Adding solar panels and switching rate plans can lower your Portland General Electric electric bill

Updated: October 22, 2020

There are three ways you can reduce your PGE 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. PGE 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 Portland General Electric 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 Portland General Electric each year for no reason.

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

Are solar panels worth it for Portland General Electric customers?

Yes! With Energy Trust of Oregon solar rebates, the Solar Within Reach low income incentive program, and a solar property tax exemption, home solar panels make a lot of sense for Portland General Electric customers in Oregon. PGE’s net metering rate 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 as retail rates, and roll over to your next monthly bill.

Does Portland General Electric offer full 1 for 1 net metering credits for exported solar power

Yes, Portland General Electric 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 Portland General Electric, Time of Use (TOU) pricing applies. You will earn an average of $0.12 for power exported at peak rate times, and an average of $0.04 for power exported at off-peak times.

Any remaining unused kilowatt-hour credit accumulated over the year will be transferred to PGE's low-income assistance program. That's a laudable policy piece from Salem we'd like to see other state governments across the country enact.

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

Table 1: Incentives
Upfront Incentives Value*
Residential Clean Energy Tax Credit (Federal) -$8,761
Oregon Solar + Storage Rebate Program (State)

$0.50 per watt installed up to $5000 or 40% of the system costs, whichever is cheaper. This is for non-income restricted households. Households with lower incomes are eligible for a higher rebate. Households that are not income-restricted and take advantage of other utility incentives receive a lower rate. Additional incentive of $300/kWh of battery storage installed up to $2,500. Details in this blog post;

Net Metering (State)

Investor-owned utilities must credit excess generation as kWh credits that get carried over to the next bill. At the end of the billing cycle, customers are compensated for excess credits at the avoided cost rate. Municipal utilities/cooperatives can bill as kWh credits or at avoided cost rate.

Property Tax Exemption for Renewable Energy Systems (State)

100% of solar system cost is exempt from property taxes.

Energy Trust of Oregon Incentive - Portland General Electric (Utility)

Energy Trust Incentives available via Portland General Electric and Pacific Power.

Solar Within Reach (Utility)

$1,400 per kW of installed solar for customers of Portland General Electric, and $700/kW for customers of Pacific Power. Incentive program administered by Energy Trust of Oregon. Eligibility depends on household incomes; a family of 4 with an income under $106,944 qualifies in 2022.
