Adding solar panels and switching rate plans can lower your Rocky Mountain Power electric bill

Updated: October 21, 2020

There are three ways you can reduce your RMP Utah 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. RMP Utah 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 Rocky Mountain Power 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 Rocky Mountain Power each year for no reason.

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

Are solar panels worth it for Rocky Mountain Power customers?

Probably. With a $1,600 solar tax credit and the available Federal 26% tax credit, home solar panels are worth your consideration as a Rocky Mountain Power customer in Utah. RMP’s "net metering transition" rate also ensures you at least get some credit on your power bill for the excess solar electricity your panels produce. Your credits, while accruing at a lower rate than you pay for electricity, are rolled over and applied to your next month’s bill.

Does Rocky Mountain Power offer full 1 for 1 net metering credits for exported solar power

RMP Utah does not offer net metering, but is instead transitioning to a program that pays a lower compensation rate for excess energy produce by solar panels. Helpfully, the Utah government has created a website with the latest information about the program.

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

Table 1: Incentives
Upfront Incentives Value*
Residential Renewable Energy Tax Credit (Federal) -$5,755
Net Billing (State)

Energy usage is netted at 15 minute intervals. Any excess generation within a 15 minute interval will be credited at rates established by Utah law. Any net excess generation at the end of a billing period will expire with no compensation.

In 2019 the previous tax credit of $2000 was due to end, however in March 2019 the credit was changed to $1600 and extended for an additional 2 years through to 2021. After that point the credit will gradually reduce until it is eliminated at the end of 2023.
