Who is Stable for?
Stable suits anyone who wants to keep electricity matters simple. A fixed energy price brings peace of mind — use electricity when you need it, without worrying about price swings.
It’s a great option if you value clarity and budget control. The price remains stable and any changes are moderate.
You can choose Stable if your place of use is within the Herrfors Nät-Verkko distribution area, your annual consumption is under 100,000 kWh, and the site has not had Stable or Stable+ contract in the last 12 months.

Fixed price
Your kWh unit price stays the same every day, with no sudden increases.
Predictability
Monthly costs are easier to plan.
Simplicity
No need to track the market or shift your usage.

Add renewable energy
Prefer clean power? Herrfors offers 100% renewable electricity (wind, solar, hydro or bioenergy) as an add-on for households and businesses.
