Connecticut electricity rates are deregulated allowing residents to shop for an alternate energy supplier and save money on the electric bill. Thanks to legislation known in Connecticut as PA 98-28, the responsibilities of the utility companies became unbundled, opening the door to energy suppliers that now have to compete to earn the customer’s business. Allowing energy suppliers to compete has helped push down energy prices in the state and created more options for customers when it comes to choosing an energy plan.

Connecticut Standard Offer Service

The utility companies in Connecticut are required to act as the default supplier for customers who do not change energy companies. The supply rate charged by the utility companies is known as the Standard Offer Service (SOS). The SOS changes twice per year and is not considered a long-term fixed rate. This rate is often referred to as the price to compare. Connecticut residents shopping for an electric supplier will use the price to compare while comparing energy plans. If a supplier is offering a supply rate lower than the price to compare then the customer will be saving money by switching.

Connecticut Utility Companies

Eversource Energy formerly known as Connecticut Light and Power and The United Illuminating Company are two investor-owned electric distribution companies (LDC) that operate in the state of Connecticut. The Public Utilities Regulatory Authority of Connecticut (PURA) is responsible for regulating the rates and services for these two utility companies. Connecticut residents living in either utility area are free to shop for a competing energy supplier.

Protect Your Home From Power Outages With The United Illuminating Shield&Connect Plan

Connecticut is no stranger to severe weather. In 2013, a powerful blizzard rolled through the state knocking out power to tens of thousands of residents. The storm brought the state to a complete standstill. If you have ever lived in a place that has experienced a pro-long power outage you can understand how frustrating it can be. Now you can protect yourself and your family with The United Illuminating Shield&Connect Plan.

The Shield&Connect Plan protects your home by minimizing any power surges that may occur. Depending on the plan selected, you may also receive a power generator to protect against pro-long outages so you can maintain your standard of living. The plan comes in three packages; basic, premium, and ultimate.

Starting at $3.75 per month, protect your home appliances with the internal and external power surge protection plan. This package includes 6 surge suppressors along with a circuit tester. The plan helps divert power surges away from your home, protecting expensive plugin devices you may have.

Upgrade to the Premium plan starting at $8 per month and receive a portable generator that includes a plug-and-play connection installed right behind your meter box. The United Illuminating will be responsible for the installation process. This plan does not include the 6 surge suppressors received in the Basic.

At $9 per month, receive both the benefits of the Basic and Premium plans. This plan gives maximum protection so you can face Connecticut’s harsh winters knowing any power outage will not disrupt your standard of living.

Connecticut Implements a Renewable Portfolio Standard

Connecticut’s Renewable Portfolio Standard (RPS) is a state policy requiring energy suppliers to produce a specific percentage of power generated or sold from renewable energy resources. This policy creates a market for companies to get involved in renewable energy projects that otherwise would not have existed without state intervention.

The companies involved in renewable energy projects will receive a renewable energy certificate (REC) for every megawatt-hour (MWh) of electricity produced. RECs can be traded on the market and purchased by energy suppliers to meet the RPS requirements.  Connecticut RPS classifies renewable energy into one of three classes. Each class is defined by §16-1(a)(20) of the General Statutes of Connecticut which separates the energy by the source, it was derived.  

Classification Power Source
Class I
  • Solar power, wind power, fuel cell, geothermal, landfill methane gas, ocean thermal power, wave or tidal power
Class II
  • A trash-to-energy facility that has obtained a permit under section 22a-208a and section 22a-174-33 of the regulations of Connecticut state agencies
Class III
  • Electricity output from combined heat and power systems with an operating efficiency level of no less than 50% that are part of customer-side distributed resources developed at commercial and industrial facilities in Connecticut on or after January 1, 2006
  • Waste heat recovery system installed on or after April 1, 2007, that produces electrical or thermal energy by capturing preexisting waste heat or pressure from industrial or commercial processes
  • Electricity savings created in Connecticut from conservation and load management programs begun on or after January 1, 2006

Electricity Generation in Connecticut

As of 2018, over 90% of electricity generated in the state of Connecticut comes from natural gas and nuclear power. Natural gas alone accounts for half of the state’s net generation while other methods such as coal make up just over 10%. However, coal-fired generation is expected to fade out as the state’s last remaining plant is scheduled to close in 2021. Biomass, along with other methods of renewable energy generation is expected to increase per the RPS requirements.

Whether you are a customer of Eversource or United Illuminating, energy choice has opened up the market to energy suppliers allowing customers the opportunity to pay a lower generation rate on their electric bill. PURA provides a full list of electricity aggregators and suppliers that are licensed with the state to provide energy services to residential and commercial customers.
