Electricity

 

New Hampshire allows customers of Public Service of New Hampshire (PSNH), Unitil, Granite State Electric Company (GSEC), and the New Hampshire Electric Cooperative (NHEC) to choose their electric supply provider. The New Hampshire utilities sold most of their power plants to open the market to competition, though PSNH still owns some generation. Utilities still own the transmission and distribution wires. Customers who do not choose an alternate energy provider receive default service from the utility. Utilities buy default service supplies throughout the year on the wholesale market, with PSNH using its own generation for some of the supplies. For most customers, default service rates change every six months. For large business customers, Granite State Electric default service rates change monthly.

 

Natural Gas

 

New Hampshire allows all customers to choose a different company to supply them with their gas supply. Gas supply is still delivered by the local utility. Customers that do not opt for an alternate gas supplier receive default supply service from their utility called “cost of gas” which can vary as often as monthly.
