Municipal utilities typically offer lower electricity rates because they operate as non-profit, community-owned entities. There are no shareholders to pay, and local governance keeps costs in check. Here is how KL&P’s estimated rates compare to Maine’s investor-owned utility (IOU) average.
| Metric | KL&P | ME IOU Average |
|---|---|---|
| Residential Rate (est.) | $0.23/kWh | $0.27/kWh |
| Annual Cost (900 kWh/mo) | $2,484 | $2,916 |
| Ownership | Community-owned, non-profit | Shareholder-owned, for-profit |
| Rate Setting | Local board/town meeting | State PUC regulated |
| Savings vs. IOU | ~15% lower rate = ~$432/yr savings | |
Rates shown are estimates based on publicly available data. Municipal utility rates can change based on local board decisions. Even with lower rates, solar panels still provide significant savings by reducing or eliminating your electric bill. Contact KL&P for your exact current rate.
Understanding available incentives is key to maximizing your solar investment. Here is what KL&P customers can access in 2026.
The federal residential solar ITC expired on December 31, 2025. Homeowners who purchase solar panels with cash or a loan no longer receive a federal tax credit. However, third-party owned systems (solar leases and PPAs) may still qualify under Section 48/48E, with the financing company claiming the credit. This makes local utility rebates more valuable than ever.

Here is what a typical 8 kW residential solar installation looks like for KL&P customers, including available incentives and projected savings over 25 years.
Projection assumes $0.23/kWh rate with no annual increase (conservative estimate). Actual savings may be higher as rates typically increase 2-4% per year.
With a solar lease or power purchase agreement (PPA), a third-party company owns the system on your roof. The system owner can still claim the 30% federal ITC under Section 48/48E, which often results in lower monthly payments for you. You pay a fixed monthly rate or per-kWh price that is typically lower than your utility rate, with no upfront cost.

Estimates based on 1250 kWh/kW annual production, 0.23/kWh utility rate, and 0.5% annual panel degradation. Federal residential solar tax credit (Section 25D) expired Dec 31, 2025. Actual results vary by roof orientation, shading, and usage patterns.
Net metering at retail rate with monthly credit rollover.
Net metering is the billing mechanism that makes rooftop solar financially attractive. When your solar panels produce more electricity than your home uses, the excess flows back to the grid and your meter effectively “runs backwards.” Here is the typical process with KL&P:
Bill credits for reducing usage during peak demand events.
Incentive: $25/event
