Maine Energy Plan

The Maine Department of Energy Resources (DOER) is required by law to update the Maine Energy Plan every two years. The Plan is informed by in-depth technical analyses and robust stakeholder input, and offers objectives, strategies, and actions to ensure affordable, reliable, and increasingly clean energy for Maine people and businesses. DOER published the most recent Energy Plan in January 2025 and will develop the next plan over the course of 2026.

About Maine’s 2027 Energy Plan 

The 2027 Maine Energy Plan will include forecasts of Maine’s expected energy needs across all sources of demand – from heating and cooling buildings, to transporting people and goods, to powering our industries and homes. The Plan will be informed by a range of recent and ongoing analyses completed by DOER and other relevant entities such as ISO New England, the Maine Public Utilities Commission and the Efficiency Maine Trust. These will include new studies directed by the Legislature examining Maine’s transmission and generation needs. In addition, the Energy Plan will be informed by robust technical analysis, developed by independent experts, to forecast energy demand and identify supply options based on the latest information about energy use, technologies, economic changes, weather patterns, and other relevant trends. 

Maine's 2027 Energy Plan will address several priorities to ensure energy is: 

  • Affordable – Maine's overreliance on fossil fuels is burdening residents and businesses with volatile energy costs. The Maine Energy Plan will document the energy spending that occurs today, exploring how that spending impacts Maine people, and identifying strategies to lower total energy costs over time. 

  • Reliable – In order to be useful, energy must be available where and when it is needed most – such as through a resilient electric grid that can withstand and recover quickly from major storms, and through adequate heating fuel supply. The Maine Energy Plan will identify and compare reliability trends and explore ways to increase reliability in the face of new challenges. 

  • Secure – Maine relies on energy that travels into and throughout the state through an interconnected system of physical infrastructure, transportation, and communications. This system must be appropriately maintained and secure.  

  • Clean – Maine is required by law to increase the portion of electricity sold in the state that comes from renewable and clean sources until that share reaches 100 percent by 2040. These laws help to reduce volatility of electricity costs, lower Maine’s reliance on expensive imported fuels, and drive job creation and investment across the state.  

How to Participate 

The Maine Energy Plan is a tool for policymakers, communities, businesses, and interested citizens across the state to understand the state’s energy situations and the opportunities available to build a stronger energy future for the state. Throughout the development of the next Energy Plan, DOER will seek public input through: 

  • A Request for Information, released in early 2026, to obtain written information and data from interested parties that can inform the Energy Plan. 

  • Public meetings and webinars in spring and summer 2026 to share draft results and gather feedback on potential recommendations to inform the final Plan.
