Line_DSN-FH_69KV is an intertie scheduling constraintthat 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 23 times, with the largest shadow price observed at $981.04/MWh on 2026-08-05. Prices are shown with the sign CAISO publishes; magnitude is the severity signal.
