Storing the Sun: Chinese Investment in Battery Energy Storage Systems and the Making of a Resilient, Affordable and Secure Power Sector in Pakistan

Abstract

Pakistan has become one of the world's largest importers of Chinese solar panels, and the rapid growth of distributed solar generation has shifted the country's power problem from a shortage of daytime energy to a shortage of flexible, dispatchable supply in the evening and a financial burden of idle thermal capacity. Battery energy storage systems (BESS) are increasingly seen as the technology that can bridge this gap. This qualitative, documentary and comparative study examines the scale and drivers of storage demand in Pakistan, the nature and limits of Chinese investment in the storage value chain, and the lessons that can be drawn from India, Chile and China itself. Drawing on regulatory determinations, multilateral project disclosures, think tank datasets, market surveys and peer reviewed literature, the paper finds that storage demand is already structural, with an estimated 7.6 GWh of batteries imported by the end of 2025, and that the National Electric Power Regulatory Authority (NEPRA) has now mandated colocated storage in the first renewable wheeling auction. Chinese firms dominate equipment supply and are moving towards assembly and manufacturing, but most announced projects remain at the memorandum stage. The paper argues that success depends less on access to cheap Chinese equipment than on three domestic conditions: bankable and performance based revenue mechanisms, enforceable safety and grid standards, and contract design that avoids repeating the capacity payment trap of earlier energy investments. It proposes a hybrid model that combines an Indian style tendered availability tariff, Chilean style solar plus storage hybridization, and Chinese equipment and finance under local content and quality safeguards.
