This is simple and not that costly to change. There are retrofit systems that allow a factor of 2 or 3 variability in electricity consumption, and even the ability to completely switch off for a few hours can smooth demand if it's planned rather than last resort. This allows a country like Australia to turn on or off 3-5% of its total electricity demand which is a decent chunk of the duck curve.
