The proposed infrastructure additions to meet the peak demand of 4459MW are as follows.
(i) 400KV Grid S/S – 5nos. (Keonjhar,Lapanga,Duburi,Bolangir & Uttara)
Uttara,Bolangir(new),Keonjhar,Banai, Laxmipur, Dhamara and Hindol Road)
Kuchinda,Bhawanipatna,Boud,Banki,Kalunga,Barbil,Karadgadia,Uttara,Bolangir(new), Dhenkanal(new) Kuanrmunda,
Dhamara and OCL (switching station)
- Reactive power compensation by installing Shunt Capacitor of 760MVAR in different Grid S/S of OPTCL.
- Associated Transmission Lines
(a) 400kV Transmission Lines - 2nos - 135 Kms.
(b) 400kV LILO Lines - 6nos.
(c)220kV Transmission Lines - 14nos. -648.59Kms.
(d) 220kV LILO Lines - 10nos.
(e)132kV Transmission Lines - 29nos. 992.91Kms.
(f) 132kV LILO Lines - 21 nos.
Augmentation and Addition of Transformer Capacity with 3rd Bay of Existing Grid S/S
Besides the above, the proposal for capacity addition with augmentation and addition of transformer capacities with 3rd bay in 50 nos. existing Sub-Stations with transformation capacity by 2612.5MVA. Subsequently to meet the additional load of RGGVY and BGJY further 7nos. of transformers required to be commissioned at Jaynagar,Junagarh,Bhadrak,Karanjia,Kamakshyanagar,Rajgangpur and Budhipadar Grid Sub-Stations.
Long Term Transmission Plan for 12th Plan Period.
In addition to 11th plan period, integrated Transmission Planning of OPTCL network for 12th plan period has been prepared taking the system peak demand of 6363MW and additional generation of 4669MW as state share from 4nos. IPP taken in 11th plan period along with following 11nos. upcoming IPPs
In addition to the projects proposed in 11th plan period the following infrastructure additions have been kept to meet the peak demand of 6363MW.
- 132/33kV Grid S/S at Olaver
- 132/33kV Grid S/S at Titlagarh
(iii) Reactive power compensation by installing Shunt Capacitor of 200MVAR at Duburi and Bhadrak region and 150MVAR at Berhampur region.
(iv) Associated Transmission Lines
132kV LILO Lines - 2nos.
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.
