Timing electricity use to the spot price
With an exchange electricity contract (pörssisähkö), the price varies during the day, sometimes many times over. When you move flexible consumption to cheap periods, you save money and ease peak load on the grid. This guide shows how to follow prices and what is worth timing.
You will need
- An exchange electricity contract or information about your contract type
- A price app or your electricity company’s app
- Household appliances with a timer, or a smart plug
- Details of your hot water heater
Steps
Check your contract type
Check your electricity bill or your electricity company’s service to see whether you have an exchange-priced, fixed-term or open-ended fixed-price contract. Timing saves money directly only with an exchange contract, but with night-time or time-of-use transmission pricing the transmission fee may also be cheaper at night.
