Data Aggregation

This section contains daily data aggregation reports, including unaccounted for energy (UFE) reporting.

Also find transmission/distribution service provider (TDSP) distribution and transmission loss factors; and reports on peak demand for June, July, August and September (four coincident peaks).

Interval data recorder (IDR) and non-IDR load estimation and reports on compliance for IDR consumption data loading are also available.

Current Information

Actual Distribution Loss Factors Report
Deemed actual distribution loss factors used in the ERCOT settlement process which are calculated from the distribution loss coefficients submitted by DSPs and the ERCOT actual load.
Actual Transmission Loss Factors Report
Deemed actual transmission loss factors used in the ERCOT settlement process which are calculated based upon a linear interpolation or extrapolation using the on-peak and off-peak TLFs corresponding to the actual ERCOT system load.
Confidentiality Expired Adjusted Meter Load Report
View the AML for each QSE by LSE, by Load Zone and by Settlement Interval, both from the initial settlement and all subsequent settlements, 180 days after the Operating Day.
Forecasted Distribution Loss Factors Report
Deemed forecasted distribution loss factors which are calculated from the distribution loss coefficients submitted by DSPs and the ERCOT forecasted load.
Forecasted Transmission Loss Factors Report
Deemed forecasted transmission loss factors which are calculated based upon a linear interpolation or extrapolation using the on-peak and off-peak TLFs corresponding to the forecasted ERCOT system load.
IDR Protocol Compliance Report
This report displays a Protocol Compliance percentage (%) value for each MRE and the MARKET for the minimum RTM True-Up trade date scheduled for settlement plus the next 29 consecutive RTM True-Up trade dates.
IDR Protocol Compliance Verification for Disputes
This report provides the number of active IDR ESIIDs for a specified time period and determines the percentages of actual data for a specific dispute date.
Load Estimation Counts
Counts of ESIIDs and percentages of counts by MRE settled with actual meter data, estimated using historical meter data, and estimated using default load.
