Pakistan's Power Plan Locks Out Storage, Leaving the Grid Vulnerable to Peak Demand

Pakistan's National Electric Power Regulatory Authority (Nepra) approved the Integrated System Plan 2025, 35 on September 11, 2026, covering generation and transmission investment through the next decade^[1]. The decision came with a critical omission: Nepra rejected a proposed $900 million battery energy storage system (BESS) as unjustified, citing the lack of optimization studies, and excluded a K-Electric transmission line from the approved plan^[1]. The regulator's choice reveals how planning frameworks shape energy futures, and Pakistan's example mirrors institutional patterns now visible across South and Southeast Asia.

The plan itself is expansive: peak demand is projected to rise from 26,950 MW in 2025 to 35,521 MW by 2035, requiring 26,045 MW of new capacity^[1]. That is a 32 percent surge in peak load. The approved $47.13 billion generation plan and $10.65 billion transmission upgrades are meant to meet it^[1]. But the rejection of storage signals something harder to change than wires and turbines: the institutional assumption that generation capacity solves peak, and that storage is a luxury rather than a system necessity.

This is not a technical judgment. Nepra did not rule storage infeasible; it ruled it had never been run through the optimization model^[1]. In other words, the question was not asked. This is how institutional bias operates: not through explicit rejection of a technology, but through the prior decision not to model it. Meanwhile, Pakistan's distributed solar market, driven by punishing grid tariffs and gray-market panel imports, is now a quarter or more of the country's installed capacity, a bottom-up expansion that outran the national plan by years^{[background: Pakistan solar adoption precedent]}. Peak demand is collapsing during midday hours when rooftop and utility solar are at maximum, creating a ramp problem (the rate of demand rise in late afternoon) that conventional generation cannot track as quickly as a battery can. Storage is not optional in this grid; it is the missing tool.

The comparison abroad is instructive. Australia integrated rooftop solar at one in three houses, reaching nearly 14 GW of distributed capacity by 2023, by pairing upfront rebates with accredited-installer competition and retail product innovation around solar fleet management^{[background: Australia solar penetration and soft costs]}. Germany legalized plug-in balcony solar at 800W by registration rather than engineering review, and paired that flexibility with battery subsidies in several states, making battery ownership routine in high-solar households^{[background: German Balkonkraftwerk and battery support]}. Neither country suspended storage because a model had not been run. Pakistan's regulator has the authority to direct ISMO to model BESS in the next cycle; the institution chose not to push it yet.

The result is a plan that locks generation capacity into conventional sources for a decade, even as the grid's midday solar surplus and late-afternoon ramp become the defining operational problem. Battery prices have fallen below $100/kWh globally; Pakistan's cost of capital is higher, but so is the tariff pain driving solar adoption. A $900 million BESS investment at scale would cost far less per kilowatt-hour of capacity than the next 5 GW of fossil generation. Nepra's decision to exclude it does not make the problem disappear; it defers the choice to a crisis year when emergency battery procurement will cost three times more.
