Fixed Charges • A fixed charge - also known as a “customer charge” – is typically a flat monthly fee on a customer’s bill. • Fixed charges may also be tiered (different fee based on usage bracket) or a flat fee per day. • Fixed charges can typically not be offset by net metering credits.

Fixed Charge Trends • Not seeing a slowdown in utility requests to increase fixed charges • Very few utilities are being granted their full increase – even split between no increase & partial increase • Those being granted only a partial increase are getting, on average, about 60% of their requested increase
Demand Charges • A demand charge is typically a monthly charge based on a customer’s maximum demand in kW during the billing period. • Demand charges are typically based on a customer’s non-coincident peak demand, but may be designed to be based on coincident peak demand. • Like fixed charges, demand charges cannot typically be offset by net metering credits.
