Traditionally the reliability index for generation planning has been used 0.7[days/year] in LOLP in this country. However, it seems to be time that the index should be reexamined as the scale of the power system has been grown remarkably during past decades.
Reliability expression by LOLP may not be enough since it lacks information of such as severity of supply shortage. It can be complemented by other indexes, but these are not widely used due to their complication.
This paper presents a result how supply shortage costs influence reserve levels of generation planning and that the appropriate level has been tried to be determined from those influences. New reliability index is suggested.
