Key Highlights

Pakistan has deployed close to 38 GW of solar within a decade and saved more than USD 12 billion in fossil fuel imports, yet this rapid buildout has outpaced grid flexibility and produced a pronounced duck curve along with PKR 46.39 billion in Partial Load Adjustment Charges in FY2025 and PKR 81 billion in curtailment losses between FY20 and FY25. The IGCEP currently treats storage only as a grid-support tool for frequency response and intermittency management and does not assess bulk energy shifting, renewable firming, or evolving load patterns from distributed solar and future electric vehicle uptake. This study quantifies Pakistan's Battery Energy Storage System requirement to 2045 and builds four commercial cases for its deployment, equipping planners, regulators, and investors with an evidence base to shape procurement and market design. The optimized pathway confirms BESS capacity must grow from 6.3 GW in 2030 to 15.2 GW by 2045, while commercial applications such as energy arbitrage, PLAC reduction at Bhikki, curtailment avoidance at Jamshoro, and solar paired with thermal energy storage for industrial firm capacity all deliver strong returns with IRRs reaching up to 16 percent and industrial power at USD 0.062 per kWh. These results give Pakistan clear visibility into the scale, timing, and location of its storage needs, and they justify shaping procurement, market design, and compensation for flexibility services in future capacity plans.
