The gross available energy from hydro power in Belgium shows significant annual fluctuations from 2013 to 2023. In 2023, the available energy stood at 1.05 thousand terajoules. Year-on-year growth for 2023 was marginal at 0.9%. From 2019 to 2023, the compound annual growth rate (CAGR) was nearly neutral at -0.005%, indicating stable but non-increasing output. Over the past decade, growth rates witnessed significant volatility, peaking in 2021 with a year-on-year increase of 56.65% and the lowest point being 2017 with a -27% decline.
Looking ahead to 2028, the forecast suggests a gradual decline, with a 5-year CAGR of -1.15%. This reflects a projected decrease in hydro power energy by about 5.64% over the next five years, indicating a consistent downward trend.
Future trends to watch for include advancements in hydro power technology, potential changes in climate affecting water flow, and energy policy adjustments at the national level. Strategic investments in renewables and infrastructure are crucial for countering the predicted downward trajectory.
