The production of nuclear heat in Finland experienced fluctuations from 2013 to 2023, hovering around 238,000 Terajoules in 2013 and standing at approximately 235,690 Terajoules in 2023. The year-on-year variations oscillated, with notable declines in 2017 (-3.57%) and 2020 (-2.26%), and increases in 2019 (4.26%) and 2021 (1.11%). The compound annual growth rate (CAGR) over the five years leading up to 2023 was modest at 0.67%, indicating a stable yet slightly increasing trend.

Future trends to watch for:

The forecasted CAGR for the next five years is estimated at 0.14%, suggesting a continued, albeit slow, growth in nuclear heat production.
Increases in production are expected to be incremental, with annual outputs projected to rise steadily to about 237,740 Terajoules by 2028.
Technological advancements and policy changes could impact future production levels, either accelerating growth or causing new fluctuations.
