In short: Troy has about 51,100 people and sits in Rensselaer County. Niagara Mohawk Power Corp. and New York State Elec & Gas Corp serves different parts of Rensselaer County, so your utility depends on your address; their 2024 home averages range from 17.22¢ to 18.32¢ per kWh (EIA). Rooftop solar here makes roughly 1,090 kWh a year per kW of panels by our estimate, which is on the modest side, so price and incentives matter more.
This page covers what is local to Troy: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our New York energy guide.
Troy at a glance
- Place: Troy, Rensselaer County, New York; about 51,065 residents (Census Bureau estimate, July 2024).
- Utility: Niagara Mohawk Power Corp. (investor-owned). Homes paid an average 17.22¢ per kWh in 2024 (EIA-861); the average customer lost 141 minutes of power on normal days and 510 counting major storms, with 1.1 interruptions a year (utility-wide, not just Troy).
- Utility: New York State Elec & Gas Corp (investor-owned). Homes paid an average 18.32¢ per kWh in 2024 (EIA-861); the average customer lost 148 minutes of power on normal days and 655 counting major storms, with 1.3 interruptions a year (utility-wide, not just Troy).
- Sun: 3.74 kWh per square meter per day on average, from 1.30 in December to 6.00 in July (NASA POWER). Our rough estimate: about 1,090 kWh a year per kW of panels.
- Climate: about 510 cooling degree-days and 7,120 heating degree-days a year (base 65°F, NASA POWER), so heating is the big load.
- Top hazards in Rensselaer County: hail “relatively moderate”, river and heavy-rain flooding “relatively moderate” and lightning “relatively moderate” (FEMA National Risk Index; overall county risk rated “relatively moderate”).
- Public charging: 177 ports at 65 locations in Troy, 4 of them DC fast (AFDC, October 20, 2026).
Your utility and what it means
Niagara Mohawk Power Corp. is an investor-owned utility and served about 1,430,208 home customers in 2024; its 17.22¢ average was below the 29.9¢ statewide average for July 2026. New York State Elec & Gas Corp is an investor-owned utility and served about 735,192 home customers in 2024; its 18.32¢ average was below the 29.9¢ statewide average for July 2026. Those are utility-wide averages, not a quote for your address; your own bill is the real number.
For reliability, New York State Elec & Gas Corp reported 148 minutes per customer without major storms in 2024, more than the statewide figure of 72 (EIA-861). Utility-wide numbers hide a lot: a home at the end of a long rural line usually has more outages than the average.
Net metering, export rates and incentives are set at state level and by each utility. Start with the New York guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Troy
- Hail (relatively moderate): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- River and heavy-rain flooding (relatively moderate): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Heating load: a winter outage can stop a furnace blower, boiler pump or heat pump. List what your heat needs to run before choosing a generator or battery.
- Short outages: a portable power station covers phones, Wi-Fi, a CPAP and lights; a home battery switches over automatically.
Size your setup with the generator sizing tool and the battery backup calculator, and compare options in backup power. Generator safety (CPSC): outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage, and battery-powered carbon monoxide alarms inside. A licensed electrician should install any transfer switch, with a permit; see generator installation.
Solar in Troy
By our rough estimate each kW of panels makes about 1,090 kWh a year in Troy (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Niagara Mohawk Power Corp.’s 2024 average of 17.22¢, that is about $188 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: July is the sunniest month at 6.00 and December the dimmest at 1.30, a 4.6-to-1 gap, so a battery or a bigger system helps in winter.
Check your own roof with the solar potential tool, see solar costs and net metering vs net billing, and read the steps in solar installation.
Batteries and EV charging
A home battery earns its place when outages are frequent, when your utility pays little for exported solar, or when evening prices are high; compare in home batteries and battery costs. Troy has 177 public charging ports in the federal station list including 4 DC fast, but home charging is cheaper and easier: see the EV charging cost calculator and EV charger installation.

Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the Troy building or permitting department, or from Rensselaer County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Troy, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the New York guide lists the state licensing rules.

Troy energy FAQ
Who is my electric company in Troy?
Niagara Mohawk Power Corp. and New York State Elec & Gas Corp both serve parts of Rensselaer County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Niagara Mohawk Power Corp. 17.22¢, New York State Elec & Gas Corp 18.32¢) so it matters for solar math.
How much power will solar make in Troy?
About 1,090 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 6,540 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Will a home battery keep my heat on in an outage?
It can keep a furnace blower, boiler pump or a heat pump running for a while, but long cold outages drain a battery fast without solar to recharge it. Pair it with a generator or wood or propane heat if outages here run for days.
Do I need a permit for solar or a generator in Troy?
Almost always an electrical permit for a transfer switch, solar or an EV charger, issued by the city or county where you live. Your licensed electrician or installer normally pulls it. Never connect a generator to your house wiring without a transfer switch.
