Read BPA hydropower, transmission and interchange
Bonneville Power Administration operates a balancing area and markets federal hydroelectric power in the Pacific Northwest. It does not operate an ISO or RTO nodal market of its own. Market prices at its locations retain the identity of the market that published them.
Read BPA demand and generation alongside reservoir observations, dam operations and published transmission-path flows. Compare flow with the corresponding path limit and time; a river observation and a market price are separate measurements.
Open the Northwest map to inspect dams, transmission lines, substations and published interconnection requests. The agent can investigate those records with the source and observation time attached.
