The recently set up state load dispatch centre of the electricity department at Margao is expected to help the department schedule its power consumption more accurately, thereby helping the government save crores of rupees that it would otherwise pay as penalties.
Until around a month ago, power scheduling (determining the power requirements of the state) was done manually. With the new IT supported set-up, the department’s trained engineers are now able to schedule power for the state on a real time basis.
The load in the state is never constant. It decreases in the afternoons, on weekends during the monsoon, and when there are breakdowns. Based on these and other factors, the state load dispatch centre makes and estimation of the expected demand and intimates the Western Regional Load Dispatch Centre about the expected draw of power by the state.
When the state overdraws and even underdraws power beyond a certain limit from central sector generating power stations, it pays a heavy penalty as deviation settlement mechanism charges. Now, however, if the department anticipates a decrease or increase in power consumption, it can reschedule the state’s power requirement based on the real situation and save on energy charges and penalties.
“States cannot underdraw and overdraw power as per their whims and fancies. They are penalised for heavy overdrawing as this can result in the collapse of the grid,” an electricity department engineer said. “The department was sometimes underdrawing, especially when there were faults with feeders that would bring the load down. When the state’s schedule and demand match, it signifies that the state is maintaining grid discipline and that it’s running in profit and doing good business. But when the actual draw of the state deviates from the schedule, a number of problems arise,” the engineer added.
The setting up of a state load dispatch centre is mandatory under the Electricity Act 2003.
The electricity department’s chief electrical engineer N N Reddy said the setting up of the centre is a step in the right direction as it helps the government monitor its consumption and determine excess or shortage of power required in advance and hence, save revenue. Penalty paid by the state for deviating from its schedule would run into over a crore of rupees a month, he told TOI.
