    Prioritization Study of Up-coming Projects under 11th Plan period
                Subsequently, for the purpose of implementation of the proposed projects under Transmission Planning of 11th plan period, System Study work has  been assigned to M/S PRDC Ltd. Bangalore to conduct the Prioritization study by phasing the total upcoming projects in coming 4years i.e. during 2009-10.2010-11,2011-12,2012-2013.The first report of prioritization from M/S PRDC is awaiting.


    Proposal for Power Evacuation from Up-coming IPPs through 400KV Ring System
    In the mean time 33nos. of IPPs have planned to install their power plant in Orissa including the above 15nos.. It is expected that at the end of 2020 the quantum of power generated by those IPPs. will be to the tune of 46,070 MW and Orissa will avail its state share about 25% .
    OPTCL has also initiated necessary action for evacuation of  state share power from up-coming IPPs through 5nos. STU Sub Pooling Stations at Jharsuguda,Bamur,Nisa/Boinda, Angul and Khuntuni, which will be connected to 3nos. CTU (765KV) pooling stations at Jharsuguda, Angul and Dhenkanal to be connected by PGCIL for inter-state long term open access.

         The above Sub-Pooling Stations will be a part of the 400KV Ring system with 10nos. 400KV Grid Sub-Stations and 1482 KMs of 400KV lines.The proposal of 400Kv ring system has already been apprised to CEA and for the feasibility of the scheme the comprehensive study work has been assigned to M/S PRDC Ltd.  It will facilitate the state to evacuate the surplus power and to utilize the required power effectively and transmit these power through available downstream network.
