After 40 years in operation, the Vermont Yankee Nuclear Power Station in Vernon shuttered in 2014, leaving over 100,000 tons of nuclear waste. More than a decade later, the developer that holds the lease, PowerTransitions, is in the midst of envisioning the site’s future. 

Now, the local community and state are mulling the potential energy, environmental and economic impacts of the site redevelopment, which could include a data center. 

After purchasing the 140 acre property, NorthStar, which specializes in facility remediation, is on track to decommission the nuclear site by the end of the year, according to Kerrick Johnson, the Vermont Department of Public Serviceโ€™s commissioner.

NorthStar agreed to lease the property to Texas-based company PowerTransitions, which is  backed by private equity firm Partners Group. It specializes in converting former industrial areas into energy development sites with a focus on solutions to the growing AI and digital infrastructure demand.

It is unclear what PowerTransitions will build. 

Jim Pinkerton, a Vernon Select Board member who also chairs the townโ€™s planning commission, reported at a Tuesday night selectboard meeting that plans for battery storage, a small-scale nuclear reactor and a data center had all been floated by PowerTransitions, but no plan had been finalized. 

โ€œAny of the projects they’re discussing would trigger (Act) 250 instantly,โ€ Pinkerton said, referring to Vermontโ€™s land use review process. The process typically takes many months or years to navigate, Pinkerton said, adding that โ€œthere will be two years before they even get a ruling on it.โ€

PowerTransitions is in the early stage of developing plans for the site, and the company intends on engaging with the Vernon community and other stakeholders, according to a statement by PowerTransitions spokesperson Carrie Hitt. PowerTransitions currently plans to build a data center in Kansas.

Last month, Gov. Phil Scott vetoed a bill that would have placed restrictions on data centers, asserting that the stateโ€™s existing regulatory frameworks would suffice in limiting any negative impacts. Scott has also long supported the revival of nuclear energy in the state.

Data center developments have caused a stir nationally, and Vermont municipalities like South Burlington and Royalton have weighed data center restrictions. Vergennes is contending with current controversy over a proposed battery storage project. 

Pinkerton said that Vernonโ€™s planning commission sees developing an โ€œenvironmentally soundโ€ project that generates revenue as a โ€œregional gain.โ€ But he said the town would need to weigh the downsides as well. 

Pinkerton also expressed personal concern about redeveloping a nuclear site and the potential โ€œserious drainโ€ on local water and power resources of a data center. This concern was echoed by some attendees at the selectboard meeting Tuesday. 

In cleaning up the Vermont Yankee facility, NorthStar shipped low radiation waste to Texas and contained high radiation waste in 59 casks on site, Johnson, the public service department commissioner, said in an interview. These will remain under supervision by the Federal Nuclear Regulatory Commission, he said. 

The department wants the site to generate the greatest value, Johnson said, and different uses of the site โ€œcheck different boxes.โ€

Battery storage has advantages, said Johnson, but development would be costly and time intensive, while potentially under utilizing the energy transmission capacity of the site.

While there is interest in nuclear development, Johnson said, Vermont has significant and unique regulatory requirements for a company seeking to construct a small modular reactor. 

Any data center development would need to generate its own energy so that it would not tax the power grid, Johnson said, and a disadvantage of a data center plan is that the public perception is โ€œpretty negative.โ€

โ€œWe’re looking more for something that puts energy out, not necessarily something that needs more energy,โ€ Johnson said. 

NorthStarโ€™s CEO Scott State said in a statement that his company intended to connect potential developers with the Vernon community and that his company did so with PowerTransitions.

Johnson said his department and PowerTransitions are in talks to reach an agreement outlining expectations for community engagement and environmental impacts.

The loss of Vermont Yankee has had repercussions on the stateโ€™s energy capacity, Johnson noted. โ€œFollowing the exit of that key employer in that region, we have energy affordability needs, we have energy adequacy needs, meaning we need more sources of clean energy,โ€ he said. โ€œWe’re in the process of developing options, and hopefully one of those options will come to fruition that best benefits the community, the state and the region.โ€
