State of Uttarakhand was formerly known as Uttaranchal. On 9 Nov. 2000, this 27thstate of republic of India was carved out of the Himalayan and adjoining north-westerndistricts of Uttar Pradesh as per the Uttar Pradesh state reorganization act 2000.

The State of Uttaranchal in exercise of the power granted to it under section 63(4) of theState Re-Organization Act, 2000, formed two separate companies in power sector-

Uttaranchal Jal Vidyut Nigam Ltd. – For generation of Hydro electricity in thestate.

Uttaranchal power Corporation Ltd. – For transmission and distribution ofelectricity in the state.electricity in the state.

Enactment of the Electricity Act 2003, a distinct watershed in the Indian Power sector ,made it mandatory for all the States to restructure their SEBs. As per the provisions ofElectricity Act 2003 , the state Government separated power transmission business fromUPCL which was left only with distribution of electricity .

A new company by the name & style of Power Transmission Corporation ofUttaranchal Ltd. was created to handle power transmission business and registered as aGovernment company on 27th May, 2004, under section 617 of companies Act, 1956 .Itstarted functioning w.e.f. 1st June, 2004.

Uttarakhand has a very high potential which is yet to be developed and to give impetus to power sector, Uttarakhand Jal Vidyut Nigam Limited (UJVNL) was formed. UJVNL is a wholly owned Corporation of the Government of Uttarakhand set up for managing hydro power generation at existing power stations and development, promotions of new hydro projects with the purpose of harnessing, the known, and yet to be known, hydro power resources of the State.hydro power resources of the State.
