With electricity prices varying across the U.S.—from California's high of 32.56 cents per kilowatt-hour (kWh) to Louisiana’s low of 11.50 cents per kWh—knowing what you’ll pay and how much energy you’re likely to use is crucial. In this update, we’ll break down Massachusetts current electricity rates, expected usage patterns, and tips for saving on your next energy bill.

Your electricity 'supply rate' is the price you pay for each unit of electricity you use, measured in kilowatt-hours (kWh). One kWh equals the amount of electricity it takes to power a 100-watt light bulb for 10 hours. For instance, if you see 12 cents per kWh, that’s how much the electric company charges for each unit of power. The more power you use, the more kWhs you rack up, and the higher your bill will be.

While it's hard to predict what your potential delivery charges, taxes and fees might be, we can take a look at what the supply portion of your bill is likely to cost this monthly depending on where you live. It starts with a simple calculation:
