Further, the fourth amendment in 2019, linked the deviation charges to the daily average market prices discovered in the day-ahead market (DAM) segment on the power exchanges Charges for deviation was linked to the average frequency of timeblock.
In DSM regulations 2022, the deviation charges for the time block was delinked the grid frequency and based on the time-block wise prices discovered in the day-ahead market (DAM), real-time market (RTM), and ancillary services market (ASM), instead of average day prices in the DAM, thereby increasing market price risk for the power plants.
