Pacific Gas and Electric Company (PG&E) obtains a significant fraction of its electric energy and capacity from its own hydrogeneration facilities. Hydropower is very flexibility, but is constrained by energy limitations. Optimal scheduling of hydrogeneration, in coordination with other energy sources and streamflow forecasts, is a stochastic problem of great significance to PG&E. This paper describes the SOCRATES system for the optimal scheduling of hydropower generation over a one- to two-year horizon. Possible hydrologic inputs are described by an event tree and the resulting stochastic optimization problem is formulated as a network and solved using Benders decomposition. The network model includes a description of operations within each period. A streamflow forecasting model and data handling capabilities are important components of the system.
