About npower

npower is owned by the Innogy Group, based in Germany. It owns a range of different power stations including coal, oil and gas-fired stations as well as Innogy’s 160 wind turbines and 25 hydroelectric power schemes. As the third largest energy supplier in the UK, they supply gas and electricity to 6.5 million customers. Their initial plans to merge with SSE were called off but in April 2019, npower merged with Sainsbury’s Energy.

npower is big on renewable energy. Their sustainable management of energy and effort to reduce carbon usage means that they are one of the few energy companies to have received the Carbon Trust award. They even offer a Go Green Energy Fix Tariff which plants a tree when you start using gas or electricity with them.
