A mathematical programing model which has a nonlinear objective function and linear constraints is developed for the planning of composite regional water‐energy systems and is solved using the largescale generalized reduced‐gradient technique. Three interacting subsystems (the water subsystem, the power generation subsystem, and the coal and synthetic natural gas subsystem) are modeled to define the interlinked water‐energy system. The objective of the model is to minimize the sum of the capital, operating, and distribution costs incurred in meeting future water, gas, coal and power demands within a region. The nonlinear objective function represents an improvement over existing models, as it permits analysis of nonlinear system response and economies of scale. The model is applied to a region located in northeastern Texas.
