Jhimpir-Gharo Wind: Megawatts Without Wires Become NPMV Invoices

The Gharo-Jhimpir wind corridor in Thatta and Jamshoro is Pakistan's proven commercial wind province. By late 2024, thirty-six wind power plants with a combined capacity of around 1,845 megawatts had been installed there between 2013 and 2022 under Renewable Energy Policy 2006 pathways. Dawn's September 2024 field reporting made the operational contradiction plain: a corridor that can supply on the order of 1,800 MW in strong summer conditions was being instructed to curtail toward roughly 1,200 MW as part of a southern generation stack of about 4,500 to 4,800 MW from coal, nuclear and renewables.

Turbines that look like a clean-energy success story from the motorway sit idle for reasons that are mostly wires and dispatch, not resource. Wind is a few percent of national capacity but a geographically correlated fleet. When the offtaker cannot take available energy for reasons defined in the energy purchase agreement, NPMV compensation is owed. Sector analyses covering FY2024 have quantified wind curtailment on the order of 1,337 gigawatt-hours, with NPMV-related loss reported around Rs 40 billion and replacement-generation costs adding a further Rs 22.73 billion in one renewables-focused decoding of the power purchase price.

Plant owners described incomplete settlement for energy that did reach the grid, with billed amounts accumulating at the Central Power Purchasing Agency and delayed-interest provisions going unpaid. Jhimpir-II 220/132 kV strengthening was energised earlier in the decade to support the Jhimpir cluster. Poorly sequenced capacity additions in the south, including wind projects approved when evacuation was already tight, turned resource abundance into a congestion externality. Modern bids need site-specific met masts, lidar campaigns, and wake-loss models, not only atlas averages from earlier decades.

Battery storage sited in the south is part of the same conversation. Storage cannot substitute for missing 500 kV transfer capacity, but it can absorb midday or high-wind surplus locally and reduce some instruction-to-curtail events when the constraint is local rather than corridor-wide. Community relations in Thatta and Jamshoro, land-lease fairness, and local hiring affect whether additional gigawatts can be sited even when wires improve.
