Maverick EnergyThe Illinois Commerce Commission has agreed with solar advocates that faulty math should not determine which residential solar customers in the state receive retail-rate net metering – the compensation residential solar owners receive for the surplus power they put back on the grid.
In a Dec. 2 decision, the commission rejected investor-owned utility Ameren Illinois’ calculation of a 5% threshold, which, the utility claimed, allowed it to switch new residential solar customers from retail-rate net metering to significantly lower “location-based distribution rebates.”
