|Orissa is the first State in the Country to have undertaken reform and restructuring in power sector to make power supply more efficient and to be able to meet the investment needs of the sector. The State Electricity Board which was a monolithic organisation, looking after generation,transmission and distribution of power was unbundled. The Grid Corporation of Orissa Limited (GRIDCO) was entrusted with the responsibility of Transmission and Distribution Systems, where as Orissa Hydro Power Corporation owned and operated all hydro power generation stations in the State from 1st April'1996. The Orissa Electricity Reforms Act 1995 came into force with effect from 1st April'1996. An independent transparent regulatory regime, Orissa Electricity Regulatory.
Commission(OERC) was established in April'1996 in order to look after the regulation measures and also to promote accountability in the sector and to encourage private sector investment.
Subsequently in April'1999, the distribution business of GRIDCO was privatised when GRIDCO disinvested 51% of its share of its equity holding in Distribution Companies to Private Investors with financial and technical capabilities.
Disinvestment in power distribution sector is a major step in the power sector reform initiative which is now being replicated in other States of the Country.
