Vattenfall UK (formerly: Nuon Renewables) is a subsidiary of Vattenfall headquartered in London. It generates renewable energy, primarily through wind farms.
Vattenfall UK was established as Nuon Renewables in 2000. It was a United Kingdom-based subsidiary of N.V. Nuon Energy. It has built wind farms across the UK with a potential annual power generation total of eight hundred megawatts.
In 2009, N.V. Nuon Energy was acquired by Vattenfall. In January 2012, it was merged with Vattenfall's other assets in the United Kingdom and was renamed Vattenfall UK.
In March 2020, Vattenfall UK sold its electric vehicle network to Statkraft and its supply side business, Energy, to EDF Energy.
Vattenfall's core businesses in the United Kingdom are renewable power generation, heating, business-to-business sales and distribution. In 2025, Vattenfall UK began exploring the sale of its heating and electricity distribution businesses.
The company owns and operates numerous wind farms, some as small as their ten megawatt Parc Cynog wind farm, to others as large as Pen y Cymoedd Wind Energy, a 228-megawatt development. Their largest wind farm is Thanet, with a nameplate capacity of 300-megawatts. In 2023, Vattenfall UK announced that it planned to pause any further offshore wind farm development in Norfolk, and sold its Norfolk Wind Zone to RWE for ã1 billion.
