SECTION 1. Chapter 25A of the General Laws, as appearing in the 2014 Official Edition, is hereby amended by inserting after section 11I the following section:-

Section 11J.   (a) The department shall establish a solar incentive program for the development of distributed solar generation beyond 1,600 megawatts direct current by solar photovoltaic facilities connected to a distribution or transmission system, which shall be a statewide program.  Said program shall be designed by the department and may include a tariff implemented by the distribution companies, to be reviewed and approved by the department of public utilities.  In designing the program, the department shall: (i) promote an orderly transition to a stable, equitable, and self-sustaining solar market at a reasonable cost to ratepayers; (ii) promote equitable access to solar energy; (iii) take into account other incentives, credits, or revenue available to developers and owners of different classes of projects; and (iv) ensure that the costs of the program are shared collectively among all ratepayers of the distribution companies. The incentive program developed pursuant to this Section 1 shall take effect upon the date of notification by the department of energy resources that 1,600 MW direct current of solar generation has been qualified under subsection (g) of section 11F of chapter 25A.

(b)  Attributes, as defined by the department, of the solar photovoltaic facilities receiving incentives under this section shall be eligible for use by retail electric suppliers pursuant to their obligations under section 11F of chapter 25A.

(c) The department shall set forth provisions in its regulations specifying that the program implemented in accordance with paragraph (a) shall not apply to solar generation projects qualified under subsection (g) of section 11F.

(d) Any solar photovoltaic facility that has an alternating current nameplate capacity rating greater than 10 kilowatts for single phase service or greater than 25 kilowatts for three-phased service participating in the incentive program established by this subsection, if otherwise eligible to be a net metering facility pursuant to sections 138 and 139 of chapter 164, shall be subject to subsection b ½ of section 139 of chapter 164.

(e) The department may establish a separate incentive program for non-solar photovoltaic generation units eligible under the renewable portfolio standard pursuant to section 11F

SECTION 2.  Section 138 of chapter 164 of the General Laws, as appearing in the 2014 Official Edition, is hereby amended by inserting the following definitions:

“Cap allocation,” an allocation of capacity under the applicable net metering cap granted by the system of assurance of net metering eligibility, which indicates that the capacity of the net metering facility will be eligible to receive net metering services upon receipt of authorization to interconnect pursuant to section 139(g). 

“Market-based net metering credit,” a credit equal to the excess kilowatt-hours by time of use billing period, if applicable, multiplied by the average monthly energy clearing price in the ISO-NE zone in which the net metering facility is located; provided, however, (i) net metering facilities of a municipality or other governmental entity, (ii) eligible recipients of credits from net metering facilities serving low income customers as such customers are defined by the department of energy resources pursuant to section 11J of chapter 25A, and (iii) eligible recipients of credits from community shared net metering, as defined by the department of energy resources pursuant to section 11J of chapter 25A, shall receive a credit equal to the basic service kilowatt-hour charge in the ISO-NE load zone where the customer is located.

“System of assurance,” the system of assurance of net metering eligibility created by the department to (i) track the aggregate capacity of all net metering facilities; and (ii) provide prospective net metering facilities and other stakeholders with an assurance, before beginning construction, that a facility is eligible to receive net metering services once it is able to generate electricity.

SECTION 3.  Section 139 of said chapter 164, as so appearing, is hereby amended by inserting after subsection (b) the following subsection:

(b ½) (1) A net metering facility that has an alternating current nameplate capacity rating greater than 10 kilowatts on a single phase circuit or greater than 25 kilowatts on a three-phased circuit and receives a cap allocation under subsection (g) after the date of notification by the department of energy resources that 1,600 MWs direct current of solar generation has been qualified under subsection (g) of section 11F of chapter 25A, shall accrue market-based net metering credits and shall not be eligible for any other net metering credits as otherwise provided in this section. If the electricity generated by a net metering facility during a billing period exceeds the customer’s kilowatt-hour usage during the billing period, the customer shall be billed for zero kilowatt-hour usage and the excess market-based net metering credits shall be credited to the customer’s account. Credits may be carried forward from month to month. A net metering facility may designate customers of the same distribution company to which the net metering facility is interconnected and that are located in the same ISO-NE load zone to receive such credits in amounts attributed to such customers by the net metering facility.

(2) In the instance of any net metering facility of a municipality or governmental entity, a distribution company may elect not to allocate such credits and instead may purchase net metering credits from the facility at the applicable net metering credit value.

(3)  A net metering facility that has an alternating current nameplate capacity that is equal to or less than 10 kilowatts on a single phase circuit or 25 kilowatts on a  three-phased circuit shall be entitled to receive net metering credits as otherwise provided under this section, regardless of the time of interconnection to the distribution system. Larger projects shall not be segmented into smaller capacity projects to achieve eligibility under this rule.

SECTION 4.  Section 139 of said chapter 164, as so appearing, is hereby further amended by  striking out subsection (f) and inserting in place thereof the following subsection:-

(f) The aggregate net metering capacity of net metering facilities that are not net metering facilities of a municipality or other governmental entity shall not exceed 6 percent of the distribution company’s peak load. The aggregate net metering capacity of net metering facilities of a municipality or other governmental entity shall not exceed 7 percent of the distribution company’s peak load.  The department shall have the authority to increase such caps if it finds an increase to be in the public interest. The department shall be authorized to condition any increases or otherwise limit the applicability to project classifications, as it may deem appropriate. The maximum amount of generating capacity eligible for net metering by a municipality or other governmental entity shall be 10 megawatts. For the purpose of calculating the aggregate capacity, the capacity of a solar net metering facility shall be 80 percent of the facility’s direct current rating at standard test conditions and the capacity of a net metering facility that is not a solar net metering facility shall be the nameplate rating.

SECTION 5. Section 139 of said chapter 164, as so appearing, is hereby further amended by adding the following subsection:-

(j) An operational net metering facility eligible under sections 138 and 139 of this chapter shall continue to be eligible to receive net metering credits as otherwise provided under this section if it has received a cap allocation prior to the date of notification by the department of energy resources that 1,600 MWs direct current of solar generation has been qualified under subsection (g) of section 11F of chapter 25A.  Provided, however, at the expiration of twenty years from the date upon which the net metering facility was authorized to interconnect by the distribution company, said net metering facility shall accrue market-based net metering credits.

SECTION 6.  The department of energy resources shall issue public notice upon the qualification of 1,600 MW direct current of solar generation under subsection (g) of section 11F of chapter 25A.

SECTION 7.  The incentive program developed pursuant to Section 1, and the provisions of Section 3 shall take effect upon the date of notification by the department of energy resources, pursuant to section 6 of this act, that 1,600 MW direct current of solar generation has been qualified under subsection (g) of section 11F of chapter 25A.

SECTION 8.  An operational facility previously eligible under sections 138 and 139 of chapter 164 of the General Laws or qualified as a renewable generating resource for a program under subsection (g) of section 11F of chapter 25A shall not lose said eligibility or qualification so long as it remains in compliance with applicable eligibility or qualification requirements.

SECTION 9.  The invalidity or unenforceability of any provisions of this act shall not affect the validity or enforceability of any other provision of this act, which shall remain in full force and effect.
