Average monthly electric bill

The average monthly electric bill in Connecticut is $327 for residential customers. This is calculated by multiplying the average monthly consumption by the average electric rate: 996 kWh * $0.33/kWh. The average electric rate in Connecticut is $0.33 per kilowatt-hour (kWh), which is 64% higher than the national average of $0.15/kWh. Connecticut residents use approximately 20% less electricity than the national average, with an average monthly consumption of 716 kWh compared to the national average of 899 kWh.

The monthly electric bill in Connecticut can be broken down into four components: Supply, Transmission, Local Delivery, and Public Benefits. The Supply portion reflects the cost of electricity generation and includes the Generation Services Charge (GSC) and the Bypassable Federally Mandated Congestion Charge (BFMCC). The Transmission portion covers the price of delivering electricity over high-voltage power lines, while the Local Delivery part is regulated by the Public Utilities Regulatory Authority (PURA) and includes distribution investments. The Public Benefits component covers costs related to grid reliability, affordability, clean energy, and other energy policy directives.

Electricity rates in Connecticut are expected to increase by 5.5% annually. Over the next 25 years, residents can expect to pay an average of $201,000 on electric bills. However, there are ways to reduce the cost of electricity bills, such as installing a solar system. On average, it takes about 8.83 years for a solar investment to pay off in Connecticut, after which residents may eliminate their electric bills completely.

The average electric bill can also vary depending on the type of residence. For example, the average electric bill for a one-bedroom apartment in Connecticut is approximately $113 per month for a single occupant, but it can increase by $57 or more if there are roommates in a three-bedroom apartment. Additionally, the number of appliances and electronics, as well as the usage habits of roommates, can significantly impact the total electric bill.

Variable charges

The total cost of your electricity bill is calculated by multiplying your monthly consumption by the electric rate. For example, with a monthly consumption of 716 kWh and a residential electric rate of 26.00 ¢/kWh, the average electric bill in Connecticut is $186.16.

Your electricity rate will depend on your supplier and the type of plan you choose. For example, Constellation offers a 6-month plan at 9.29 ¢/kWh, while their 36-month plan is 11.99 ¢/kWh.

You can also choose to use a third-party electricity supplier, which may increase or decrease the cost of your electricity supply. Additionally, you can reduce your electric bill by using less electricity or investing in a solar system.

If you're on a demand charge electric rate, your bill will be based on the maximum amount of power you use over a single time period (such as an hour or fifteen minutes) in a given month. In this case, the best way to reduce your bill is to decrease the amount of electricity you use all at once, such as by installing a solar system.

Energy-efficiency programs

In Connecticut, the average monthly electric bill for residential customers is $327, calculated by multiplying the average monthly consumption by the average electric rate. This is expected to decrease by $13.50 starting in May 2025. The bill is divided into four components: supply, transmission, local delivery, and public benefits.

Energy efficiency programs in Connecticut include:

  • EnergizeCT: This program offers smart energy-efficient recommendations by assessing your facility and usage. They provide energy audits for homes and businesses, helping you understand your current energy usage and recommending cost-saving solutions. They also offer rebates and incentives for energy efficiency upgrades such as insulation, heat pumps, and appliances. Commercial financing options are available for business owners. The Weatherization Assistance Program, funded by the US Department of Energy, assists low-income households in minimizing energy-related costs and fuel usage through retrofits and home improvements.
  • Connecticut Energy Efficiency Fund: Administered by Eversource Energy Service Company and United Illuminating, Connecticut Natural Gas, and Southern Connecticut Gas subsidiaries of AVANGRID, Inc. The fund issues proposals for the CT Retro-Commissioning (RCx) Program, which aims to increase awareness among building owners and operators about operating inefficiencies and implement corrective measures to achieve energy savings. The program focuses on improving control strategies and operating procedures rather than major capital equipment investments.
  • Solar power: Installing a solar system can help reduce or eliminate your monthly electric bill. The payback period for a solar system in Connecticut is about 8.83 years, after which you may start earning money from your investment.
  • Time-of-use electric rates: This plan incentivizes customers to use less electricity when the cost of generation is high. It follows a set schedule, with higher rates during periods of high demand and generation costs (e.g., the afternoon on a hot summer day) and lower rates during periods of low demand and costs (e.g., the middle of the night).

