4 CP Response Methodology
Analysis limited to ESIIDs in competitive ERCOT areas with ‘BUSIDRRQ’ profile types Transmission charges are based on ESIID-specific load during CP intervals ESIIDs classified by connection at transmission or distribution voltage level Distribution ESIIDs were classified based on weather sensitivity
Classified days as CP Days, Near-CP Days and Non-CP Days Near-CP days
Base-lined transmission total load for all summer weekdays using the 20 days nearest in time (before and after) excluding CP days and holidays Applied Day-of-Adjustment factor to baseline
Days with at least 100 MW reduction for Hour-ending 5:00 PM were classified as near CP days – found 69 Near-Peak days between 2009 - 2014
Non-CP days were all remaining non-holiday weekdays (June 1 – Sep 30)
Classified ESIIDs based on Weather Sensitivity and Load Factor Weather sensitivity (R2 for week-day use vs average temperature >= 0.6) Load Factor based on week-day afternoon usage (1:00 PM – 6:00 PM) High LF > 0.85 Medium LF > 0.60 Low LF ≤ 0.60

4 CP Response Type Classification
All ESIIDs subject to 4-CP charges were base-lined Non-weather sensitive: 20 Non-CP days clostest in time (before and after) Weather sensitive using regression baseline Day-of-adjustment factor from midnight to 3:00 PM was applied to baseline
Used baselines to calculate hour-ending 5:00 pm CP and Near-CP reductions (MW and percent) for three years closest to the analysis year (40 – 48 days of possible reductions)
Usually used the analysis year, the year before and the year after If the frequency and magnitude of MW17 reductions on CP and Near-CP days met
thresholds the ESIID was classified as 4-CP responder If not, just the analysis year and year after were examined
This was done to improve the classification of ESIIDs that started responding to 4-CP during the analysis year)
ESIIDs classified as responders were also examined for usage patterns indicating ‘day-use’ reduction for the 9:00 am – 4:00 pm time period on CP- and Near-CP days.
Based on the frequency and magnitude of ‘day-use’ reductions ESIIDs were classified as reducing or not reducing ‘day-use’ on CP- and Near-CP days.
4
Quantifying 4-CP and Near-CP Reductions
ESIIDs already classified as responders were used in the calculation for a day if they reduced by more than the lesser of 10% or the ESIID’s average reduction determined during the classification for the hour-ending 5:00 PM
ESIIDs with a lower reduction or ESIIDs already classified as non-responders were not part of the reduction calculation.
If the ESIID was classified as a peak responder, a scalar day-of-adjustment was applied to the baseline for calculating the load reduction for the CP/Near-CP day.
No scalar adjustment was applied to ESIIDs previously classified as having ‘day-use’ response.
The methodology was modified from last year to narrow in on response from responding ESIIDs and to more effectively remove the impact of non-responding ESIIDs from reduction calculations.

• Number of Near-CP days averaged about 10 per year
• Since 2009, no CP intervals have occurred prior to interval ending 4:00 pm
• Of the 24 CP intervals since 2009, only 5 appear to have been shifted by 4-CP response– 2 shifted one interval earlier– 2 shifted one interval later– 1 (7/16/2010) shifted one day earlier and one interval later
