What Happens to Solar Power You Don’t Use

This entry was posted in Solar Services on by .

Once your home solar energy system is up and running, what happens to excess solar energy that you don’t use? The good news is that extra power is sent to the grid for everyone to use. Let’s look at how you can benefit from excess solar power and programs in place by APS and SRP.

Excess Energy Compensation

The Arizona Corporation Commission established the Resource Comparison Proxy (RCP) in 2018. The RCP compensates homeowners for excess power produced by home rooftop solar systems. Without getting too detailed, the RCP is based on average open market costs over a recent five-year period. There are rules in place to not allow the annual excess power rate to decrease by more than 10%. You’re compensated for up to 10 years at the rate set during interconnection with the power grid. This is advantageous to you since solar power prices have fallen over time. The current RCP rate of $.0781 per kWh continues until September 30, 2022.

APS Programs

APS’s program is called RCP Export Rider. APS measures the extra power your family doesn’t need and credits your next monthly bill using the current net billing solar purchase energy price. APS installs an AMI meter which can remotely collect solar usage in real time.

SRP Programs

SRP installs a second power meter at your home to monitor the daily energy output from your solar panel system. This data is used for SRPs two excess solar energy programs.

Renewable Net Metering Rider

SRP automatically enrolls customers in this program unless you choose to enroll in the Buyback Service Rider. Excess energy generated is rolled over to the next month. Any energy rolled over and not used after 12 months is credited back to your account at the current RCP rate.

Buyback Service Rider

When the power produced by your solar array system is greater than the energy needs of your home in a particular hour, the excess power is credited to your utility bill. SRP determines the energy credit by using the hourly indexed kWh price less SRP’s costs for scheduling, dispatch services, and system control.
