From Accounting Sufficiency to Technical Sufficiency of the Electrical System

Published January 28, 2026, 10:32

Dr. Andreas Prokopiou, a former senior researcher in smart grids, analyzes the weaknesses of studies that approach the energy transition as a simple balance between energy production and consumption. He points out that such approaches overlook the dynamic nature of electrical systems and critical parameters such as stability, reliability, and the ability to cope with extreme events. Dr. Prokopiou specifically criticizes a recent study on Cyprus's energy independence, which proposes covering electricity demand through photovoltaics and storage, arguing that this leads to over-sizing of the system and forced production cuts. Furthermore, he emphasizes that energy storage is presented as a panacea without considering the real limitations and technical challenges involved. The simplified presentation of such scenarios creates a false impression of the complexity of operating an electrical system. Overall, Dr. Prokopiou argues that the energy transition requires in-depth analysis of power systems and their dynamic behavior, and not just simple energy balances, in order to ensure the safe, reliable, and stable operation of the electrical system.
