In 2023, Greece's hydro power gross electricity production was 5.1 thousand gigawatt-hours. Although it marked a 2% year-on-year increase from 2022, the five-year compound annual growth rate (CAGR) from 2019 to 2023 was -2.41%, indicating a moderate declining trend.
Historic data from 2013 to 2023 shows considerable fluctuations, with significant year-on-year variations ranging from a 73.28% rise in 2021 to a -29.67% drop in 2019. The notable volatility reflects changing water inflows, policy shifts, and varying energy demands.
Future projections for 2024-2028 indicate a steady decline, with a forecasted -0.87% CAGR and an overall growth rate of -4.25%. Production is expected to slightly decrease each year, stabilizing around 4.83 thousand gigawatt-hours by 2028.
Future trends to watch for include the impact of climate change on water availability, further integration of renewable energy sources, and potential policy changes aimed at promoting sustainable energy production.
