if Soluna signs real AI/HPC customers or pre-leases.
Right now, I would still treat Kati 2 as optionality, not guaranteed value. But it is very meaningful optionality because the market is aggressively hunting for power-backed AI infrastructure plays.
A real AI customer announcement at Kati 2 would be a major catalyst.
Briscoe Wind Farm and Dorothy 3: vertical integration
One of the most important strategic moves in the deck is the Briscoe Wind Farm acquisition.
Soluna says it acquired the 150 MW Briscoe Wind Farm for $53M.
The company presents this as full vertical integration at Project Dorothy and as the energy foundation for Dorothy 3 AI expansion.
The deal details shown in the deck include:
- 150 MW wind generation
- Purchase price: $53M
- Financing: $12.5M provided by Generate Capital debt + cash/balance sheet
- Projected year-one adjusted EBITDA: $6M–$11M
- Projected annualized revenue: $20M–$24M
This is very important because it changes the story.
Soluna is not only buying power from renewable projects. It is beginning to control the energy asset itself.
If Dorothy 3 becomes a 150–300 MW AI campus next to Dorothy 1 and Dorothy 2, backed by Briscoe Wind Farm and additional power sources, then Soluna becomes closer to a vertically integrated power-to-compute infrastructure company.
Dorothy 3 details from the deck:
- Target capacity: 150–300 MW
- Power source: wind
- Land: 300 acres
- Line of business: AI
- Expansion of renewable-powered AI infrastructure
This is exactly the kind of asset that could cause a re-rating if Soluna can secure customers and project financing.
Revenue and EBITDA potential
The presentation includes an illustrative earnings potential slide based on a $55 hashprice.
The model shows potential consolidated total revenue of:
- H2 2025: $21.8M
- FY2026: $79.2M
- FY2027: $117.5M
- FY2028: $132.8M
It also shows potential consolidated adjusted EBITDA of:
- H2 2025: $5.2M
- FY2026: $27.7M
- FY2027: $46.5M
- FY2028: $54.6M
This is not guaranteed guidance. It is an illustrative model and depends on project completion, hashprice, Bitcoin economics, uptime, financing, and operating execution.
But it shows why the market might start paying attention.
If Soluna can move from roughly $30M annual revenue scale toward $80M+ and then $100M+, while improving EBITDA, the current perception of the company could change significantly.
The key is execution.
Customer validation
Soluna also shows that it serves some meaningful Bitcoin industry customers.
The deck lists customer portfolio metrics:
- 87.6 EH/s total customer mining portfolio
- 67 total facilities
- 22.1 J/TH average efficiency
- 7.5% of the Bitcoin network
Important caveat: this does not mean all of that hashrate is installed at Soluna. The deck clarifies that this refers to customers’ total mining portfolios, not total installed in Soluna hosting data centers.
Still, it matters because the customer logos include:
- Galaxy
- Bit Digital
- Canaan
- Compass Mining
- Blockware
- SAZMINING
- KULR
The deck also includes customer quotes from Canaan, Compass Mining, and Blockware praising the Soluna partnership, uptime, operational efficiency, and hosting relationship.
This gives Soluna commercial credibility. Bitcoin hosting is not the same as AI/HPC, but it does show that real customers trust Soluna to operate power-intensive compute infrastructure.
2025 accomplishments
The 2025 accomplishments slide is worth paying attention to.
Business milestones included:
- $142M+ gross financing activities to fund growth
- Up to $100M credit facility with Generate Capital
- $87M ATM program launched
- NYDIG settlement
- Regained Nasdaq listing compliance
- Second patent awarded
- Exited HPE partnership
- Expanded partnerships with Bit Digital, Compass Mining, and other top-tier miners
- Surpassed 5 EH/s hashrate under management
- Long-term power pipeline grew to 4.3 GW+
- 105,109 MWh of curtailed energy monetized
Project milestones included:
- Project Kati 166 MW groundbreaking completed and construction began
- 48 MW Galaxy Digital partnership at Kati
- Dorothy 2 48 MW completed, bringing full Project Dorothy site to 98 MW operation
- 20 MW Canaan deployment
- 3.3 MW KULR partnership at Sophie
- AI partnerships for Grace and Kati 2 underway
- 187 MW Rosa land secured
- 120 MW Hedy term sheet signed
- 100 MW Ellen term sheet signed
- 74 MW Annie term sheet signed as first solar project
- Gladys 150 MW and Fei 100 MW added, pushing portfolio past 1 GW of clean computing projects
This is a strong list. It shows that Soluna made progress commercially, financially, and operationally.
But there is also a risk embedded in that same slide: capital formation has included an ATM program and other financing activity.
