§ 1344. Load Metering Reports.
(a) Annual LSE Customer Load Data by Hour. Beginning March 15, 2008, and every year thereafter, each LSE that has experienced a peak electricity demand of 200 megawatts or more in both of the two calendar years preceding the filing date shall submit annual load data, including losses, for every hour of the previous calendar year for its customers to which it provides generation services, separated by UDC service area in accordance with the following:
(1) Hourly load data and analyses shall be developed and compiled from actual load metering, or using valid statistical estimating techniques when actual measurements are infeasible;
(2) Load metering shall be conducted in an accurate and reliable manner;
(3) Hourly load data shall be delivered to the Commission in electronic form;
(b) Annual Distribution System Load Data by Hour. Beginning March 15, 2008, and every year thereafter, each UDC that has experienced a peak electricity demand of 200 megawatts or more in both of the two calendar years preceding the filing date shall submit its annual distribution system load data for every hour of the previous calendar year in accordance with the following:
(1) Hourly system load data and analyses shall be developed and compiled from actual load metering or from valid statistical estimating techniques when actual measurements are infeasible;
(2) Load metering shall be conducted in an accurate and reliable manner;
(3) Hourly system load data shall be delivered to the Commission in electronic form;
(4) Hourly loads shall be submitted in two formats: (1) the composite of the hourly loads (the composite of customer loads plus distribution losses) for all LSEs supplying electricity in the UDC's distribution service area, and (2) format (1) expanded to include hourly transmission losses for each hour.
(c) Hourly Load Estimates by Customer Sector. Beginning September 1, 2007, and every year thereafter, each UDC that has experienced a peak electricity demand of 1000 megawatts or more in both of the two calendar years preceding the filing date shall submit its hourly sector load estimates by customer sector for the previous calendar year in accordance with the following:
(1) The hourly sector load estimates shall, at a minimum, include identification of each of the following components:
(A) residential customer sector;
(B) commercial customer sector (including commercial building customer sector and other commercial customer sector);
(C) industry customer sector and other industry customer sector);
(D) agriculture customer sector;
(E) water pumping customer sector;
(F) street lighting customer sector;
(G) unclassified customer sector; and
(H) losses.
(2) The samples used to develop hourly load estimates for each sector shall be designed to insure that estimates are accurate to within ±10 percent of the monthly sector load coincident with system peak, and with 90 percent confidence.
(3) The hourly sector load estimates shall be delivered to the Commission in electronic form.
(d) Monthly Distribution System Load Data by Hour. Beginning March 15, 2008, and every month thereafter, each UDC that has experienced a peak electricity demand of 2000 megawatts or more in both of the two calendar years preceding the filing date shall submit its distribution system load data for every hour of the previous month in accordance with the following:
(1) Hourly system load data and analyses shall be developed and compiled from actual load metering or from valid statistical estimating techniques when actual measurements are infeasible;
(2) Load metering shall be conducted in an accurate and reliable manner;
(3) Hourly system load data shall be delivered to the Commission in electronic form;
(4) Hourly loads shall include all distribution and transmission system losses.
(e) Annual Electric Transmission System Peak Load Data by hour and subarea. Beginning June 1, 2008, and every year thereafter, each Electric Transmission System Owner that has experienced a peak electricity demand of 2000 megawatts or more in both of the two calendar years immediately preceding the filing date shall submit its hourly load data by subarea for every hour of the previous calendar year in accordance with the following:
(1) Hourly load data and analyses shall be developed and compiled from actual load metering or from valid statistical estimating techniques when actual measurements are infeasible;
(2) Load metering shall be conducted in an accurate and reliable manner;
(3) Hourly load data shall be delivered to the Commission in electronic form;
(4) An electronic file containing geographic identifiers of the subarea shall be included;
(5) Subareas are climate zones or geographic subdivisions of the transmission system area used by the transmission system owner for transmission system expansion plan studies, including studies of local deliverability of load, prepared for the control area operator or governing body.
(f) Emerging Load Impacts. On August 1, 2019 and March 15 every year thereafter, each UDC that has experienced a peak electricity demand of 1000 megawatts or more in both of the two calendar years preceding the filing shall provide a summary of load research data used by the UDC during the previous calendar year for characterizing, assessing, and forecasting load impacts associated with any of the following:
(1) Photovoltaic generation;
(2) Plug-in electric vehicle charging; and
(3) Energy storage system operation.
