The data was published in the 39th edition of Aragon’s Energy Situation Bulletin. The report helps the regional government track changes in energy production and consumption and make decisions on the region’s energy policy.
Aragon generates twice as much energy as it consumes and becomes an electricity supplier
ENERGY CONSUMPTION RISES IN ARAGON
Primary energy consumption, which includes all the energy needed to sustain economic activity and generate electricity, rose by 5.3% in 2025 to 5,315,029 tonnes of oil equivalent (toe). Final consumption, meaning the energy used directly by households, businesses and other sectors, increased even further, by 7.7%, to 3,910,709 toe.
One of the main reasons was the increase in electricity consumption. More gas was also used, both by industry and combined-cycle power plants. These facilities had to operate for longer hours to help keep the electricity system stable, causing renewables to lose some of their share of total energy use.

INDUSTRY CONSUMES MORE AND TRANSPORT LESS
Industry once again became the sector that consumes the most energy in Aragon, with demand increasing over the past year. The regional government views this growth as a sign of increased industrial activity. By contrast, consumption of petroleum products in transport declined.
Household and services-sector energy consumption also grew significantly. In the latter sector, the management and development of data centers in Aragon is already beginning to have an impact. In homes, both electricity and gas use increased.

ARAGON BECOMES MORE DEPENDENT ON ENERGY FROM ABROAD
This increased use of gas has reduced Aragon’s ability to meet its energy needs with its own resources. The self-sufficiency rate fell from 47.7% in 2024 to 43.5% in 2025. The reason is that Aragon produces a great deal of renewable energy but needs to import the gas used in power plants and other activities.

83% OF INSTALLED ELECTRICITY CAPACITY IS NOW RENEWABLE
In electricity, renewable growth remains very strong. Renewable sources now account for 83.3% of all installed capacity in Aragon, up from 80% the previous year. During 2025, 22,365 gigawatt-hours (GWh) were generated, 2.8% more than in 2024.
Despite this, the share of renewable electricity in total generation fell from 90.1% to 83.4%. This was mainly due to greater use of gas-fired combined-cycle power plants. At the same time, electricity consumption in Aragon grew by more than 4% to 10,836 GWh.

ARAGON CONTINUES TO EXPORT MORE THAN HALF OF ITS ELECTRICITY
Aragon continues to produce far more electricity than it consumes. In 2025, it exported 11,529 GWh, equivalent to 51.5% of all the electricity generated in the region. The figure was slightly lower than the previous year, when 11,850 GWh were exported, due both to higher domestic consumption and grid limitations that prevented all the output from being transmitted.
This capacity problem is one of the main challenges facing Aragon’s energy system. Although more renewable plants are installed each year, not all of this new capacity can be used. Wind power reached 6,063 MW of installed capacity and generated 11,029 GWh, while solar photovoltaic power reached 3,270 MW and set a generation record with 4,190 GWh. In just four years, Aragon has practically increased its solar photovoltaic capacity tenfold.
