I thank my hon. Friend for his interest in both these important topics. The National Infrastructure Commission has estimated the benefits of a smart energy system to be between £3 billion and £8 billion a year by 2030.
I am grateful to the Minister for his response and am pleased that he agrees with the advantages of a smart energy system. Ahead of the autumn statement, will the Minister look at the role that the Treasury might play in digitising our energy system by accelerating the deployment of storage technologies, demand-side response and the upgrade of our distribution networks so that we can achieve the productivity gains he expects?
