Pakistan's Solar Boom Breaks the Grid Business Model, Triggering a Rollback

In June 2024, Pakistan's grid demanded 8.66 percent less electricity than it did a year earlier^[1]. The cause was not recession or conservation: it was rooftop solar. In roughly two years, Pakistanis installed approximately 27 gigawatts of distributed solar, roughly equal to all the coal, gas, and oil plants ever built in the country^[9], lifting distributed solar toward a quarter of national electricity supply. Electricity sales at the country's largest distribution company fell 16 percent in April alone^[1]. The grid was not broken by physics; it was broken by arithmetic.

The mechanism is not mysterious. Pakistan's power sector has accumulated a "circular debt" of PKR 2.4 trillion (about $8.6 billion USD)^[4], the gap between what distribution companies collect and what they owe generators. Of the average household bill, 30 to 35 percent now consists of non-energy financial adjustments, charges for inefficiency and debt repayment^[4]. As grid sales fell and that fixed cost had to be spread across fewer remaining customers, the burden per unit rose. By the end of 2024, electricity prices in Pakistan had increased by nearly 155 percent over a decade^[8]. That wall of cost met Chinese solar panels available at a global floor price, and rational consumers made a choice: buy panels, stop buying grid power, stop paying the cost of other people's debt.

The government's response was to nationalize the loss by cutting the buyback rate. In December 2025, Pakistan's Ministry of Energy approved a shift from "net metering" (where excess solar generation was credited at retail rates) to "net billing" (a fixed compensation of Rs11 (about $0.13 USD) per unit, about 58 percent of the previous rate)^[7], and shortened solar agreements from indefinite to five years^[7]. The stated aim was to "align solar incentives with evolving market conditions," but the mechanism is clear: make solar a worse deal, discourage further installation, preserve grid sales and the capacity-payment revenue model that depends on them.

This is the pattern everywhere the global South installs distributed solar faster than incumbent institutions can control it. Vietnam ran an earlier version: a generous feed-in tariff triggered a rooftop explosion of roughly 9 gigawatts added in 2020 alone, then policy whiplash as the government cut the tariff, introduced curtailment, and retroactively changed rules^[4]. Africa's minigrid companies are learning the same lesson: install faster than regulation can stabilize it, and regulation will stabilize against you. Pakistan is different only in scale and speed. In two years, consumers bet on panels rather than wait for the grid to become affordable, and they are now being penalized for winning that bet.

For the United States, the lesson is that this is not inevitable. Australia achieved rooftop penetration of roughly one in three freestanding homes, the world's highest, at installed costs near A$1.00 to 1.30 per watt (about $0.65 to $0.90 USD) versus $2.50 to $3.50 per watt in the US, through a policy design that expected adoption and built consent into the grid architecture from the start^{[research library]}. The US has chosen the Pakistan path: fight distributed solar at every stage (interconnection delays, engineering reviews, roof-to-meter soft costs that are really regulatory cost), then when installations accelerate despite the headwind, introduce tariff cuts and time limits as a corrective. Pakistan did it faster because the tariff pain was more acute; the US is doing it slower because it can afford to. But the direction and the mechanism are the same.

The concrete alternative is to price the grid correctly upfront. Pakistan's electricity tariff embeds PKR 2 (about $0.01 USD) trillion in annual capacity payments alone^[4], the cost of plants run part-time or mothballed, contracted under take-or-pay agreements that made sense when growth was assumed. That is not solar's fault; it is the grid's. The fix is to restructure that cost to fall on grid users who choose the grid, not on people who install solar and stop paying it. France shifted that mechanism by renationalizing EDF in 2023 and using a tariff shield to prevent disconnection and maintain affordability; Spain, Belgium, and Portugal run social tariffs that protect vulnerable households from the cost of other people's take-or-pay deals^{[research library]}. Pakistan could cap grid tariffs for essential use and require capacity payments to be paid by commercial load or recovered through a small per-kilowatt monthly connection fee on all grid-connected homes, whether they use it or not, rather than per-kilowatt-hour charges that punish the people who cannot afford alternatives. The people who own the debt should own the solution. Instead, the government has chosen to make solar a worse deal, and the next phase of the story is already written: faster gray-market imports, installation by unaccredited technicians to avoid registration, and a grid left with even fewer customers bearing the same debt.
