US Senate Minority Leader Charles E. Schumer, D NY, criticized the bill calling it toothless and said Senate Democrats want to make it mandatory for data centers to cover their own costs by law, not by voluntary agreement
Martin Heinrich has pushed an alternative called the GRID Savings Act that would require large electricity users to pay for the grid infrastructure needed to connect them
The Ratepayer Protection Act would require states to consider adopting standards under which large electricity users including data centers would pay for incremental costs of generation transmission and distribution infrastructure
Sam Hayden, resident of Hopkinton, wrote that construction of hyperscale data center will be detriment to Bow and region because these facilities consume enormous amounts of electricity, provide few permanent jobs, require environmental costs and infrastructure, and risk higher rates
Michael Vose, former chair of the N.H. House Science, Technology, & Energy Committee and sponsor of HB 672, argues that data centers should provide their own power under House Bill 672 rather than being subject to a state moratorium.

Governor Kelly Ayotte stated in response to Bow proposal that she will advocate for towns to decide what is best for them but thinks it is best to institute a moratorium because too many unknowns surround data centers
Shaheen said she would support federal legislation requiring data center developers to pay host communities to cover power and other public assets costs
Cinde Warmington, running in Democratic primary for governor, said on Day One she will issue an executive order placing a temporary moratorium on large scale data centers
Executive Councilor Liot Hill said waiting for a moratorium until the next state budget takes effect in July 2027 is too late and the Governor should use executive authority to put an immediate temporary moratorium in place

Gov. Kelly Ayotte said the head of ISO New England told her that New England can only maybe get one data center of not massive size without jacking up energy prices on people
Gov. Kelly Ayotte stated it does not make sense to site a data center in New Hampshire because the state does not have the energy for it and it is not an appropriate location

The disclosed totals are in the table above.
No source on file states what any of the 3 tracked facilities in New Hampshire are for. 2 sites not yet verified are named apart and are not in that number.
