Reading Has a Municipal Utility — Solar Economics Are Different
RMLD charges ~$0.14/kWh vs. Eversource at $0.28/kWh. This means your solar savings are roughly half what a neighboring town like Stoneham or Woburn would see. Additionally, SMART 3.0 does not apply to municipal utility customers, and ConnectedSolutions is not available. The federal 25D ITC also expired December 31, 2025. Full MA solar guide
An 8.5 kW solar system in Reading costs $26,350-$28,900 in 2026. At RMLD's ~$0.14/kWh rate, annual electricity savings are approximately $1,428. Without SMART income and without the federal ITC, the cash payback is 17-20 years. Solar still saves money over 25 years (~$18,000 net), but the ROI is significantly lower than in IOU territories.

Prices as of March 2026. Include equipment, labor, permits, and interconnection. No federal 25D ITC ($0). No SMART income (RMLD is a municipal utility). $1,000 MA state tax credit not deducted. 6.25% sales tax exempt.
Reading's municipal utility changes the solar equation in several important ways. Understanding these differences prevents costly surprises.
RMLD's rate is roughly half of Eversource ($0.28) and less than half of National Grid ($0.32). Since solar savings are directly tied to the rate you avoid, your savings are proportionally lower. A system that saves $3,000/yr in Stoneham saves only ~$1,400/yr in Reading.
SMART only applies to IOU customers (Eversource, National Grid, Unitil). RMLD customers receive $0 in SMART income. In an IOU town, an 8.5 kW system earns ~$306/yr in SMART payments over 20 years ($6,120 total). Reading homeowners miss out on this entirely.
ConnectedSolutions battery demand response is an Eversource/NGrid program. RMLD does not participate. Eversource customers earn up to $3,250/yr with a 10 kW battery. In Reading, a battery provides backup power only — no demand response revenue.
The one advantage of RMLD: interconnection is handled locally and typically takes only ~12 business days vs. 3-4 weeks for Eversource. RMLD staff process applications in-house, which means faster activation. Total project timeline is often 4-9 weeks.
Reading homeowners still receive the $1,000 MA state tax credit (15% capped), 6.25% sales tax exemption (~$1,726), and the 20-year property tax exemption (~$310/yr). These help but do not close the gap with IOU territories.
RMLD rates have been historically stable and low. But if rates rise over time (even to $0.20/kWh), your locked-in solar production becomes more valuable. Solar acts as a hedge against future rate increases, even if today's savings are modest.
How an 8.5 kW cash-purchased system pays back at RMLD's $0.14/kWh rate.
For Context: The Same System in Stoneham (Eversource)
An identical 8.5 kW system in neighboring Stoneham (Eversource at $0.28/kWh) would save ~$2,900/yr in electricity, plus ~$306/yr SMART, plus $3,250/yr ConnectedSolutions with a battery. The IOU payback is 8-10 years vs. Reading's 17-20 years. This is not a criticism of Reading — it is the reality of having a low-cost municipal utility.
The utility you are on matters more than the town you are in. Reading's neighbors on Eversource and National Grid see dramatically faster payback.
| Town | Cost/W | Utility | Rate | Payback |
|---|---|---|---|---|
| ReadingYOU ARE HERE | $3.10-$3.40/W | RMLD | $0.14/kWh | ~17-20 yr |
| Wakefield | $3.10-$3.40/W | WMLD | $0.15/kWh | ~16-19 yr |
| Stoneham | $3.10-$3.40/W | Eversource | $0.28/kWh | ~8-10 yr |
| Woburn | $3.15-$3.45/W | Eversource | $0.28/kWh | ~8-10 yr |
| Burlington | $3.10-$3.40/W | National Grid | $0.32/kWh | ~7-9 yr |
Municipal utility towns (Reading, Wakefield) have dramatically longer payback due to lower rates and lack of SMART/ConnectedSolutions. Installation costs are similar.
Reading Building Department handles solar permits with online submission. RMLD processes interconnection locally, which is typically faster than IOUs.
Your installer submits plans online to Reading Building Department. Combined building and electrical permit. Typical fee: $50-$100. Approval: ~8 business days.
Physical installation of panels, inverter, and electrical connections. Most Reading homes are completed in 1 day. Larger systems may take 2 days.
Reading building inspector signs off. Typically scheduled within 3-5 business days of completion. No separate electrical permit needed.
RMLD handles interconnection locally — typically ~12 business days (faster than Eversource). Bi-directional meter installed. Net metering activated.
Total timeline: 4-9 weeks from contract to PTO. Reading has no historic district overlay and RMLD processes interconnection faster than IOUs. This is one clear advantage of being in municipal utility territory.
Financing matters even more in Reading because low utility rates mean slim margins. A solar loan at 6-8% APR may cost more monthly than your current RMLD bill savings.

Important: Solar Loans May Not Cash-Flow Positive
At $0.14/kWh, your annual electricity savings (~$1,428) are roughly $119/month. A solar loan at 6% APR over 15 years would cost ~$233/month. You would be cash-flow negative by ~$114/month for the loan term. If cash flow matters, a PPA at $0.10-$0.12/kWh or a cash purchase are better options in Reading.

Community solar delivers immediate savings with zero risk. While the percentage savings are modest (since your base rate is already low), there is no upfront investment and no 17-20 year payback to worry about. This is especially compelling for Reading homeowners who want clean energy without the unfavorable rooftop economics.
Solar panels in Reading cost $3.10-3.40 per watt installed in 2026. A typical 8.5 kW system costs $26,350-$28,900 before MA state incentives. The federal Section 25D residential tax credit expired December 31, 2025. You can claim the $1,000 MA state tax credit and benefit from the sales tax and property tax exemptions, but the low RMLD rate ($0.14/kWh) means payback is significantly longer than in Eversource or National Grid territories.
Honestly, solar economics in Reading are challenging. At $0.14/kWh, your annual electricity savings are roughly $1,400-$1,500 for an 8.5 kW system, which means a cash payback of 17-20 years. That is nearly double the payback of neighboring towns like Stoneham or Woburn that are on Eversource ($0.28/kWh). Solar still saves money over 25 years, but the ROI is modest. If you are motivated primarily by energy independence, environmental values, or expect rates to rise significantly, solar can still make sense.
No. SMART 3.0 (Solar Massachusetts Renewable Target) applies only to customers of investor-owned utilities — Eversource, National Grid, and Unitil. Since Reading is served by the Reading Municipal Light Department (RMLD), a municipal utility, SMART income is not available. This is a significant disadvantage compared to IOU territories where SMART adds $0.03/kWh for 20 years.
No. ConnectedSolutions is an Eversource and National Grid program for battery demand response. RMLD does not participate in ConnectedSolutions. If you install a battery in Reading, you will not earn the $275/kW summer and $50/kW winter payments that Eversource customers receive. Your battery would still provide backup power during outages.
RMLD has its own net metering policy, separate from Eversource and National Grid. Credits are applied at approximately the full retail rate ($0.14/kWh), but the specifics of excess credit rollover, annual true-up, and system size caps are set by the RMLD board rather than the MA DPU. Contact RMLD directly or have your installer verify the current net metering terms before signing a contract.
Reading Building Department handles solar permits with online submission. Typical approval takes about 8 business days. No historic district overlay applies. No separate electrical permit is needed. RMLD handles interconnection locally, which is typically faster than Eversource (about 12 business days). Total timeline from contract to activation is approximately 4-9 weeks.
This is a fair question. If RMLD rates rise to $0.20/kWh or higher, solar payback improves dramatically. However, predicting rate trajectories for municipal utilities is difficult — they are locally governed and have historically been more stable (and lower) than IOUs. If you install now, you lock in production at current costs. If rates rise, your savings increase. If they stay flat, your payback remains long but the system still generates free electricity after year 17-20.
Yes. Community solar is available regardless of your utility. You subscribe to a share of a solar farm and receive bill credits on your RMLD bill. Savings are typically 10-15% on your electricity bill with no installation required. This may actually be the most practical option for Reading residents who want solar savings without the long rooftop payback.
