The Iceland Power outages 2010 was a massive, widespread power outage that occurred nationwide in Iceland, on Wednesday, September 1, 2010, at approximately 21:00 GMT. At the time, it was one of the most widespread electrical outages in Icelandic history. An estimated 200,000 people in Iceland were affected. The three largest aluminium smelters in Iceland were hit by the outage, leaving Century Aluminum Grundartangi and Rio Tinto Alcan Straumsvik totally off-grid. The third aluminium smelter, Alcoa Fjardaal, was forced to reduce its operations to a bare minimum. Hot water became immediately scarce in some of the neighborhoods in Reykjavík, the capital.
