Energy Statistics for Scotland – Q3 2025

Electricity Generation and Supply

In 2024, 51.8 TWh of electricity was generated in Scotland. Of this, 73.1% (37.9 TWh) was generated from renewable sources and 91.5% (47.4 TWh) was generated from low carbon sources (renewables + nuclear + pumped storage). In comparison, 49.9 TWh of electricity was generated in Scotland in 2004, with 11.7% generated from renewable sources and 49.4% generated from low carbon sources (renewables + nuclear; Figure 5 and 6).

Note - ‘All low carbon’ includes electricity generated from renewable and nuclear technologies for 2004 and 2024. Pumped storage is also included in the 2024 figure as the majority of electricity generated in Scotland in 2024 came from renewable sources.

Scotland has seen a steady rise in the amount of electricity generated from low-carbon sources over the last two decades from 24.7 TWh in 2004 to 47.4 TWh in 2024. This has been driven by the increase in renewable electricity generation, up from 5.8 TWh in 2004 to 37.9 TWh in 2024. Conversely, there has been a steady decline in the amount of electricity generated from fossil fuels, from 25.3 TWh in 2004 to 3.6 TWh in 2024. Electricity generated from other low carbon sources has roughly halved since 2004. This is mainly due to the closure of the Hunterston B nuclear power station in 2022 (Figure 6).
