Consumer appetite to participate in last winter’s Demand Flexibility Service (DFS) significantly drove smart meter uptake among Octopus Energy customers, the company’s chief executive has told Utility Week. Octopus saw almost 700,000 customers take part in its Saving Sessions to help reduce peak demand on the power grid over winter as part of the Electricity System Operator’s DFS. During an extended interview at Octopus’ London HQ recently, the supplier’s founder and chief executive Greg Jackson spoke about the impact the company’s participation in the DFS had in regards to its smart meter rollout.
