Pakistan rooftop solar boom upends grid economics as power demand jumps 21%
Rooftop panels now supply all of Pakistan's new electricity demand, leaving grid operators with a falling revenue base.
Pakistan's electricity demand rose 21% in the two years to financial year 2025, yet grid generation actually fell 3%, a split that signals how quickly distributed solar has upended the country's power market.5 Rooftop panels, not the central grid, met all of the new demand during that period.5
For anyone holding Pakistani power-sector exposure or watching LNG import volumes into South Asia, the divergence carries real consequences. A grid that is shrinking while the country's appetite for electricity grows presents a different set of risks than one straining to keep up — stranded thermal capacity, weaker collection rates and a harder sell for new baseload plants.5
The price signal behind the shift is blunt. Electricity bills consumed up to a quarter of household income in parts of Pakistan before the solar wave, while summer temperatures pushed above 50°C (122°F), according to The Economist's profile of Muhammed Munir, a retired railway worker in Lahore who decided the power cuts and costs were no longer bearable.2 That combination turned rooftop solar from a luxury into a rational household investment.
Dave Jones, chief analyst at Ember, put the dynamic plainly: "Pakistan has a thirst for energy, and solar is providing it."5 The result is a two-tier market — one layer of households and businesses generating their own power, and another of grid assets serving a shrinking, and likely less creditworthy, customer base.
The implications for thermal generators are direct. If the grid is no longer capturing demand growth, then new gas-fired capacity or further LNG imports sit on a weakening foundation. The economics of baseload plants deteriorate when the highest-value customers migrate to self-generation and leave the grid to absorb the least flexible load.5
Pakistan's nuclear expansion plans — developed in partnership with China, which remains the country's primary nuclear technology supplier — now face a market where incremental electricity demand is being met by distributed solar rather than central-station power.3 A technical case for new baseload nuclear still exists, but the demand-side reality is migrating toward decentralized generation.
The water angle adds another dimension. South Asia's water politics have been roiling: Afghanistan's late-October 2025 decision to build dams on the Kabul river has rankled Pakistan, and a proposed dam elsewhere in the region carrying a price tag of $167bn would be the world's largest if completed to plan.1 Shrinking glaciers and erratic weather are making river flows less predictable for roughly 2 billion South Asians.1
Hydropower, Pakistan's traditional baseload complement to thermal plants, depends on those same rivers. The Economist's reporting notes that climate-driven variability is hitting river levels and water flows directly, complicating the calculus for any generation source tied to water availability.1 Solar needs no water to generate — a practical advantage in a region where water is becoming a strategic constraint.
The comparison with Bangladesh sharpens the picture. Bangladesh Bank data through December 2025 show loans disbursed to the energy efficiency sector reached Tk 319.31 billion, against only Tk 60.45 billion for renewables — a more than fivefold gap, with efficiency taking 41.4% of total green finance and renewable energy just 7.8%.4 In the October-December quarter of 2025 alone, only Tk 3.53 billion went to renewables against Tk 34.54 billion for efficiency.4 Pakistan's solar experience illustrates what Bangladesh's finance allocation is leaving on the table.
JKM front-month, the Asian LNG benchmark, was last marked at $20.91/MMBtu on 2026-08-06. European buyers watching Asian LNG competition will note that a continued shift toward distributed solar in South Asian markets reduces the import demand that would otherwise support spot volumes.
The unresolved risk is political. Letting rooftop solar keep cannibalizing grid demand undermines the revenue base that pays for existing thermal capacity and planned nuclear build-out, but throttling it via net-metering cuts or grid fees would hit households that invested in panels to escape punishing bills. Pakistan's policymakers have not yet announced a response. The 21% demand figure says the country needs more power; the 3% grid decline says the central system is not delivering it.5
