Power Ministry has promulgated the Electricity (Transmission System Planning, Development and Recovery of Inter-State Transmission Charges) Rules 2021. This paves the way for overhauling of transmission system planning, towards giving power sector utilities easier access to the electricity transmission network across the country.<br />''<br />'' At present, generating companies apply for long-term access based on their supply tie-ups, while medium-term and short-term transmission access is acquired within the available margins. Based on Long Term Access application, incremental transmission capacity is added. A number of sector developments, such as the increasing focus on renewable energy, and the development of the market mechanism, necessitated a review of the existing transmission planning framework based on LTA. <br />
