Why Are Electric Bills in Connecticut Comparatively High?

The two factors that make up the cost an electric bill are (1) cost and (2) consumption. Looking at each, you may notice the heavily increased rate of Connecticut compared to the national average (64.7%). Keep in mind, however, that residents of Connecticut tend to use 20.8% less electricity than average.

Reasons for High Electricity Rates in Connecticut

The electrical rates in the state are no laughing matter (64.7% more than average), so it’s important to understand what makes electricity more or less expensive. The factors affecting this number are:

  1. Supplyan increase in the supply of energy brings costs down. For example, weather events such as high amounts of rain or high wind speeds can temporarily increase the supply of energy where there are hydropower plants or wind turbines to take advantage, and as a result, lower electricity rates.
  2. Demand – an increase in the demand for energy causes costs to rise. This is because the use of more costly fuels, such as natural gas, help “fill in” for the rise in demand. For example, a heat wave might temporarily increase the demand for cooling and the subsequent need for fuels, and as a result, raise electricity rates.

Additional factors that impact electricity rates include state & federal regulations, global markets and even financial speculation.

Reasons for Low Electricity Consumption in Connecticut

Because rate of electricity consumption is so low), it’s important to understand exactly what electricity is used for. The EIA looked at the end uses of electricity in the average American household and found the following breakdown:


“Other uses” includes small electric devices, heating elements, exterior lights, outdoor grills, pool and spa heaters, backup electricity generators, and motors not listed above. Does not include electric vehicle charging.

Tips for Lowering Electric Bill

  • Reduce space heating/cooling– given that heating & cooling make up a large part of the average electric bill, increasing energy efficiency in this area can have arguably the biggest impact on your bill. Here are some things you can do to reduce your usage in this area:
    • Use a programmable thermostat (can reduce heating/cooling by ~10%)
    • Use extra insulation
    • Dress up/down to the temperature
    • Replace your air filter more often
    • Check seals on windows/doors/appliances for openings/leaks
  • Reduce water heating – one of the next biggest portions of the average electric bill is from water heating, which can be reduced by showering at lower temperatures, taking shorter hot showers and by lowering the temperature on the water heater itself (ideally to 120 degrees Fahrenheit). 
  • Adjust fridge & freezer temperatures – ideally, your fridge should be at 38 degrees and your freezer at 5 degrees Fahrenheit.

Where Does Connecticut Get Its Electricity From?

The state of Connecticut counts on a mix of renewable energy sources and natural gas. According to the ELA, 43% of Connecticut’s net electricity net generation was made possible because of its Millstone nuclear power station. Among other sources of electricity are natural gas, ethanol, and oil.

One shining star of Connecticut’s electricity economy, however, is their growing use of biomass. Along with this, Connecticut has shown great strides in using clean energy. As of now, Connecticut has about 525 megawatts of solar photovoltaic generating capacity installed throughout the state.
