For a California utility, we developed and ran a PSO model of the entire Western Electricity Coordinating Council (WECC) to capture the expected congestion patterns within the California Independent System Operator (CAISO) for the next year. We provided scenario analysis on high and low gas prices, high and low hydro conditions, and high and low load forecasts to capture possible deviations from the expected market conditions. Our final recommendations to the client were on congestion revenue rights positions to buy to hedge against congestion risk in the market.
