Beginning in 1996, with the? Federal Energy Regulatory Commissionâ??s (FERC) orders 888 and 889,? the electric power industry began the task of unbundling? generation of electricity from transmission, and Independent System Operators were created to manage the operation of the transmission grid? to provide equal access to all generation facilities and power producers. At the same time an Open Access Same-Time Information System (OASIS) was created to help with the management and reservation of transmission facilities to accommodate energy transactions across the north American interconnected transmission system. Soon it became apparent that the resulting increase in energy transactions was exercising the transmission facilities in way not seen before, with the Control Area operators observing congestion in their transmission systems without knowing the source or the cause. The main problem arose from the fact that transmission reservations were made based on agreed upon â??Contract Paths??? which had little or no correlation with the flow of power on â??Physical Pathsâ?? as dictated by the laws of physics.
To deal with this problem, and electronic tagging, or e-tagging, system was designed and implemented to provide Control Area operators with information on all energy transactions that flowed through their systems. In addition, an Interchange Distribution Calculation (IDC) system was developed to calculate the physical impact of individual transaction on the power grid and transmission equipment for use in support of Transmission Loading Relief (TLR) procedures that were developed to mitigate congestion in? transmission systems.
Over the years e-tagging has evolved to serve as a mechanism for the capture and the management of all data related to energy transactions not only to support congestion management but also to support tracking and management of Renewable Portfolio Standard (RPS) and for Greenhouse? Gas (GHG) emission monitoring and tracking, among other things.
