Four categories of flexible behaviours that can be beneficial to the Power System include:
- Shape – Increasing or decreasing Demand routinely according to a recurring long-term pattern;
- Shift – Increasing or decreasing Demand as requested in response to an external signal;
- Shimmy – Increasing or decreasing Demand over very short timescales in response to an external signal; and,
- Shed – Switching off equipment entirely.
