Section 145. (a) "Eligible infrastructure replacement'', a replacement or an improvement of existing infrastructure of a gas company that: (i) is made on or after January 1, 2015; (ii) is designed to improve public health, including indoor air quality, and public safety or infrastructure reliability; (iii) does not increase the revenue of a gas company by connecting an improvement for a principal purpose of serving new customers or increasing gas pipeline capacity; (iv) reduces, or has the potential to reduce, lost and unaccounted for natural gas through a reduction in natural gas system leaks; and (v) is not included in the current rate base of the gas company as determined in the gas company's most recent rate proceeding; (vi) shall, whenever feasible, include use of advanced leak repair technology approved by the department to repair an existing leak-prone gas pipe to extend the useful life of the such gas pipe by no less than 10 years; (vii) shall, whenever feasible, include replacing gas infrastructure with utility-scale non-emitting renewable thermal energy infrastructure; and (viii) shall, whenever feasible, include zonal electrification projects through programs approved under section 145B of this chapter.

(b) A gas company shall file with the department a plan to address aging or leaking natural gas infrastructure within the commonwealth and the leak rate on the gas company's natural gas infrastructure in the interest of public safety, reducing greenhouse gas emissions pursuant to chapter 21N, and reducing lost and unaccounted for natural gas through a reduction in natural gas system leaks. In accounting for any reduction in lost and unaccounted for natural gas, a gas company shall rely on data specific to the commonwealth related to the loss of gas in transmission, storage, distribution, and use by consumers. Each company's gas infrastructure plan shall include interim targets for the department's review. The department shall review these interim targets to ensure each gas company is meeting the appropriate pace to reduce the leak rate on and to replace the gas company's natural gas infrastructure in a safe and timely manner and to reduce greenhouse gas emissions according to applicable sublimits pursuant to chapter 21N. The interim targets shall be for periods of not more than 6 years or at the conclusion of 2 complete 3-year walking survey cycles conducted by the gas company. The gas companies shall incorporate these interim targets into timelines for reducing greenhouse gas emissions and removing all leak-prone infrastructure filed pursuant to subsection (c) and may update them based on overall progress. The department may levy a penalty against any gas company that fails to meet its interim target in an amount up to and including the equivalent of 2.5 per cent of such gas company's transmission and distribution service revenues for the previous calendar year.

(c) Any plan filed with the department shall include, but not be limited to: (i) eligible infrastructure replacement of mains, services, meter sets and other ancillary facilities composed of non-cathodically protected steel, cast iron and wrought iron, prioritized to implement the federal gas distribution pipeline integrity management plan annually submitted to the department and consistent with subpart P of 49 C.F.R. part 192; (ii) an anticipated timeline for the completion of each project; (iii) the estimated cost of each project; (iv) rate change requests; (v) a description of customer costs and benefits under the plan; (vi) the relocations, where practical, of a meter located inside of a structure to the outside of said structure for the purpose of improving public safety; (vii) infrastructure proposed to be replaced or repaired, including replacement of gas infrastructure with utility-scale non-emitting renewable thermal energy infrastructure or non-combusting electric heat pumps; (viii) work plans including location by street segment with cross streets or street numbers showing where the segment of leak-prone infrastructure scheduled to be replaced or repaired begins and ends; (ix) capacity of existing infrastructure, including but not limited to, diameter and pressure of pipes; (x) how the replacement infrastructure complies with the mandates of chapter 21N and section 1A of chapter 25 to reduce greenhouse gas emissions; (xii) repairs of grade 3 leaks having a significant environmental impact as defined by section 144 (c); provided, however that such repairs shall be cost effective and shall comply with applicable state and federal safety regulations related to pipeline infrastructure; (xiii) number of customers per street segment expressing a desire to transition to non-emitting renewable sources of thermal energy; (xii) for each replacement project, an explanation, with reference to the standards developed pursuant to subsection (k), of why replacement of the infrastructure is appropriate, taking into account the cost to ratepayers and the reduction of greenhouse gas emissions as required by chapter 21N; and (xiii) any other information the department considers necessary to evaluate the plan.

