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 HMLP’s estimated rates compare to Massachusetts’s investor-owned utility (IOU) average.
| Metric | HMLP | MA IOU Average |
|---|---|---|
| Residential Rate (est.) | $0.24/kWh | $0.28/kWh |
| Annual Cost (900 kWh/mo) | $2,592 | $3,024 |
| Ownership | Community-owned, non-profit | Shareholder-owned, for-profit |
| Rate Setting | Local board/town meeting | State PUC regulated |
| Savings vs. IOU | ~14% 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 HMLP for your exact current rate.
Understanding available incentives is key to maximizing your solar investment. Here is what HMLP 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 HMLP customers, including available incentives and projected savings over 25 years.
Projection assumes $0.24/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, 0.24/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 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 HMLP:
Monthly incentives for battery participation in peak demand events through Connected Homes program.
Incentive: $30/month per 10 kWh (battery)
Hull customers are NOT eligible for Mass Save programs. HMLP offers programs through NextZero/MMWEC.
Mass Save is funded by investor-owned utilities (Eversource, National Grid, Unitil, etc.) and their ratepayers. Municipal utilities operate independently and offer their own programs. This is a common point of confusion for homeowners in MLP towns.
The utility offers its own rebate programs for solar, heat pumps, and other efficiency upgrades (see incentives above).
Municipal utilities typically charge lower rates than IOUs, partially offsetting the loss of Mass Save rebates.
HMLP offers free energy audits to help identify savings opportunities.
Hull Municipal Lighting Plant is a municipal utility, also known as a publicly owned utility or municipal light plant (MLP). Unlike investor-owned utilities (IOUs) such as Eversource and National Grid, municipal utilities are owned and operated by the local community.
Hull Municipal Lighting Plant customers pay approximately $0.24/kWh, which is roughly 14% less than the state average for investor-owned utilities ($0.28/kWh). As a municipal utility, HMLP sets rates locally, and revenue stays in the community rather than going to shareholders.
Hull Municipal Lighting Plant does not currently list a dedicated solar rebate program. However, solar panels still make financial sense given the utility's rates and long-term energy savings. Third-party owned systems (leases/PPAs) may still qualify for the Section 48 commercial ITC claimed by the system owner.
