There's a northern German copper plant which can dynamically adjust its energy usage to the availability of renewable energy. If the availability is low, they reduce their production and thereby greatly help the grid. I could imagine plenty of large consumers to dynamically adjust their processes to the price of energy, obviously costs money to setup and maintain, but will be beneficial regardless with very fluctuating energy prices due to the intermittency of renewable energy.
