Power Transmission Line Project

a. What are the major steps to be taken before the actual tendering process (i.e. Process for invitation for bids) can be initiated? Include approvals have to be taken from various agencies outside the Transco. 1. Transmission System Planning 2. Feasibility Report Preparation 3. Approval from Board of Directors/Government 4. Gazette Notification 5. Signing of Bulk Power Tariff Agreement. 6. Funding Tie up. 7. In Principle Approval from Ministry of Environment & Forest. 7. Design, Engineering & Specification finalization 1. Transmission System Planning & System Engineering Purpose: Transmission Planning Studies are carried out for evacuation of power from a Power Station, which is either newly constructed or where a new generation capacity is added, for grid strengthening, for intra-regional exchange of Power, for inter regional connection for exchange of power. These studies are carried out keeping in view the long-term power plans of the country framed by CEA. Load flow, short-circuit; stability and Over voltage studies are the ones need for this purpose. Practices: From the Point of view of power system planning and system engineering following are needed: i. The data and time schedules for carrying out Planning Studies are to be collected from various Organizations, such as CEA, Planning Commission, Respective Electricity Boards (SEB)/Electricity Departments (ED), Regional Electricity Boards (REB), Regional Load Dispatch Centers (RLDC), Power Utility’s own system and operational data etc. These are corresponding to different time frames including present scenario and comprises of Generation Details, Load (both Active and Reactive), Details of Transmission Network at different voltage levels, Transformer Capacity, Details of Reactive Compensation ii. Long term transmission plans are evolved considering the long term power transfer requirement from generation resources to Load Centers.
