Electricity Load Lost in the Largest Windstorms—Is the Fragility-Based Model up to the Task?

“…Rauli (27 August 2016) was the most damaging among the recent windstorms [46], despite its moderate wind gust speeds compared to the previously mentioned windstorms. Rauli is an excellent example of an impactful summer windstorm where factors other than the wind gust speed influenced the final damages.…”

“…The Tapani (26 December 2011, named cyclone Dagmar in other Nordic countries) and Hannu (27 December 2011) winter windstorms occurred in quick succession, with only a partial grid restoration between them and, therefore, they are studied here as a single windstorm case. Taken together, Tapani and Hannu caused by far the largest disruption from windstorms in Finnish electricity system history [45,46]. The Tapani windstorm was a rare extratropical cyclone, moving eastwards exceptionally fast, and causing severe damage in Norway and Sweden on 25 December [47].…”

“…This dataset is presented in detail in the next section. The dataset does not contain information about repeating faults, which prohibits the derivation of the total number of customers affected that is commonly reported in secondary sources (Tapani-Hannu, 570 k [45,46] [46]). The average duration is computed as the ratio between the total consumer hours interrupted, and the peak number of consumers interrupted, which makes the average larger than it would be by computing the ratio with the total number of consumers interrupted.…”
