Vattenfall is a Swedish power company, wholly owned by the Swedish government. Beyond Sweden, the company generates power in Denmark, Finland, Germany, the Netherlands, Poland, and the United Kingdom. In January 2016, Vattenfall announced that all its Swedish nuclear power plants, including the newer reactors, were operating at a loss due to low electricity prices and Sweden's nuclear output tax. It warned that it may be forced to shut all the nuclear plants down, and argued that the nuclear output tax should be scrapped.
The company's name is Swedish for " waterfall", and is an abbreviation of its original name, Royal Waterfall Board (Kungliga Vattenfallstyrelsen).
