1/ "Wheeling Received" and "Wheeling Delivered" for ERCOT in 1997, 1998, 1999, and 2000 reflect enactment by the Public Utility Commission of Texas (the Commission) of Substantive Rule 23.67 ("Open-access Comparable Transmission Service"), effective on September 12, 1996. SR 23.67 governs virtually all phases of transmission access in Texas and requires that wheeling services, provided by transmission facility operators under the jurisdiction of the Commission, shall be reimbursed using the vector-absolute, megawatt/mile method. This method derives reimbursement rates utilizing information on the total line-mileage under load, the maximum load in megawatts, and the fee per megawatt-mile. Use of this method does not require transmission service providers to measure energy flows.
Notes: · Data are final. · In 1998 several utilities realigned from SPP to SERC. · On January 1, 1997, FRCC became the tenth NERC region, separating from SERC. · Totals may not equal sum of components because of independent rounding. · This is a summation of utility trade for utilities that operate within the NERC Region. · Due to the complexity of electric power transactions that involve specifics of contracts, simultaneous energy transactions, the unintended receipt and delivery of energy (inadvertent flow), and losses, uniformity in reporting the classification and quantity of each transaction among utilities may not exist. · Includes utility, export, and nonutility transactions.