As part of each plan filed under this section, a gas company shall include a timeline for repairing or removing all leak-prone infrastructure on an accelerated basis specifying an annual repair or replacement pace and program end date with a target end date of: (i) not more than 20 years from the filing of a gas company's initial plan; or (ii) a reasonable target end date considering the allowable recovery cap established pursuant to subsection (f). The department shall not approve a timeline as part of a plan unless the allowable recovery cap established pursuant to subsection (f) provides the gas company with a reasonable opportunity to recover the costs associated with repairing or removing all leak-prone infrastructure on the accelerated basis set forth under the timeline utilizing the cost recovery mechanism established pursuant to this section; provided, however, that no cost recovery or depreciation associated with gas infrastructure shall be claimed by such gas company after January 1, 2050. After filing the initial plan, a gas company shall, at 5-year intervals, provide the department with a summary of its repair or replacement progress to date, a summary of work to be completed during the next 5 years, a report of any leak-prone infrastructure remaining in the service territory of the gas company by street segment with cross streets or street numbers showing where the segment begins and ends, including the likely year of replacement of such infrastructure and the estimated cost of replacement at the current cost of replacement for the type of pipe in the location, and any similar information the department may require. The department shall require a gas company to file an updated long-term timeline as part of a plan if it alters the cap established pursuant to subsection (f).

(d) If a gas company files a plan on or before October 31 for the subsequent construction year, the department shall review the plan within 6 months. The plan shall be effective as of the date of filing, pending department review. The department may modify a plan prior to approval at the request of a gas company or make other modifications to a plan as a condition of approval. The department shall consider the costs and benefits of the plan including, but not limited to, impacts on ratepayers, reductions of lost and unaccounted for natural gas through a reduction in natural gas system leaks, compliance with the mandates of chapter 21N to reduce greenhouse gas emissions, and improvements to public health, including air quality, and public safety, and shall make written findings of factors considered. The department shall give priority to plans narrowly tailored to addressing leak-prone infrastructure most immediately in need of replacement; provided, however, that the department shall not approve a non-emergency repair or replacement of leak-prone infrastructure without an analysis of non-combusting alternatives such as non-emitting renewable thermal energy infrastructure or non-combusting electric heat pumps.

(e) If a plan is in compliance with this section and the department determines the plan to reasonably accelerate eligible infrastructure repair or replacement and provide benefits, the department shall issue preliminary acceptance of the plan in whole or in part. A gas company shall then be permitted to begin recovery of the estimated costs of projects included in the plan beginning on May 1 of the year following the initial filing and collect any revenue requirement, including depreciation, property taxes and return associated with the plan.

(f) On or before May 1 of each year, a gas company shall file final project documentation for projects completed in the prior year to demonstrate substantial compliance with the plan approved pursuant to subsection (e) and that project costs were reasonably and prudently incurred. The department shall investigate project costs within 6 months of submission and shall approve and reconcile the authorized rate factor, if necessary, upon a determination that the costs were reasonable and prudent. Annual changes in the revenue requirement eligible for recovery shall not exceed (i) 1.5 per cent of the gas company's most recent calendar year total firm revenues, including gas revenues attributable to sales and transportation customers, or (ii) an amount determined by the department that is greater than 1.5 per cent of the gas company's most recent calendar year total firm revenues, including gas revenues attributable to sales and transportation customers. Any revenue requirement approved by the department in excess of such cap may be deferred for recovery in the following year.

(g) All rate change requests made to the department pursuant to an approved plan, shall be filed annually on a fully reconciling basis, subject to final determination by the department pursuant to subsection (f). The rate change included in a plan pursuant to section (c), reviewed pursuant to subsection (d) and taking effect each May 1 pursuant to subsection (e) shall be subject to investigation by the department pursuant to subsection (f) to determine whether the gas company has over collected or under collected its requested rate adjustment with such over collection or under collection reconciled annually. If the department determines that any of the costs were not reasonably or prudently incurred, the department shall disallow the costs and direct the gas company to refund the full value of the costs charged to customers with the appropriate carrying charges on the over-collected amounts. If the department determines that any of the costs were not in compliance with the approved plan, the department shall disallow the costs from the cost recovery mechanism established under this section and shall direct the gas company to refund the full value of the costs charged to customers with the appropriate carrying charges on the over collected amounts.

