KARACHI POWER
Karachi is more than Pakistan's largest city; it is the country's economic engine. Contributing an estimated 20-25 per cent of national GDP, hosting the largest industrial base and serving as the primary gateway for trade and commerce, Karachi's competitiveness is intrinsically linked to the reliability, affordability and sustainability of its energy supply.
Given Karachi's economic significance, conversations about the city's power sector deserve to be grounded in evidence and viewed through a holistic lens. Electricity affordability and reliability are outcomes of an interconnected system encompassing fuel availability, generation planning, transmission infrastructure, distribution performance, regulatory oversight and consumer behaviour. Looking at one component without considering the other risks oversimplifies a far more complex reality.
Pakistan's energy sector has undergone significant transformation over the past two decades, and Karachi's experience via its utility, K-Electric, offers important lessons in both progress and the challenges that remain.
One area where data provides a valuable perspective is network efficiency. According to Nepra's State of Industry (SoI) reports, transmission and distribution losses in Karachi have declined from over 34 per cent at the time of privatisation to approximately 15.3 per cent today. Recovery rates have improved to around 92 per cent, while nearly 70 per cent of KE's network is now exempt from load-shedding compared to only 6.6 per cent at the time of privatisation. Industrial customers continue to remain loadshedding-free, helping support economic activity in Pakistan's commercial capital.
Importantly, the latest SoI data also demonstrates that while losses remain a challenge across Pakistan's power sector, KE's loss levels today are materially lower than those of several public-sector distribution companies. This does not suggest that the challenge has been fully resolved, but it does indicate that sector performance should be assessed through long-term trends rather than isolated figures. Moreover, KE is the only DISCO whose actual T&D loss varies by less than 0.5 per cent from its allowed T&D target. All other DISCOs, cumulatively, missed their average target by over 6.0 per cent.
These improvements reflect the impact of sustained investments in network modernisation, technology deployment and infrastructure upgrades. According to World Bank assessments, KE's privatisation has generated approximately Rs900 billion in savings for consumers and the government.
At the same time, electricity affordability is determined by far more than distribution efficiency alone. Across the world, access to lower-cost indigenous energy resources remains one of the strongest determinants of electricity prices. Hydropower, nuclear energy and renewable resources typically provide greater price stability than imported fuels, shielding consumers from international commodity volatility and exchange rate fluctuations.
This broader context is particularly relevant when examining Karachi's energy landscape. Despite hosting Pakistan's nuclear generation facilities, the city does not directly benefit from nuclear power as a dedicated local energy source. These realities help explain why electricity affordability must be viewed across the entire value chain.
Optimising Karachi's energy pricing requires a more integrated approach to grid integration, allowing the commercial hub to seamlessly leverage low-cost base-load generation, such as the strategic nuclear assets located within its vicinity, through a modernised national wheeling and allocation framework.

The importance of generation planning is becoming even more pronounced as Pakistan accelerates its energy transition. Under the Indicative Generation Capacity Expansion Plan (IGCEP), the country has committed to increasing the share of renewable energy within the generation mix as part of a least-cost pathway towards future energy security.
Recent competitive bidding exercises by KE have demonstrated the economic viability of this approach. Projects identified under this framework, including the 220MW Dhabeji wind-solar hybrid project and solar projects planned in Sindh and Balochistan, have achieved among the lowest renewable energy tariffs recorded in Pakistan, with bids as low as $3.09 cents per unit, approximately Rs9.8 per unit. However, unlocking rapid renewable deployment relies on deep institutional alignment, where streamlined regulatory approvals, expedited transmission planning and harmonised national policies work in tandem to de-risk private capital investments.
The transmission system represents another important piece of the puzzle. Historically, Karachi's ability to import electricity from the national grid remained constrained by transmission limitations. Investments such as the Karachi Kanupp Interconnection (KKI) have significantly enhanced interconnection capacity, up to 2000MW, enabling greater imports from the national system and strengthening supply reliability.
Nevertheless, Karachi’s operational realities continue to affect electricity networks nationwide. Power theft, illegal connections, encroachments on utility infrastructure and unauthorised interference with networks impose substantial technical and financial costs on the system. These challenges continue to contribute to inefficiencies across the sector and ultimately affect paying consumers. While critics cite minor target variances, Nepra’s SOI reports consistently show that urban utility management under high-inflationary cycles faces systemic headwinds. Aggressive enforcement against theft must be matched by civic and law-enforcement alignment, making grid-loss reduction a shared governance challenge, not a single corporate failure.
The migration of high-paying consumers to net-metered rooftop solar is a national phenomenon highlighted in recent regulatory reviews. This systemic 'death spiral' forces fixed grid costs onto lower-income consumers. The solution isn't institutional blame; it is an urgent national overhaul of the tariff design to protect the base of the pyramid, which is already underway at the policy level.
Climate change further reinforces the need for a comprehensive approach. Pakistan remains among the countries most vulnerable to climate-related risks, while Karachi has experienced rising temperatures, more frequent heatwaves and growing cooling demand. Peak electricity demand in the city has crossed 3,500MW in recent years and is expected to continue increasing.
For Pakistan's economic capital, the stakes are especially high. Reliable and affordable energy is not simply a utility issue; it is a competitiveness issue. It affects industrial productivity, export competitiveness, investment decisions and job creation. Ensuring that Karachi remains a driver of national growth will require continued focus on efficiency improvements, diversified fuel sources, renewable integration, transmission expansion and infrastructure protection.
The debate, therefore, should move beyond
isolated metrics or individual stakeholders and instead focus on how Pakistan can build a resilient, affordable and sustainable energy ecosystem for the future. The data shows that meaningful progress has been achieved, but also highlights the scale of the work that remains. Achieving the next phase of transformation will require collaboration, long-term planning and a commitment to evidence-based policymaking.
For a city that powers a significant share of Pakistan's economy, nothing less should suffice.
