Mr. Gary Connolly:

I can speak to that. On a smaller scale we found that battery systems can be used. Batteries really come into their own at a larger scale so we found that, especially on the dairy side of things, the cylinder is a thermal store in itself and we put kilowatt hours that would have been exported to the grid otherwise into the hot water store on that smaller scale on small dairy farms. As we got into larger farms actual lithium battery storage is an option for both peak shaving and moving into virtual power plants. Even then one moves into the utility grade solar and that is where the batteries really come into their own.
