The International Symposium on Lightning Protection (SIPDA) is a scientific event organized every two years whose main goal is to contribute to the discussion and dissemination of innovations in lightning technology. It covers all lightning-related aspects, including lightning physics and characterization, measurements, modeling techniques, detection and location systems, grounding, protection methods, and accidents and damages associated with the phenomenon.

The symposium is organized by the Institute of Energy and Environment of the University of São Paulo (IEE/USP), with the technical co-sponsorship of the Institute of Electrical and Electronics Engineers (IEEE).

This year, the XVIII SIPDA will be held in Thessaloniki, Greece, from September 21 to 26, 2025.

All papers will undergo the same review process, and prospective authors are invited to submit their contributions by May 15, 2025, through the website https://sipda2025.gr/home.

The SIPDA 2025 has the wide support of the international community and organizations from academia, industry, and business, and we are confident that it will be one of the greatest events ever held in the field of lightning research.

We are looking forward to meeting you in Thessaloniki in 2025!
