Unitil Energy Systems (NH)

Unitil Energy Systems (NH) serves New Hampshire with a residential electricity rate of $0.24 per kWh. This is 43% above the national average of $0.168/kWh, meaning solar savings are especially significant for customers looking to reduce their energy costs.

At current rates, a typical Unitil Energy Systems (NH) household using 900 kWh per month spends approximately $2,592 per year on electricity. An 8 kW solar system can offset most or all of that usage, saving an estimated $2,304 annually and $84,002 over the 25-year life of the system. The estimated payback period is 10.8 years.

Unitil Energy Systems (NH) offers net metering for solar customers, with credits applied as retail. Heat pump rebates of up to $2,500 are available. Third-party ownership through solar leases and power purchase agreements (PPAs) is available, which can qualify for the 30% commercial Investment Tax Credit under Section 48.

The federal residential solar tax credit (Section 25D) expired at the end of 2025. State and utility-level incentives are now the primary financial benefits for homeowners going solar. NuWatt Energy handles the entire process from system design through permits and Unitil Energy Systems (NH) interconnection, ensuring you receive every available rebate.
