With these funds, Soluna will commence Project Kati 1 construction in Q3 2025, with the goal of achieving initial energization and ramp-up by Q1 2026.

“Spring Lane Capital has walked alongside Soluna on our path to growth since the beginning with an investment in Project Dorothy,” said John Belizaire, CEO of Soluna. “We expect these funds to fuel the construction of the first 35MW of the 83MW phase of Kati 1, which expands Soluna’s Texas fleet for Bitcoin Hosting.”

Key details

• Financial Structure and Equity Ownership: Soluna expects that the $20 million will fully cover the project’s funding needs, including working capital. Kati 1 continues the superior waterfall structure and enhanced management and development fees, allowing Soluna to benefit from substantial current income during the construction and operational phases.
• Construction Timeline: The parties intend to commence Project Kati 1 construction in Q3 2025, with the goal of achieving initial energization and ramp-up by Q1 2026.
• Capacity and Technology: The new facility is designed to accommodate approximately 12,000 next-generation Bitcoin mining rigs.
• SLC’s Expanded Financial Support: SLC and Soluna previously signed an agreement to extend up to $100M of additional project-level capital for Soluna’s growing data center pipeline for Bitcoin and AI, subject to certain conditions precedent.
• Fund 2 Investment: SLC deployed its capital from its second private equity fund, Spring Lane Capital Fund II, which is twice the size of its initial fund. The fund is lined up to provide up to $4 million in Development Expenditure (DevEx) financing for Soluna’s long-lead equipment purchases.
• Project Approvals: Kati 1 already has all the necessary ERCOT planning approvals. An ERCOT model update will be submitted at least 90 days before energization.

“We continue to invest in and be strategic supporters of Soluna because they continue to take steps toward sustainable high-performance computing and meeting green data center demand,” said Rob Day at Spring Lane Capital. “We’re looking forward to construction getting underway at Project Kati so that Soluna can continue expanding its green computing power.”
