The name Nuon was a Dutch abbreviation for utility (NU) and for east (O) and north (N), which were that time the main markets for the company.

In 1999 also Energie Noord-West, Gamog and Energie- en Watervoorziening Rijnland were merged with Nuon and the name was changed N.V.

[11] On 7 September 2007, Nuon and Essent announced that the merger was canceled because no agreement could be reached on the exchange ratio.

In 2006, Nuon in the partnership with Royal Dutch Shell built NoordzeeWind (Egmond aan Zee) offshore wind farm.

Vattenfall is owned by the Swedish state, and the Reinfeldt cabinet was heavily criticized after the company was depreciated by SEK 15 billion post-purchase.

Vattenfall Nederland produces, sells and delivers electricity, gas, heat and additional services.
