Accelerating Economic and Environmental Sustainability

Portsmouth Community Power expands energy choices for our City's residents and businesses, while lowering costs.

In 2023, the Portsmouth City Council adopted the Portsmouth Community Power Plan.

We are now putting that plan into action to create short- and long-term benefits for the people of Portsmouth.


How Community Power Works

Portsmouth Community Power combines the buying power of residents and businesses so that together we can achieve competitively priced electricity. Customers are always free to choose to buy power from Eversource, or from another supplier, by submitting notice in advance of their next utility meter read date.

As part of the Community Power Coalition of New Hampshire, we can control price volatility and choose which energy sources to buy or build.


Portsmouth Community Power purchases electricity from the sources you choose.


Eversource delivers the electricity using the same power line infrastructure and billing mechanisms.


Portsmouth Energy Customers save money and have the power to choose new rates and products, and how much electricity comes from renewable sources.

Electricity markets are changing. Customers are generating their own power and adopting new technologies that add value to our energy portfolio.

Portsmouth Community Power will harness that value, and empower customers to create a more innovative and cost-effective energy future.

For example, you would be charged the Community Power rate shown for “July” for usage during the period between when Eversource reads your meter in July until the utility closes your billing cycle by reading your meter again about one month later. (Refer to our FAQs for more details.)

Community Representation

Portsmouth joined dozens of other New Hampshire cities and towns to create our own locally accountable nonprofit power agency — Community Power Coalition of New Hampshire.

The City of Portsmouth appoints representatives to the Coalition to oversee the agency's governance and finances. Meet our Member Representatives!

The Coalition


In August, 2021, the City Council created the Blue Ribbon Energy Advisory Committee to "research the risks and opportunities of Community Power." The committee concluded Community power would offer lower rates than Eversource default and be an effective way to decarbonize our local electricity consumption through the best renewable energy options. In July, 2022, Portsmouth chose CPCNH to be our energy supplier and joined the Coalition. The Energy Advisory Committee guided the creation of Portsmouth Community Power and CPCNH implements it on our resident's behalf. Portsmouth has a voice and a vote in CPCNH through our board representation.
