Oncor Electric Delivery Company (Oncor) successfully demonstrated a fully integrated dynamic line rating (DLR) system in its project funded under the U.S. Department of Energy's (DOEs) Smart Grid Demonstration Program (SGDP). The DLR system monitored the real-time capacities of eight transmission lines for use in the daily operations and wholesale electricity market of both the transmission owner and the independent system operator, the Electric Reliability Council of Texas (ERCOT). Oncor demonstrated that the increased grid capacity available from DLR technologies can be practically and automatically applied on a commercial basis. This breakthrough brings the theoretical benefits of DLR into the real world, demonstrating increased reliability, reduced cost of electricity, and improved access to renewable energy. The projects results confirm the high potential and commercial readiness of DLR systems.
