500 KWh vs. 1000 KWh – How Can it Change Your Bill?
Here are two examples of electric energy use. The first example is for 500 kWh of energy used for the month.
- The electric bill amount is $81.47
The second example is for 1,000 kWh.
- The electric bill amount is $233.03
These examples are for a customer located in the Inland climate zone who receives basic service baseline allowances (receives energy from both an electric and natural gas), and the electric bill is based on a 30 day billing period for the summer season.
500 KWh Monthly Electric Usage Scenario
If 500 kWh of electricity was used for the month, only 13% of the monthly usage would be billed under the tier three rate, and no energy would be billed under the tier four rate.
By keeping most of the energy usage billed under the lower tier one (baseline) and two rates, the total amount of the monthly bill is lower.
| | Total Rate | KWh Used | Estimated Billed Amount |
Baseline | Tier 1 | 14¢ | 336 | $47.04 |
101% - 130%
of baseline | Tier 2 | 16¢ | 101 | $16.16 |
131% - 200%
of baseline | Tier 3 | 29¢ | 63 | $18.27 |
Over 200%
of baseline | Tier 4 | 31¢ | 0 | $0.00 |
| | | | 500 | $81.47 |
1000 KWh Monthly Electric Usage Scenario
If 1,000 kWh of electricity was used for the month, 56% of the energy usage would be billed under the tiers three and four rates.
Because the tiers three and four rates are significantly higher than the tier one (baseline) and two rates, the electric bill amount associated with tiers three and four usage is approximately 73% of the total electric bill.
| | Total Rate | KWh Used | Estimated Billed Amount |
Baseline | Tier 1 | 14¢ | 336 | $47.04 |
101% - 130%
of baseline | Tier 2 | 16¢ | 101 | $16.16 |
131% - 200%
of baseline | Tier 3 | 29¢ | 235 | $68.15 |
Over 200%
of baseline | Tier 4 | 31¢ | 328 | $101.68 |
| | | | 1000 | $233.03 |
This example is for a customer located in the Inland climate zone who receives basic service baseline allowances (receives energy from both an electric and natural gas), and the electric bill is based on a 30-day billing period for the summer season.
These examples are intended to be illustrative and use rounded total rates for SDG&E’s standard residential electric service, which includes rates under Schedule DR, Schedule EECC and Schedule DWR-BC, rounded to the nearest cents.
Your actual rates can be found on your bill. These examples excludes “Other Account Charges” as identified on your bill.
