What the numbers say
In 2025, Slovak Republic's electricity production from nuclear sources (% of total) rose 4.98 percentage points on 2024 (from 60.64% to 65.62%).
Across the 30 yearly changes before that (1995 to 2024), the average change was +0.39 percentage points and a typical year strayed about 2.61 percentage points from that (the standard deviation). This year's change was 1.8 standard deviations above that average, so it was larger than a typical year, though not out of the range seen before.
On record, the biggest yearly rise was 6.91 percentage points in 2022 and the biggest yearly fall was 6.27 percentage points in 1995. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.
From 2016 to 2025 the straight-line trend is upward, about 1.15 percentage points a year. A straight line explains 64% of the movement over 10 observed years.

What this measures
The share of electricity production from nuclear sources of total electricity production. Sources of electricity refer to the inputs used to generate electricity. Nuclear power refers to electricity produced by nuclear power plants.
Limitations: IEA occasionally revises its time series to reflect political changes. For example, the IEA has constructed historical energy statistics for countries of the former Soviet Union. In addition, energy statistics for other countries have undergone continuous changes in coverage or methodology in recent years as more detailed energy accounts have become available. Breaks in series are therefore unavoidable.
Regional and income-group figures are computed by the World Bank as a weighted average using total electricity production as weights.
