Patran Transmission Company Limited
Project Synopsis:
“Patran Transmission Company Limited (PTCL)” is a Special Purpose Vehicle 100% acquired by the M/s. Techno Electric and Engineering Company Limited (TEECL) from PFC Consulting Ltd. TEECL was successful in bagging a concession from PFC Consulting Ltd for building a transmission project “Transmission System for Patran 400kV Substation” located at Patran, Punjab. This Inter-State Transmission System project was awarded to TEECL by PFC Consulting Ltd. and the Letter of Intent was issued on September 17, 2013. The Central Electricity Regulatory Commission has granted Transmission License No. 26/Transmission/2014/CERC dated July 14, 2014 under Section 14 of the Electricity Act, 2003 to PTCL. The Transmission for Patran 400kV S/s is on build, own, operate and maintain basis.

Project Description:
Patiala and Sangrur district of Punjab has a lot of agriculture load. A partial Grid Disturbance had taken place on 20th July 2011 and analysis of Grid disturbance had also indicated the requirement of a 400/220kV substation in this area. In the vicinity there are 5 nos of 220KV grid stations, namely Mansa, Rajla, Sangrur, Sunam & Patran, having total transformation capacity of about 1180MVA. In addition, 3 nos of 220kV new substations are also coming up in the area at Pasiana, Bangan & kakarla. Accordingly to meet the growing load a 400/220kV substation at Patran was proposed.

The 400/220kV S/s Patran would be connected to the grid by LILO of Patiala-Kaithal 400kV D/c. To avoid unbalanced loading, LILO of both circuits was proposed. From these substations, 220kV lines can be drawn to new Patran, Mansa, Pasiana etc S/s. Looking into load growth potential it is expected that 800-900MW load would be there in the vicinity. In view of the above 2x500MVA transformers were proposed.

Considering the fact that the location of the substation is in a very fertile area of the Punjab where the acquisition of land is going to be a challenging task. Accordingly it was proposed to develop this substation as Gas Insulated substation. The present scope would include 6 nos of 400kV bays (4 nos for loop in loop out of Patiala-kaithal 400kV D/c at Patran and remaining two for transformers) and 8 nos of 220kV bays (two for 400/220kV transformers and 6 Nos of 220kV line bays). Space provision for future bays would include 6 nos of 400kV bays and 6 nos of 220kV bay.

Establishment of Patran alongwith LILO of both circuits of Patiala-Kaithal 400kV D/c line at Patran was agreed to be taken up as regional strengthening scheme in the 30th Standing Committee meeting of Northern Region held on 29.12.2011 and in the 25th NRPC Meeting held on 24.02.2012.

Therefore, the 400 KV Transmission System comprises of LILO of Both circuits of Patiala-Kaithal 400 kV Double Circuit triple snow bird Line at Patran (5 KM) and 400/220 kV Substation with 14 Bays at Patran, Punjab. The inter-state network will have a system capacity to evacuate 1200 MW of power.

Scope of Project:
The 400/220kV substation is GIS substation with one and half breaker scheme and rated for 50kA. Triple Snow Bird Bundle Conductor is utilized for LILO of the line.

As per CERC Order, PSPCL shall be liable to bear Transmission charges from SCOD / actual commissioning whichever is later till commissioning of the downstream system post which the assets shall be considered under POC. Downstream 220KV system of this project was in the scope of PSPCL who connected this 400KV Patran Substation through 220KV Lines only on May 18, 2017 after substantial delay.

At present, amount payable by PSPCL as per CERC Order dated January 4, 2017 in Petition No. 155/MP/2016 is Rs. 10.25Crores. This is observed that PSPCL, despite follow-up at various levels, have failed to pay any monthly bills of outstanding dues even after lapse of substantial period after due date as per Transmission Agreement. Thus, we are regularly approaching to PSPCL for the payment of monthly bills.
