The year 2021 showed a sustained boom in wind power installations. The boom of wind deployment in Finland continues with 671MW new capacity in 2021, more than doubling the capacity additions from the previous year. The cumulative wind capacity at the end of 2021 increased by 26%, reaching 3,257 MW.
The wind share of electricity consumption stayed at 9.3%, similar to the previous year’s 9.6% (Finnish Energy (12.01.2022) “The energy year 2021”. Energiateollisuus). Wind-generated electricity reached 8.2TWh, a 5% increase compared to the previous year despite the 26% increase in capacity. The reason is the relatively normal year in terms of wind power index (0.98, close to the long-term average of 1.00), compared to the exceptional previous year ( index 1.17, meaning 17% over the long term average), which has compensated for the new wind capacity made available (Finnish Meteorological Institute (5.4.2022), Wind and wind power indices in Finland for 2016- 2021 based on ERA-5 100-meter wind speed.)
In 2021 Finland consumed 86.5 TWh of electricity, similar to pre-pandemic 2019 (86.1TWh). This represents a recovery from the 6% drop in electricity demand registered in 2020 due to the pandemic.
