Soluna and Siemens Partner to Address GPU Power Swings in Behind-the-Meter AI

Soluna Holdings, Inc. (“Soluna” or the “Company”), a developer of green data centers for intensive computing applications, including Bitcoin mining and AI, signed a Memorandum of Understanding (MOU) with Siemens, a leading technology company in electrification, automation and digitalization. The project will deploy and validate a behind-the-meter power-and-controls approach to manage rapid, GPU-driven swings in power demand when running AI and high-performance computing workloads directly on renewable energy.

The 2 MW pilot, expected to be deployed at Soluna’s Project Grace site in Texas, will integrate Siemens’ electrical infrastructure, controls, and monitoring through a structured commissioning process to document performance under fast load steps and variable compute demand, creating a repeatable blueprint for future behind-the-meter AI deployments at renewable generation sites.

AI demand is accelerating, but GPU-driven workloads can create rapid swings in power demand that challenge stability and power quality in behind-the-meter environments powered by renewables. At the Project Grace site, Soluna and Siemens will use the pilot to capture performance data and operational learnings under representative workloads. These findings are expected to inform how the approach can be replicated across future behind-the-meter 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.”

Project Grace will be fully 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 utilize the Siemens SICAM SCADA platform for monitoring and control.

“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.”

Looking ahead, Soluna and Siemens anticipate validating an enterprise-grade, repeatable blueprint for behind-the-meter renewable compute, combining Siemens’ proven power infrastructure and controls with Soluna’s renewable-first data center model. Together, we aim to innovate to ensure customers will scale AI and high-performance workloads faster – with measurable gains in grid stability, energy efficiency, and carbon impact.
