Adding solar panels and switching rate plans can lower your Dominion Energy South Carolina electric bill

Updated: October 22, 2020

There are three ways you can reduce your Dominion Energy 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. Dominion Energy 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 Dominion Energy South Carolina 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 Dominion Energy South Carolina each year for no reason.

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

Are solar panels worth it for Dominion Energy South Carolina customers?

Yes, with a strong South Carolina tax credit of 25% of your solar purchase and installation costs, solar panels for your home make a lot of sense for Dominion Energy South Carolina customers. Dominion's excess solar generation rate rider also allows you to get full credit on your power bill for the excess solar electricity your panels produce which you can’t use onsite. Your credits accrue at the same rate you pay for electricity, and roll over to the next month’s bill.

Does Dominion Energy South Carolina offer full 1 for 1 net metering credits for exported solar power

Yes, Dominion Energy South Carolina 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 Dominion Energy South Carolina, 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 $0.09 for power exported at off-peak times.

If you have excess energy credits after offsetting your usage over the course of a year, Dominion will pay you out for those credits at its "avoided cost" rate (based on the wholesale price of electrcity over the year). After that, the amount of excess energy in your account will be reset to zero and you can begin earning further credits for the next 12-month period.

What incentives, tax credits and rebates are available to Dominion Energy customers for installing solar?

The major financial incentive currently available until the end of 2020 is the 26% 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 Dominion Energy customer:
