Minutes of 37thMeeting of the Standing Committee on Power System Planning in Southern Region
LILO of both lines (i.e., NLC TS2 – Alundur and NLC TS1 Exp – Alundur) will over load the existing 400 kV lines at Neyveli complex. Hence, it is suggested that LILO of only one circuit Neyveli – Trichy 400 kV D/C line as agreed earlier to provide start up power to the plant may be carried out. The evacuation system for the ILFS generation, Nagapattinum – Salem 765kV S/C line & Salem – Madhugiri 765kV S/c line may be speeded up to evacuate power from IL&FS. 3.

SRLDC stated that there is need to clarify that system strengthening required for evacuation of power from generating stations is necessarily a part of ATS(Associated Transmission System) and should be in place before the commissioning of generation units. In the absence of commissioning of entire transmission system required for evacuation of power from generating station and feeding into load centres, the generation leans on ISTS and leads to congestion in the network. He also emphasized the need of commissioning of associated 220kV lines in the time frame of 400kV network as the mismatch in commissioning of these elements would lead to congestion and TNEB would need to back down their generation to contain loading. These provisions were agreed by TNEB. 3.7
DGM(CTU) agreed with SRLDC view and stated that in the absence of commissioning of the proposed transmission system, generators for which transmission system has not commissioned should be backed down first and the access of other generators including ISGS generators should not be affected. These provisions were also agreed by TNEB. TNEB stated that for the Udangudi projects, they are proposing to build an 3.8
Udangudi Pooling Station where both the Stage‐I and Stage‐II would be pooled with following connectivity lines: Connectivity for Udangudi Power Project Stage‐I (2x660MW): i) 400kV DC Quad line to the Udangudi Pooling station. Connectivity for Udangudi Power Project Stage‐II (1x800MW): i) 400kV DC Quad line to the Udangudi Pooling station. ii) 400kV DC Quad line to the Udangudi Power Project Stage ‐1 ‐2x660MW These lines and the Udangudi Pooling Station would be in addition to the earlier planned system. This system for Udangudi projects was agreed provided the Udangudi Pooling Station is commissioned along with the generation project commissioned first. 3.9
Members agreed to the proposal of TANGEDCO with the above modifications and the provisions as mentioned earlier. 4.
