IOANNIS S.
HATZIVASILEIADIS
Ioannis S. Hatzivasileiadis is a graduate Mechanical and Electrical Engineer (NTUA – National Technical University of Athens) who contributed to the development of renewable energy sources (RES) and sustainable electrical systems.
He worked at the Public Power Corporation of Greece (DEI/ΔΕΗ) from 1962 to 1990 as Director of Hydroelectric Stations and was involved in the construction of major power generation facilities. As head of renewable energy initiatives, he led the development of wind and solar power for electricity generation.
Through international collaborations, he helped develop the Kythnos Wind Park—the first of its kind in Europe—as well as the Kythnos Photovoltaic Station. Together, these projects formed the world’s largest hybrid energy system of their time, contributing significantly to the advancement of innovative technologies with strong international impact.
After 1990, he worked as a consulting engineer in the energy sector and, for many years, with the European Commission. His work focused on evaluating research proposals, managing and assessing research programmes, and acting as a technical advisor on major research projects related to future power grids with high penetration of renewable energy sources, within the framework of the European Commission’s research programmes.
He has served as a member of scientific committees in European and international conferences and has been a keynote speaker at numerous international conferences and workshops, with more than 80 publications. He has also been a member of national and European delegations for cooperation in research and technology, and served as national representative in the Mirror Group of the European Photovoltaic Technology Platform (2005–2012).
He is a founding member of the European Wind Energy Association (EWEA, 1982), a founding member of the Institute of Energy for South-East Europe (IENE), and served as its President (2013–2019). He was also a member of the Permanent Scientific Committee of the Panhellenic Association of Mechanical and Electrical Engineers (1999–2012).
As a pioneer in his field, he has received numerous honorary distinctions for his contribution to renewable energy research and development.
