Drax has completed its acquisition of business energy supplier Opus Energy.

Drax’s board said Opus will enhance Drax’s retail offering “by combining the leading ‘challenger’ small and medium enterprise business with Haven Power’s strength in the industrial and commercial market”.

Haven is Drax’s existing business customer brand. In the year to December 2015 it made a gross profit of £19 million on a £1,290 million revenue, with 30,000 meter points. In comparison, in the year to March 2016, Opus Energy made £107 million profit on revenues of £573 million.
