This calculator shows you an estimate of your baseline allowance and how your electric usage is divided among the four rate tiers. Have your SDG&E bill handy, because there is information on your bill you will need for the calculator.
What are the factors affecting your baseline?
Every customer is allotted a daily baseline allowance. Month-to-month your baseline allowance can change due to differences in the number of days in your billing cycle. Your daily baseline allowance is determined by the following:
SDG&E’s service territory is divided into four different climate zones: (1) Coastal, (2) Inland, (3) Mountain, and (4) Desert. Each climate zone is assigned different daily baseline allowances.
Please see below for climate zone map.
The daily baseline allowance varies by season. For residential customers, the summer season is defined as May 1 through October 31 and the winter season is defined as November 1 through April 30.
Customers that receive both electric and natural gas service, will have different baseline allowances (basic service baseline allowances) than customers with all electric service (all electric baseline allowances).
You can experiment with the calculator by changing the factors that affect the costs you pay for electricity usage. You will see how these changes affect the baseline allowance number and subsequent energy use (which is divided up into percentages of your baseline allowance or tiered usage.)
A change in season (summer and winter) will affect results for the months of May and October because part of your energy usage may cross over into both seasons.
