Geothermal power production in the UK is forecasted to exhibit a gradual, consistent increase from 2024 to 2028, starting at 9.57 Gigawatt hours (GWh) in 2024 and reaching 9.65 GWh in 2028. In 2023, actual production was at 9.55 GWh. Year-on-year variation remains modest, with increments of approximately 0.1% annually. The compound annual growth rate (CAGR) over the five-year period from 2023 to 2028 is roughly 0.21%, indicating a stable but slow growth trajectory.

Despite the predictability in these values, certain future trends warrant attention:

Technological advancements in geothermal energy extraction and efficiency improvement.
Government policies and investment to promote renewable energy sources.
Potential competitive pressures from other renewable energy sources such as wind and solar.
Changes in public and corporate attitudes towards sustainable energy initiatives.
