The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Date Effective:
Expiration Date:
H.B. 7727

Note: As of June 2014, H.B. 7727 eliminated the reserved net metering requirement for 2 MW for projects less than 50 kW and removed aggregate capacity limit of 3% of peak load for all utilities except for Block Island Power Company and Pascoag Utility District.


Rhode Island allows net metering for systems up to five megawatts (MW) in capacity that are designed to generate up to 100% of the electricity that a home or other facility uses. Systems that generate electricity using solar energy, wind energy, ocean-thermal energy, geothermal energy, small hydropower, biogas from anaerobic digestion, or fuel cells using any of these energy sources are eligible. All customers of electric distribution companies are eligible. The aggregate amount of net-metered systems in Block Island Power Company and Pascoag Utility District is capped at 3% of the peak load for each utility district.

Net Excess Generation:

The rate credited for kilowatt-hours (kWh) generated that do not exceed the customer's kWh consumption for that billing period is equal to the utility's retail rate (minus a very small conservation charge per kWh). Any excess kWh that do not exceed 125% of the customer's kWh consumption for that billing period are credited at the utility's avoided cost rate. Excess credit may be carried forward to the next bill or purchased by the utility (at its discretion). To facilitate the administration of billing, utilities may estimate a net-metered customer's generation and consumption over a 12-month period. Otherwise, the rates (including customer charges and demand charges) that apply to a net-metered customer must be the same rates that would apply if the same customer were not net metering. Utilities may not impose any other charges on net-metered customers. Net-metered customers are exempt from back-up or standby rates commensurate with the size of the net-metered system. Utilities my recover through rates any revenue shortfall caused by this exemption.

Meter Aggregation:

A system generally must be owned by the customer of record and sited on the customer's premises (in the same geographic location). However, facilities (1) owned by public entity* or multi-municipal collaborative or (2) owned and operated by a developer on behalf of public entity or multi-municipal collaborative through “public entity net metering financing arrangement”** are also eligible. Meter aggregation is generally allowed, and special provisions exist to accommodate meter aggregation for farm-based systems that serve facilities in close proximity to each other.

*A  "public entity" is defined as the municipalities, wastewater treatment facilities, public transit agencies or any water distributing plant or system.

**A "public entity net metering financing arrangement" is defined as an arrangement between a public entity or multi-municipal collaborative and a private entity to facilitate the financing and operation of a net-metered system. Such systems are owned and operated by the private entity and must be located on property owned or controlled by the public entity or one of the municipalities.
