Pakistan's transition from net-metering to net-billing for rooftop solar has exposed deep structural fault lines in the country's power sector, raising fears that rising tariffs, declining grid demand and policy uncertainty could accelerate a gradual unravelling of the national electricity system.
At the heart of the debate lies a fundamental tension over who pays for the grid. Under the previous regime, solar users could offset exported electricity against consumption at retail rates that included not just energy costs but also capacity payments, system losses and subsidies. The revised framework compensates exports at a much lower rate, limited largely to the energy component.
For regulators, this adjustment seeks to protect an already strained system. As higher-paying urban consumers shifted to rooftop solar, distribution companies faced shrinking revenues while fixed obligations remained intact. Without reform, the burden risked shifting to non-solar users, intensifying distortions.
For consumers and investors, however, the change alters the economics of solar adoption. Payback periods are lengthened, and the emphasis shifts from eliminating bills to maximising self-consumption. This recalibration may slow new investment, particularly if policy signals appear abrupt or inconsistent.
The stakes extend beyond rooftop economics. Pakistan's electricity sector is grappling with a paradox: modest economic expansion alongside stagnant or declining grid demand. Over recent years, output has edged upward, yet electricity consumption from the national grid has failed to keep pace-a divergence rarely seen in developing economies.
This phenomenon reflects deeper stress. Industrial tariffs, ranging between 15 and 17 US cents per kilowatt-hour, rank among the highest in competing economies. These elevated costs stem not only from generation expenses but also from structural burdens, including nearly Rs2 trillion in annual capacity payments, circular debt and high system losses.
As prices rise, demand weakens. Firms scale back operations, delay investment or shift to captive power. Households reduce usage or seek alternatives. This feedback loop-where falling consumption drives higher tariffs-has created what economists describe as a 'utility death spiral'.
Distributed solar has emerged as both symptom and solution. Pakistan has rapidly expanded decentralised capacity, with an estimated 15 to 18 gigawatts installed, much of it outside formal grid arrangements. Around 450,000 households are connected through net-metering systems, while millions more rely on standalone installations.
This shift has provided resilience. Solar systems have enabled businesses to continue operations, reduced dependence on imported fuels and mobilised private investment in energy infrastructure. In many rural and peri-urban areas, where power outages are frequent, solar serves as essential reliability rather than a financial arbitrage tool.
Yet the same trend introduces new risks. As the gap between export compensation and grid purchase prices widens, consumers may increasingly invest in battery storage to reduce reliance on the grid. Such behaviour could erode the revenue base further, concentrating costs on a shrinking pool of users.
Policymakers face a delicate balancing act. They must ensure financial sustainability, maintain fairness among consumers and preserve incentives for clean energy investment. Abrupt restrictions risk undermining confidence and accelerating off-grid migration, while overly generous incentives could distort cost allocation.
Officials insist the reforms are not intended to halt solar adoption but to correct imbalances. Falling global costs-solar generation now below three US cents per unit in some cases-have rendered earlier buyback rates disproportionately high. Aligning compensation with actual costs is seen as necessary to prevent cross-subsidisation.
At the same time, the transition raises broader questions about equity. While most consumers-over 90 percent-remain unaffected by the changes, concerns persist that poorly designed reforms could limit access to renewable energy for lower-income households. Provincial initiatives, including subsidised solar schemes, highlight the potential for targeted interventions to address energy poverty.
The underlying challenge, however, lies in the architecture of the power sector itself. Imported fuel dependence, mounting circular debt and rigid capacity payments continue to distort pricing. Adjustments to rooftop solar policy alone cannot resolve these systemic issues.
Analysts argue that the solution lies in integration rather than restriction. A modern electricity system would combine centralised generation with decentralised sources, supported by storage, digital monitoring and flexible pricing. Transparent tariffs, gradual policy transitions and investment in grid infrastructure are seen as essential to this shift.
Pakistan's energy transition is thus at an inflection point. Distributed solar has already transformed the landscape, reduced shortages and expanding access. The question now is whether policy can adapt to this reality.
If managed carefully, the shift to net-billing could support a more sustainable system. If mishandled, it risks accelerating fragmentation, weakening investor confidence and deepening the very imbalances it seeks to correct.
