The economic value of hydropower is set equal to (or replaced by) a linear function of hydropower generated. The function can vary by time period. This method, in essence, models a block valuation but with only one block.

The constraint is written as an inequality rather than an equality to allow for piecewise linearization of power. This constraint is triggered by writing an objective function that includes maximizing Linear Avoided Operating Cost.
