During the weekday night hours, to satisfy the lowest load demand by a power generation system, the thermoelectric unit load following strategy may be managed with the hydro storage operation.

In this paper, a methodology, for the evaluation of fuel energy consumption of fossil fuel power generation system, with or without the hydro storage application, is presented, taking into account, particularly the spinning reserve presence.

It is shown that, when pumped storage power stations are considered, for the two homogeneous sets of fossil fuel power units (conventional and advanced) analyzed, an important role is played by the spinning reserve. Moreover, a considerable saving in daily fuel consumption is achievable in the case of advanced power units. It was also found that an increase in the thermoelectric load factor may reduce the hydro storage operation saving on the kWh variable cost.
