When the duration curve method is
remote areas, power-duration curves
(or for groups of months with similar
loads), and the curves can be adjusted manually to reflect usable
energy (Figure 5-14). The same approach could also be used with the
hybrid method. Alternatively, maximum usable generation values could
be specified for each month and the model could be set to
automatically limit generation to these values.
(5) The primary source of generation requirements for energy
studies should be the regional Power Marketing Administration (Pm)
responsible for marketing the power from the proposed hydro project.
However, in some cases, the PMA?s generation requirements reflect
contractual constraints which would preclude developing an operating
plan which maximizes NED benefits. Where this occurs, two separate
plans should be developed: one which maximizes NED benefits, and one
which meets the PMts requirements, Both should be considered in the
selection of the recommended plan. Sources of generation data are
discussed in Section 3-5.
