Design and Optimization of a Grid-Connected Hybrid PV/Wind/Battery System to Enhance Energy Efficiency in the Moroccan Textile Sector

Energy demand in Morocco has been growing steadily for years, and the textile industry sits at the heart of this challenge: it is one of the largest industrial electricity consumers in the country, yet still almost entirely dependent on a grid fed by imported fossil fuels. This paper presents a case study based on real consumption data from a Moroccan textile facility located in Casablanca, where we investigated how a grid-connected hybrid system combining rooftop solar PV, a wind turbine, and lithium-ion battery storage could cover the factory's full electricity demand. The system was modeled using two complementary tools: PVsyst for the detailed photovoltaic simulation and HOMER Pro for the overall hybrid optimization, where five energy scenarios were built and compared. The best-performing configuration is a 4,698 kWp PV array, one 800 kW Enercon E-53 wind turbine, and a battery storage system of 3,000 MWh total capacity, which achieves a renewable energy fraction of 94%, reduces grid purchases to just 706 MWh per year, and cuts CO 2 emissions from 7,517 down to 446 tons annually, a reduction of approximately 94%. These results confirm that hybrid renewable energy systems are technically viable for energy-intensive industries in Morocco and offer a clear and replicable path towards industrial decarbonization, in line with the country's national energy goals for 2030.
