The Central Electricity Authority (CEA) has issued a draft manual on transmission planning criteria.
Considering large scale renewable energy integration, growth of load, increasing fault level, right of way issues, technical advancements, notification of transmission rules, the manual on transmission planning criteria was proposed to be revised. The draft manual covers the planning philosophy, the information required from various entities, permissible limits, reliability criteria, broad scope of system studies, modelling and analysis and gives guidelines for transmission planning. The planning criteria are primarily meant for planning of inter-state transmission system (ISTS) down to 132kV level and intra-state transmission system (In-STS) down to 66kV level, including the dedicated transmission lines. The commission has invited comments and suggestions on the draft by June 30, 2022.
