Batteries reshaping energy landscape
The growing adoption of battery energy storage systems (BESS) in Pakistan is set to reshape the energy landscape — enabling a more decentralised and consumer-centric system, even as it poses significant challenges to the existing grid infrastructure.
This was highlighted in a report by the Institute for Energy Economics and Financial Analysis (IEEFA), titled “Battery Storage and the Future of Pakistan’s Electricity Grid”. According to the report, the adoption of BESS is being driven by both off-grid and on-grid solar photovoltaic (PV) installations. Pakistan imported 27.6 gigawatts of solar PV modules between FY19 and FY24, with an additional 5.2GW imported in the first half of FY25.
However, it is estimated that only half of the total imported capacity is currently installed across the country, and at least 11.5GW of this capacity exists off-grid. “It is unlikely that all rooftop and captive solar consumers will adopt battery storage systems because of the high upfront costs,” said the report.
If all existing net metering capacity were paired with equal-sized battery storage systems, it could reduce annual electricity demand from the grid by 1.5 terawatt-hours (TWh) or 1.1 per cent of the country’s demand.
Similarly, commercial enterprises like office spaces, which operate from 9am to 5pm, may not require battery storage at night. Assuming a conservative estimate where only 25pc of the energy produced by the imported solar panel capacity is stored, annual grid demand could be reduced by 11.5TWh, or 8.4pc of Pakistan’s actual demand.
The convergence of rising energy prices and falling costs for distributed energy resources (DER), such as rooftop solar PV systems and BESS, have encouraged consumers to adopt decentralised energy solutions, reducing reliance on the grid and energy costs. “Pakistan imported an estimated 1.25 gigawatt-hours of lithium-ion battery packs in 2024 and another 400 megawatt-hours in the first two months of 2025, a trend that is likely to continue,” said the report.

“This accounts for around 4.7pc of that year’s 25.6GW annual peak demand. Based on a daily charging-discharging cycle, installing the entire 1.25GWh of battery storage could mean a yearly deduction of 438GWh of energy demand from the grid,” said the report.
