ISLAMABAD: Pakistan is facing massive power shutdown at the beginning of Monday due to failure in this is national electricity grid. Power was out in Everybody of The country’s major cities, including Karachi, Islamabad, Lahore and Peshawar, were confirmed by the energy ministry.
although the minister for Power Khurram Dastgir Khan called the deadline of 22:00 for full recovery of power supply, power failed to meet the deadline and most cities and towns of the country was left without power in cold winter night.
Although power recovery process started in federal capital around 19:34 after a 12-hour shutdown, other cities of the country was still facing a complete blackout at midnight.
Ministry in the statement said the network “had suffered losses of the frequency that caused major breakdown”, at approximately 07:30 local time, and that work work was underway to restore system.
In an interview minister of The energy of Khurram Dastagir explained what happened. “In winter, demand for electricity is shrinking across the country so as an economic measure we are temporarily closing down our power generation systems at night. But when power factories were restarted on morning of On January 23, “frequency fluctuations and voltage fluctuations” were detected. in southern Pakistan, “somewhere between Dadu and Jamshoro,” he said. Hence, this led to “power generator sets for shut down one from one”.
What is frequency?
When you turn on household appliance such as a kettle or laptop charger powered by AC current. This indicates that the electricity alternates between positive and negative voltage. This back-forward motion or “oscillation” is called electrical frequency.
Mains frequency measured in Hertz (Hz) is the technical term which refers to of times alternation cycle occurs every second. Currently, 50 Hz is the most commonly used frequency. in weight of in the world power systems, including Pakistani.
Because the equipment in your housefactory or office is designed to run at 50 Hz within a tight tolerance, maintaining the frequency of our power offer critical. it reason why is everyone flipping their tech off when there are fluctuations in voltage or frequency of electricity. If this is not done, there is a possibility of equipment and equipment is damaged.
issue that the frequency is difficult to control; if exactly amount of the required electricity does not correspond to the generation, frequency of electricity on the mesh may be affected.
If there is more demand for electricity than supply, for for example, the frequency will be reduce. When there is excess of power, the frequency rises. To make a deal even more complicatedmargin of error extremely narrow.
What happens when the frequency drops?
During a conversation with Benefit sources from power division explained that, “according to the initial findings, issue showed up around 07:34 due to a violation in Frequency of in national mesh, which caused major breakdown.”
The sources further elaborated that “the frequency was reduced due to malfunction in Guddu-Quetta power line and other causes and problems behind guilt is established.
The frequency decreases if we feed in too few to meet demand. To avoid power shutdown, automatic load shedding strategy activated when this happens. It’s connected with fact that if the frequency drops too low, power plants shut down one from one until the network fails completely.
Here’s what seems to have happened in happening of recent power black out. demand was higher than a generation of the grid that led to the dominoes effect causing power plants are switched off and unplugged to save expensive power generation equipment.
At the same time, some sources on the basis of anonymity claimed that issue arose when government made the desire to increase the contribution of thermal power into the grid as Hydel’s power generation fell.
What the government done?
Initially, all provinces experience power shutdowns. Areas including Karachi, Lahore, Faisalabad, Toba Tek Singh, Sargodha, Shor Kot, Pir Mahal, Mukran, D. G. Khan were facing a power crash.
To sum up, the entire province of Sindh and Balochistan did not have power, or have it intermittently. Regions in South Punjab and Khyber Pakhtunkhwa also experiencing darkness.
national the regulator made efforts to restore uninterrupted power consumers. According to the National Electricity Regulatory Authority (NEPRA), “[It] paid serious attention of countrywide power accident and instructed the National Freight Forwarding Company (NTDC) to provide a detailed report in in this regard.”
Furthermore, in In a statement, the regulator assured that the outage was not its fault, as “[It] previously fined on similar operation, partial/full blackout(s), system collapse(s), collapse(s) of the tower in in year 2021 and 2022 and constantly issues directives and recommendations on mitigation of such events same.”
Besides, power division also issued a statement saying that “work on recovery of electricity was started and is currently in full download as multiple grid stations of IESCO and PESCO currently restored in phase wisely avoid more losses”.
Even though the energy minister claimed that the energy would restored within 24 hours, sources say this is unlikely given the magnitude of in issue adding that it may take up up to 48 hours to ensure uninterrupted power supply to all areas.
During a conversation with Benefit, a source also said the government’s efforts to restore supply of electricity facing unprecedented challenges that further exacerbate the situation.
According to Dastgir’s tweet, “Electricity restored partially in distribution companies Islamabad, Peshawar, Quetta, Multan and Sukkur.
Although work restoration work in progress national grid, fine reason for failure is not yet clear. Further statements and reports are expected to clarify this. issue and potentially prevent it in in future.
