R.I. Gen. Laws § 39-26.6-18
Owners of medium-scale, commercial-scale, and large-scale solar projects and other distributed-generation technologies shall be required to provide, at their cost, a revenue-quality meter to standards approved by the division of public utilities and carriers and provide access to the information from the meter to the electric distribution company to measure the output of the generation. The electric distribution company shall have the discretion to install the second meter in a parallel configuration to the retail meter or behind the meter, provided that a parallel installation shall have no effect on the right of the customer to net meter using the net of the two meters. The electric distribution company also shall have the right to install its own revenue-quality meter for small-scale solar projects if not being supplied by the owner. The electric distribution company shall recover the installation and capital cost of the separate meters it installs for small-scale solar projects in the annual reconciliation of solar costs under § 39-26.6-25.
