Originally transmission lines were built directly from energy source to load. Later they formed a mesh and voltages were raised to increase capacity. Today lines seem to be everywhere and the public is saying 'no more, thank you'. This Address explores how transmission capacity can be extended by boosting voltage, line sharing etc. The ability of power electronics to assist the system or to convert a seg ment to DC is shown. An Indian example demonstrates the benefits of DC interconnection of systems since it allows them to maintain their independence. What are the limits of transmission, a nd why can blackouts occur? When and where does each conventional or power electronic solution apply?
