The Efficiency Maine Trust (EMT) program budgets in its Triennial Plan for FY2020-FY2022 reflect the minimum funding allocations to low-income customers set forth in rule -- see 95-648 Code of Maine Rules (CMR) ch. 3, §3(A)(2) and 95-648 CMR ch. 4, §3(2). For the the Electric Efficiency Procurement (electric ratepayer funds) this allocation is 10%. For the Natural Gas Conservation Fund (natural gas ratepayer funds), this allocation is set at a reasonable percentage considering low-income consumers’ share of gas load and the cost-effective opportunity available at their homes. For RGGI funds, the allocation to low income programs is 10%.

One of Maine's primary electrification strategies involves a goal to install 100,000 high-efficiency heat pumps over five years. This goal was set forth in a bill passed by the Maine Legislature in 2019: LD 1766 - An Act To Transform Maine's Heat Pump Market To Advance Economic Security and Climate Objectives. The bill requires the Maine State Housing Authority to include information in its annual planning process (for low-income weatherization programs) on targets and budgets related to the heat pump goal. Efficienct Maine Trust is also offering enhanced rebates for low and moderate income households. Efficiency Maine Trust has a 50% adder in its EV rebate program for any qualifying low income Mainer who purchases/leases for any qualifying BEV or PHEV. Efficiency Maine Trust earmarked funds specifically for disproprtionately low income communities in Maine to receive ehanced rebates for level 2 charging stations.

100% of WAP and LIHEAP-Weatherization funds are dedicated to low income Mainers who meet the criteria for LIHEAP eligibility. The funds are allocated pro-rata across the nine regions served by CAP agencies in the state.

Workforce Development

The Efficiency Maine Trust (EMT) Triennial Plan for FY2020-FY2022 continues EMT's past success of promoting training for key players in the energy conservation supply chain. EMT emphasizes the certification and licensing requirements for trade allies affiliated with Efficiency Maine programs. It also considers online and in-store training opportunities, scholarships, and other support for existing programs run by community colleges.

The Maine Legislature also passed a bill in 2019 -- LD 1282: An Act to Establish a Green New Deal for Maine -- that requires employers constructing a generation facility larger than 2 MW to employ apprentices.

The Maine Cliamte Council, created by legislation signed in 2019, began meeting in 2019 is charged with developing a Climate Action Plan by December 2020 that includes a clean energy economy transition plan. Specific legislative language: "The updated climate action plan under subsection 1 must include a clean energy economy transition plan that, as applicable, incorporates feedback from the Maine Climate Council working groups established under section 577-A, subsection 7 and which may incorporate feedback from other entities with expertise in education, training, apprenticeships, workforce and labor. The clean energy economy transition plan under this subsection must:
A.  Include opportunities for and address barriers to advancing the State's clean energy economy;
B.  Highlight strategies for the State's rural communities, workers and businesses as the State transitions to a low-carbon future that are designed to encourage good-paying jobs and long-term employment; and
C.  Identify policy recommendations; opportunities for public-private partnerships; workforce development and educational opportunities, including opportunities for training and retraining workers and the development of apprenticeship programs; and other strategies necessary to the creation of clean energy jobs and a robust clean energy economy in the State."

Carbon Pricing PoliciesList All

Maine is a member of the Regional Greenhouse Gas Initiative (RGGI), a cap-and-trade program for reducing GHG emissions in North America that began its compliance period in 2009. Capping CO2 emissions from the power sector, the program aims to reduce emissions by 45% below 2005 levels by 2020 and additionally by 30% by 2030.

The Efficiency Maine Trust (EMT) reports on greenhouse gas emissions achieved RGGI-funded energy efficiency programs through two channels: (1) the annual "Investment of RGGI Proceeds" report to RGGI Inc., and (2) the RGGI Annual Report to the Maine State Legislature. Maine accounts for the avoided cost of carbon using the Avoided Energy Supply Components (AESC) report that is updated every few years. In it, the price (value) of RGGI carbon allowances is factored into the avoided costs of every kilowatt-hour saved through efficiency programs. Maine applies the AESC cost of carbon in its cost-effectiveness test which is used in establishing MACE (Maine’s study of the potential for “all cost-effective energy efficiency”) and also in its annual reports.

Public Building Requirements List All

Maine requires that construction or renovation of state buildings must incorporate green building standards that would achieve "significant" energy efficiency and environmental sustainability, provided that the costs of doing so are cost-effective over the life of the building. 

Maine Statutes Title 5, Section 1764-A also requires all planning and design for the construction of new or substantially renovated buildings owned or leased by the state include: (1) the consideration of energy efficiency, (2) an energy-use target that exceeds standards for commercial and institutional buildings by at least 20%, and (3) a life-cycle cost analysis over a minimum of 30 years that explicitly addresses the costs and benefits of efficiency improvements. 

Pursuant to a Legislative Resolve (Resolve 2009, Chapter 372), the State of Maine was charged with creating a task force to Advance Energy Efficiency, Conservation and Independence at State Facilities. The final report was issued in January 2010. The report concluded that energy efficiency, conservation and independence at the executive branch facilities of State Government should be improved by a number of means: continuing to attack and reduce consumption; conducting important and too-easily overlooked energy audits; diversifying the energy sources used at these facilities; reducing reliance on imported heating oil; and increasing the use of alternative and cost-effective renewable energy sources when possible.

In November 2019, Governor Mills signed Executive Order #13: An Order for State Agencies to Lead by Example Through Energy Efficiency, Renewable Energy and Sustainability Measures. It calls for the creation of a Sustainbility Leadership Committee to develop a baseline of energy use and greenhouse gas emissions from state operations by February 1, 2021. Every two years thereafter, the state shall report annual energy use, sources, greenhouse gas emissions, and progress on the plan to the Governor, the Legislature and post the report for the public. State agencies shall by February 1, 2021 coordinate with the Leadership Committee to develop and implement a sustainability plan to meet or exceed the state’s renewable energy and greenhouse gas reduction timelines and targets.

Encouraging CHP as a ResourceList All

CHP in Energy Efficiency Standards:  Adopted in 1999, Maine’s Renewable Resources Portfolio Requirement allows electricity generated from efficient CHP systems and other systems that qualify as "small power production facilities" under the federal Public Utility Regulatory Policies Act of 1978 (PURPA) as eligible. CHP counts toward renewable resources in the state, provided it is at least 60% efficient. Maine electricity providers must supply at least 30% of their total sales as renewable resources. In 2007, Maine created mandatory standards for new generation resources, with a goal of 10% of new energy resources to be supplied by renewable resources by 2017 and thereafter.

Production goal: Maine law requires that the utilities (through Efficiency Maine Trust) develop and procure all cost-effective, reliable and achievable energy efficiency resources (MACE) in the state (35-A MRS §§10110 and 10111). Based on the most recent MACE Potential Study, Efficiency Maine Trust is required to pursue 646,022 MWh in CHP savings over the next 10 years. The plan calls for Efficiency Maine to add incremental delivery of 42,000 MWh from CHP in 2017, 53,000 MWh in 2018, and 64,000 MWh in 2019. Qualifying CHP projects will receive from Efficiency Maine a minimum of $10,000 to a maximum of $1 million per facility or up to 50% of the total project costs.

Last Updated: July 2018

Deployment IncentivesList All

Incentives, grants, or financing: CHP is eligible for incentives through Efficiency Maine Trust’s Commercial and Industrial Custom Program, an incentive program for large electrical efficiency and distributed generation projects. This competitive program solicits proposals for projects that reduce grid supplied kilowatt hour (kWh) consumption from Maine businesses, institutions, and governments. Incentive awards range from $10,000 and $1,000,000 per project, or up to 50% of total project costs. In 2017, the program ran a limited-time bonus incentive for CHP projects, offering assistance for up to 70% of total project costs. While this bonus ended, Efficiency Maine continues to collaborate with the University of Maine-led CHP Technical Assistance Partnership center on CHP project outreach efforts.

Net Metering: All of Maine's electric utilities -- investor-owned utilities (IOUs), consumer-owned utilities (COUs, which include municipal utilities and electric cooperatives) -- must offer net energy billing (net metering) for individual customers. IOUs are required to offer net metering to eligible facilities with capacity limits up to 660 kilowatts (kW). COUs are required to offer net metering to customer-generators up to 100 kW, but, they are authorized to offer net metering to eligible facilities with capacity limits up to 660 kW at their discretion.

Net metering is available to owners of eligible, qualified facilities, including facilities generating electricity using eligible CHP systems. CHP systems must meet efficiency requirements in order to qualify for net metering: micro-CHP 30 kW and below must achieve combined electrical and thermal efficiency of 80% or greater, and micro-CHP 31 kW to 660 kW must achieve combined efficiency of 65% or greater.

Maine requires that a third party review the feasibility of non-transmission alternatives, including distributed generation such as CHP, before approving any new transmission infrastrucutre of 69 kV or more.

Customer Energy Efficiency Programs List All

All electric utility customers—both of consumer-owned and publicly-owned utilities—are eligible to receive services through the statewide programs administered by Efficiency Maine. The purposes of Efficiency Maine include consolidating the funds for Maine's consumer efficiency programs for all fuel types; integrating delivery of electric and thermal efficiency measures to consumers; acquiring customer-sited energy resources (efficiency and alternative energy) at lower cost than traditional energy supply; and helping to transform the energy market in Maine by providing consumers with more efficient, affordable products and energy services. All utilities contribute funding to the programs.

Natural gas programs are also administered by Efficiency Maine and serve commercial, industrial, and residential customers, including low-income residential customers. State statute was amended as part of the Omnibus Energy Act passed in 2013, to extend these programs to each natural gas utility in the state.

By rule, at least 10% of funds must support energy programs for low-income residents, and at least 20% of funds must support energy programs for small business customers. Historically, the PUC has assessed utilities to collect funds for energy programs and administrative costs. In addition, Efficiency Maine manages money from the Regional Greenhouse Gas Initiative (RGGI) and grants, such as those received from the Federal government's American Recovery Reinvestment Act (ARRA) in 2010. The funds for natural gas conservation programs are collected through a rate surcharge.

The most recent budgets for energy efficiency programs and electricity and natural gas savings can be found in the State Spending and Savings Tables.

Energy Efficiency as a Resource List All

The Maine statute establishes the requirement that utilities procure "all cost-effective energy efficiency" by funding Efficiency Maine Trust programs at levels sufficient to meet that standard.  See 35-A MRS 10104(4).  Also, the newly established Non-Wires Alternative law establishes an independent Coordinator to analyze all transmission and distribution proposals over $500,000 to determine if NWA resources, including energy efficiency, are the more cost-effective resource and, if so, to effectuate the procurement of that resource.  See 35-A MRS 3132-C.

Also, Maine has had a loading order that requires utilities to use energy efficiency before any other traditional resource (35-A MRS 3210-C (4)) when securing energy resources by means of long-term contracts. In March 2010, the Governor signed Public Law Chapter 518, An Act To Enhance Maine's Clean Energy Opportunities. It goes beyond previous policy to set the goal for Efficiency Maine as “capturing all cost-effective energy efficiency resources available for electric and natural gas utility ratepayers”.

Efficiency Maine plans energy efficiency programs in three-year increments. The second Triennial Plan, from fiscal year 2014-2016, was approved by the MPUC in March 2013 (see Docket No. 2012-00449). The third Triennial Plan covering fiscal years 2017-2019 was approved in 2016.

Summary: Annual savings targets of ~2.3% for electric and 0.1% for natural gas for 2020-2022.

The Maine Public Utilities Commission (MPUC) approved the fourth Triennial Plan of Efficiency Maine, which develops, plans, coordinates, and implements energy efficiency programs in the state. The fourth Triennial Plan sets annual savings targets for 2020-2022 of 2.3% for electricity and 0.1% for natural gas, along with additional savings targets for other fuels.

The 10- and 20-year targets established by statute are far-reaching and were incorporated into the strategy and budgets of the Triennial Plan. Targets were revised in 2013, when Maine legislators overrode the governor’s veto to pass LD 1559. Targets include capturing all cost-effective energy efficiency (both electricity and natural gas); reducing electricity and natural gas consumption 20% by 2020; reducing oil heating use 20% in the same timeframe; and conducting weatherization of all homes for which homeowners are willing to share the costs of cost-effective weatherization to a minimum standard.

The independent evaluation of ratepayer-funded energy efficiency programs in Maine is required by statute (Title 35a Section 10104 subsection 10). Evaluations are administered by Efficiency Maine. Requirements for these evaluations in Maine are articulated in Code of Maine Rules 65-407, Ch. 380 transferred to Code of Maine Rules 95-648, Ch. 380. Statewide evaluations are conducted

According to the Database of State Efficiency Screening Practices (DSESP), Maine relies on the Total Resource Cost Test (TRC) and considers it to be its primary cost-effectiveness test. Maine’s TRC accounts for avoided fossil fuel and supply water and wastewater processing costs. Economic development, job creation, productivity improvements, and environmental benefits are included to the extent they can be quantified and valued. Maine also has a target of 10% of available program funds or $2.6 million, whichever is greater, to low-income programs.

