2. Financial interest. The program must allow a commercial or institutional customer to participate in the program if the customer has a financial interest in a distributed generation resource, including facility ownership, a lease agreement or a power purchase agreement.
[PL 2019, c. 478, Pt. A, §4 (NEW).]

4. Shared financial interest; limitation. Multiple commercial or institutional customers that have distinct billing accounts with an investor‑owned transmission and distribution utility may share a financial interest in a distributed generation resource under subsection 2.

[PL 2019, c. 478, Pt. A, §4 (NEW).]
5. Tariff rate; bill credits. The commission shall establish by rule tariff rates for customers participating in the program. The initial tariff rate must be established no later than December 1, 2019.
A. The tariff rate for a customer participating in net energy billing with a distributed generation resource described in this paragraph must equal the standard-offer service rate established under section 3212 that is applicable to the customer receiving the credit plus 75% of the effective transmission and distribution rate for the rate class that includes the smallest commercial customers of the investor-owned transmission and distribution utility. The tariff rate under this paragraph applies to net energy billing with a distributed generation resource:
(1) With a nameplate capacity of greater than one megawatt if:
(a) The entity developing the distributed generation resource certifies by affidavit with accompanying documentation to the commission that the entity, before September 1, 2022, commenced on-site physical work of a significant nature on the distributed generation resource and the entity has made and will continue to make continuous on-site construction efforts to advance toward completion of the distributed generation resource. For the purpose of this paragraph, continuous on-site construction efforts include, but are not limited to, in the context of a solar facility, the continuous installation of racks or other structures to affix photovoltaic panels, collectors or solar cells to a site. The commission may share information contained in the affidavit submitted in accordance with this paragraph with a transmission and distribution utility, as necessary, to verify a distributed generation resource's compliance with this section. In administering this subsection, the commission may adopt rules including, but not limited to, requiring the entity that submits a sworn affidavit under this subparagraph to provide updated documentation to the commission after submission of the affidavit; or
(b) The distributed generation resource is collocated with a net energy billing customer that is or net energy billing customers that are subscribed to at least 50% of the facility's output; or
(2) With a nameplate capacity of one megawatt or less. [PL 2021, c. 659, §19 (AMD).]
A-1. The tariff rate for a customer participating in net energy billing under this section with a distributed generation resource not governed by paragraph A must:
(1) In 2022, equal the standard-offer service rate established pursuant to section 3212 that was applicable to the rate class of the customer receiving the credit on December 31, 2020 plus 75% of the effective transmission and distribution rate that was in effect on December 31, 2020 for the rate class that includes the smallest commercial customers of the investor-owned transmission and distribution utility; and
(2) Increase by 2.25% on January 1st of each subsequent year, beginning January 1, 2023. [PL 2021, c. 659, §19 (NEW).]
B. A customer participating in the program must receive for electricity delivered to the electric grid from a distributed generation resource in which the customer has a financial interest a bill credit based on the tariff rate to apply against the costs of electricity delivered to the customer by the investor‑owned transmission and distribution utility. [PL 2019, c. 478, Pt. A, §4 (NEW).]
C. A bill credit under the program as described in paragraph B may be applied to any portion of a customer's electricity bill. Credits that remain unused at the end of any billing period may be carried forward for up to one year from the end of that billing period. [PL 2019, c. 478, Pt. A, §4 (NEW).]
D. A customer participating in the program who remains eligible to participate in the program must be allowed to receive a bill credit based on the tariff rate for a period of no less than 20 years from the date of first receiving the credit. [PL 2019, c. 478, Pt. A, §4 (NEW).]
