Soluna Holdings, Inc., a developer of green data centers for intensive computing applications, has signed a Memorandum of Understanding (MOU) with Siemens, a technology company, to deploy and validate a power and controls approach for managing rapid, GPU-driven power demand swings from AI and high-performance computing workloads directly on renewable energy.
The 2 MW pilot project is planned for Soluna’s Project Grace site in Texas. It will integrate Siemens’ electrical infrastructure, controls, and monitoring through a structured commissioning process to document performance under fast load steps and variable compute demand. This initiative aims to create a repeatable blueprint for future behind-the-meter AI deployments at renewable generation sites.
AI demand is growing rapidly, but GPU-driven workloads can create swift fluctuations in power demand. These fluctuations challenge stability and power quality in behind-the-meter environments powered by renewables. The pilot at Project Grace will capture performance data and operational learnings under representative workloads, informing how this approach can be replicated across future deployments at renewable generation sites.
John Belizaire, CEO of Soluna, stated, “One of the biggest challenges to scaling AI technology is the amount of compute power it demands. 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.”
Project Grace will be equipped with Siemens electrical and mechanical equipment, including transformers, switchgear, power converters, and ancillary systems. The pilot will test this equipment in a behind-the-meter environment and establish performance metrics to ensure scalability, grid stability, and energy efficiency. The facility will use the Siemens SICAM SCADA platform for monitoring and control.
Brian Dula, President of Electrification and Automation at Siemens Smart Infrastructure USA, commented, “We believe AI has become foundational to every industry, and we’re focused on removing today’s roadblocks so the technology can scale responsibly. 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.”
Looking ahead, Soluna and Siemens anticipate validating an enterprise-grade, repeatable blueprint for behind-the-meter renewable compute. This blueprint will combine Siemens’ power infrastructure and controls with Soluna’s renewable-first data center model, aiming to help customers scale AI and high-performance workloads faster with measurable gains in grid stability, energy efficiency, and carbon impact.
