Solar Imports and the Grid: Pakistan's Unmanaged Energy Transition

Something unusual is happening in Pakistan’s power sector: a genuine energy transition is underway, and the state is largely a spectator. Driven by collapsing panel prices, punishing grid tariffs, and chronic unreliability, households, farmers, and businesses have imported and installed rooftop and off-grid solar at a remarkable pace. It is one of the fastest bottom-up solar adoptions anywhere. It is also creating problems no one planned for.

The logic of defection. For a growing share of consumers, the calculation is simple. Grid electricity is expensive — loaded with the cost of capacity payments, transmission losses, theft, and currency-driven fuel costs — and unreliable. Solar plus batteries is increasingly cheaper and more dependable. So those who can afford to leave, leave, at least partially.

The death-spiral risk. Here is the structural danger. Pakistan’s grid carries enormous fixed costs, including capacity payments owed to power producers whether or not their electricity is used. As wealthier, higher-consuming customers defect to solar, those fixed costs are spread across a shrinking base of remaining users — pushing their tariffs higher, prompting more defection. This is the classic utility “death spiral,” and Pakistan is closer to it than most.

The circular-debt overhang. All of this sits on top of an unresolved circular debt of well over a trillion rupees — the chain of unpaid obligations running through generators, distributors, and the government. The solar boom does not cause the circular debt, but by eroding the revenue base it makes the existing arithmetic harder, and it complicates the tariff rationalisation the IMF program demands.

The policy bind. Islamabad is caught between objectives. It wants the climate and import-substitution benefits of solar. It needs grid revenue to service its power-sector obligations and meet fiscal targets. Moves to revise net-metering terms — reducing what rooftop owners are paid for exported power — reflect that bind, but risk penalising exactly the clean-energy adoption the country needs.

The takeaway. Pakistan’s transition is real but unmanaged. The opportunity is a cheaper, cleaner, more resilient energy base. The risk is a two-tier system: those who can self-generate, and a hollowed-out grid serving those who cannot. How the state manages tariffs, net metering, and circular debt over the next two years will decide which outcome wins.
