R.I. Gen. Laws § 39-26.6-22: Zonal and other incentive payments.

In order to provide the electric distribution company and the board with the flexibility to encourage distributed-generation projects to be located in designated geographical areas within its load zone where there is an identifiable system benefit, reliability benefit, or cost savings to the distribution system in that geographical area, or conservation benefit, or climate resilience benefit in that geographical area, the electric distribution company, the board, or the office, shall propose to include an incentive-payment adder to the bid price of any winning bidder that proposes a distributed-generation project in the preferred sites that require remediation. The company, board, or office can also propose disincentive subtractors for projects outside of preferred sites. The electric distribution company also may propose other incentive payments to achieve other technical or public policy objectives that provide identifiable benefits to customers. Any incentive-payment adders must be approved by the commission, and shall not be counted as part of the bid price when the bids are selected at an enrollment event.
