NH House Rejects Advanced Nuclear Bill After Utility Monopoly Fears Erupt
New Hampshire House lawmakers rejected a bill that would have let utilities own advanced nuclear reactors, dealing a setback to one of the state’s most closely watched energy proposals.
The vote matters beyond Concord because supporters framed it as groundwork for future power reliability, while critics warned it could reopen monopoly-style utility control.
According to New Hampshire Bulletin, Senate Bill 447 would have allowed utilities to build and own advanced reactors up to 300 megawatts. The measure had already passed the Senate before failing in the House.
That rejection exposed a deeper divide.
Backers argued advanced nuclear could strengthen energy security as demand rises. Opponents warned utility ownership could shift risks to ratepayers and distort electricity competition.

“This compromises the goal of energy diversification,” Rep. Chris Muns said during debate.
The fight also raised bigger questions about small modular reactors, an industry still largely emerging but increasingly pushed as part of future energy planning.
For supporters, the defeat could slow momentum for New Hampshire to position itself in advanced nuclear development.
For critics, it blocked what they viewed as a costly policy gamble before the technology is proven at scale.
The vote may not settle the issue.
Lawmakers in recent years have repeatedly revisited proposals tied to utility-owned generation, and energy demand tied to industrial growth and data centers is keeping pressure on policymakers.
With the bill rejected, attention now shifts to whether supporters revive a revised proposal or pursue narrower nuclear legislation in the next session.
For now, the House vote stops this effort, but not the broader nuclear debate.
