Strategic Initiatives
Growth programs, investments, and their expected impact
Co-development of a planned multi-phase AI and high-performance computing (HPC) data center campus in Willacy County, Texas, in partnership with Metrobloks. The project is structured in two phases: Phase I (100 MW) and Phase II (250 MW), totaling 350 MW of critical IT capacity.
Expected impact: Establishes a massive, renewable-powered, GPU-ready AI hosting footprint to capture high-density computing demand.
A partnership with Siemens to deploy and validate a 2 MW behind-the-meter power and controls pilot at the Project Grace site in Texas. The pilot is designed to manage rapid, GPU-driven power swings from AI workloads running directly on renewable energy.
Expected impact: Creates a repeatable, enterprise-grade blueprint for behind-the-meter renewable AI deployments, improving grid stability and energy efficiency.
Acquiring the dedicated renewable energy generation assets that power Soluna's data centers to eliminate reliance on third-party power purchase agreements (PPAs) and secure long-term energy certainty.
Expected impact: Achieves full vertical integration for Project Dorothy, creating a durable cost advantage and securing the power foundation required for the Dorothy 3 AI campus expansion.
