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.

A quarterback reportedly reneging on a lucrative deal to hit the transfer portal, only to return to his original school. Another starting QB, this one in the College Football Playoff, awaiting approval from the NCAA to play next season, an expensive NIL deal apparently hanging in the balance. A defensive star, sued by his former school after transferring, filing a lawsuit of his own.

It is easy to see why many observers say things are a mess in college football even amid a highly compelling postseason.

“It gets crazier and crazier. It really, really does,” said Sam Ehrlich, a Boise State legal studies professor who tracks litigation against the NCAA. He said he might have to add a new section for litigation against the NCAA stemming just from transfer portal issues.

“I think a guy signing a contract and then immediately deciding he wants to go to another school, that’s a kind of a new thing,” he said. “Not new kind of historically when you think about all the contract jumping that was going on in the ’60s and ’70s with the NBA. But it’s a new thing for college sports, that’s for sure.”

Washington quarterback Demond Williams Jr. said late Thursday he will return to school for the 2026 season rather than enter the transfer portal, avoiding a potentially messy dispute amid reports the Huskers were prepared to pursue legal options to enforce Williams’ name, image and likeness contract.

Edge rusher Damon Wilson is looking to transfer after one season at Missouri, having been sued for damages by Georgia over his decision to leave the Bulldogs. He has countersued.

Then there is Ole Miss quarterback Trinidad Chambliss, who reportedly has a new NIL deal signed but is awaiting an NCAA waiver allowing him to play another season as he and the Rebels played Thursday night's Collge Football Playoff semifinal against Miami. On the Hurricanes roster: Defensive back Xavier Lucas, whose transfer from Wisconsin led to a lawsuit against the Hurricanes last year with the Badgers claiming he was improperly lured by NIL money. Lucas has played all season for Miami. The case is pending.

Court rulings have favored athletes of late, winning them not just millions in compensation but the ability to play immediately after transferring rather than have to sit out a year as once was the case. They can also discuss specific NIL compensation with schools and boosters before enrolling and current court battles include players seeking to play longer without lower-college seasons counting against their eligibility and ability to land NIL money while doing it.

Ehrlich compared the situation to the labor upheaval professional leagues went through before finally settling on collective bargaining, which has been looked at as a potential solution by some in college sports over the past year. Athletes.org, a players association for college athletes, recently offered a 38-page proposal of what a labor deal could look like.

“I think NCAA is concerned, and rightfully so, that anything they try to do to tamp down this on their end is going to get shut down,” Ehrlich said. “Which is why really the only two solutions at this point are an act of Congress, which feels like an act of God at this point, or potentially collective bargaining, which has its own major, major challenges and roadblocks.”

The NCAA has been lobbying for years for limited antitrust protection to keep some kind of control over the new landscape — and to avoid more crippling lawsuits — but bills have gone nowhere in Congress.

Collective bargaining is complicated and universities have long balked at the idea that their athletes are employees in some way. Schools would become responsible for paying wages, benefits, and workers’ compensation. And while private institutions fall under the National Labor Relations Board, public universities must follow labor laws that vary from state to state; virtually every state in the South has “right to work” laws that present challenges for unions.

Ehrlich noted the short careers for college athletes and wondered whether a union for collective bargaining is even possible.

To sports attorney Mit Winter, employment contracts may be the simplest solution.

“This isn’t something that’s novel to college sports,” said Winter, a former college basketball player who is now a sports attorney with Kennyhertz Perry. “Employment contracts are a huge part of college sports, it’s just novel for the athletes.”

Employment contracts for players could be written like those for coaches, he suggested, which would offer buyouts and prevent players from using the portal as a revolving door.

“The contracts that schools are entering into with athletes now, they can be enforced, but they cannot keep an athlete out of school because they’re not signing employment contracts where the school is getting the right to have the athlete play football for their school or basketball or whatever sport it is,” Winter said. “They’re just acquiring the right to be able to use the athlete’s NIL rights in various ways. So, a NIL agreement is not going to stop an athlete from transferring or going to play whatever sport it is that he or she plays at another school.”

There are challenges here, too, of course: Should all college athletes be treated as employees or just those in revenue-producing sports? Can all injured athletes seek workers' compensation and insurance protection? Could states start taxing athlete NIL earnings?

Winter noted a pending federal case against the NCAA could allow for athletes to be treated as employees more than they currently are.

“What’s going on in college athletics now is trying to create this new novel system where the athletes are basically treated like employees, look like employees, but we don’t want to call them employees,” Winter said. “We want to call them something else and say they’re not being paid for athletic services. They’re being paid for use of their NIL. So, then it creates new legal issues that have to be hashed out and addressed, which results in a bumpy and chaotic system when you’re trying to kind of create it from scratch.”

He said employment contracts would allow for uniform rules, including how many schools an athlete can go to or if the athlete can go to another school when the deal is up. That could also lead to the need for collective bargaining.

“If the goal is to keep someone at a school for a certain defined period of time, it’s got to be employment contracts,” Winter said.
