Appraisal of Centralised and Decentralised Energy System

Abstract

Grid system based on centralised electricity generation has posed serious challenges to the environment as well as to the economy.  These systems have failed to electrify every household in the country due to technical and economical non-feasibility apart from higher transmission and distribution losses. In this context, distributed generation (DG) have been playing a prominent role in the regional development as well as electrification of remote villages. DG optimally harvests locally available renewable energy sources and integrates with the grid. Regional Integrated Energy Plan (RIEP) based on decentralised energy systems optimises share of available resources while ensuring reliable energy supply. Spatial assessment of renewable energy sources aids in effective planning to meet the energy demand at local levels. An optimal energy plan based on renewable energy sources mitigate GHG emissions, while providing reliable energy to all citizens in India.
