Flexible electricity (load shifting)
Shift consumption automatically from expensive periods to cheaper ones – e.g. heating, a water heater, or EV charging.
Start here
- Choose one flexible load first, such as a water heater or EV charging.
- Create one simple price rule and watch how it behaves for a few days.
- Use Cost analysis to confirm that usage really moved to cheaper periods.
How do the contract and control work together?
In flexible contracts, the final price typically includes a fixed energy part, a monthly fee, and a consumption effect. The consumption effect can reduce or increase your realized price depending on when you use electricity.
- If your usage is shifted to cheaper hours, the consumption effect can lower your billed price.
- If your usage is concentrated in expensive hours, the consumption effect can increase your billed price.
- Optimaatti shifts controllable loads automatically to cheaper periods, making it easier to realize contract benefits in practice.
- The consumption effect varies month to month, so evaluate results over a longer period (for example 1–3 months).

1
Verify your contract and basics
Flexible electricity uses hourly prices. Make sure your electricity plan is spot-priced or otherwise flexible.
- Check your contract type and price area.
- Make sure your device is connected to Optimaatti and appears in your device list.
2
Create a rule or enable predictive control
You can use price rules or predictive control (MPC) to shift consumption.
- Price rules provide simple thresholds and schedules.
- MPC creates an automatic plan while staying within comfort limits.

Monitor and fine-tune
Follow the control status and ensure your device behaves as expected.
- See when control is on and when it is off.
- Adjust limits or comfort settings if the control is too aggressive or too conservative.
