ALDIS (Austrian Lightning Detection and Information System) is a joint project of OVE Austrian Electrotechnical Association and Austrian Power Grid AG . The goal of this project is real-time monitoring of lightning activity in the area of Central Europe and providing this information to meteorological services, insurance companies and power utilities. In addition the results of lightning research activities by the ALDIS team are well acknowledged by the international research community and documented in numerous journal papers and conference contributions.

BLIDS (BLitz Informations DienSt) was operated by SIEMENS Germany for decades and was taken over by ALDIS in October 2023.

As there was already close cooperation between ALDIS and BLIDS before the takeover, the merger will not change the historical and current lightning data available.
