However, the average monthly electricity bill in New Hampshire is below the national average because electricity consumption is considerably less than the national average. New Hampshire ranks 45th in residential, 50th in commercial and 44th in industrial electricity consumption.
Electricity rates are seasonal and volatile in New Hampshire. In November 2014, some companies nearly doubled their rates. A combination of low winter temperatures, high demand for natural gas and limited natural gas pipeline infrastructure led to volatile electricity rates. In contrast, Vermont's reliance on hydropower makes electricity rates less vulnerable to changes in natural gas pricing.
