Adding solar panels and switching rate plans can lower your Idaho Power Company electric bill

Updated: October 22, 2020

There are three ways you can reduce your IPC 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. IPC 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 Idaho Power 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 Idaho Power Company each year for no reason.

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

Are solar panels worth it for Idaho Power Company customers?

Perhaps. With a personal income tax deduction for solar which can save you about $1,100 over four years on an average sized system, and Idaho Power’s net metering program still intact, home solar panels are an investment worthy of your consideration. Idaho Power’s excess solar generation rate rider 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 Idaho Power Company offer full 1 for 1 net metering credits for exported solar power

Yes, Idaho Power 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 Idaho Power Company, Time of Use (TOU) pricing applies. You will earn an average of $0.13 for power exported at peak rate times, and an average of $0.07 for power exported at off-peak times.

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

Table 1: Incentives
Upfront Incentives Value*
Residential Clean Energy Tax Credit (Federal) -$9,102
Residential Alternative Energy State Tax Deduction (claimed over 4 years) (State)

For the year a system is installed, homeowner can claim a tax deduction equal to 40% of the system's installation costs, up to $5,000. For the next three years, 20% of the system costs, up to $5,000, can be claimed. At Idaho's current tax rate of 6.5%, this represents a total possible tax credit of $1,300 ($325 for each of 4 years, on a system that costs at least $25,000).

State Energy Loan Program (State)

Low interest Loans for Renewable Energy projects ranging from $1,00 to $15,000 for single family loans

Idaho Power - Net Metering (Utility)

Net excess generation is credited at the retail rate. Credits expire at the end of the billing cycle.

TOTAL -$10,402

*Based on 14.36 kW system, average installation cost $31,638