Guidelines for Low-Income Energy Efficiency Programs List All

Requirements for State and Utility Support of Low-Income Energy Efficiency Programs

LD-1559, passed in June 2013, states that Efficiency Maine Trust shall “target at least 10% of funds for electricity conservation collected under subsection 4 or 4-A or $2,600,000, whichever is greater, to programs for low-income residential consumers, as defined by the board by rule.” Efficiency Maine Trust is the independent administrator for energy efficiency and alternative energy resources programs in Maine and is funded primarily by electric and natural gas utilities, as well as the sale of carbon allowances under the Regional Greenhouse Gas Initiative (RGGI). Efficiency Maine Trust delivers energy-saving opportunities to low-income (LIHEAP-eligible) customers through four initiatives: consumer products (rebates and markdowns), HESP (weatherization and heating systems), food pantry light bulb distribution, and supplementation of Community Action Agency direct installation initiatives.

Following the passage of LD 1766 in 2019 and its establishment of a state-wide goal to install 100,000 high-performance heat pumps by 2025, MaineHousing allocated a portion of its annual LIHEAP weatherization budgets to pay for the installation of 1,000 heat pumps/year in LIHEAP-eligible homes. 

Cost-Effectiveness Rules for Low-Income Energy Efficiency Programs

Maine does not have specific cost-effectiveness guidelines in place for low-income programs. However, the cost-effectiveness test for all programs requires consideration of non-energy benefits including “…reduced operations and maintenance costs, job training opportunities and workforce development, general economic development and environmental benefits, to the extent that such benefits can be accurately and reasonably quantified and attributed to the program or project.”

Coordination of Ratepayer-Funded Low-Income Programs with WAP Services

The Maine State Housing Authority administers the federal Weatherization Assistance Program (WAP) for the state. State regulations require the Housing Authority to ensure effective coordination of WAP with the Housing Authority’s Central Heating Improvement Program (CHIP)—which finances energy-related repairs for low-income homeowners—as well as with other bill assistance programs. 2009 Public Law Chapter 372 requires that the Housing Authority must also coordinate WAP plans and use of federal DOE funds with the programs administered by Efficiency Maine Trust.

Self Direct and Opt-Out Programs List All

Pursuant to Title 35-A MRSA §10110 (6), large electricity customers receiving service at transmission and subtransmission (T&ST) voltage levels are not required to pay in rates any amount associated with any procurement of energy efficiency resources by transmission and distribution utilities. Consequently, these customers are not eligible for incentives that leverage the Electric Efficiency Procurement funds through the Efficiency Maine Trust. Instead, electric efficiency incentives for these customers are funded with Forward Capacity Market (FCM) revenues, Maine Power Reliability Program (MPRP) Settlement, or RGGI funds.

Until recently, Maine’s largest natural gas customers, whose usage exceeded 1 million centum cubic feet (CCF) of natural gas annually, were exempt from contributing to the Natural Gas Efficiency Procurement; as such, they were not eligible for the Trust’s natural gas efficiency programs. However, in the spring of 2017, the Legislature amended the law once again, codifying the inclusion of large, non-generator, users. It maintained a limited exclusion for large manufacturers, agricultural, and aquaculture businesses; from FY2018 forward, these customers pay the natural gas assessment on their first 1 million CCF of usage and are eligible for the Trust’s natural gas efficiency programs. (See 35-A MRSA §10111(2)).

Requirements for Provision of Energy Data

Maine requires the provision of individual meter data to customers in an electronic format and to third parties upon authorization of the customer. Data is generally provided via spreadsheet through secure electronic transfer. Utilities cannot disclose customer information except for debt collection, credit reporting, usage reporting pursuant to state and federal law, law enforcement requests, and in response to a Commission Order. Third-party eligibility depends on whether or not the party falls into one of these exemptions. Efficiency Maine has been granted access to individual meter data through a Commission Order.

Energy Use Data Availability

Energy use data may be requested by Efficiency Maine by submitting the request to the Maine Public Utilities Commission. The Commission will issue a Protective Order that ensures the confidentiality of the data. Efficiency Maine has the authority to request this data under the Efficiency Maine Trust Act (35-A M.R.S.A. §10104(4)(A)(1)).
