The price of electricity in Maine coincides with the growth of solar

The statement that the amount of solar generated annually in Maine has increased nearly tenfold since 2015 is accurate, according to data and reports from the Maine Governor's Energy Office (GEO) and other sources. 
Specific data points illustrating this growth include:
  • In early 2019, Maine had 55 to 62 megawatts (MW) of installed solar capacity.
  • As of May 2025, Maine's total solar capacity reached approximately 1,000 megawatts, or 1 gigawatt (GW).
  • This represents an increase of over fifteen times the capacity from 2019 levels and an even larger increase compared to 2015. 
The significant increase in solar generation capacity has been primarily driven by state initiatives, such as the Net Energy Billing (NEB) program established in 2019, which has encouraged the development of hundreds of community solar projects and residential/commercial installations across the state
