LPNJCTSS – GWF_HEP 115 kV (ckt 1) is a transmission line operating at 115 kVthat appears as a congestion constraint in the California ISO market. When power flow reaches this element's operating limit, CAISO's market optimization assigns it a shadow price — the cost to the system of that limit binding — which in turn drives locational price separation around it.
Across the market intervals retained in this dataset, it has bound 3 times, with the largest shadow price observed at $45.27/MWh on 2026-08-03. Prices are shown with the sign CAISO publishes; magnitude is the severity signal.
