Net Billing

Press Enter to show all options, press Tab go to next option

In order to ensure fair billing practices for all customers, IID adopted a new Net Billing Program in July 2016. The program brings prices in alignment with the real costs of providing power for all customers, including for those who choose to install rooftop solar systems on their homes.

The new program was a necessary solution that sought to balance the interests of all customers and will allow IID to continue to deliver on its obligation of providing the greatest value at the lowest cost. The new plan also eliminates a cap on participation levels, maintaining rooftop solar as an option for any customer who wishes to adopt it. 


Each billing month, IID will measure the energy delivered and received after your solar system serves your instantaneous load. You will receive a bill for the electricity you use according to your regular rate schedule. When your solar system generation is greater than your load, the district will pay for that energy at the same rate IID pays for energy from solar contractors.

Excess generation will be paid per the Distributive Self-Generation Service Rate Schedule, currently at 6.98¢ per kWh. This is a variable rate based on IID’s lowest wholesale solar contract cost at which IID’s procures solar generation. As determined by the district, the rate shall be adjusted as needed and made available effective immediately.