(h) The department may promulgate rules and regulations under this section. Such regulations shall include a performance-based financial incentive to a gas company to reduce miles of gas infrastructure and to build utility-scale non-emitting renewable thermal energy infrastructure eligible under subsection (c)(2); provided, however, that such infrastructure complies with the mandates of chapter 21N to reduce greenhouse gas emissions. Such regulations shall be promulgated within 12 months of the effective date of this provision. The department may discontinue the replacement program and require a gas company to refund any costs charged to customers due to failure to substantially comply with a plan or failure to reasonably and prudently manage project costs.

(i) No less than 90 days before filing a plan with the department, a gas company shall notify each customer connected to leak-prone pipeline segments proposed to be replaced in such plan. Such notice shall include the available schedule of the next five years for replacement of pipeline infrastructure on the customer’s street, the expected duration, the anticipated cost for such replacement, the impact on public health including indoor air quality, public safety, the availability of cooling, and the estimated impact on the energy bill of such customer. The department shall convene a stakeholder engagement group including the department of environmental protection, the department of energy resources, the attorney general, and representatives of environmental justice communities, gas workers and environmental organizations to review and approve such outreach plan to inform customers of the pipeline infrastructure project. A gas company shall provide an opportunity to each customer connected to such leak-prone pipe to express any choice the customer may have that proposed funds be spent on installation of non-emitting renewable thermal infrastructure or non-combusting electric heat pumps instead of gas infrastructure. 

(j) Within 3 days of any plan submitted to the department by a gas company for repair, replacement or improvement of any existing infrastructure pursuant to this section, a gas company shall send such plan to the municipality whose service territory is covered by such plan, as a condition of approval by the department of such plan. Within 30 days of receipt of such plan, such municipality may provide the gas company with comments and questions about the plan. Within 15 days of receipt of such comments and questions, the gas company shall respond to questions such municipality has about the plan.  Within 3 days of approval of such plan by the department, the gas company shall send such approval to the municipality whose service territory is covered by the plan. 

(k) The department shall develop standards to inform a decision by a gas company whether to repair or replace leak-prone infrastructure. The department shall require a gas company to repair rather than replace infrastructure when conditions it specifies are met and shall conduct audits to ensure compliance with any such requirement. If a gas company replaces infrastructure required by the department to be repaired, the gas company shall not be permitted to recover the cost of the replacement for such infrastructure.

SECTION 17. Said chapter 164 is hereby amended by inserting after section 145 the following three sections:-

Section 145A. (a) By December 31, 2025, a gas company shall file with the department a plan for the transition by January 1, 2050, of such company’s pipeline infrastructure from emitting sources of thermal energy to non-emitting renewable sources of thermal energy. Such plan shall include: (i) number of customers whose source of thermal energy is projected to be transitioned each year from emitting to non-emitting sources of thermal energy;  (ii) number of miles of pipelines projected to be transitioned each year from emitting to non-emitting sources of thermal energy or which are retired from use; (iii) the thermal technology projected to be deployed by number of customers and miles of pipe transitioned including but not limited to air-source heat pumps, ground source heat pumps, networked geothermal, or other non-combusting thermal energy technology; (iv) the estimated amount of reduction in greenhouse gas emissions coming from the gas distribution system; and (v) the projected impact on a gas company’s workforce and on customers’ energy bills, affordability, and safety. Such plan shall be updated annually by December 31 of each year as provided in subsection (b) of this section.

(b) A gas company shall file annually by December 31 a update to the plan filed pursuant to subsection (a) which shall include: (i) the street segments and number of customers connected to such street segments which will transition from gas service to non-emitting renewable thermal infrastructure such as networked geothermal in the coming year; (ii) the plan in the coming year to retire gas infrastructure and to transition such customers to alternative sources of non-emitting renewable thermal energy such as non-combusting electric heat pumps; (iii) the estimated greenhouse gas emissions from existing gas infrastructure not yet scheduled for transition in the coming year; (iv) the plan to reduce greenhouse gas emissions from infrastructure determined to have no technical option to transition to non-emitting renewable thermal in the coming year; and (v) other such other information as the department may require. 

