Except for, which is variously classed as either a fossil fuel or a slow-renewable fuel, Finland imports all the fossil fuels used for electricity production. Coal and natural gas account for most of the production, with some oil generators acting mostly as reserve. The use of fossil fuels has fallen from highs over 30% in 2003–2004 to 20% or below in 2012–2014. By 2020 the share was closer to 10%. This is largely a consequ.

What is the electricity sector in Finland?
The electricity sector in Finland relies on nuclear power, renewable energy, cogeneration and electricity import from neighboring countries. Finland has the highest per-capita electricity consumption in the EU. Co-generation of heat and electricity for industry process heat and district heating is common.
How do electricity prices work in Finland?
Electricity retail prices in Finland are unbundled into several components. End-users pay for the energy itself and the delivery of that energy, plus government taxes. In practice, an electricity bill has three main parts: energy, network (transmission/distribution), and taxes, all of which are subject to VAT.
Does Finland have a spot-priced electricity market?
Finland's extensive use of spot-priced contracts (see next section) means many consumers experienced price volatility, but over the year Finnish retail prices (∼15–20 c/kWh for households) remained moderate by European standards.
What is Finland's Electricity sector like in 2021 & 2022?
The nation's electricity sector is further characterized by having a high per capita consumption rate and, in 2021 and 2022, high price volatility as a result of the ongoing global energy crisis. Discover all statistics and data on Electricity in Finland now on statista.com!
