Empowering Energy Future: Unleashing the Potential of Gross Metering in Weak Distribution Grids: A Case Study of Pakistan

Gross metering in the power industry refers to the entire amount of electricity generated by a renewable energy system before it is used by the system owner/prosumer. This paper addresses gross metering deployment, benefits, problems, and prospective improvements in Pakistan's Distribution Companies (DISCOs), particularly Islamabad Electric Supply Company (IESCO), where import/export ratio (39%/61%) is totally disturbed amongst all counterparts. Given Pakistan's high renewable energy potential, gross metering could play a crucial role in improving energy security and fostering sustainable development. This paper assesses the current state of gross metering, net-metering and normal metering comparative analysis, looks at case studies, and suggests legislative and technical improvements. A case-study of Islamabad Electric Supply Company (IESCO) is presented with realistic data. The gross metering results in 31.434% reduction in revenue as compared to 60.1% reduction, when compared to net metering. The gross metering results in 47.62% improvement in revenue collection for the utility.
