> freshwater tanks are cheaper than electrical batteries, it seems appropriate to fully exploit the ability of tanks to displace energy production/consumption, and then, if needed, to use electrical batteries for the same purpose What about the cost of additional desalination equipment needed to take advantage of energy peaks? In a situation like this, is extra desalination equipment needed when renewable energy peaks? Or, do current desalination systems have periods where the equipment is idle?
