An underground substation is a facility built below ground level to house electrical transformers, with a primary focus on public safety and convenience. In the newly established station in Malleswaram, the transformer is positioned 8 feet below the road surface. BESCOM handles the electrical components, while BBMP oversees civil works. 

The underground station features a 500 KVA capacity oil-free transformer, an 8-way solid-state ring main unit, a 5-way LT distribution box, UPS, an automatic water pump, and an air control system. Provisions for access during repairs are also included. The chamber is designed as a water sump, enclosed by concrete walls on all sides, ensuring that pedestrians can safely traverse above it. Even in the event of a transformer explosion, there will be no impact on the surface, thus helping to prevent power outages and related accidents.
