Tracking system: New England Power Pool Generation Information System (NEPOOL-GIS)
Rhode Island extended its renewable energy standard from 2019 to 2035 in 2016. It requires investor-owned utilities (IOUs) and retail suppliers to procure a certain percentage of their electricity from renewable energy.
In 2016, a bill was passed that included provisions of several solar policies, including establishment of community virtual net metering, increasing the system size limit for net metering, and property tax exemption for solar systems. Its net metering program accommodates medium to large sized customers. However, net excess generation is credited at the utility's avoided cost rate instead of the retail rate.
In 2016, Rhode Island increased the net metering system capacity limited from 5 MW to 10 MW and established community virtual net metering. IOUs must offer net metering to their retail customers. IOUs cannot increase demand charges and customer chargers above the rate for other customers and cannot impose any other charges on net-metered customers.
System size limit: 10 MW
Aggregate cap: 3% of peak load for Block Island Power Company and Pascoag Utility District; none for National Grid
Credit: Net excess generation credited at utility's avoided cost rate.
RECs: Not addressed
Meter aggregation: Community virtual net metering is allowed. At least 50% of the capacity for the system should be distributed among users ≤25kW.
Applicable to the state's IOU electric distribution companies, Rhode Island's interconnection policy for customer-sited systems require customers to submit application for system-impact studies to the utility. The cost of the impact study fee ranges from $500 to $10,000 for midsized systems.
|Eligible Systems||Type of Interconnection|
|Residential systems ≤25 kW||No impact study fee|
|Residential systems >25 kW||$100 impact study fee|
|Nonresidential systems ≤100 kW||$500 impact study fee|
|Nonresidential systems 100 kW to 1 MWs||$1500 to $10,000 impact study fee|
System size limit: 5 MW
Liability insurance: Not addressed
External disconnect switch: Not addressed
Third Party Ownership
Rhode Island established community virtual net metering in 2016, caping the total amount at 30 MW. The net-metered systems can be owned by one of the participants or by a third-party through a lease or PPA model.
