Soluna Raises $35M from Spring Lane Capital to Build Green Data Centers for Crypto, Machine Learning

Soluna Holdings, Inc. (“SHI” or the “Company”), (NASDAQ: SLNH), the parent company of Soluna Computing, Inc. (“SCI”), secured $35 million in project financing to develop green data centers co-located with renewable energy assets. Spring Lane Capital, a private equity firm, invested private funds in Soluna as a part of their strategy focused on hybrid project capital for sustainability solutions in the energy, food, water, waste and transportation industries. The capital will help develop three behind-the-meter (BTM) projects designed to convert wasted renewable energy into clean computing services such as bitcoin mining and artificial intelligence.

“Soluna is the only true green bitcoin company we’ve yet seen,” said Rob Day, Spring Lane Capital Partner and Co-Founder. “Going after wasted renewable energy ‘spilled power’ is a compelling solution and fixes both bitcoin’s climate problem and wind power’s grid problem.”

Michael Toporek, CEO of Soluna Holdings, Inc. said, “Consistent with our previously articulated strategy, we continue to pursue opportunities that we believe enable us to optimize our cost of capital. The Spring Lane Capital approach helps us develop a mature repeatable model that can be scaled.”

The first of the three projects, Dorothy, named in honor of African American mathematician and human computer Dorothy Vaughan, is expected to be energized later this summer and coincide with the launch of a local STEM program. The Dorothy project is a 100 MW data center with a 50 MW initial phase, connected to a Texas wind farm that produces more electricity than the grid can consume. Soluna’s data center is currently estimated to create between 25 to 50 highly skilled jobs for technicians, security and electrical staff.

The other two projects funded by the new capital will come from Soluna’s robust pipeline.

John Belizaire, CEO of Soluna Computing, Inc., said, “We are honored to have a pioneering sustainability project finance firm like Spring Lane Capital back our vision. Our model of leveraging excess clean energy to generate low-cost computing is the future of green bitcoin mining and green data centers.”

Spring Lane Capital has a successful track record helping sustainable technology companies raise capital to build flagship projects. Their ‘hybrid project capital’ approach provides project equity along with additional growth capital.

Added Day: “Soluna is driving demand for clean power by giving a floor price and improving the bottom line of the renewable power partners they work with. The ultimate result is more wind farms and solar farms that would not otherwise be built.”

At power plants like the wind farm where the Dorothy project is under construction, excess energy is wasted when the grid becomes overloaded or demand is too low. Soluna’s scalable solution allows every excess megawatt to be used for batch-oriented, computing-intensive processes, such as cryptocurrency mining and machine learning. Additionally, flexible demand consumers help stabilize the grid by preventing power overload, which can otherwise lead to blackouts and grid malfunction.

Last month, Soluna Holdings (SCI’s Computing’s parent company), sold its Albany-based MTI Instruments subsidiary for $10.75 million, expanding its focus on helping the modern grid absorb more renewable energy through flexible green data centers.

Soluna Launches Curtailment Assessment Service for Clean Power Producers

Curtailed Power Costs Renewable Asset Owners up to 30% of their Generating Potential

Soluna Holdings, Inc. (Nasdaq: SLNH) (formerly Mechanical Technology), a developer of green data centers for cryptocurrency mining and other intensive computing, announced today that it is now offering a custom estimating service for clean energy power plant owners and developers looking to reduce costly curtailment problems. The custom Curtailment Assessment is an NDA-protected review of proprietary, project-level data to estimate both lost and recoverable revenue with the addition of flexible offtake of curtailed power by Soluna’s modular data centers (MDC).

“We started as a wind developer, so we know that curtailment can steal up to 30 percent of an asset owner’s power generation/profit potential,” said Soluna Computing CEO John Belizaire. “That’s been accepted as a given. We say it’s now an avoidable cost, and we’re out to show asset owners that they don’t have to watch their margins drain away.”

Curtailment occurs when clean electricity providers, such as solar and wind farms, cannot sell all their power to a congested or over-supplied grid or must sell it at a loss. Curtailment costs power plant owners up to $2 million per year due to a failure to deliver on contracted power purchase agreements (PPAs), the loss of Production Tax Credits (PTC), and Renewable Energy Certificates (RECs).

Soluna’s Curtailment Assessment is a groundbreaking, proprietary service that analyzes a producer’s historical data to determine how much additional revenue owners can see by incorporating flexible energy demand on-site from the company’s modular data centers.

Curtailment Assessment Process
Power partners who are interested in receiving a custom assessment can submit data to Soluna for analysis under NDA. Once received, Soluna’s team analyzes the data, develops the custom Curtailment Assessment and a plan to solve the profit bleed. This plan will include a detailed look at the project’s total output, curtailed energy, seasonality and the financial impact of curtailment.

Soluna’s Curtailment Assessment develops options for boosting revenue, including various sized modular data centers that range from 50 MW to 150MW. The data centers are developed behind the meter to add flexible demand that converts curtailed energy into additional revenue. Soluna can develop and build a modular data center within six months.

“We want to make renewable energy a global superpower, and we will do that by offering our computing centers as an immediately available, cost-effective alternative to battery storage for utility-scale renewable energy plants,” continued John Belizaire.

Having batchable computing capability such as cryptocurrency mining on-site can increase the revenue of a renewable energy project up to 20% to 30%. These on-site scalable data centers consume every excess megawatt that the solar panels or wind turbines aren’t able to sell.
