The project delivers large-scale renewable electricity for the nearby INEOS Inovyn chemical production site through a dedicated high-voltage connection. PerPetum delivered the project end-to-end, covering development, investment, construction and long-term operation. ### Project Overview HELIOS is one of the largest solar installations directly linked to an industrial production site in Belgium. With 60 MWp of installed photovoltaic capacity, the installation produces approximately 54 GWh of renewable electricity per year. The solar park is connected to the INEOS Inovyn production facilities via a dedicated high-voltage line, enabling large-scale renewable electricity supply for an energy-intensive industrial process. The project demonstrates how utility-scale solar generation can be integrated into industrial energy systems through dedicated infrastructure and long-term energy sourcing strategies. ### The Challenge Deliver a large-scale solar installation connected directly to an industrial production site while coordinating: - Grid connection infrastructure - Permitting and stakeholder alignment - Construction and commissioning within strict project timelines ### Our Solution A 60 MWp ground-mounted photovoltaic installation connected to the INEOS Inovyn production site through a 70 kV high-voltage line spanning approximately 1.6 km. The project was delivered under a Design | Build | Operate | Invest model with guarantees on power delivery, performance and commissioning schedule. The installation provides long-term renewable electricity supply integrated with the energy sourcing strategy of the industrial site. - 60 MWp ground-mounted photovoltaic installation - Dedicated 70kV high-voltage connection (1.6km) to the industrial site - Utility-scale solar integrated with industrial electricity demand - Long-term asset operation and performance management - Full lifecycle management: development, investment, EPC and O&M Delivered by PerPetum as a fully integrated development, investment, EPC and O&M engagement. ### Project highlights 60 MWp Total installed capacity 72 GWh Annual clean energy production 32,000 t CO₂ avoided per year ### Results & Impact HELIOS generates approximately 54,000 MWh of renewable electricity per year, supplying renewable power to the INEOS Inovyn production site in Jemeppe-sur-Sambre. Through a dedicated high-voltage connection, the installation integrates large-scale solar generation directly into the energy system of an energy-intensive industrial facility. The project contributes to the long-term supply of renewable electricity for industrial operations.
