Grid Storages in Italy
Italy has 23 grid storages mapped on the OverWatts open energy atlas — the 8th-largest fleet of the 58 countries that hold any, and 2% of the world's mapped total. Of these, 21 operating and 2 under construction or proposed. The largest is Entracque Chro hydroelectric plant (1.1 GW).
The largest owner-operators are Enel SpA (16), Dolomiti Energia (2) and Edison SpA (2) — Enel SpA alone is named on 70% of them. Half of Italy's grid storages in service predate 1971 (median commissioning year of the 15 with a known date) and the oldest still listed is Venina hydroelectric plant, dating from 1923. 2 are in the pipeline, led by Pescopagano hydroelectric plant (270 MW), under construction. They account for 4% of every energy asset OverWatts maps in Italy.
