This is welcomed and refreshing news that Engie and Octopus Energy and entering the electricity supply market with a model based around aligning retail and wholesale prices.

The traditional energy companies don't seem to be keeping up with what consumers want. Coupled with the fact Engie offer 100% renewable energy at no extra cost, what's not to like!
