Average Electric Bill in Maine (2026)

Maine Electricity Cost Comparison

Electricity Rates in Maine Are Rising

Electricity rates across the United States have been increasing at an average of 2.5% per year, and Maine is no exception. At the current rate of 27.78¢/kWh, your average monthly bill of $246 could grow to $278/month within 5 years and $315/month within 10 years — that's an increase of $69/month without changing your usage habits at all.

Solar energy effectively locks in your electricity cost at today's prices. Once your system is installed and paid off, the electricity it produces is free for the remaining lifespan of the panels (25-30+ years). This hedge against rising rates is one of the most compelling financial arguments for going solar, especially in states like Maine where rates are already well above the national average.

Maine homeowners with solar typically reduce their electricity bills by 70-100%, saving approximately $2509 per year. Over the 25-year lifespan of a solar system, total savings in Maine typically range from $$50,180 to $$75,270 when factoring in rate increases.

How Solar Reduces Your Maine Electric Bill

When you install solar panels, they generate electricity during daylight hours that directly powers your home. Any excess electricity is typically sent back to the grid through net metering, earning you credits on your utility bill. Maine offers full retail net metering, meaning you receive full credit for every excess kWh — this maximizes your savings.

With 4.1 peak sun hours per day in Maine, a properly sized 8kW solar system produces approximately 11,972 kWh per year — enough to offset most or all of an average Maine household's electricity consumption.

The best way to determine exactly how much solar can save on your specific Maine electric bill is to get a personalized quote from a licensed installer. They'll analyze your actual usage data, roof conditions, and local utility policies to provide an accurate savings projection.
