Section 25 of the electricity act, 2003 authorises the central government to demarcate the country into regions necessary for the efficient, economical and integrated transmission and supply of electricity, and in particular to facilitate voluntary interconnections and co-ordination of facilities for the inter-State, regional and interregional generation and transmission of electricity. Electricity is listed in the concurrent list (entry 38 of list III). The traditional and unscientific demarcation of the country into five regions (north, south, east, west and north east regions) without giving any valid justification and applying one set of rules for intra region and different set of rules for inter regions in sharing electricity transmission system and transmission losses, etc. is considered discriminating one state from another state. Without the public interest, Constitution does not recognise different set of rules applicable for a group of states except ratified by each of the concerned state under of the constitution.
