The Central Transmission Utility (CTU) is a crucial organization in the power sector, responsible for the planning, development, and coordination of the high-voltage electricity transmission system across the country. In India, the Central Transmission Utility of India Ltd. (CTUIL) serves this role and is a wholly owned subsidiary of the Power Grid Corporation of India Limited (POWERGRID). The CTU operates independently to ensure the efficient and reliable transfer of electricity from power generation stations to various distribution networks and large consumers. Its key responsibilities include preparing long-term transmission plans, granting connectivity and access to power generators and users, coordinating between different stakeholders in the electricity market, and overseeing the development of the Inter-State Transmission System (ISTS). By maintaining neutrality and focusing on national interest, the CTU plays a vital role in strengthening the national grid, enabling open access for competition, and supporting the integration of renewable energy sources into the power system.
