Springfield, MA Energy Guide: Solar, Batteries, Backup, EV

In short: in the Springfield area, your town decides your rules. Springfield is Eversource (about 29.9¢ per kWh in 2024) and Northampton is National Grid (about 33.6¢), while Holyoke’s and Westfield’s town-owned utilities charged about 16.6¢ and 17.6¢ (EIA). Holyoke Gas & Electric does not offer net metering, which changes the math for solar.

This page covers the Pioneer Valley around Springfield and Northampton. Statewide rules, including net metering for Eversource and National Grid customers, SMART 3.0, the state solar tax credit and electrician licensing, are in our Massachusetts energy guide.

Springfield area at a glance

• Eversource (Springfield, West Springfield, Agawam, Longmeadow, Ludlow, Easthampton, Amherst): about 29.9¢ per kWh in 2024 for homes on its own supply; 81 outage minutes per customer with major storms, 66 without, across Massachusetts (EIA-861, 2024).
• National Grid (Northampton, East Longmeadow, Wilbraham, Palmer): about 33.6¢ per kWh; 134 outage minutes with major storms, 91 without (EIA-861, statewide).
• Town-owned utilities: Holyoke Gas & Electric about 16.6¢ and 62 outage minutes; Westfield Gas + Electric about 17.6¢ and 123 minutes with major storms, 46 without; Chicopee about 16.2¢ and 11 minutes (EIA-861, 2024). South Hadley, Russell and Chester also have light plants (MassGIS, from DPU data).
• Sun: about 3.8 kWh per square meter per day (NASA POWER, 2001 to 2020). Our rough estimate: about 1,100 kWh a year per kW of panels.
• Top hazards: Hampden County (Springfield) is “relatively high” for cold waves, hurricanes, ice storms, inland flooding and strong wind. Hampshire County (Northampton) rates lower overall (FEMA National Risk Index, December 2025).
• Public charging: 235 ports at 77 locations in Springfield and 116 at 43 locations in Northampton (AFDC, October 3, 2026).

Your utility and what it means

• Eversource and National Grid towns: state net metering rules and SMART 3.0 apply. Both companies take part in ConnectedSolutions, which pays $275 per kW of average battery discharge during 30 to 60 summer events, locked for five years (program materials). National Grid lists East Longmeadow, Hampden and Palmer among the areas for its limited ConnectedSolutions+ offer with higher rewards. Its Charge Smart MA program pays $0.03 to $0.05 per kWh for off-peak EV charging.
• Holyoke Gas & Electric: no net metering. Instead, HG&E credits all the power your panels make at its Distributed Generation Rate, which is based on wholesale prices, and bills everything you use at the normal residential rate. That requires a second meter at $2 a month. HG&E does not allow solar power purchase agreements (PPAs), but owned or leased systems are fine. Residential systems use a simplified interconnection application with no fee, approved before installation. HG&E also says systems in light plant territory built after November 26, 2018 can’t join SMART, though you can sell renewable energy certificates (HG&E, October 2026).
• Westfield Gas + Electric: offers an on-bill battery storage rebate for systems installed in the past 12 months by a licensed contractor; its page says eligible batteries must be non-dispatchable. Check WG+E’s page for the amount. Its older MLP solar rebate is closed.
• Chicopee, South Hadley and other light plants: each sets its own rules. Ask the light department before you sign.

Supply programs: Springfield and Northampton both have municipal aggregation plans approved by the Department of Public Utilities; Northampton’s is Valley Green Energy, shared with Amherst (DPU list, May 2026). Compare supply offers on the DPU’s Energy Switch Massachusetts site.

Backup power in the Springfield area

Hampden County’s mix of ice storms, cold waves, strong wind and river flooding means the outages that matter most come with winter ice and with wind and flood storms. Utilities differ a lot: Chicopee reported about 11 minutes per customer in 2024, while Westfield’s storms pushed its total to 123 minutes (EIA-861). Keep the heat and the sump pump in mind first.

