In a remarkable turnaround, utilities in Portugal have significantly reduced the proportion of electricity production from fossil fuels to just 10% in 2024, surpassing Spain and emerging as the second-cleanest large power sector in western Europe, behind France.
Data from energy think tank Ember shows that total clean electricity generation in Portugal has jumped 32% from the same period in 2023, reaching a record 21.76 terawatt hours (TWh) in the first seven months of 2024. This surge in clean power production has been driven by record output from solar and wind farms, as well as the highest hydro generation total since 2016, allowing generators to slash natural gas-fired output by 60% compared to the same period in 2023.
Portugal's power firms have also increased total electricity generation by 7%, the highest since 2021, showcasing the effectiveness of a multi-pronged approach to boosting clean generation.
Analysis:
The deployment of large new hydro dams and solar parks in Portugal has played a pivotal role in reducing the use of fossil fuels in the country's power sector. With the commissioning of projects like the Tamega dam and Cerca solar farm, total fossil fuel-generated electricity has been cut to just 10% in 2024. This significant decrease in fossil fuel use has led to a 45% reduction in total power sector emissions, setting a new record for the country.
Furthermore, the increase in hydro generation, driven by projects like the Tamega facility, has significantly boosted Portugal's clean energy production. The share of hydropower in the electricity generation mix has increased to 35.3% in 2024, compared to 20.7% in 2023. Solar and wind assets have also seen their shares climb, indicating a positive trend towards cleaner energy sources.
Portugal's commitment to increasing the weight of renewables in power production, with the goal of becoming carbon neutral by 2045, is a step in the right direction. Innovative projects like the Alqueva floating solar park and the integration of wind farms into existing energy projects show promise for further growth in clean energy production.
Overall, Portugal's current momentum and planned expansions in solar and wind capacity position the country as a leader in energy transition. By prioritizing renewables and implementing innovative solutions, Portugal is well on its way to becoming a global clean energy champion.
