Hera Group: efficiency and real-time control

WinCC OA: The Digital Heart of Infrastructure
Choosing Siemens WinCC OA allowed the creation of a cutting-edge remote control center in Forlì for gas, water, and district heating. This platform goes beyond traditional SCADA by offering modularity tailored to utility needs. Its architecture enables the Hera team to customize complex logic, ensuring granular and reliable 24/7 supervision over a network exceeding 50,000 km.
Integrated Management of 11,000 Plants
Adopting a hardware-agnostic software solution transformed operational complexity into a competitive advantage. Today, the system manages treatment plants and over 40,000 electronic waste bins under a single digital direction. WinCC OA’s ability to communicate with diverse vendors ensures smooth network expansion while maintaining high safety and sustainability standards.
