In 2023, the gross available energy from geothermal power in Belgium was recorded at 40.44 Gigawatthours. The forecasted data for 2024 to 2028 show very minimal growth. Specifically, from 2024 to 2026, the value remains steady at 40.44 Gigawatthours. A slight increment to 40.45 Gigawatthours is expected in 2027 and continues into 2028. This translates to a year-on-year variation of 0% from 2024 to 2026 and a negligible increase of approximately 0.02% from 2026 to 2027 and 2027 to 2028. The CAGR over the last five years (2023-2028) is close to 0%, indicating a stagnation in growth.

Trends to watch for in the future include:

Potential technological advancements that could increase the efficiency and output of geothermal power plants.
Government policies and incentives aimed at renewable energy expansion, which could influence growth in this sector.
Market demand for sustainable energy solutions which might drive investment in geothermal energy infrastructure.
