Southern Vermont Energy Guide: Solar, Batteries, Backup, EV

In short: Bennington and Brattleboro homes are on Green Mountain Power, at about 22.1¢ per kWh in 2024. Southern Vermont gets the most sun of the Vermont cities we checked, about 7% more than Burlington. GMP reported in 2026 that it had buried or storm-hardened 200 miles of rural lines around Brattleboro, and Brattleboro has 66 public charging ports.

Below: what Green Mountain Power offers here for solar, batteries and EVs, what its rural resilience work means for outages, and how permits work in Brattleboro and Bennington. For statewide rules (net metering rates, the plug-in solar law, tax exemptions, licensing), see our Vermont energy guide.

Southern Vermont at a glance

• Utilities: EIA lists Green Mountain Power (GMP) as the only utility in Bennington County, and GMP plus the small Village of Jacksonville municipal utility in Windham County.
• Price, 2024 average: GMP about 22.1¢ per kWh for homes (EIA-861, revenue divided by sales).
• Outages, 2024: GMP reported 667 minutes per customer with major events and 281 without, under a non-IEEE standard (EIA-861, utility-wide).
• Sun: about 3.78 kWh per square meter per day in Brattleboro and 3.74 in Bennington (NASA POWER, 2001–2020). Our rough estimate: about 1,100 kWh a year per kW of panels.
• Top hazards: FEMA’s National Risk Index (December 2025) rates Windham County “relatively moderate” for cold waves, ice storms and lightning, and Bennington County “relatively moderate” for cold waves. Both counties rate relatively low overall.
• Public charging: Brattleboro 66 public ports at 15 locations, Bennington 24 at 8 (AFDC, October 2026).

Your utility and what it means

With one utility in most of the region, your options come from GMP:

• Battery lease: two batteries for $55 a month or $5,500 upfront over ten years, shared with GMP at peak times (see our state page).
• Bring Your Own Device: $850 per kW enrolled for three-hour discharge or $950 for four hours, up to $10,500. Adding a battery to existing solar in areas where storage helps the grid most earns $100 per kW more.
• EVs: up to $1,500 on a new all-electric car ($2,500 with the income adder) through 2026, a free Level 2 charger in GMP’s home charging program, up to $500 toward installation, and two EV rates.

Backup power in Southern Vermont

GMP has made rural southern Vermont a priority. Its 2023 Zero Outages plan named rural central and southern Vermont as the hardest-hit areas to fix first. By September 2026, GMP said it had undergrounded 100 miles of line and storm-hardened another 100 across Brattleboro, Putney, Newfane, Townshend, Wilmington, Stamford and nine other towns. That covers more than 17,400 customers on 11 rural circuits and avoided about 80,000 customer outage hours. On the East Jamaica circuit, outage hours in high-wind events fell 95%. Ice still matters: a March 2025 ice storm hit parts of central and southern Vermont.

• Most homes: a home battery through GMP’s lease or BYOD gives automatic backup for the outages that remain. Size it with the battery backup calculator.
• Rural homes, wells and long outages: a generator with a transfer switch. See generator installation and the generator sizing tool.
• Apartments and condos: a portable power station.

Compare options in our backup power guide. Run generators outdoors only, at least 20 feet from the house with the exhaust pointed away, keep snow off the exhaust, and fit carbon monoxide alarms inside (CPSC).

Solar in Southern Vermont

Southern Vermont has more sun than the north. By our rough estimate, a 6 kW system makes about 6,600 kWh a year in Brattleboro and 6,500 in Bennington, about 7% more than the same system in Burlington. Used at home, that would have been worth about $1,460 a year at GMP’s 2024 average price. Net metering credits follow the state rule on our Vermont page. These are estimates, not quotes.

Check your roof with the solar potential tool and solar savings calculator, then read how solar installation works, what it costs and how net metering works.

Home batteries in Southern Vermont

A battery here does two jobs: backup and peak sharing with GMP. If you already have solar, ask whether your address is in an area where GMP pays the extra $100 per kW for a retrofit. For example, 5 kW enrolled at three hours would earn $4,250 before any extra. See battery costs and battery installation.

EV charging in Southern Vermont

At 30 kWh per 100 miles, home charging costs about $6.60 per 100 miles at GMP’s 2024 average price (our estimate), and less on its EV rates if you avoid peaks. Brattleboro has 66 public ports and Bennington 24. A Level 2 charger needs a 240-volt circuit installed by a licensed electrician. See EV charger installation and the EV charging cost calculator.

Permits and inspections

• State rule: Vermont’s Division of Fire Safety does not require a state electrical permit for owner-occupied single-family homes, but a licensed electrician must do the work and local permits may apply. Rentals and duplexes need a state electrical permit.
• Brattleboro: Planning Services requires a zoning permit for new construction that adds square footage or changes a building’s use, including decks and accessory structures. Ask whether your generator enclosure, shed or carport array needs one; Form A starts every application.
• Bennington: ask the town office about zoning or building permits before work starts.
• Net metering: solar is registered with the Public Utility Commission through ePUC and GMP.

License checks are on the state page. Check condo or HOA rules before you sign.

Southern Vermont energy questions

Is GMP burying power lines near Brattleboro?

Yes. In September 2026 GMP reported 100 miles of new underground line and 100 miles of storm-hardened overhead line across Brattleboro and 14 nearby towns, covering more than 17,400 customers. It says regulators have authorized more of this work in the hardest-hit communities.

Is solar better in southern Vermont than in Burlington?

Somewhat. NASA’s data give Brattleboro about 3.78 kWh per square meter a day against 3.53 in Burlington, so the same system makes roughly 7% more power by our estimate. Roof direction and shade still matter more than location.

Do I need a zoning permit in Brattleboro?

For new construction that adds square footage or changes a building’s use, including decks and accessory structures, yes. Call Planning Services at 802-251-8154 to ask whether your project qualifies. Electrical work must still be done by a licensed electrician.

Can I get paid for a battery in Bennington?

Yes, as a GMP customer. Bring Your Own Device pays $850 to $950 per kW enrolled, up to $10,500, in return for sharing stored energy at peaks a few times a month. You can also lease two batteries from GMP instead.
