Npower Limited is a UK energy retail company supplying electricity and natural gas, primarily to business and industrial customers. It operates as part of E.ON UK, with services marketed under the npower Business Solutions brand. The company provides energy supply and related account management for large users across sectors, including manufacturing and process industries.
Npower originated from the UK operations of Innogy and RWE (formerly RWE npower), where it was a major participant in the liberalized UK power and gas market. Following market consolidation and E.ON’s acquisition of innogy assets, Npower’s retail activities were integrated into E.ON UK. The business today focuses on energy supply and customer service rather than power generation, reflecting the wider shift in the UK utility sector away from owning large fossil-fuel generation assets.
