(A) for the portion of a non-emitting renewable thermal infrastructure project that is financed by gas transition bonds, the difference in interest rate for such bonds and the interest rate on debt approved for other projects in the plan filed by a gas company pursuant to subsection (b) of section 145. If a plan filed pursuant to subsection (b) of said section 145 proposes only to use gas transition bonds for a non-emitting thermal infrastructure project, then the interest rate for such bonds shall be compared to the most recent interest rate on debt approved by the department for such gas company; and

(B) for the portion of a non-emitting renewable thermal infrastructure project that is financed by gas transition bonds but would otherwise be financed by the equity of a gas company, the difference between the interest rate for such gas transition bonds and the return on equity approved for other projects in the plan filed by a gas company pursuant to subsection (b) of said section145. If a plan filed pursuant to subsection (b) of said section 145 proposes only to use gas transition bonds for a non-emitting renewable thermal infrastructure project, then the return on equity shall be calculated as the most recent return on equity approved by the department for such gas company.

(2) For purposes of calculating cost savings under subsection (d)(1)(ii) of this section, a gas company may use the interest rates for debt and return on equity proposed in the plan filed pursuant to subsection (b) of said section 145.

(g) All cost savings generated by the use of gas transition bonds by a gas company shall be deposited by the department into the Gas Transition Trust Fund established under section [9A] of chapter 23J, and shall be used for the purposes outlined in section [9A] of chapter 23J.  A gas company shall provide the department and Massachusetts clean energy technology center details of an approved non-emitting renewable thermal infrastructure project, including the number of participating consumers and buildings and such other information requested by the Massachusetts clean energy technology center to determine the costs to install appliances and upgrade buildings to connect consumers and buildings to a non-emitting renewable thermal infrastructure project.

(h) A gas company shall submit an annual report to the department regarding the company’s use of gas transition bonds.  Such report shall include: (i) the costs and cost savings associated with the use of gas transition bonds; (ii) the total number of square footage of buildings transitioned to each non-emitting renewable thermal infrastructure project; (iii) the total number of consumers transitioned to each non-emitting renewable thermal infrastructure project; (iv) the number of low-income consumers transitioned to each non-emitting renewable thermal infrastructure project; (v) the impact of a non-emitting renewable thermal infrastructure project on greenhouse gas emissions, public health, ratepayer bills, and the reliability and safety of the thermal delivery system of such gas company; and (vi) such other information as required by the department. If a social cost of carbon is adopted by the secretary, such social cost of carbon shall be included in the calculation of costs and savings. Such annual reports may, under the discretion of the department, be incorporated into other filings by a gas company, provided that such reports shall be available for review by the public.

(i) Three years following the enactment of this section, the department shall collate data collected pursuant to subsection (h) of this section and shall file a report with the governor, the secretary of energy and environmental affairs, and the clerks of the house of representatives and the senate who shall forward such report to the president of the senate, the speaker of the house of representatives, the chairs of the house and senate committees on ways and means, and the house and senate chairs of the joint committee on telecommunications, utilities and energy on the use of gas transition bonds for non-emitting renewable thermal infrastructure projects. The department shall include in such report data collected by the Massachusetts clean energy technology center data on the use of funds pursuant to subsection (g) of this section.

(j) Three years following the enactment of this act, the secretary of energy and environmental affairs, in consultation with the department of public utilities, the department of energy resources, and the attorney general, shall determine whether the use of gas transition bonds should be expanded.  When making this determination, the secretary shall consider: (i) the maximum amount of gas transition bonds that can be utilized; (ii) the types of projects that can be financed with gas transition bonds; (iii) additional use of funds for a non-emitting renewable thermal infrastructure project from (A) the MassSave program pursuant to section 19 of chapter 25, (B) the Massachusetts Clean Energy Technology Center, or (C) the department of energy resources; and (iv) other conditions as determined by the secretary.  The determination by the secretary shall be made in a proceeding that is open to comment by the public.

(c) The department may promulgate regulations or directives as needed to implement this section.

SECTION 53. Chapter 164 of the General Laws is hereby amended by inserting after section 147, the following new section:-

Section 147A. (a) For the purposes of this section, the following words shall have the following meanings:-

“Non-emitting renewable thermal infrastructure project,” a utility-scale project that replaces natural gas distribution infrastructure with distribution infrastructure that supplies heating, or heating and cooling, from fuel sources whose combustion does not emit greenhouse gases, as defined by section 1 of chapter 21N.  A non-emitting renewable thermal infrastructure project may include, but is not limited to, a networked geothermal system.


(b) a gas company shall submit an annual report to the department regarding the company’s plan to transition its existing gas infrastructure to non-emitting renewable thermal infrastructure projects that advance the greenhouse gas emission reduction requirements of chapter 21N of the General Laws. Such report shall include the following information: (i) the company’s plan to abandon existing gas infrastructure that is not cost effective to transition to a non-emitting renewable thermal infrastructure project; (ii) the company’s plan to evolve existing gas infrastructure that is cost effective to transition to a non-emitting renewable thermal infrastructure project; (iii) the company’s plan to (A) maintain existing gas infrastructure that provides service to a use for which, at the time that the report is prepared, there is no technical option to transition to a non-emitting renewable thermal infrastructure project and (B) reduce greenhouse gas emissions from existing gas infrastructure that the gas company plans to maintain; and (iv) such other information as the department may require. 

(c) In determining whether it is cost effective to transition existing gas infrastructure to non-emitting renewable thermal infrastructure, a gas company shall consider factors such as the existing infrastructure’s leak status, current depreciation, schedule of future depreciation, impact on public health and public safety, and the impact of transitioning to a non-emitting renewable thermal infrastructure on the reduction of greenhouse gas emissions as required by chapter 21N.

(d) A report required by subsection (b) may, under the discretion of the department, be incorporated into other filings by a gas company, provided that such reports shall be available for review by the public.

(e) The department shall, within 12 months of the enactment of this section, promulgate regulations or directives as needed to implement the requirements of this section.
