Issues related to non-operation of Intra-state ABT in India

A lot of reforms are being implemented in India for overall improvement of power system stability and grid discipline. Availability Based Tariff (ABT) is one such reform which is beneficial to all the stake holders of power system. This regulatory reform is being implemented in two stages i.e. Interstate ABT and Intrastate ABT. The interstate ABT mechanism has been made fully operational at regional level whereas the Intra-state ABT mechanism is still being implemented in some states. Non operation of Intra-state ABT mechanism in these states has resulted in various issues related to grid indiscipline and exorbitant financial implication on the distribution utilities. It also creates the anomaly between state and central regulatory bodies. This paper presents study and analysis of these issues in detail and its implication on power system.
