Several challenges to generation capacity adequacy have been present in the ongoing deregulation electric power industry hindering stimulating capacity investment in generation capacity. Recently years, capacity mechanisms have been built up in order to steady the electricity market price and retrieve the electricity generation investment. These capacity mechanisms have achieved remarkable success, such as PJM´s capacity obligations in eastern America. These complementary capacity mechanisms ensure capacity adequacy, and their market clearing price will be reasonable for the electricity generating investment. In this paper, we analyse the capacity investment planning for the mix of generating technologies with an economic assessment concept. We present a contradistinctive result applied to study investor profit and electricity cost under capacity market and energy-only market. And it is of great significance that the appropriate electricity mechanism for capacity investment planning would appear in the course of the ongoing deregulation electric power industry.
