Maharashtra Commissions Major 400 kV Power Line to Strengthen Mumbai's Electricity Infrastructure
The Maharashtra State Electricity Transmission Company Limited (Mahatransco) officially commissioned the Babhaleshwar–Kudus 400 kV double-circuit transmission line on Thursday, marking a significant milestone in bolstering the power infrastructure across the Mumbai Metropolitan Region (MMR). This newly operational line is set to substantially enhance the stability, reliability, and efficiency of electricity supply for key districts including Mumbai, Thane, Palghar, and Ahilyanagar.
Enhanced Power Capacity and Reduced Losses
According to a senior official, the transmission line is expected to reduce transmission losses by approximately 5 megawatts while improving voltage levels throughout the region. More importantly, it enables an additional power transfer capacity of up to 3,000 megawatts, which will be crucial for managing the escalating electricity demand in the fast-growing MMR area.
Project History and Execution Challenges
Originally approved in 2010 with a target completion date of 2013, the project encountered multiple delays due to a range of technical and administrative hurdles. It was ultimately completed in March 2026, with execution carried out by Kalpataru Projects International Limited. The project involved the installation of 715 transmission towers spanning a total line length of approximately 228 kilometers.
Of this extensive work, 485 towers and 304 circuit kilometers of stringing were completed under the Nashik division, while 230 towers and 152 circuit kilometers were handled by the Vashi division, as confirmed by an official statement.
Overcoming Significant Obstacles
A spokesperson from Mahatransco highlighted several major challenges faced during execution. These included obtaining special permissions for passing near the Giant Metrewave Radio Telescope in Pune district, addressing land compensation issues, securing forest clearances, navigating right-of-way constraints, and managing logistical difficulties in material transportation.
In forested areas, materials had to be transported manually, and advanced hotline stringing techniques were employed in certain sections to ensure completion without disrupting existing services.
Benefits for Grid Reliability and Load Management
The commissioning of this line has effectively reduced the load on the existing Padghe–Babhaleshwar transmission lines, thereby improving overall grid reliability. Additionally, it provides an extra power source to the Kudus substation, which is essential for meeting the increasing electricity demands in the Mumbai region.
Acknowledgments and Collaborative Success
Mahatransco credited the successful completion of the project to the cooperation and support from various stakeholders, including local public representatives, revenue authorities, police departments, and forest officials. This collaborative effort was instrumental in overcoming the numerous obstacles and ensuring the project's timely delivery.
