Empowering Greece’s Renewable Grid: Eunice Energy Group & Revolution Pi

Challenge
Scalable and Reliable Grid Integration
With the rapid expansion of decentralized photovoltaic (PV) systems, grid operators like HEDNO (Hellenic Electricity Distribution Network Operator) face increasing pressure to ensure real-time monitoring, operational visibility, and grid stability. For Eunice, which operates a portfolio of PV and wind farms across Greece, the challenge was clear: to implement a robust, compact, and scalable industrial solution that could integrate seamlessly into HEDNO’s existing SCADA/DMS systems – and do so across multiple sites with varying technical requirements.
Headquartered in Athens, Eunice Energy Group is a leading developer, owner, and operator of renewable energy infrastructure in Greece. With a forward-looking R&D division and a strong presence in wind and solar power generation, Eunice has consistently been at the forefront of innovation in clean energy and smart grid technologies and evaluates opportunities to enter new market in the IoT sector. The company’s mission to decarbonize the energy mix goes hand in hand with digital transformation, making it an ideal early adopter of advanced industrial automation platforms like Revolution Pi.
Solution
Revolution Pi as a Central Communication Hub
To meet its operational needs, Eunice selected Revolution Pi – an open, modular, and industrial-grade system – as the core communication and control interface between its PV plants and HEDNO’s grid infrastructure.
By bridging the gap between power production and centralized grid management, Revolution Pi enabled Eunice to establish secure, real-time control over its renewable energy assets – optimizing responsiveness and grid stability.
Implementation
Eunice deployed the solution across multiple sites, incorporating Remote Terminal Units (RTUs), PLCs, and Power Plant Controllers (PPCs) into a harmonized platform. The RevPi Connect now functions as the processing core for operational data, while the RevPi DIO ensures accurate signal acquisition, even under harsh environmental conditions typical of PV installations.
A secure router facilitates stable two-way communication with HEDNO’s systems, enabling:
- Real-time adjustment of power feed-in
- Swift response to grid commands
- Detailed monitoring of plant performance
Technologies Used:
- RevPi Connect: Acts as the main control unit, collecting real-time data on energy production, frequency, and system status, and executing control commands from grid operators or aggregators.
- RevPi DIO: Ensures high-precision acquisition and processing of digital signals for switching actions and fault detection.
- RS485 & Ethernet: Enable robust communication with field devices and secure integration with the SCADA/DMS system.
“With Revolution Pi, we’ve established a reliable foundation for intelligent control across our renewable energy portfolio. Its seamless integration with grid infrastructure enhances stability while optimizing our internal operations. We look forward to expanding this solution to future projects.”

Results & Outlook
Scalable Control with Real Impact
The collaboration has already led to notable increases in operational efficiency, faster response to grid fluctuations, and improved coordination with the national operator. For Eunice, this integration represents more than just a technical upgrade. It’s a strategic enabler of the company’s broader vision for energy autonomy and grid resilience.
Crucially, the modular nature of the Revolution Pi system allows Eunice to scale effortlessly, connecting new renewable assets and adding functionalities as demands evolve.
Expanding the Partnership
Building on this success, Eunice plans to expand the deployment of Revolution Pi across upcoming utility-scale projects, as well as explore its potential in the emerging field of energy storage and IoT applications.
Technology Enabling Transformation
This collaboration demonstrates how visionary energy providers like Eunice can leverage flexible industrial platforms to lead the transition toward a decentralized, decarbonized energy future. The integration of Revolution Pi is not just a technical solution – it’s a strategic pillar in Eunice’s roadmap for digital energy leadership.
