Finland Electricity Tariff API

How a household electricity price is built in Finland

Finland has been fully open and unbundled since the late 1990s: a household buys energy from any supplier nationally, while a separate, area-exclusive distribution company bills a distinct transfer charge on its own invoice. There is a single national price area, so there is no regional wholesale variation — only variation by network operator for delivery. Finland stands out for how mainstream spot-price exposure has become, with roughly a third of household contracts priced directly off the exchange.

What a household bill is made of

1. 1

   Energy

   Traded day-ahead in one national bidding zone, now in quarter-hourly market time units. Fixed-term products (typically 6, 12 or 24 months) and open-ended products changeable on a month’s notice cover the static side; exchange-priced products pass the market price through per interval with a small margin and a monthly fee. A growing hybrid class mixes a fixed component with a term that depends on the customer’s own hourly profile against the market curve — those cannot be priced without a consumption profile.

2. 2

   Network charges (siirto)

   Set per distribution company under revenue-cap regulation and not contestable — the operator follows the address. The mass-market product is a flat general transfer tariff: a per-kWh energy charge plus a monthly basic fee banded by main-fuse size. Day/night, seasonal and power-based variants exist, and a customer may change metering product once a year free of charge. A harmonisation regulation is standardising these components nationally by 2029, including an optional power charge above a threshold, while preserving households’ right to a product without one.

3. 3

   Taxes and levies

   One statutory electricity tax, billed on the network invoice, published as an energy-content component plus a small strategic-stockpile fee. Households, services, farms and the public sector all pay the higher of the two tax classes; the reduced class is for industry, data centres and professional greenhouse growing. There is no renewable levy, no concession fee and no capacity charge on a Finnish household bill — production support comes from the state budget.

4. 4

   VAT

   25.5%, applied to every component of both invoices — the energy charge and its monthly fee, the transfer charge and its monthly fee, and the electricity tax itself.

Regulation shaping the price

• Energiavirasto caps distribution revenue, sets the harmonisation rules for tariff structure, and runs a free official price-comparison service that every supplier must file its generally offered products into.
• Suppliers may not issue price-change notices for products tied to a public reference price, which is why exchange-linked products are contractually simpler than variable fixed-price ones.
• There is no feed-in tariff. Microgeneration is first netted against consumption nationwide through the metering data hub, now per 15-minute period, and only the remaining surplus is sold — normally at the area spot price minus the buyer’s margin.
• Microgeneration up to 100 kVA is exempt from electricity-tax obligations, so no levy attaches to the feed-in side.
