POWERGRID has received a Letter of Intent (LoI) for an Intra-State Transmission Project in Karnataka through the Tariff Based Competitive Bidding (TBCB) route, strengthening the state’s transmission infrastructure and renewable energy evacuation capabilities.
The project envisages the establishment of a 3×500 MVA, 400/220 kV Air Insulated Substation (AIS) at Humnabad in Bidar district, along with associated 400 kV and 220 kV transmission lines.
The scope of work also includes bay extensions at existing substations in Karnataka to strengthen grid connectivity and facilitate the seamless flow of electricity across the state.
The proposed transmission infrastructure is expected to play a crucial role in pooling and evacuating renewable energy generated in North Karnataka to meet the growing electricity demand in Southern Karnataka.
The project assumes significance amid Karnataka’s efforts to strengthen its power transmission network and integrate a larger share of renewable energy into the state grid.
With the new Humnabad substation and associated transmission links, the project will enhance transmission capacity, improve grid connectivity and support the reliable movement of power from renewable energy-rich regions to demand centres.
The LoI marks an important step for POWERGRID in expanding its presence in the intra-state transmission segment through the competitive bidding route.
