Hawaiian Electric has changed the rate programs offered to its customers over the last 10 years (NEM, CGS, Smart Export, CGS+, NEM+, etc.). Each program has a different impact on the calculation of your monthly electricity bill, so it is important to understand so that you can plan your monthly home ownership expenses accordingly.
