Adani Energy Solutions Ltd., India’s largest private-sector power transmission company, has announced the successful commissioning of the Karur Transmission Ltd (KTL) project. The project included the establishment of the 400/230 kV, 1000 MVA Karur Pooling Station and an associated transmission line spanning 8.51 circuit kilometers in Tamil Nadu.
“With a transformation capacity of 1,000 MVA, this project will facilitate the evacuation of power from renewable sources in the Karur/Tiruppur Wind Energy Zone. Additionally, it will strengthen the Southern regional grid and support the integration of renewable energy sources on a large scale,” stated AESL.
The Karur/Tiruppur Wind Energy Zone is a key wind corridor in Tamil Nadu, with significant capacities in wind energy and several under-construction wind farms. AESL was awarded this project to ensure the smooth evacuation of up to 2.5 GW of green power produced in the region. This project will provide industrial, commercial, and residential consumers with enhanced access to reliable and clean energy.
AESL secured this project on a build-own-operate-maintain basis through the tariff-based competitive bidding (TBCB) route in December 2021.
“Despite numerous challenges, AESL executed this project in a fast-track mode, taking into consideration the topological challenges while minimizing ecological impact. Several innovative approaches were employed during the execution, including the use of high-boom RMC machines for concreting work, high-boom lifts and cranes for tower erections, and the implementation of advanced cybersecurity endpoint solutions through the latest SCADA system. The project also involved round-the-clock work in multiple shifts, allowing for enhanced progress. AESL’s execution prowess was displayed through the erection of two 48-MT towers in under 24 hours each, significantly surpassing the usual rate of 5-6 MT/day,” stated AESL.
“Furthermore, AESL successfully completed critical tasks such as the shutdown of the 400 kV D/C Pugalur-Pugalur (HVDC) line and the erection of tower structures under the constraints of the existing transmission line.”
