Techno-Economic Assessment of Net Energy Metering Implementation for Rooftop Solar PV in a Commercial Building in Bangladesh

Abstract

Net Energy Metering (NEM) involves to a mechanism that permits consumers to interconnect their distributed generation systems to the power grid network. NEM allows utility and consumer to mount a bi-directional meter to measure power flow in two directions- one from utility to consumer (import) and another from consumer to utility (export). The consumer’s monthly consumption bill will be calculated based on the net energy measured by the meter i.e. energy drawn from the distribution grid minus the energy delivered to the distribution grid over the stated billing cycle. This study assesses the technical and economic potential and feasibility of net metering system implementation for a rooftop Solar Photovoltaic (PV) in a commercial building. It also analyzes the environmental impact reduction by implementing such renewable energy utilization project.
