Power generation plan developing apparatus, power generation plan developing method, and recording medium

In one embodiment, a power generation plan developing apparatus includes a power generation information processor to process information on performances or a group of power generating facilities, the processor predicting the performances based on data on a natural environment, or registering data on the facilities belonging to the group and data on a limitation on the group, as a definition of the group. The apparatus further includes a power generation plan creator to create a power generation plan about the facilities based on the performances or definition. The creator creates first and second plans based on the performances predicted from first and second data on the natural environment to create a third plan, or selects at least any of load dispatching about first and second groups to which the facilities having first and second performances belong, to create the power generation plan based on the selected load dispatching.
