The Central Electricity Regulatory Commission (CERC) is considering a
proposal on reduction of unscheduled interchange (UI) price from Rs 10 to Rs
7.35 for a unit of power by end-March in an effort to reduce spot price.
UI is the difference between the actual generation and the scheduled
generation from a power project for a particular period of time.
Besides, CERC will be examining a plan for restriction on unscheduled
withdrawal of power, which might be fixed at 10-15 percent of scheduled demand.
If the plan gets notified then the power withdrawal from any grid is expected to
be stopped as soon as the frequency of the grid drops to 49.3 Hz. A power
utility has to begin load shedding as soon as the frequency touches 49.3 to
prevent collapse of the grid. Presently, it happens after the frequency drops at
49 Hz.
Meanwhile, CERC is known to be considering the concept of a no load shedding
tariff for customers who are willing to pay more for zero power cuts.
