Mr. Cathal Lee:

The Deputy asks a great question. The solution to this was posed by one of Ms McDonnell's colleagues in Clúid who asked, in view of the fact that the association was upgrading its entire housing stock over the next decade, what could be done for every resident as this was being done. The installation process on the immersion switch, for example, takes an hour. It is a very simple process that would be managed by Clúid or the relevant housing association. It is a straightforward process involving a registered installer. The key thing in terms of information is that the device communicates with Eirgrid and vice versa. That is the key functionality. As Mr. Mullins mentioned, when the curtailment signal kicked in at around 3 o'clock this morning, the tanks of residents in 18 counties across Ireland were heated up while they slept. It is a completely automated system. This morning they would have seen that their tank was full and they got a text message to confirm that. The key point is that the information flows between the retailer and the resident and EnergyCloud merely enables that process to take place. At the end of every month the participating retailers which are Prepay Power, Bord Gais Energy and SSE Airtricity at the moment, put the credit back on the resident's bill or on the prepayment meter, as applicable, based on the usage for those nights.
