Decentralized Solar vs Centralized Coal: Pakistan's Power Economics and the New Equation for Belt and Road Debt

Something quietly seismic has happened to Pakistan's national grid over the past few years. As rooftop solar panels and lithium batteries have flooded in, grid demand has begun to fall — and the coal-fired plants that once absorbed much of that demand now sit idle for much of the day. By August of this year, overdue payments to Chinese-backed coal plants had passed $1.5 billion; roughly $3.1 billion of project debt is stuck in coal assets, and at the Port Qasim plant alone about $300 million is overdue. A Bloomberg report published on Thursday said Islamabad and Beijing have begun talks on restructuring the debt around this crisis. To understand it, go back to the coal projects of the Belt and Road Initiative (BRI). Pakistan's power sector has long run on a single model: whether a plant runs or not, the producer is paid a fixed sum — the capacity payment. Dollar-denominated, and layered on top of fuel imports and distribution losses, these payments have kept pushing consumer tariffs upward. Meanwhile the central grid keeps supplying regardless, so supply stays mandatory where demand no longer exists. That gap is what has slowly hardened into a structural crisis. Solar rose precisely inside that gap. Facing high tariffs and unstable supply, ordinary Pakistanis and businesses began putting panels and batteries on their roofs, turning themselves from consumers into producers. The evidence is plain: battery imports jumped 150 percent to roughly $392 million. From factory owners to households, everyone seems to be walking toward a decentralized, self-reliant power structure. The shock landed on the coal plants. When grid demand falls, coal plants are run less — but the capacity-payment burden does not fall with it. Utilities paying for electricity they never generate see their finances deteriorate fast, in what many now call the utility death spiral. The first turn of that spiral is falling revenue, the second a mountain of overdue payments, and the last turn a higher tariff burden placed on consumers to clear it. There is an uncomfortable truth here. Pakistan's policymakers did not see this transition coming — they seemed to wake up to find demand had simply moved away. Institutional data from NEPRA and Ember paint the same picture: grid-based demand falling, solar generation rising. It was not chaos; it was a code I had to decode — a price signal that not everyone could read, but that consumers did. This is where a popular misconception needs breaking. Many want to frame the story as a triumph of green policy, but in reality it is not the product of any state environmental strategy; it is the product of raw economic necessity. No one ordered the coal plants shut — consumers did the math and left, because the gap between the grid bill and the cost of solar is easy to see. That is why the point matters: demand loss is hitting coal not politically, but through the market. And when coal assets fall out of use, they become stranded assets — investment that cannot earn. That stranded-investment liability now sits at the center of the Islamabad-Beijing talks. Islamabad wants extended repayment schedules and refinancing; Beijing faces the question of whether to extend maturities or accept a partial haircut, meaning some debt forgiveness. Repurposing assets — putting coal plants to other uses — is also on the table. But a caution is warranted here: mapping sovereign-debt arithmetic onto club-finance rules would mislead, because these are two different worlds with two different logics. Still, the underlying point is the same — an asset that cannot earn becomes a liability. The blockchain idea becomes relevant for a deeper reason. When power generation spreads across rooftops, the system effectively decentralizes — much as blockchain uses a distributed ledger instead of a central book. In several South Asian markets, including Pakistan, trials have already begun in peer-to-peer electricity trading, tokenized carbon credits, and settling capacity payments through smart contracts. These trials are small, but the direction is significant: if control over grid demand shifts into consumers' hands, the very foundation of a centralized power economy comes into question. At the political level, Pakistan's Energy Minister Awais Leghari is speaking of balancing supply and bills. The reality on the ground says otherwise. Factory owner Zaheer Allana moved to solar to cut his production costs; clean-tech importer Muhammad Mujahid is selling more batteries and solar equipment; and academic Kevin Gallagher is watching the structural risk inside BRI, where the borrowing country's own power demand is shifting. Four different voices, four sides of the same truth. When I sit down to reconcile the numbers in the feed against the figures in the report, a pattern becomes clear: the problem is not the quality of coal, it is the structure. A guaranteed-income promise like the capacity payment cannot stop consumers from walking away. The solar surge, cross-border equipment imports, and the weight of foreign debt have together put the future of Chinese-backed coal plants in question. Looking ahead, three signals deserve watching. First, whether the Islamabad-Beijing talks end in a maturity extension or a genuine restructuring will decide the fate of the coal plants. Second, if battery and solar imports keep moving at this pace, the floor under grid demand will fall further. And third, if peer-to-peer and blockchain-based energy trading scale up, the real question is whether the centralized capacity-payment model can survive. The question is no longer whether coal will be shut down; it is whether a consumer who has become a producer can be pulled back.
