What affects the spot electricity price?
Spot electricity is based on Nordic power exchange prices, which vary with supply and demand. The market sets a separate price for each time period, and it can fluctuate significantly across the day and by season. This means opportunities to benefit from low prices – but also a risk of price increases.
Drivers include weather conditions, hydrological balance, fuel prices, wind and solar output, and overall consumption in the Nordic market area. Interconnectors to neighbouring countries and geopolitical situations also matter, as they can limit imports or push up energy prices across Europe. Typically, electricity is cheapest during windy periods, at night, on weekends and when demand is lower.
How is the billed price formed?
Your electricity sales price consists of the spot prices, the supplier’s margin, a fixed basic fee and VAT. A spot contract lets you influence your bill by shifting consumption to favourable times. For example, start EV charging, your water heater or the washing machine when electricity is cheapest. This saves money while generation-related emissions are at their lowest.
If you value control and accept price variation, a spot contract can be a smart choice. If you want to reduce the risk of rising prices, check our Spot+ contract, which lets you make fixed-term price locks as needed.
