Power Grid Corporation of India Limited (POWERGRID) has announced the successful completion of a major inter-state transmission project through its wholly owned subsidiary, POWERGRID Narela Transmission Limited, in a filing to the National Stock Exchange and BSE Limited on February 24, 2026. The project is described as the Transmission System Strengthening Scheme for evacuation of power from Solar Energy Zones in Rajasthan totalling eight point one gigawatt (GW) and was assigned under the Tariff Based Competitive Bidding route. The scheme was developed to transfer large volumes of solar power generated in Rajasthan to different parts of the country through the national grid. As per the official disclosure signed by the company secretary, the scheme was fully commissioned on December 7, 2025 and the formal notification of commercial operation was received by email on February 24, 2026. The assignment to the subsidiary forms part of POWERGRID's wider programme to enhance inter regional transmission capacity and improve grid stability. The project execution is intended to support integration of utility scale solar generation and reduce constraints on power evacuation. Commissioning of the GW scheme further strengthens the transmission network by enabling bulk evacuation of renewable energy from designated solar zones and by providing additional corridors for energy transfer across states. The development is reported to align with regulatory disclosure norms under Regulation 30 of the Securities and Exchange Board of India listing requirements. The operationalisation of these corridors is expected to relieve transmission bottlenecks and support wholesale power flows. The project will support the evacuation of the GW of solar power and is expected to improve grid reliability while facilitating India's clean energy transition. The commissioning represents a significant operational milestone that complements ongoing transmission investments and grid modernisation efforts. Continued development of similar schemes is anticipated to assist states in meeting renewable procurement targets and in ensuring a stable supply of electricity to consumers.
