Mr. John Mullins:

Regarding the question about the battery equivalent, when someone switches on his or her immersion, it is generally a 3 kW load when he or she switches on his or her own. If 100,000 homes opt in to this scheme, and we already have 75,000 registered to join, you add the equivalent instantaneously when the curtailment signal goes out of 300 MW of extra demand on the system, which means you keep 300 MW of zero equivalent renewable energy less wastage on the grid. This is why we can do the things we are doing whereby that wastage is converted into a fruitful exercise, which is to warm water to boiling point or equivalent and then provide stability on the grid by instantly bringing 300 MW and not having to take off wind farms. That is the concept. The price of a 300 MW battery based on my own guesstimates would be about €150 million to build and you could not do that in one location. You would have to do it over three or four separate locations.
