Summary

Origin

In June 2009, Maine enacted the Act Regarding Maine's Energy Future, which established the Efficiency Maine Trust (EMT). As a part of this Act, the Trust is responsible for creating a plan to reach a series of energy efficiency targets, which are: 

  • 100 MW reduction in peak-load electricity consumption by 2020
  • 30% reduction in electricity and natural gas consumption
  • 20% reduction in heating fuel consumption
  • Weatherization of 100% of homes and 50% of businesses by 2030
  • Capturing all cost-effective efficiency resources available for utility customers

Triennial plans must be approved by the Maine Public Utilities Commission (MPUC). The first triennial plan was approved by the Commission in July 2010, and expired at the end of 2013. The overall goals and the programs are directed at consumers rather than utilities. Reviews to the plan were approved in February 2011, and again in January 2012. The plan included a goal of saving more than 3.3 trillion BTUs of energy annually by Fiscal Year 2013. Currently, the second plan, which covers 2014-2016, has been approved by the MPUC and is in effect.

Electric and Natural Gas Sales and Demand Reductions

In pursuance of these goals, the Trust must develop triennial plans describing a three-year plan, programs, and implementation strategies for reaching these goals, as well as other energy efficiency and renewable energy goals.  The goals of the two approved plans spanning the current 2014-2016 triennial plan period, both of which are approved by the Maine Public Utilities Commission, can be seen below. There are two approved plans, given that the MACE plan is considered a "reach" goal by EMT.

Program Administrator Type

The EMT administers all the programs required for meeting the state's targets during each triennial period, and serves as Maine's "energy efficiency utility".

Cost-Effectiveness and Program Evaluation

The EMT (and the MPUC) uses the Total Resource Cost (TRC) test, one of the five "California tests" from the California Standard Practice Manual, as its primary test for evaluating the cost-effectiveness of its programs.

Utility Cost Recovery Measures

The EMT's programs are funded by a variety of funding sources, including revenues from the ISO New England Forward Capacity Market (FCM), the Regional Greenhouse Gas Initiative (RGGI) and Maine's System Benefit Charge. 

While Central Maine Power recently received permission to decouple its revenue from its sales, it is currently the only utility pursuing such an approach.
