What is Rate Switch Savings?

Rate Schedule Savings refers to the portion of electric bill savings in your proposal that comes specifically from switching to a different utility rate schedule. In ETB Developer, we separate this value from Solar PV and Battery ESS savings so it’s easy to see how much the rate change contributes on its own.

When Rate Switch Savings Are Shown

Rate switch savings appear when one of the following is true:

• A forced rate switch is configured in the design.

• Greatest Savings is enabled, and the greatest savings come from the New Rate Schedule.

If the Current Rate Schedule results in higher savings than the New Rate, then no rate switch savings will be shown.

How Rate Switch Savings Are Calculated

When applicable, rate switch savings are isolated from other savings types (like PV or ESS) to provide transparency into how much of the total savings are due to the rate change alone.

Formula: Charges Post PV (Current Rate Schedule) - Charges Post PV (New Rate Schedule)

This value reflects only the difference in charges resulting from the rate switch. 

Important Notes

• Rate switch savings are only shown when the New Rate Schedule results in greater savings than the Current Rate Schedule.

• These savings are separate from Solar PV and Battery ESS savings and help quantify the impact of the rate change alone.
