Adding solar panels and switching rate plans can lower your Eversource Energy Connecticut electric bill

Updated: October 22, 2020

There are three ways you can reduce your Eversource CT 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. Eversource CT 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 Eversource Energy Connecticut bill by switching to a different rate plan

Finding out what's available to you is as simple as a phone call or email to Eversource Energy Connecticut. Even a small savings can be worth it.

Are solar panels worth it for Eversource Energy Connecticut 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 Eversource Energy customers in Connecticut. Eversource net metering policy 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 Eversource Energy Connecticut offer full 1 for 1 net metering credits for exported solar power

Yes, Eversource Energy Connecticut 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 Eversource Energy Connecticut, Time of Use (TOU) pricing applies. You will earn an average of $0.27 for power exported at peak rate times, and an average of $0.16 for power exported at off-peak times.

What incentives, tax credits and rebates are available to Eversource CT 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 Eversource CT customer:

Upfront Incentives Value*
Residential Clean Energy Tax Credit (Federal) -$8,303

Customers choose between a "buy all" program under which all their solar energy will be purchased by the utility company for a set rate, or a monthly netting program, under which their excess solar energy would be counted by the utility as on-bill credits, plus a potential payment for RECs to ensure the intended rate of return.

Sales and Use Tax Exemption for Solar and Geothermal Systems (State)

Solar energy equipment is exempt from 100% of state sales tax.

Property tax Exemption for Renewable Energy Systems (State)
