The most important benefits and challenges of interconnected electricity networks: In terms of the electricity value chain, transmission on average accounts for less than 10-15% of the final cost paid by the end-user for each kWh. Today, however, transmission is becoming a key issue for the effective operation of liberalised markets and their further development. An integrated and adequate transmission infrastructure is of utmost importance for ensuring the delivery of the most competitively priced electricity to customers, both near and far from power generating facilities.
