Indian Power Scenario was characterized by low frequency due to continuous power deficit most of the time. As the country moved towards being a power surplus, reforms were introduced to manage grid discipline and fair pricing. ABT Mechanism a frequency-based pricing mechanism for unscheduled electric power transactions was adopted in the year 2002. As the coordinating agency of SEBs, the Load Dispatch Centre became the apex body to ensure the integrated operation of the power system by coordinating generation and transmission to ensure a mechanism for safe and secure grid operation, monitoring, and levying penalties and rewards.

Calculations of ABT are complex needing real-time parameters of power generation. Implementation of ABT demanded a complete solution to monitor changes in Schedule, Grid frequency, and other dynamic plant operational parameters. The computation of DSM is based on real-time data on deviation from the power generation schedule
