ALBANY, NY, Jan 12, 2026 – Soluna Holdings (Soluna) signed a memorandum of understanding (MoU) with Siemens to deploy and validate a behind-the-meter power and controls approach. The project will manage GPU-driven power swings from AI and high-performance computing workloads running on renewable energy.
Soluna plans to deploy a 2 MW pilot at Project Grace site in TX. The project will integrate Siemens’ electrical infrastructure, controls, and monitoring through a commissioning process. It will document performance under rapid load changes and variable compute demand to support repeatable behind-the-meter AI deployments at renewable generation sites.
GPU-based AI workloads can cause rapid power swings in behind-the-meter renewable systems. Soluna and Siemens will use the Project Grace pilot to collect performance data and operational learnings under representative workloads. The results will inform future deployments at renewable generation sites.
“One of the biggest challenges to scaling AI technology is the amount of compute power it demands,” said John Belizaire, CEO of Soluna. “The value of this partnership is the opportunity to solve that challenge with infrastructure that already exists. We can tap into clean energy that would otherwise go unused, at a competitive cost to grid power, to create a win-win for power providers and customers.”
Soluna will equip Project Grace with Siemens transformers, switchgear, power converters, and ancillary systems. The pilot will evaluate performance in a behind-the-meter environment and establish performance metrics to ensure scalability, grid stability, and energy efficiency. Monitoring and control will run on the Siemens SICAM SCADA platform.
“We believe AI has become foundational to every industry, and we’re focused on removing today’s roadblocks so the technology can scale responsibly,” said Brian Dula, president of electrification and automation at Siemens Smart Infrastructure USA. “This pilot with Soluna allows us to test, validate, and demonstrate what’s possible when renewable energy and existing infrastructure are optimized to power AI, both today and in the future.”
Soluna and Siemens plan to validate a repeatable model for behind-the-meter renewable compute. The approach combines Siemens power infrastructure and controls with Soluna’s renewable-first data center design to support AI and high-performance workloads, while measuring impacts on grid stability, energy efficiency, and carbon performance.
