Inter State Transmission System project deadline shifts highlight Balsane grid node

Inter State Transmission System infrastructure development continues with the proposed 765/400/220 kV AIS Balsane substation project in Maharashtra. REC Limited is managing the bidding process to select a transmission service provider under the tariff-based competitive bidding model for this high-voltage grid expansion initiative.

The project aims to establish a major evacuation node integrating 765 kV, 400 kV and 220 kV voltage levels. Transmission hubs of this scale often play a critical role within the Inter State Transmission System by absorbing generation capacity and redistributing power flows across multiple grid corridors.

The procurement follows the TBCB framework where the selected developer undertakes design, financing, construction, operation and maintenance of the transmission infrastructure. This model is widely used across Inter State Transmission System projects because it allows tariff discovery through competitive bidding while ensuring long-term asset management by the developer.

The tender timeline has seen several revisions. Originally issued on 9 February 2026, the bid submission date has moved from 23 February to 5 March, then to 12 March and finally to 27 March 2026. Such adjustments frequently appear in Inter State Transmission System tenders where bidders require additional preparation time to evaluate equipment costs, financing assumptions and engineering complexity.

Projects of this voltage class often involve significant capital investment and long procurement cycles for ultra-high-voltage equipment. As Renewable energy India generation capacity grows, large nodes within the Inter State Transmission System become essential to support bulk power evacuation.Coverage of transmission tenders and Inter State Transmission System developments is regularly tracked by EnergylineIndia.com within broader Indian Power news analysis, Transmission Projects, Energy Infrastructure, Power Grid India, Electricity Network.

Indian Power news: 765 kV Balsane EPC package integrates four substations in single PGCIL tender

Indian Power news reports a major transmission infrastructure tender released by Power Grid Corporation of India Limited involving the establishment of a 765/400/220 kV air-insulated substation at Balsane in Maharashtra. The project combines greenfield construction with extension works at three substations, creating a multi-node EPC package designed to strengthen regional grid connectivity.

The tender was issued on 5 March 2026 with a compressed bid submission window closing on 16 March 2026. According to Indian Power news, the engineering package forms part of a broader transmission expansion scheme structured under regulated tariff frameworks typically used in Inter State Transmission System infrastructure development.

The EPC scope requires contractors to execute the full design, engineering, procurement and commissioning of the 765 kV Balsane switchyard. The project will also include extension works at the proposed 400 kV Malegaon substation and upgrades at the operational 220 kV Shivajinagar and Vikharan substations.

These extension works require installation of new bays, protection systems, and communication interfaces to synchronise the new hub with the regional electricity network. Integration with the Vikharan solar generation node also indicates the project’s role in enabling renewable power evacuation.

For analysts following Indian Power news, the tender demonstrates how transmission utilities are increasingly bundling multi-site infrastructure into single EPC packages. Such projects simplify coordination while ensuring synchronised commissioning across multiple substations within expanding Smart grid networks.