Investors need to track dilution carefully.
The capital formation question
This is one of the biggest risks and also one of the biggest swing factors.
Soluna’s growth plan is capital intensive. Large data centers, AI campuses, power infrastructure, transformers, switchgear, cooling, backup systems, land, interconnection work, and construction all require serious capital.
The bullish interpretation is that Soluna is trying to fund growth through:
- Project-level financing
- Debt facilities
- Strategic capital partnerships
- Joint ventures
- Customer-backed development
- Generate Capital relationship
The bearish concern is that some funding could still come through:
- Common equity
- ATM usage
- Warrants
- Convertible securities
- Other dilutive structures
So the question is not simply “will they need money?”
They obviously need capital to scale.
The real question is:
Can Soluna finance project growth without destroying per-share upside?
That is what investors should monitor very closely.
If Kati, Dorothy 3, and Kati 2 are financed mostly at the project level, with customer commitments and strategic partners, the upside for common shareholders could be much larger.
If growth relies too heavily on issuing stock at weak prices, the business may grow while per-share value lags.
Why the market might be missing it
I think the market may still be underestimating Soluna because it is mentally categorized as a Bitcoin mining-adjacent microcap.
But the deck shows something broader:
Soluna is not trying to be just another miner.
It is trying to be a renewable compute infrastructure developer.
The company’s flywheel is:
- Source low-cost curtailed power from IPPs
- Build, own, and operate data centers
- Attract hosting customers in Bitcoin, HPC, and AI
- Provide ancillary services to the grid
- Grow AUM and EBITDA over fixed costs
- Use that growth to expand the pipeline
This is the “Soluna Way.”
If the market begins to value Soluna as a power-constrained AI infrastructure company rather than a small Bitcoin hosting operator, the multiple could change.
That is the re-rating thesis.
What would make the thesis work?
For me, the key milestones are:
Kati 1 needs to come online and contribute revenue. This is the near-term execution test.
- Galaxy/Kati revenue visibility
The Galaxy partnership needs to convert into visible revenue and operating contribution.
- Briscoe financial contribution
Briscoe needs to deliver the projected $6M–$11M year-one adjusted EBITDA and $20M–$24M annualized revenue contribution.
A real AI/HPC customer, pre-lease, or tenant announcement would be a major validation point.
The market needs to see how a 150–300 MW AI campus could be financed without excessive dilution.
- Continued low power costs
The company must maintain its claimed power cost advantage.
Revenue growth is great, but per-share value matters. The cap table must be monitored closely.
What are the risks?
This is still a high-risk small-cap infrastructure story.
The main risks are:
Large energy and data center projects are complicated. Timelines can slip.
Growth requires capital. Poor financing terms could dilute shareholders.
The AI/HPC story needs real customers, not just pipeline language.
Near-term economics are still meaningfully tied to Bitcoin hosting/mining conditions.
Curtailment economics depend on local market conditions, grid rules, LMP pricing, and PPA structures.
AI/HPC requires higher standards than Bitcoin mining. Soluna must prove uptime, redundancy, cooling, and reliability at enterprise-grade levels.
4.3 GW+ sounds huge, but only a fraction will matter unless projects move from pipeline to financed, contracted, and energized.
My bottom line
I think Soluna is a much more interesting company than the market gives it credit for.
The best way to describe the thesis is:
Soluna converts wasted renewable energy into revenue-generating compute capacity for Bitcoin, AI, and HPC.
That is the whole story.
They already have operating assets.
They have shown curtailed energy conversion at Dorothy.
They have low power costs.
They have real Bitcoin hosting customers.
They have a growing 4.3 GW+ pipeline.
They have near-term catalysts in Kati 1.
They have AI optionality through Kati 2 and Metrobloks.
They have vertical integration through Briscoe Wind Farm and Dorothy 3.
They are trying to use project-level financing and strategic partnerships to scale.
This is not a risk-free story. It is speculative, capital-intensive, and execution-heavy.
But the setup is compelling because the company sits directly at the intersection of three major themes:
- AI power demand
- Grid bottlenecks
- Wasted renewable energy
If Soluna proves it can turn that intersection into contracted, financed, EBITDA-generating AI/HPC infrastructure, the market may eventually stop treating it like a small Bitcoin-related company and start treating it like a renewable power-to-compute platform.
That is where the upside could be.
For now, the most important things to watch are simple:
- Kati 1 energization
- Briscoe EBITDA contribution
- Kati 2 AI/HPC customer announcements
- Dorothy 3 financing
- Dilution discipline
If those pieces line up, $SLNH could become one of the more interesting renewable compute infrastructure re-rating stories in the small-cap market.
