Average electric bill in Rhode Island
Over the last 12 months the average price was 29.27¢ per kWh and the average home used 560 kWh a month, so a typical Rhode Island household spent about $164 a month on electricity, or $1,967 a year. Use is 36% below the US average of 870 kWh a month, peaking in July at 766 kWh.
Driving a Tesla Model Y Long Range AWD 1,000 miles a month takes 275 kWh from the wall (EPA 27.5 kWh/100 mi), about $80 at the state average. A 25.5 mpg gasoline car covering the same distance at $4.02 a gallon (New England (PADD 1A) average, August 2026) costs about $158.
The state average hides the real spread. Utilities in the same state charge different prices, and on a time-of-use plan the same kWh costs more in the peak hours than off-peak; each utility page shows by how much.

Natural gas for homes averaged $2.06 per therm over the 12 months to June 2026 (EIA, all charges included), and a typical gas-heated home uses about 606 therms a year for heating. The heat pump calculator compares that with electric heating on your plan.
A south-facing, 20° rooftop array in Rhode Island produces about 1,305 kWh per installed kW a year (NREL PVWatts at the state’s population center). What that is worth depends on your utility’s export rule, shown on each utility’s page.
