• Technical and Economical feasibility studies are carried out between CEB and Power Grid India to interconnect two Networks by DC link.
• A Joint Technical Team has been appointed
Transmission Planning
Challenges
• Delay of implementation of committed transmission infrastructure due to Environmental and Social Considerations
• Raising of Finance for the Development Proposals
• Integration of Indigenous Renewable Energy Sources to meet the Renewable energy targets – Transmission Infrastructure development – out of hand Implementation schedules – Operational Planning restrictions
• India-Sri Lanka cross border interconnection – Selecting most feasible line route – Section of interconnection type (VSC or LCC) – Power exchange agreement
• Optimizing the reactive power requirement in the network • Human Resource Development and Capacity Building.
