New Hampshire’s Renewable Portfolio Standard (RPS) is intended to increase use of renewable resources in the state by establishing the minimum amount of renewable energy that the state’s electricity providers must sell in a given year. This legally-established renewable energy procurement goal gradually increases over time to meet the overall target of 24.8% renewable power by 2025.

The state profile below explores the design of this policy, highlighting the factors that influence the success of New Hampshire’s RPS goals and the tradeoffs inherent to it. Once you’re comfortable with the information on this page, you can evaluate the policy’s expected viability with the RPS Feasibility Calculator. You can also use the calculator to change the policy requirements, trajectory, cost cap, and more, to see how altering New Hampshire’s policy design affects its success.

RPS Snapshot


  • 24.8% of the state’s energy consumption must be from renewable sources by 2025, subject to the cost cap
  • Carve-out for solar
  • Implicit ‘cost cap’ defined by compliance payments


Carve-outs can create economic opportunities in the state by introducing new or promising technologies into the market. However, these standards limit the utilities’ ability to substitute between renewable energy sources, potentially increasing the cost of the policy. New Hampshire requires that, beginning in 2010, 0.04% of the annual RPS requirement be met through new solar sources. The carve-out ramps up to 0.3% of the annual requirement in 2014 and thereafter.

Cost Cap Details

New Hampshire does not have an explicit cost cap. However, by allowing alternative compliance payments (ACPs), New Hampshire sets an effective cap on the premium a utility will be willing to pay for renewable energy. The RPS sets this cap at $55/MWh for Class I (see Legislation section for more details). Like some states, New Hampshire adjusts the cost of an ACP over time according to inflation. If the renewable energy premium exceeds this cap, the utility would prefer to meet the standard by making the lower cost alternative compliance payments.

Historic retail prices (¢ / kWh)

The above chart presents historical data from the Energy Information Administration (EIA) on the price at which residential customers can purchase electricity. Typically, states set explicit cost caps relative to the retail price (as opposed to the lower wholesale price).



New Hampshire’s Electric Renewable Portfolio Standard requires that all electricity providers—excluding municipalities—deliver 24.8% renewable energy by 2025. The requirements are broken up into four Classes, each with specific technologies and individual compliance schedules, and alternative compliance payments. Class I comprises the majority of the RPS at 15% of the annual requirement by 2025. Falling within Class I, 2.6% must come from ‘useful thermal energy’ by 2025. The other three Classes are as follows: 0.3% of the annual requirement must be from Class II (new solar) by 2014; 8% from Class III (exiting biomass) by 2015; and 1.5% from Class IV (existing hydro) by 2015.
