Hydroelectricity generation in Spain experienced significant fluctuations over the past decade. Peaks occurred in 2014 with a generation of 39.17 TWh, while the lowest production was registered in 2017 and 2022, at around 18 TWh. Although specific years witnessed substantial increases or decreases in year-on-year variation, the overall trend depicted volatility. In 2023, hydroelectric generation stood at 29.5 TWh.
Recent years (2022-2023) saw a pronounced rebound with a 61.74% year-on-year increase in 2023, highlighting a recovery from the prior year's low. However, looking at the last five years, the average annual growth rate (CAGR) showed a decline of -2.99%, demonstrating overall instability.
Forecasts from 2024 to 2028 remain steady at 29.5 TWh annually, reflecting a projected stable generation without anticipated growth or decline. The forecasted five-year CAGR is 0%, suggesting no expected change in the hydroelectric output during this period.
Future trends to watch for include advancements in hydroelectric technology, potential government policy shifts towards renewable energy incentives, and the impact of climate change on water resources, which could all significantly influence hydroelectric generation in Spain.
