Rate 37 Online Calculator
Rate 37 is a time-of-day rate available for general service customers with annual maximum demands less than 350 kW.
Beginning January 1, 2009 customers whose peak demand is between 300 kW and 350 kW* are required to take service under Rate 37.
The following calculator will help you understand the impact of billing under Rate 37, and of how shifting your electricity usage will affect your bill.
