    Chisachi Kato

    Dr. Chisachi Kato is a professor of mechanical engineering at the University of Tokyo. In 1984, he graduated the Graduate School of Engineering at the University of Tokyo and obtained a master’s degree in mechanical engineering. He obtained another master’s degree from Stanford University in August 1989. He was conferred his doctoral degree in engineering from the University of Tokyo in 1995. Upon graduation from the mechanical engineering department at the University of Tokyo in 1984, Dr. Kato joined the Mechanical Engineering Research Laboratory of Hitachi, Ltd. and had been working as a research engineer for about 15 years. In January 1999, Dr. Kato moved to the Institute of Industrial Science (IIS), the University of Tokyo and was appointed as a professor in January 2003. Since then, he has also been a director of Center for Research on Innovative Simulation Software (CISS).

    XFLEX Hydro: a technology road map for Hydroelectric power plants to enable massive photovoltaic and wind penetration of the electric power system


    Prof. François Avellan. École polytechnique fédérale de Lausanne (EPFL), Lausanne, Switzerland.

    François Avellan

    Prof. Avellan, director of the EPFL Laboratory for Hydraulic Machines, graduated in Hydraulic Engineering from Ecole nationale supérieure d'hydraulique, Institut national polytechnique de Grenoble, France, in 1977 and, in 1980, got his doctoral degree in engineering from University of Aix-Marseille II, France. Research associate at EPFL in 1980, he is director of the EPFL Laboratory for Hydraulic Machines since 1994 and, in 2003, was appointed Ordinary Professor in Hydraulic Machinery. Supervising 37 EPFL doctoral theses, he was distinguished by SHF, Société Hydrotechnique de France, awarding him the "Grand Prix 2010 de l'Hydrotechnique". His main research domains of interests are hydrodynamics of turbine, pump and pump-turbines including cavitation, hydro-acoustics, design, performance and operation assessments of hydraulic machines. Prof. Avellan was Chairman of the IAHR Section on Hydraulic Machinery and Systems from 2002 to 2012. He has conducted successfully several Swiss and international collaborative research projects, involving key hydropower operators and suppliers, such as:

    • Scientific Advisor to the Coordinator of the Hydropower Extending Power System Flexibility (XFLEX HYDRO) project which has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 857832.
    • Coordination for the FP7 European project no 608532 "HYPERBOLE: HYdropower plants PERformance and flexiBle Operation towards Lean integration of new renewable Energies" (2013-2017);
    • Deputy Head of the Swiss Competence Center for Energy Research – Supply of Electricity (SCCER-SoE) to carry out innovative and sustainable research in the areas of geo-energy and hydropower for phase I (2013-2016) and Phase II (2017 2020).
    • EUREKA European research projects: No 4150 and No 3246, "HYDRODYNA, Harnessing the dynamic behavior of pump-turbines", (2003-2011), No 1605, "FLINDT, Flow Investigation in Draft Tubes", (1997-2002), No 2418, "SCAPIN, Stability of Operation of Francis turbines, prediction and modeling";
    • Swiss KTI/CTI research projects with GE Renewable Energy (anc. ALSTOM Hydro, Birr), ANDRITZ Hydro (Kriens), FMV (Sion), Groupe E (Granges-Paccot), Power Vision engineering (Ecublens) and SULZER Pumps (Winterthur).
    • ETH Domain, HYDRONET Project for the Competence Center Energy and Mobility, PSI Villingen.

    Furthermore, he is involved in scientific expertise and independent contractual experimental validations of turbines and pump turbines performances for the main hydropower plants in the world. In recognition for his work as Convener of the TC4 working group of experts in editing the IEC 60193 standard he received the "IEC 1906 Award" from the International Electrotechnical Commission.


    With increasing levels of variable renewables in the energy system, new opportunities emerge for hydropower as a provider of flexibility services in modern power markets. To address this question, a consortium of 19 European partners is committed to the Hydropower Extending Power System Flexibility (XFLEX HYDRO) project.

    The ultimate objective of the XFLEX HYDRO project is to increase hydropower potential in terms of plant efficiency, availability and provision of flexibility services to the Electric Power System (EPS).

    The high Renewable Energy Sources (RES) scenario of the decarbonisation process relies on a drastic change of the European Union EPS with a massive integration of non-dispatchable RES and disconnection of the so-called conventional units, as greenhouse gases emitters. These changes influence drastically the provision of the power grid balancing, and challenge the EPS operations and safety. It is of upmost importance to provide reliable solutions to support the EPS with more flexibility services. Hydroelectric Power Plant (HPP) already significantly supports EPS flexibility in terms of regulation capability, fast frequency control, fast start/stop, fast generating to pumping modes transition, high ramping rate, inertia emulation, fault ride through capacity, etc.

    The XFLEX HYDRO project aims to demonstrate an innovative methodology for system integration of hydroelectric technology solutions, variable speed being a key component and a reference, to provide further enhanced flexibility services assessed by a crosscutting analysis of their impact on both the technology and the market aspects.

    Innovative solutions also target an optimize maintenance plan to decrease the outage time and increase the availability of the plant. Seven demonstrations are scheduled in the cases of run-of-river, storage and pumped storage HPPs and they cover cases of refurbished, uprated and especially existing HPP to be applied and scaled to any unit size. XFLEX HYDRO draws the roadmap for the exploitation of its solutions to all the European HPP fleet. A strategic dissemination plan is set to promote the deployment of the demonstrated solutions to stakeholders, to the scientific community and the public and to further support the communication in workshops, conferences, scientific journals, newspapers and various social media.
