Stockholm  - Swedish state-owned energy group Vattenfall that also has activities in Germany and other Nordic neighbours was Tuesday reported to be considering a bid for British Energy.

Financial daily Dagens Industri cited unnamed sources that said Vattenfall's bid was worth an estimated 130 billion kronor (21.8 billion dollars), and that Vattenfall would need to combine with another energy group like Germany's E. On or a financial partner.

Vattenfall "does not comment speculation," spokeswoman Maria Parent told Deutsche Presse-Agentur dpa, adding that the Swedish energy group has earlier expressed interest in expanding its activities in northern Europe.

Britain was one of several priority growth markets listed in Vattenfall's full-year 2007 report.

Other groups that have shown interest in the British state's 35- per-cent stake in British Energy include RWE of Germany and EDF of France. (dpa)
