Adani's 1,000 MW power boost for Mumbai

04 Oct 2023 CW Team

Mumbai's increasing energy requirements have been significantly enhanced with the launch of the Kharghar Vikhroli Transmission (KVTL), which is set to provide an additional 1,000 MW of power to the city. The existing capacity of the transmission corridor is inadequate to accommodate more power into the city, making this project crucial for Mumbai. The necessity for this project is underscored by the memory of grid failures on February 27, 2022, and October 12, 2020, which plunged parts of Mumbai into darkness. The new Kharghar-Vikhroli line is not only expected to illuminate the city but also strengthen vital transportation networks, including bullet trains, Metro Rail, and city railways. Covering around 74 circuit kilometres, the KVTL incorporates 400 kV and 220 kV transmission lines. One of its notable features is the 1,500 MVA 400kV Gas Insulated Substation (GIS) at Vikhroli, a first for Mumbai. The substation is designed for compactness, occupying an area of approximately 9,500 sq m. It is built with a unique vertical configuration, where 400kV and 220kV GIS are stacked vertically, optimizing the use of space. During the implementation of the KVTL, Adani Energy Solutions (formerly known as Adani Transmission) faced various challenges. Diverse terrains posed unique obstacles, such as the construction of towers in creek areas using floating barges. In certain urban areas, height limitations were effectively managed by introducing specially designed horizontal configuration towers.

Smart Roads, Smarter India

India’s infrastructure boom is not only about laying more kilometres of highways – it’s about building them smarter, safer and more sustainably. From drones mapping fragile Himalayan slopes to 3D machine-controlled graders reducing human error, technology is steadily reshaping the way projects are planned and executed. Yet, the journey towards digitisation remains complex, demanding not just capital but also coordination, training and vision.Until recently, engineers largely depended on Survey of India toposheets and traditional survey methods like total stations or DGPS to prepare detai..

What Does DCPR 2034 Mean?

The Maharashtra government has eased approval norms for high-rise buildings under DCPR 2034, enabling the municipal commissioner to sanction projects up to 180 m on large plots. This change is expected to streamline approvals, reduce procedural delays and accelerate redevelopment, drawing reactions from developers, planners and industry experts about its implications for Mumbai’s vertical growth.Under the revised DCPR 2034 rules, buildings on plots of 2,000 sq m or more can now be approved up to 180 m by the municipal commissioner, provided structural and geotechnical reports are certified b..
