What was said
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
Senate President Sharon Carson said that the Senate would explore legislation to protect New Hampshire taxpayers from data center development costs.
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.
