Adding solar panels and switching rate plans can lower your United Illuminating Company electric bill
Updated: October 22, 2020There are three ways you can reduce your UI bill: changing your habits, switching your rate plan, and adding solar panels.
You've probably heard a lot about reducing energy consumption by doing things like switching to LED lightbulbs and adding insulation to your walls, but these fixes are relatively easy compared to the far more impactful step of making changes to your lifestyle.
The second thing you can do is switch your rate plan. UI offers time-of-use billing that can help you save money by shifting your usage of energy-intensive appliances to off-peak hours, and there may be other options for you as well.
Finally, you can reduce or even eliminate your electricity bill by installing solar panels on your home.

How much can I reduce my United Illuminating Company bill by switching to a different rate plan
For some people, the savings from switching rate plans may only be a few dollars per month, but for many it can be $20-$100 per month. That's between $240 and $1,200 that you may now be paying to United Illuminating Company each year for no reason.
Finding out what's available to you is as simple as a phone call or email to United Illuminating Company. Even a small savings can be worth it.
Are solar panels worth it for United Illuminating Company customers?
Absolutely, yes! With a hefty $426 per kilowatt solar rebate, available low income solar program, and sales and property tax exemptions, solar panels make a lot of sense for United Illuminating Company customers in Connecticut. UIC net metering also ensures you get credited on your power bill at full retail rates for the excess solar electricity your panels produce. Your credits are rolled over and applied to your next month’s bill.
Does United Illuminating Company offer full 1 for 1 net metering credits for exported solar power
Yes, United Illuminating Company offers 1 for 1 net metering. This means you are paid the same rate for excess solar energy that you export to the utility grid during the middle of the day as what you pay for power purchased from the grid.
In the case of United Illuminating Company, Time of Use (TOU) pricing applies. You will earn an average of $0.38 for power exported at peak rate times, and an average of $0.17 for power exported at off-peak times.
If you have excess energy credits after offsetting your usage over the course of a year, UI will pay you out for those credits at a special rate per kWh calculated based on its wholesale energy cost over the year. After that, the amount of excess energy in your account will be reset to zero.
What incentives, tax credits and rebates are available to UI customers for installing solar?
The major financial incentive currently available until the end of 2023 is the 30% federal solar tax credit. The way this works is that the full cost of the system needs to be paid to the installer, and this tax credit can then be claimed back as cash when you next do your taxes.
Many states, local governments and utilities also offer incentives for homeowners who go solar. This help can take the form of state tax credits, rebates, tax breaks, SRECs or even performance-based incentives. The best part is that all of these incentives apply in addition to the federal credit.
Here is every incentive you may be eligible for as a UI customer:
