Over 150,000 Transformers, 498 Substations to Power Hyderabad’s Underground Power Infrastructure

Hyderabad is on the verge of a transformative infrastructure upgrade, with plans underway to replace traditional overhead (OH) power lines with underground (UG) electricity cables. Spearheaded by the Telangana government, this ambitious initiative is designed to enhance safety, ensure reliable power supply, and support the city’s sustainability goals.

The move comes in response to frequent disruptions caused by heavy rains and strong winds, which often damage overhead lines, resulting in power outages, short circuits, and, in some cases, fatal accidents. Transitioning to underground cabling will significantly mitigate these risks, promising a more secure and consistent power supply for over six million electricity consumers in the city.

To kick-start the project, Telangana’s Minister for Power, Bhatti Vikramarka, recently led a team to Bengaluru to study its underground cabling network. Drawing inspiration from Bengaluru’s success, Hyderabad will begin with a feeder-wise survey—starting from main roads and expanding gradually into residential areas. If all goes as planned, groundwork for the project will commence by the end of August.

The project’s scale is impressive. According to official estimates, the initiative will involve laying 1,280 kilometers of 33 KV and 1,025 kilometers of 11 KV underground cables. This infrastructure will be supported by the installation of 498 new substations and more than 150,000 distribution transformers.

An official from the Telangana Southern Power Distribution Company Limited (TGSPDCL) highlighted the project’s multifaceted benefits: “Underground cabling ensures uninterrupted power during storms, greatly reduces the risk of electric shocks and accidents, and lowers long-term maintenance costs. It also improves the visual appeal of the city and aligns with Hyderabad’s urban planning goals.”

The official also pointed out that many private individuals, businesses, and gated communities have already shifted to underground cabling. “For newly constructed residential buildings and upcoming gated communities, adopting UG lines is much easier and more practical,” he added.

Environmentally, the project supports the preservation of urban greenery by eliminating the need for frequent tree pruning—a key benefit under the state's Haritha Haram program. With coordinated planning and execution, Hyderabad is set to emerge as a model for smart and sustainable urban power infrastructure, blending safety, efficiency, and environmental responsibility.
