Electric Renewable Portfolio Standard (RPS)

New Hampshire 's RPS statute, RSA 362-F, requires each electricity provider to meet customer load by purchasing or acquiring certificates representing generation from renewable energy based on total megawatt-hours supplied. New Hampshire ’s RPS statute divides renewable energy sources into four separate classes that include the following:

  • Class I resources include generation facilities that began operation after January 1, 2006 and produce electricity from: wind energy; geothermal energy; hydrogen derived from biomass fuel or methane gas; ocean thermal, wave, current, or tidal energy; methane gas; or biomass. Displacement of electricity by end-use customers from solar hot water heating systems, incremental new production from Class III and IV sources, and existing hydropower and biomass facilities that began operation as a new facility through capital investment also qualify as class I sources.

  • Class II sources include generation facilities that produce electricity from solar technologies and began operation after January 1, 2006 .

  • Class III sources include generation facilities that began operation on or before January 1, 2006 and produce electricity from eligible biomass technologies having a gross nameplate capacity of 25 megawatts or less or methane gas facilities.

  • Class IV: SB 218, enacted in June 2012 modified the definition of a Class IV source.  Class IV sources are now defined as:  hydroelectric generation facilities that began operation on or before January 1, 2006, and when required, have documented applicable state water quality certification under section 401 of the Clean Water Act, and either A) has a capacity of 5 megawatts or less and has actually installed upstream and downstream diadromous fish ladders, or B) has a capacity of one megawatt or less , is in compliance with applicable FERC fish passage restoration requirements, and is interconnected with an electric distribution system located in New Hampshire. Please note that the Commission has issued an Order waiving the PUC’s administrative rule requiring certain Class IV facilities to have installed upstream and downstream diadromous fish passages.  See Order 25,394.

The RPS requirement increases to 7.5% for 2010, 15.8% for 2015 and 24.8% for 2025. The RPS obligations by class and year are:

Obligations highlighted in red indicate changes made with SB148 and HB542.

*Class I thermal is a subset of Class I. The thermal requirements are subsumed in the Class I requirement and are not additional to Class I.

Note that with Order No. 25,484 under Docket No. DE 13-021, the Commission changed the Class III obligations in 2012 and 2013 and the Class I and Class I thermal obligations in 2013.

Pursuant to RSA 362-F:6, II-a, the Commission has computed a final estimate of the percentage credit for Class I and Class II based on the capacity of the customer-sited sources that are net metered and are not certified to create Class I or II renewable energy certificates (RECs). 

Credit for Class I:


Credit for Class II:


This credit is based on the following assumptions:

Total Estimated 2013 Electricity Sales

10,825,482,566  kWh

Customer Sited Sources that are Net Metered and Not Certified to Create RECs


Class I Capacity

392 kW

Class II Capacity

5648 kW

Capacity Factor


At the time of the renewable portfolio standard compliance filing for calendar year 2013, an electricity provider may claim a Class I REC credit equal to the percentage credit for Class I multiplied by the total electricity (mWh) provided to end-use customers by that electricity provider. In addition, an electricity provider may claim a Class II REC credit equal to the percentage credit for Class II multiplied by the total electricity (mWh) provided to end-use customers.  

Under the RPS statute, electricity providers are required to generate or purchase renewable energy certificates from suppliers through the New England Power Pool generation information system (NEPOOL-GIS). A renewable energy certificate represents 1 megawatt-hour of electricity produced from eligible renewable energy sources and may be sold separately from the associated electricity.

If the electricity providers are not able to meet the RPS requirements by purchasing or acquiring renewable energy certificates, they must pay alternative compliance payments (ACPs). The 2012 alternative compliance payment prices by class are:

Inflation Adjusted Alternative Compliance Payment per Megawatt Hour

  2008 2009 2010 2011 2012 2013 2014
Class I  $   58.58  $   60.92  $   60.93  $   62.13  $  64.02  $ 55.00  $ 55.37
Class I thermal            $ 25.00  $ 25.17
Class II  $ 153.85  $ 159.98  $ 160.01  $ 163.16  $ 168.13  $ 55.00  $ 55.37
Class III  $   28.72  $   29.86  $   29.87  $   30.46  $   31.39  $ 31.50  $ 31.93
Class IV  $   28.72  $   29.86  $   29.87  $   30.46  $   31.39  $ 26.50  $ 26.86

Proceeds from the ACPs are then used to fund qualified renewable energy initiatives and projects.

On an annual basis, the New Hampshire Public Utilities Commission will review electricity providers’ compliance with the previous year’s RPS requirements. Electricity providers include New Hampshire ’s competitive electricity suppliers and electric distribution utilities (Public Service Company of New Hampshire, Granite State Electric Company, Unitil Energy Systems, Inc. and the New Hampshire Electric Cooperative).  In accordance with the Commission administration rules, Chapter Puc 2500 which implements the New Hampshire ’s RPS Program, electricity providers file annual compliance reports by July 1 st of each year.
