Aperam Genk – Industrial Solar & Energy Storage for Steel Production
Decarbonisation that strengthens competitiveness
Aperam's stainless steel plant in Genk faced a dual challenge: structurally high electricity costs eroding margins and ambitious decarbonisation targets requiring action at scale. PerPetum delivered a fully integrated behind-the-meter energy hub, combining rooftop and ground-mounted solar, carport PV and 80+ EV charging points, without any upfront investment or operational burden for Aperam. A battery energy storage system (BESS) is under development at the site to add peak shaving capability and ancillary revenue streams.
Project Overview
In energy-intensive steel manufacturing, electricity represents a significant share of total production cost. Price volatility, rising grid tariffs and carbon exposure directly threaten competitiveness. Aperam needed a long-term energy strategy that locks in cost predictability, accelerates Scope 1 & 2 reduction, and keeps capital available for core operations, not energy infrastructure.
The Challenge
Protect high-volume steel production from electricity price swings, growing grid costs and tightening carbon regulation, while preserving CAPEX for core industrial investments and maintaining global competitiveness.
Our Solution
A tailor-made behind-the-meter ecosystem combining solar across rooftops, ground-mount and carports, orchestrated through advanced forecasting and day-ahead optimisation to maximise self-consumption. Battery storage is under development to unlock additional flexibility value and ancillary services.
- Rooftop solar across multiple factory buildings
- Ground-mounted PV on available site area
- Carport PV with integrated generation
- Battery energy storage (BESS) under development for peak shaving & flexibility
- 80+ EV charging points for future mobility
- Advanced energy management with day-ahead optimisation
All designed, financed, built and operated by PerPetum under an Energy-as-a-Service model, fully off-balance-sheet.
Project Highlights
Results & Impact
80 GWh of clean energy secured under a fixed-price structure, delivering long-term cost predictability and significant lifetime savings. A battery energy storage system is under development at the site, which will add peak shaving capability and ancillary revenue streams, further lowering Aperam's production costs and carbon footprint. The entire solution is delivered without balance sheet impact.
