The HPERC has finalised amendments to its regulation on deviation settlement mechanism (DSM). As proposed earlier, the HPERC has included the concept of area clearing price. It has also finalised additional charges in case of violation of the requirements with regard to sustained deviations. It has fixed a 0.5 MW deviation limit for a time block of up to 10 MW. For a time block of up to 25 MW, the maximum permissible deviation is 1 MW. For deviation of a time block of up to 100 MW, deviation of 2 MW is allowed, while for more than 100 MW, the permissible deviation is 10 MW. Each violation will attract an additional charge of 10 per cent on the time block DSM.
