Interesting strategic move from Drax following its well-publicised retooling towards biomass-fired generation. The acquisition of Opus Energy would propel Drax's retail arm, Haven, into the top 5 business energy suppliers, and would seem to represent a sound strategy. 

It also continues the consolidation of the supply market, and following the high profile failure of GB Energy, more deals for access to suppliers' customer bases can be expected to follow.
