Our history

Our company, like our industry, has evolved constantly since the electricity industry was privatised in the early 1990s, when we became National Power, one of the UK’s leading power generators.

Over the next ten years we transformed the business by disposing of excess generating capacity.  Through the acquisition of Midlands Electricity, Calortex, and Independent Energy, we also established a substantial presence in the supply market.  In April 2000 our various supply businesses were relaunched under a single brand, npower.  By becoming an integrated company with both generation assets and a retail business, we were well placed to operate competitively in the volatile UK energy markets.

In 2000 National Power demerged to created Innogy, a leading integrated UK energy company, and International Power.  As Innogy we acquired the supply businesses of Northern Electric and Yorkshire Electricity, which increased our customer base to nearly 7 million.

In 2002 we were acquired by RWE, one of Europe’s leading utilities and became RWE npower, the UK energy business of the RWE Group.

On 1 February 2008 the renewable generation assets of the RWE Group were consolidated in a new operating company, RWE Innogy.  In the UK, the renewable business of the Group is RWE npower renewables.

In January 2013 RWE Generation SE began operation to provide a focused pan-european generation business. RWE Generation steers RWE's portfolio of power generation across Europe, including RWE npower’s UK plant portfolio - a total power generation of around 40,000 MW at more than 50 sites.
