    ILIS Project

    First European experience in the operation of a commercial photovoltaic plant with batteries

    The ILIS project aims to design a management system for multi-megawatt photovoltaic plants using ion-lithium batteries as an ideal solution for improving the quality of the energy generated, favoring its integration into the grid and providing a higher penetration of solar PV in the electric power system. It is the first experience in Europe of incorporating batteries into a photovoltaic plant in commercial operation.

    ILIS aims to contribute smart control systems based on parameters such as weather forecasts, incorporating the use of ion-lithium batteries to guarantee the injection of power to the grid in the absence of the solar resource. This facilitates a greater integration of this energy into the system and provides a reliable and safe solution for large-scale photovoltaic plants to respond to the technical requirements of the most advanced grids.

    CONTENT AND ACTIVITIES

    • The project was carried out in the photovoltaic solar plant of ACCIONA in Tudela (Navarra). Through ILIS, the company wished to valorize all the experience gained in the construction and operation of this kind of installation in order to improve its performance.
    • A key element in the project was the development of a new centralized management and control system for the plant – carried out by ACCIONA – taking into account parameters such as weather forecasts, grid requirements and the previous performance of the plant and the set of batteries. It also provided real-time information to the system operator, thus optimizing its integration into the electric power system.
    • Another new feature of the ILIS project is the use of latest-generation batteries. The system provides the energy necessary to manage the installation, avoiding quick power fluctuations due to environmental factors such as cloud cover, and facilitates the primary and secondary regulation of the power grid as a help to ensuring the stability of the system.
    • The company Saft has developed this system with latest-generation batteries (ion-lithium), which have a long life, high efficiency, zero maintenance and facilitate the measurement of the load and other operational parameters. The whole 1.1 MW battery system is containerized, which means it can easily be scaled up for future applications.
