New Hampshire’s Electric Utility Restructuring Law unbundled generation and opened the retail market to competition. Businesses can select a third-party supplier instead of taking basic service from the utility, which can result in lower per-kilowatt-hour costs and the ability to lock in long-term contracts. The state’s investor-owned utilities include Eversource New Hampshire, Unitil, Liberty Utilities and the New Hampshire Electric Cooperative. These utilities continue to deliver power and handle outages, while competitive energy suppliers provide the generation portion of your bill.
Natural Gas Market in New Hampshire
In parts of New Hampshire where pipeline gas is available, businesses may also be able to choose their natural gas supplier. Unitil’s Northern Utilities division and Liberty Utilities deliver gas to customers in towns like Portsmouth, Concord and greater Manchester. Licensed natural gas marketers offer supply contracts with fixed per-therm pricing, giving commercial customers an opportunity to budget fuel costs and avoid seasonal price volatility.