Solar systems

When it comes to solar systems and understanding electrical demand in Connecticut, there are a few key concepts to grasp. Solar systems have gained popularity as a renewable energy source and an alternative to traditional electricity in the state. Here's a direct and instructive guide:

Connecticut encourages the adoption of solar power as a renewable energy source to meet its energy goals. Solar systems use photovoltaic (PV) technology to convert sunlight directly into electricity. The amount of electricity generated by a solar system depends on various factors, including the size and angle of the panels, sunlight exposure, and efficiency of the system.

When installing a solar system, it's essential to consider the electrical demand of your household or business. Electrical demand refers to the rate at which electricity is consumed over a specific time period. It is usually measured in kilowatts (kW) and represents the amount of power required to operate all electrical devices and appliances simultaneously.

To calculate electrical demand for a solar system in Connecticut, you need to consider the following steps:

  • Assess your energy usage: Start by understanding your historical energy consumption patterns. Review your past electricity bills to determine the amount of electricity you typically consume monthly or annually. This information will help you gauge the size and capacity of the solar system you'll need.
  • Consider your peak demand: Electrical demand is often highest during specific periods, such as hot summer days when air conditioning is in use. Analyze your past bills to identify the months or seasons when your electrical demand peaks. This information will influence the design and orientation of your solar panels to maximize energy capture during these critical periods.
  • Size your solar system accordingly: The capacity of your solar system will depend on your average and peak energy demands. Typically, solar panels are sized in kilowatts, representing the amount of electricity they can generate under standard test conditions. A qualified solar installer can assist in calculating the number and wattage of panels required to meet your specific demand.
  • Understand net metering: Connecticut offers net metering programs, which allow solar system owners to receive credit for excess electricity generated and fed back into the grid. This can help offset the costs of electricity drawn from the grid during periods of low solar generation, such as at night or on cloudy days. Understanding net metering policies can influence the sizing and economics of your solar system.
  • Consider energy storage: Solar energy is intermittent, and energy storage solutions, such as batteries, can help store excess energy generated during sunny periods for use during peak demand or when solar generation is lower. Energy storage can further reduce your reliance on grid electricity and provide backup power during outages.

By carefully considering your electrical demand and working with qualified solar installers, you can design a solar system that meets your energy needs and reduces your carbon footprint. Remember to also stay updated with Connecticut's solar incentives and rebates to make the most of your investment in solar power.

Demand charge electric rate

In Connecticut, the average monthly electric bill for residential customers is $327, calculated by multiplying the average monthly consumption by the average electric rate. The bill is divided into four components: Supply, Transmission, Local Delivery, and Public Benefits.

The Supply portion reflects the cost of electricity generation, which is deregulated. The Transmission part reflects the price for delivering electricity over high-voltage power lines from the generation company to the distribution company, regulated by the Federal Energy Regulatory Commission (FERC). The Local Delivery part is regulated by the Public Utilities Regulatory Authority (PURA), and the Public Benefits part reflects costs incurred by electric companies for grid reliability, affordability, clean energy, and other energy policy directives.

Demand charges are based on the peak amounts of energy used in a given time period, known as demand intervals, and can be a significant portion of the total electricity bill. If you're on a demand charge electric rate, your bill will be based on the maximum amount of power you use over a single time period (like an hour or fifteen minutes) in a given month. You will still be billed for your monthly consumption, but the rate you owe for consumption will be lower compared to a typical bill.

Demand charges shift the focus from total consumption to the maximum power required over a single hour or fifteen-minute period in a month. This means that to reduce your bill, you need to decrease the amount of electricity you use all at once, rather than your overall usage. Demand charges have historically been used for industrial customers but are now appearing for residential customers.

Time-of-use electric rates are designed to incentivize reduced electricity usage when the cost of generation is high. These rates follow a set schedule, resulting in higher charges when the cost of generation and demand are high (e.g., the afternoon of a hot summer day) and lower charges when they are low (e.g., the middle of the night).

Solar systems can help reduce or eliminate electric bills, with the payback period for solar investment in Connecticut being around 8.83 years. However, with demand charges, the benefit of solar energy may be reduced as your peak energy consumption may not align with the peak output from your solar array.