• Short outages: a portable power station handles phones, Wi-Fi, lights and medical devices.
• Heat through an ice storm: a standby generator on natural gas or propane runs longest; a home battery is quiet and automatic. Compare them in backup power, and size with the generator sizing tool or battery backup calculator.

The U.S. Consumer Product Safety Commission says to run a generator outdoors only, at least 20 feet from the house, with the exhaust away from doors, windows and vents, and never in a garage. Use battery-powered carbon monoxide alarms. A transfer switch or interlock from a licensed electrician is the safe way to connect it; see generator installation.

Solar in the Springfield area

Each kW of panels here makes roughly 1,100 kWh a year by our estimate. In Springfield, at Eversource’s 2024 average price, that offsets about $330 of purchases a year; in Northampton, at National Grid’s price, about $371 (estimates, not promises). Under state net metering, exported power earns near-retail credits, so these figures are a fair starting point.

Holyoke works differently. With power at about 16.6¢, every kWh is worth roughly half as much, and exports are credited at HG&E’s wholesale-based rate rather than retail. Ask HG&E for the current Distributed Generation Rate and have your installer show the payback on that basis. Use the solar potential tool and solar savings calculator with your own rate, and see solar installation for the process.

Batteries

For Eversource and National Grid homes, ConnectedSolutions can pay part of the cost: a battery averaging 5 kW over the summer events would earn about $1,375 a year at $275 per kW, before any share the manufacturer keeps (our arithmetic). The program materials list only Eversource, National Grid and Cape Light Compact customers, so light plant customers should ask their own utility. In Westfield, the WG+E rebate requires a non-dispatchable battery, so it suits a backup-first system. See home battery installation and battery cost.

EV charging

Home charging costs depend sharply on your utility. At about 30 kWh per 100 miles, 2024 average prices work out to roughly $5 per 100 miles in Holyoke, $5.30 in Westfield, $9 with Eversource and $10.10 with National Grid (estimates). Northampton drivers on National Grid can add Charge Smart MA’s off-peak rebates. Run your numbers in the EV charging cost calculator; a Level 2 charger needs a licensed electrician and an electrical permit, covered in EV charger installation.

Permits and inspections

• Springfield: Code Enforcement, Building Division, 70 Tapley Street, issues building and wiring permits. The city says permit review won’t exceed 30 days once all documents are in. Its electrical fee schedule lists alternate power sources (solar, generators) at 3 cents per watt for homes, $80 minimum, so about $180 for a 6 kW system; confirm the current fee.
• Northampton and other towns: the local building department and wiring inspector issue permits.
• Light plant towns: you also need the plant’s interconnection approval before installation (HG&E requires a signed application and agreement).
• Condos and HOAs: get written approval from the association first.

Springfield area energy FAQ

Does Holyoke Gas & Electric have net metering?

No. HG&E says it does not offer net metering. It credits all solar generation at its Distributed Generation Rate, based on wholesale prices, through a second meter that costs $2 a month, and bills your use at the normal residential rate. Ask HG&E for the current credit before you sign.

Is Springfield on Eversource or National Grid?

Springfield is Eversource territory; Northampton is National Grid. Holyoke, Westfield, Chicopee and South Hadley have their own municipal utilities. The state’s MassGIS utility map lists the provider town by town, and your bill names it.

What does a solar permit cost in Springfield?

The city’s electrical fee schedule lists solar and generators at 3 cents per watt for homes, with an $80 minimum, or about $180 for 6 kW. A building permit may also be needed. Confirm current fees with the Building Division at 70 Tapley Street; your installer normally pulls the permits.

Can I get SMART payments in Holyoke or Westfield?

HG&E says systems built in municipal light plant territory after November 26, 2018 are not eligible for SMART, though owners can sell renewable energy certificates. Westfield is also a light plant, so ask WG+E and check the state SMART program page before you count on any payment.
