Grid Storages in Norway
Norway has 6 grid storages mapped on the OverWatts open energy atlas — the 18th-largest fleet of the 58 countries that hold any, and 0.6% of the world's mapped total. Of these, 5 operating and 1 under construction or proposed. The largest is Aurland 3 hydroelectric plant (290 MW).
The largest owner-operators are Norsk Hydro ASA (2), Statkraft AS (2) and Eviny Fornybar AS (1) — Norsk Hydro ASA alone is named on 33% of them. Half of Norway's grid storages in service predate 1979 (median commissioning year of the 5 with a known date) and the oldest still listed is Herva hydroelectric plant, dating from 1962. 1 is in the pipeline, led by Illvatn hydroelectric plant (48 MW), under construction.
