Wheeling hybrid energy system for industries

Worldwide most of the energy is provided through conventional energy sources such as thermal, hydro, and nuclear. Industries suffer from serious energy crisis nearly decade; therefore, it is essential to integrate them with other renewable energy resources. This paper presents a cost effective solution, Wheeling 36 MW Grid-connected Hybrid Energy System for Gadoon industrial load in Pakistan. The system has been implemented in HOMER (Hybrid Optimization Model for Electric Renewables) considering five cases for analysis, in which Grid-Hydro-PV-Wind based system, Grid-Hydro based system and Grid based system are discussed, in detail. Since hydro power is already installed, it reduces 26.89% cost of energy and grid purchase to 63.32%. Moreover, the Grid-Hydro-PV-Wind based system is the most economical of all owing to 42.85% reduction in electrical tariff and it also reduces the grid energy consumption to 33.98% as compared to existing Grid based system. The proposed system yields 66% high renewable fraction. We also hope that the nation's dependence on fossil fuels and its economic impact will be made lower. Thus, we expect its contribution towards the progress and growth of industrial sector in Pakistan.
