Mr. John Melvin:

The technology that is being purchased is towards the end of the purchasing phase and, therefore, it is up to date. By the end of 2020, it is expected that there will be approximately 700 million smart meters, mostly in Europe and the USA. It is a major infrastructural project that will take a number of years to be rolled out. We underwent a number of phases in the evaluation of the project, which involved statistically relevant customer behaviour trials, a high-level design phase and a detail-level design phase. In 2017, we made the decision to roll them out because the cost-benefit analysis was such that it made sense. The most cost-effective way to roll it out was the phased approach that Ms MacEvilly described earlier, where we will do 250,000 from next year. Once the 250,000 have been completed, it will allow time for the communications infrastructure, that is, the backbone of all of this, to be put in at approximately the same time. We are, therefore, up to date.
