There used to be only those areas (villages/hamlets) where grid extension is not viable for techno-economic reasons, in the Decentralized Distributed Generation (DDG) mode of RGGVY scheme (now DDUGJY) of Rural Electrification in India. However the Government of India has included, in 2013, villages that get less than 6 hrs of electricity in Decentralized Distributed Generation (DDG). How to identify those villages? Any public forums available to access such data?
