Commercial/General Service Rate Design Changes

In addition to biennial increases to the facilities charge and corresponding offsetting reductions in the kilowatt-hour charge, this rate class also sees adjustments to demand charges, which measure peak energy use within a given month. This rate class accounted for slightly more than 8 percent of all membership accounts at the end of 2018.  Kilowatt-hour rate projections include no assumptions about inflation or future Bonneville Power Administration rate increases.
