Pakistan's Solar Boom Pressures Chinese-Backed Coal Plants and Complicates Debt Restructuring

Pakistan's Solar Boom Pressures Chinese-Backed Coal Plants and Complicates Debt Restructuring After the owner of a Pakistani textile factory, Zaheer Allana, installed rooftop solar panels and batteries, his monthly electricity bill fell. But the real change happened elsewhere — the factory's power demand from the national grid dropped to almost zero. Decisions like Allana's, multiplied across thousands of consumers, are now reshaping Pakistan's energy geography. A Bloomberg analysis published on Thursday shows the ripple reaching the financing of Chinese-backed coal-fired power plants — and from there, complicating Islamabad and Beijing's talks on sovereign debt restructuring. Data from 2026 shows the new reality cannot be squared with the old contract ledger. As solar panel prices fell in Pakistan, distributed generation spread rapidly. Panels went up on factory, home and shop roofs, joined by battery storage. A clear measure of this shift is battery imports, which rose 150 percent to about 392 million dollars. Analysts say this is largely a wave of Chinese solar and battery exports that reaches countries like Pakistan and dampens local grid demand. Traders such as clean-tech importer Muhammad Mujahid sit at the front line of this transition. Pakistan's power sector has long suffered under circular debt and subsidy pressure. As the gap between consumer tariffs and generation costs widens, the subsidy burden on the government grows. In such conditions, solar has become a private solution — those who can afford it generate their own power. But that further shrinks the revenue of utilities that depend on those who cannot. Here lies the complication: under Pakistan's power purchase agreements, coal plants must be paid a fixed capacity payment regardless of consumer demand. In other words, even as grid demand falls, the utility's payments do not. This is where the so-called "death spiral" forms. As consumers shift to solar, grid sales fall, but the utility must still make fixed payments to coal plants. So bills rise, and more consumers move to solar — the cycle continues. By August 2026, Pakistan's overdue payments to Chinese coal plants exceeded 1.5 billion dollars. At Port Qasim alone the arrears are about 300 million dollars, while total project debt on coal assets is about 3.1 billion dollars. These figures are a direct sovereign debt burden. Coal plants were built relying on Chinese loans and investment under the Belt and Road Initiative. Repayment of these project loans depends on revenue from electricity sold by the plants. But when grid demand falls, sales fall too — while the loan instalments remain fixed. As a result, utilities run short of cash and arrears pile up. The seriousness is visible in the comments of Energy Minister Awais Leghari and in assessments by industry analysts. Data from NEPRA and Ember point the same way: record solar capacity is being added, even as the power sector's financial stability weakens. Experts such as political-economy researcher Kevin Gallagher have shown that this kind of risk has emerged in many countries under Belt and Road debt structures. The open question is what future awaits the coal plants China invested in — and who will carry that future. If a country generates power on its own rooftops, will it keep paying indefinitely for the idle capacity of coal plants? From the outside, many read this event as a simple "green energy success" — the assumption that solar means a win for the environment and coal means defeat. Pakistan's reality is more complex. Here solar's spread is not the result of a planned policy transition; it came under the pressure of private and business decisions, landing on a fragile utility-finance system. Those who set solar simply against coal miss the real question — the fixed payments in power purchase agreements and the structure of sovereign debt. Solar is no simple hero here, nor coal a simple villain; the question is one of investment, contracts and political economy. Pakistan is not alone — power-sector transitions worldwide show that technological change outpaces financing structures, and that gap breeds mismatch. A further question of fairness is emerging. Those who can install rooftop solar are mainly the affluent and big business. The grid's fixed costs then fall on ordinary consumers. So solar's spread is environmentally friendly on one side and raises a distributional-fairness question on the other. This situation is not Pakistan's alone. Similar pressure is building in many South Asian countries and even in parts of Europe and Africa — where renewable costs are falling while the fixed payments of old fossil plants become a burden. China plays a dual role in this shift — supplier of cheap solar and batteries on one side, lender to coal plants on the other. This duality is creating a new geopolitical equation. Debt restructuring offers several paths. One is extending the repayment period to ease the immediate squeeze. Another is refinancing — swapping old debt on new terms. A third is repurposing assets, that is, putting coal plants to other use or shutting them down. Every path requires the consent of Chinese lenders, and that is where the real bargaining lies. Islamabad is now discussing proposals with Beijing for extending repayment, refinancing or asset repurposing. The question is whether Chinese lenders will grant more time, or accept a partial haircut. That decision will cast a shadow not only on Pakistan's power bills but on the Belt and Road Initiative's overall financing model. Looking ahead, however bright the solar panels on Pakistan's rooftops, the contract ledger is still running on old arithmetic — and the day that arithmetic is settled will decide who wins this transition and who bears the cost.
