The developers of energy flexibility services turn flexibility which exists in the operation of assets into CO2 reductions or cost savings.
In effect, energy-consuming assets are turned on when the energy mix in the grid contains the most renewable energy (e.g. when the sun is shining) or when energy is the cheapest. Next to operation of processes, another prominent use case of energy flexibility are buffers and batteries.
Usually, this requires the software to plan a few hours ahead. No one likes assets to turn on and off suddenly.
