Investigations of Capacity Expansion Planning Using LEAP Model

Abstract

Electrical energy is an essential and integral part of human life. The use of electrical energy is increasing day by day and therefore it is important to plan a future power system well in advance to meet the expected demand growth with a reasonable reliability level at minimum cost. Nowadays, renewable power generation plays an important role in power generation since, it is pollution free and zero fuel cost. In this paper an effort is made to project a future power system for Assam, an Indian state. In the present power systems, the electricity is generated mainly from non-renewable energy sources which increase greenhouse gases (GHG) emission and hence global warming. Keeping in mind about pollution impacts, renewable energy sources like wind, solar, biomass for the planning a future power system of Assam using long range energy alternative planning system (LEAP) software is considered. The proposed capacity expansion is planned for next twelve years from 2019 to 2030. In this work, the various scenarios developed separately with LEAP are Greenhouse gas mitigation scenario, Low demand growth and High demand growth scenarios. In addition to these, reference scenario has also been considered. In all these scenarios the system installed capacity and one-hundred-year global warming potential have been investigated quantitatively.
