Tata Power Company has introduced an innovative solution called Tower within Tower to address the challenges associated with replacing transmission line towers. This approach, specifically designed for the 110 KV power transmission towers in Mumbai, enables the construction of new towers within the existing tower space. By utilising this method, the need for land compensation and acquisition is significantly reduced. Metropolitan cities like Mumbai often encounter difficulties when it comes to replacing transmission line towers, primarily due to the high costs and complications involved in land compensation and acquisition. These projects frequently face delays due to issues related to land and compensation. The introduction of this new concept by Tata Power Company offers a cost-effective and efficient solution to overcome these challenges. The implementation of the Tower within Tower concept for 110 KV lines in Mumbai is the first of its kind. These transmission towers play a critical role in ensuring a consistent and uninterrupted supply of electricity to the city. Explaining the concept, a spokesperson for Tata Power stated, With the innovative process of 'Tower within Tower,' there is no need to completely dismantle the existing tower. Instead, the new tower can be erected within a smaller space inside the existing tower. This approach not only expedites the completion of pending transmission line projects but also reduces the construction costs compared to traditional methods. Moreover, it saves approximately 30 per cent of the construction time, allowing these new towers to be built in less than a month. Tata Power Company currently operates a total of 3,000 transmission towers with a capacity of 110 KV, and the installation of the new narrow-based towers will be exclusively carried out within the existing towers. As a part of the initial implementation, four new towers have already been constructed in Kalyan. Furthermore, Tata Power has plans to construct additional towers along the transmission corridor in the Diva and Mumbra areas.
