Two products, one basic fee whatever the fuse
| Product | Transfer fee | Basic fee, flat | Basic 3 × 25 A | Basic 3 × 35 A | Power fee/month |
|---|---|---|---|---|---|
| Yleissiirto | 4.720 c/kWh | €6.53 | €6.53 | €6.53 | – |
| Aikasiirto | day 2.960 c/kWh · night 1.560 c/kWh | €20.46 | €20.46 | €20.46 | 1.97 €/kW |
Helen’s general transfer is simple: a fixed basic fee and one transfer price around the clock. For a spot customer in Helsinki the cheapest quarter is therefore always the one with the cheapest exchange price. On time-of-day transfer night transfer is 1.40 c/kWh cheaper than day, which shifts the cheapest window towards the night.
The power fee changes the sums
| User | Yleissiirto | Aikasiirto |
|---|---|---|
| Flat, 2,000 kWh | €173 | €412 |
| House 3 × 25 A, 5,000 kWh | €314 | €485 |
| Electric heating 3 × 25 A, 18,000 kWh | €928 | €802 |
The table includes the power fee at a 5 kW peak in the time-of-day cost. With a 10 kW peak the power fee rises to about €236 a year. Running the sauna, the car charger and heating at the same time drives the peak up fast. Staggering loads across hours and moving the largest use to the night, when only 80% of power counts, cuts the fee. More in the power fee guide.
The spot price for a Helsinki household
Transfer in Helsinki is cheaper than in many rural networks, so the exchange price is a bigger share of the all-in price. When spot is near zero, a kilowatt-hour still costs transfer plus tax, 7.64 c/kWh before the margin. In an expensive hour the gap is large. Compare with the neighbouring areas in Espoo and Caruna Oy’s area.