(c) In any consideration of the cost effectiveness of transitioning from existing gas infrastructure to non-emitting renewable thermal infrastructure, a gas company shall consider the following factors: (i) the leak status of the existing infrastructure; (ii) the current depreciation, schedule of future depreciation, and potential for avoided costs; (iii) the impact on public health and public safety; (iv) the potential for avoided costs; (v) the customer cost and resulting energy burden; and (vi) the expected reduction of greenhouse gas emissions as required by chapter 21N. In the interest of protecting ratepayers, a gas company may apply to the department to replace all gas appliances with electric appliances and to no longer provide gas service to the customer if cost avoidance is found to benefit ratepayers.  If the department approves such application, a gas company may replace a customer’s gas appliances with electric appliances, and may provide necessary upgrades to a customer’s electric service, insulation and mitigation of pre-weatherization barriers. Funding for such upgrades may come from funds available from energy efficiency programs pursuant to section 19 of chapter 25 or from funds available from the thermal transition trust fund pursuant to section 9A of chapter 23J.

(d) The department shall make available for review by the public plans filed by a gas company under this section.

(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.

(a) The department shall permit a gas company to sell, lease, install, and service air source heat pumps, ground source heat pumps, heat pump water heaters, induction stoves, electric clothes dryers, and other electric appliances and equipment that serve as non-combusting alternatives to gas appliances and equipment.

(b) No later than January 1, 2024, the department shall require a gas company to design and offer to each customer a plan which increases the availability, affordability, and feasibility of conversion of the customer’s gas appliances and gas equipment to electric appliances and electric equipment; provided, that the plan shall prioritize customers and zones of customers who are served by gas distribution infrastructure that is identified for replacement pursuant to section 145 of this chapter; and provided further, that such plan shall seek, whenever feasible, to convert zones of customers living in contiguous locations, rather than individual customers.

(c) In approving a plan proposed by a gas company to convert a customer’s gas appliances and gas equipment to electric appliances and electric equipment, the department shall develop a methodology for determining rates payable by a customer to a gas company that facilitates conversion from gas to electricity, including but not limited to, charges applicable only to a customer who pursues conversion from gas to electricity through such plan. The department shall permit a gas company to recover the actual costs of conversion from gas to electricity from a customer through such plan, including recovery of such costs from a customer who no longer receives gas service following conversion from gas to electricity. Any costs to be recovered shall only include the actual costs of conversion and shall not include any cost to the gas company associated with revenue lost by a gas company from the conversion by a customer from gas to electricity as a source of thermal energy. The department shall approve in advance reimbursement for costs incurred by a gas company to ensure lowest feasible cost for such conversions. A plan by a gas company to convert a customer’s gas appliances and gas equipment to electric appliances and electric equipment shall include an option for the customer to choose appliances and equipment with a higher cost than those provided through a gas company, so long as the customer pays the difference in cost between standard appliances and equipment and higher cost models. The department shall establish guidelines outlining criteria and procedures to be used by the department for reviewing a proposal, including factors the department shall consider for plan approval.

(d) A gas company may petition the department independently or in coordination with the department of energy resources to approve: (i) a financing plan for the costs of conversion from gas to electricity to be repaid by a participating customer on such gas or electric bill of such customer; (ii) other financing plans developed by a gas company; or (iii) other cost-effective plans that reasonably accelerate conversion of customers from gas to electricity; provided, that such plans will not unreasonably burden customers who remain customers of a gas company.

(e) The department shall issue a decision on a plan filed by a gas company for conversion of customers’ energy supply from gas to electricity pursuant to this section within 6 months of the date of filing such plan. A gas company shall file appropriate tariff changes and otherwise implement any plan for conversion from gas to electricity approved under this section.

(f) Participation in a plan approved under this section shall not affect a customer’s eligibility for other energy efficiency or electrification incentives available under state or federal law.

Section 145C. In any plan or other action filed by a gas company under sections 145, 145A, or 145B of this chapter that includes a plan to install a non-emitting networked renewable thermal infrastructure, such gas company shall include a plan to provide training and continued employment at pre-existing wages and benefits to workers employed by such gas company whose jobs would otherwise be eliminated or significantly changed by a transition from gas infrastructure to non-emitting renewable thermal infrastructure.

SECTION 18. Section 3 of chapter 149 of the acts of 2014 is hereby repealed.

SECTION 19. The department shall issue regulations within 12 months of the effective date of this section establishing an electric rate class for customers using air-source, ground-source and networked-geothermal heat pumps reflective of their pattern of use when determined to be of benefit to the electric grid load factor and thereby to the electric grid rate payer.
