United Illuminating Company Electricity Prices & Plans

Shopping for electricity in Connecticut, because it is deregulated, is no different than now people shop for internet, cell phone plans, car insurance or cable. They have options, and they want to do it online because that's the easiest way to shop! In Connecticut, the two main differentiators in electricity plans are the rate and the number of Billing Cycles. This can be as low as a few months or as long as a few years.

Fixed Electricity Plans & Rates
Customers in the United Illuminating footprint in Connecticut will have the ability to pay the same rate for electricity each month with a Fixed Rate Electricity Plan. Basically, just like a cellular phone plan, you're paying the same rate for the electricity each month (Billing Cycle) and the variable on how much your bill will be is the amount of electricity that you use. Naturally in CT this will fluctuate depending on the time of the year, but it still makes your monthly bills predictable. That being said, other things that could be add-ons to your bills could include any enrollment fees, cancellation fees, or monthly service charges.

Explaining United Illuminating Delivery Charges.

There are two main areas that electricity service in Connecticut can be carved. First is generation supply, or effectively the electricity rate. The Public Utilities Regulatory Authority (PURA) approves the standard service generation rate, and you can also choose an alternative supplier for electricity and select their rate. The second area would be delivery. United Illuminating Company maints the power lines, poles, wires and all the infrastructure to reliably make sure electricity gets from point A to point B when you turn something on in your home, customers will also pay a delivery charge to cover operating costs. This delivery charge is overseen by PURA as well.

Generation Services Charges for United Illuminating

Customers can select an electricity rate from a competitive supplier, or from a standardized rate from United Illuminating Company.

A wholesale auction determines the supply rate for UI. PURA then approves the rate. This rate is then offered to customers without any markup. This happens twice a year, which means UI??™s rate changes every six months, on January 1st and July 1st. Competitive rates can end up lower than the UI rate if they create market efficiencies and can offer customers a lower rate than the incumbent utility.
