Texas / ERCOT example
How 4CP and 12CP can produce different exposure
This simplified example illustrates why a facility that manages four summer coincident peaks may still face greater transmission exposure under a year-round monthly structure.
Illustrative facility
10 MW operating load
Under 4CP, exposure is concentrated in four summer coincident-peak intervals. Under 12CP, exposure may reflect a monthly coincident peak in every month of the year.
Reduced load during the four summer coincident-peak intervals.
Higher average exposure across twelve monthly coincident-peak intervals.
Before any change in rates, rules, interval definitions, or operating constraints.
The example is illustrative only. Actual billing depends on the applicable TDSP tariff, final regulatory rules, meter data, billing-determinant definitions, and REP contract structure.
