ISLAMABAD — Across industrial estates in Karachi, Lahore, and Sialkot as well as residential sectors in Islamabad and Rawalpindi, the rapid installation of rooftop solar photovoltaic systems is fundamentally altering daytime electricity consumption on Pakistan's national grid.
Driven by steep global declines in solar module and lithium-iron-phosphate (LFP) battery prices over the past eighteen months, households and export-oriented factories have increasingly turned to captive solar generation to insulate themselves from high grid tariffs.
Power sector data reviewed by energy analysts shows that grid demand during peak daylight hours has flattened or declined in several urban distribution circles, even as evening peak demand remains tied to thermal and hydel generation. That divergence has sparked debate between power division officials concerned about fixed capacity payments and industrialists who argue that affordable energy is essential for export survival.
Independent energy researchers emphasize that distributed solar should be integrated through smarter bidirectional metering, grid-scale battery storage, and revised power purchase contracts rather than discouraging private clean-energy investment.
