What Would Actually Make Karachi’s Electricity Outages Stop?

The protest camps raise a question that engineering can help answer—which measurable changes would bring households fewer blackouts and faster restoration?

A Karachi household judges electricity reform when the fan keeps running, the water pump works, and a child can finish homework without another blackout. With protests again focusing attention on prolonged outages, the useful question is what must change for those interruptions to become fewer and shorter.

Business Recorder reported on September 27 that Jamaat-i-Islami had established 25 protest camps across Karachi, with K-Electric’s load-shedding among its complaints alongside the petroleum levy and power-producer agreements. The campaign deserves an answer that goes beyond competing political statements.

Karachi needs an independently checked account of why electricity is interrupted, which repairs and operating changes address those causes, and whether consumers actually receive better service.

First establish why the lights went out.

Several different problems can produce the same dark room. A utility may deliberately disconnect a feeder, the circuit supplying an area, under a load-management policy. A transformer or cable may fail. Maintenance may require a planned shutdown. An upstream supply constraint may affect several neighborhoods at once.

Treating every interruption as one undifferentiated problem leads to the wrong remedy. Replacing a transformer cannot end cuts imposed for commercial reasons. Changing a load-shedding policy cannot repair damaged cables.

Each interruption should therefore carry a clear cause, start time, affected customer count, and restoration record. Scheduled cuts, equipment faults, maintenance, and upstream events should be reported separately, alongside a total that reflects the household’s complete experience.

End feeder cuts that penalize paying neighbors.

K-Electric’s published FAQs describe segmented load-shedding linked to feeder losses and payment recovery. That policy must be distinguished from equipment faults.

In reporting on NEPRA’s August 31 order, The Express Tribune stated that very-high-loss feeders serving about 1.18 million consumers recorded average daily outages of 12 hours and 14 minutes against a ten-hour schedule. This finding concerned the examined feeder category, not every Karachi household.

Business Recorder’s September 2 account said NEPRA directed KE to end unannounced and excessive outages and feeder-level cuts based on aggregate technical and commercial losses. It reported directions for targeted action against theft and defaults and a time-bound aerial bundled cable plan and compliance report within 30 days.

KE said it was reviewing the order and would respond within the stipulated period. Publication of the response and verified follow-up would show what changed after the directions.

Count interruptions and hours without power.

Two established indicators translate reliability into terms readers can understand. SAIFI measures the average number of sustained interruptions per customer over a reporting period. SAIDI measures their average total duration.

Both matter: fewer blackouts are little comfort if the remaining ones last much longer.

NEPRA’s FY 2024–25 performance report records K-Electric’s interruption frequency at 68.46 per customer in its table and interruption duration at 4,152.59 minutes, roughly 69 hours. These are historical reported indices, not a measurement of every Karachi household’s present experience.

The same report lists KE’s average daily load-shedding at 5.2 hours as a separate measure. These series should not be added or treated as interchangeable without reconciling their definitions and coverage.

The regulator also flags uncertainty in outage recording across distribution companies, particularly on low-voltage networks. That makes transparent measurement essential.

KE should publish monthly feeder-level results, explain inclusion rules, and identify any excluded events. Citywide averages should sit beside the worst-served neighborhoods, the share of customers experiencing repeated interruptions, and the longest outages.

A feeder exempt from scheduled load-shedding can still suffer faults. Improvement in better-served areas can also obscure persistent hardship elsewhere.

Fix overloaded equipment before it fails.

The next question is whether the assets carrying electricity can withstand actual demand. Transformer ratings alone do not answer it. Engineers need peak loading, time spent above safe limits, temperature, phase imbalance, and repeat-failure records.

A transformer that repeatedly trips on hot evenings may need load redistribution, reinforcement, or replacement, depending on the diagnosis.

A credible program would prioritize the circuits causing the most lost customer-hours, inspect deteriorating joints and cables, correct poor connections, and balance loads between phases.

Publication should track overloaded assets identified, work completed, and failures after intervention. The number of transformers purchased is an input; fewer interruptions after commissioning is the result.

Earthing, insulation, and safe working procedures must remain part of that result.

K-Electric describes an advanced distribution-management-system pilot in one cluster and a framework that uses asset health to guide maintenance. These initiatives provide a useful starting point for scrutiny.

Pilot results should disclose the customers covered, reductions in interruptions and repair times, and costs before expansion is presented as proven success.

Restore healthy streets while repairing the fault.

One damaged section need not keep an entire feeder disconnected until repairs finish. Suitable switching equipment can isolate the fault and restore unaffected sections through an alternative supply route.

Automated fault location, isolation, and service restoration can accelerate that process where the network is designed to support it. This is established engineering, although benefits depend on local conditions.

A US Department of Energy study of distribution automation found fully automated switching reduced customer interruption minutes by about 53 percent across the evaluated events compared with estimated outcomes without the technology. That is evidence of potential, not a forecast for Karachi or a promise to eliminate scheduled load-shedding.

An alternative feeder must have spare capacity, acceptable voltage, and coordinated protection. Communications and controls must remain dependable during an outage.

Closing a switch without those checks can transfer an overload or create a safety risk.

Karachi’s useful measure is the proportion of eligible faults for which healthy sections were safely resupplied, together with the time taken and customers restored.

Make faster restoration a verified outcome.

A complaint being marked closed is not the same as electricity returning.

Restoration records should distinguish detection, crew dispatch, arrival, fault isolation, and final repair. Consumers should receive a realistic restoration estimate and updates when it changes.

Spare transformers, cable joints, trained crews, and safe access can be as important as a new control room screen.

The public should see median restoration time and the time within which 90 percent of interruptions are resolved, as well as repeat faults and reopened complaints. Those measures reveal the long delays hidden by a simple average.

Voltage performance should also be checked at representative customer connections: supply that returns at persistently poor voltage is not a complete restoration of service.

Reduce losses without disguising their causes.

Technical losses are energy dissipated in equipment and conductors. Theft, inaccurate metering, and billing errors require different interventions; unpaid bills create a collection problem.

A combined loss-and-recovery measure is useful financially but cannot identify which engineering repair is needed.

NEPRA records KE’s FY 2024–25 recovery ratio at 90.56 percent. Collection matters to financial sustainability; it does not measure reliability.

Meters at the feeder, transformer, and customer levels can help reconcile energy flows and locate discrepancies. Smart meters can support outage detection where their communications and systems permit it, but they do not create supply capacity or repair a weak network.

Insulated aerial bundled cables, accurate billing, regularized connections, and targeted enforcement should be assessed through measured loss reduction and improved service.

Recovery action should follow applicable rules and individual evidence, with paying consumers’ service protected.

Give Karachi a delivery plan; it can test

A practical response would begin with a 90-day program to verify outage records, identify the worst-performing feeders, inspect recurring failures, and publish funded corrective work.

Larger reinforcement and automation projects should have commissioning milestones and named delivery responsibility.

Where generation, fuel, or import availability constrains service, KE should disclose that constraint and its remedy rather than attribute it to a local equipment fault.

NEPRA should independently check the data and follow up on delivery, while government agencies address access, enforcement, and infrastructure coordination within their responsibilities.

Comparing the same feeders through similar seasons, with changes in demand and weather explained, would make claims of improvement more credible.

No responsible utility can promise that every fault will disappear. Karachi can, however, demand fewer sustained interruptions, fewer hours without electricity, faster verified restoration, and fewer repeat failures.

The test of reform is what happens at the consumer’s socket. If those outcomes do not improve, spending announcements and assurances have yet to deliver the service residents need.
