i4energy undertook the design, development and commissioning of an integrated monitoring and control system for three PPCs, covering 82 photovoltaic power plants with a total installed capacity of 54 MW, connected to the Assiros High Voltage Substation.
The project aims to optimize energy production monitoring and centralized control by the System Operator, ensuring the reliable, stable and efficient operation of the entire portfolio.
Leveraging across®, i4energy’s advanced digital energy platform, the company designed and implemented a tailor-made solution fully adapted to the technical and operational requirements of the project.
The deployed system consists of three local gate controllers (Slave Power Plant Controllers – SPPCs) and 82 remote terminal units (RTUs – across®Edge) installed across multiple PV parks. This architecture ensures full compliance with Central Controller commands and Grid Operator requirements, while enabling optimal energy production management, grid stability, and operational flexibility.
The local controllers developed by i4energy support redundant architectures across critical subsystems, maximizing system availability and ensuring uninterrupted operation. The overall system architecture has been designed with future scalability and seamless integration in mind.
Scope of i4energy’s deliverables:
- Installation of all required hardware and software
- System commissioning
- Initial configuration of the across® software platform
- across® software maintenance services
- Hardware maintenance services
- Customer training
Commenting on the project, Mr. K. Chrysikopoulos, Chief Solutions Officer of i4energy, stated:
“We designed a three-layer architecture that interconnects individual units across multiple photovoltaic parks with the High Voltage Substation, which in turn communicates with the Central System Operator. This vertically integrated digital structure ensures the efficient management of the substation’s 54 MW capacity and its seamless integration into the Grid. The project is a clear example of digital transformation shaping the future of energy management
