Herrfors Nät-Verkko Oy Ab is a local distribution company in the Herrfors group, serving Jakobstad (Pietarsaari in Finnish) and the surrounding municipalities as well as the Ylivieska area, 34,000 metering points in all (2024). The network service price list applies from 1 January 2025, and household products carry no power fee, as the price list’s power products are meant for businesses. The general tariff (Yleistariffi) costs 3.93 c/kWh at any time of day, with a basic fee of €12.14 at 1 × 25 A, €13.57 at 3 × 25 A and €20.80 at 3 × 35 A per month. Flats in terraced houses and blocks have their own Kerrostalosähkö with a €9.16 basic fee and the same transfer fee. What sets Herrfors apart is general tariff B: also single-rate, but at only 2.97 c/kWh with a 3 × 25 A basic fee of €28.98. By our calculation it undercuts the general tariff from about 19,300 kilowatt-hours a year. On the time-of-day tariff (Aikatariffi) night runs from 22:00 to 07:00 under the price list, costing 1.92 c/kWh, and 3.08 c/kWh otherwise. Among the calculator’s 72 networks, Herrfors is number 27, counting from the cheapest, for a house using 5,000 kWh.

Herrfors’s household network prices
| Product | Transfer fee | Basic fee, flat | Basic 3 × 25 A | Basic 3 × 35 A | Power fee/month |
|---|---|---|---|---|---|
| Yleistariffi | 3.930 c/kWh | €9.16 | €13.57 | €20.80 | – |
| Yleistariffi B | 2.970 c/kWh | €28.98 | €28.98 | €46.43 | – |

In the flat column, the general tariff row shows the Kerrostalosähkö basic fee, which under the price list applies to flats in terraced houses and blocks. General tariff B and the time-of-day tariff are priced only for three-phase connections, so their flat column shows the 3 × 25 A basic fee.
Annual cost in the Jakobstad region
| User | Yleistariffi | Yleistariffi B | Aikatariffi |
|---|---|---|---|
| Flat, 2,000 kWh | €189 | €407 | €384 |
| House 3 × 25 A, 5,000 kWh | €359 | €496 | €464 |
| Electric heating 3 × 25 A, 18,000 kWh | €870 | €882 | €807 |
In an ordinary house the general tariff’s low basic fee decides it. In an electrically heated house the contest is between the two products with higher basic fees: tariff B lowers the price of every kilowatt-hour, the time-of-day tariff only of night-time ones. Charging an electric car overnight raises the night share and with it the time-of-day tariff’s advantage.
Switching product and electricity tax
According to Herrfors, you can switch network service product free of charge once every 12 months, so the choice can be corrected once a year’s real consumption is known. The price list’s transfer prices exclude electricity tax: in tax class I it is 2.9179 c/kWh including VAT and is billed separately. The calculator adds it to every quarter hour. Further south on the Ostrobothnian coast the operator is Vaasan Sähköverkko; compare every network in the transfer fee comparison.
