In the Aragonese community there has been a significant increase in the production of electricity from renewable sources. In wind power it has increased by 41% and in solar photovoltaic by 364%.
According to the 2020 Energy Situation Bulletin, primary energy consumption in Aragon, that obtained from natural energy sources plus the loss in transformation and transportation, decreased by 5.6%.
Faced with this decline, the upward trend in the use of renewable energies continued, reaching 35%, while 33.6% of natural gas was used, almost 30% of petroleum products and 1.4% of Coal. It should be noted that one of the characteristics of primary energy consumption is the high share of renewable energies, which represents 35.2%.
“These figures reflect, once again, the clear commitment of the Government of Aragon to decarbonisation. Apart from reflecting in consumption the practical disappearance of coal in the generation of electricity, the considerable increase in renewable energies stands out. The contribution of solar and wind power, which already constitute 35% of all primary energy consumed in Aragon, “explains the vice president and Minister of Industry of the Government of Aragon, Arturo Aliaga.
The Minister of Industry adds that these figures “are joined by a decrease in the consumption of fossil fuels and a commitment, both by promoters and consumers, to incorporate green, clean and renewable energy in manufacturing processes and consumption. Thank you To the operation of the national system, through Red Eléctrica, the more than 17,000 mw / h that Aragón produces are also distributed to other autonomies that are in deficit; in fact, three are leading this project of decarbonization of the economy and digitization and committed to the complete renewal of electricity generation through renewable sources. Aragon, with Castilla-León and Galicia, are leading this process that we are willing to consolidate and maintain “.
In absolute values, a significant change in this consumption has been its decrease, marked by the impact of COVID-19, as well as the small percentage provided by coal, which, as reflected in the figures, has decreased by 83% compared to 2019, year in which it decreased by 48% compared to 2018, after the closure of the Andorran thermal power plant in June 2020.
In relation to the degree of self-sufficiency in Aragon, that is, with the use of renewables, it increased more than six points in 2020 compared to 2019. Last year it was 35.8% compared to 29% the previous year.
The decrease in petroleum products also stands out, up to 12% compared to 2019, and the increase in renewable energies, 20% more compared to 2019, while the consumption of natural gas remains the same. One of the main reasons for this decline lies in the generation of electrical energy, since the year 2020 has significantly increased the production of wind and solar energy.
In 2020, wind energy was the renewable technology that contributed more electricity to the system and Aragón is among the three communities that generated the most electricity with the wind, along with Castilla y León and Galicia, becoming exporters of electricity. Aragon also ranks third in covering regional demand with renewable energies and only five exceed 100% of its demand with indigenous renewable resources. The surplus renewable electricity is transferred to other communities that are deficient in electricity generation through the electricity grid.
Regarding the electrical power that has been operational in 2020, the closure of the Andorran thermal power plant (1,101 MW, and that, in this way, the coal power plants in our community disappear); and the increase in renewable power (wind and photovoltaic solar) compared to 2019, which amounts to 8,396 MW divided into: cogeneration (6.1%, 512 MW), combined cycle (22.2%, 1,863 MW) , in hydroelectric (18.5%, 1,558 MW), in wind (40.6%, 3,406 MW) and in photovoltaic solar (12.6%, 1,058 MW).
With the installed power, there has been an electricity generation of 17,592,984 MWh, which represents 7.4% of the total production in Spain and which is distributed in coal thermal (1.5%), in cogeneration (20, 2%), in combined cycle (15.6%), in hydroelectric (25.4%), in wind (47.1%) and in solar photovoltaic (10.1%). Electricity generation during 2020 has been 17% higher than that corresponding to 2019.
Electric power production
In 2020 compared to 2019, the production of electrical energy from coal has decreased by 87%; in turn, combined cycles have increased by 6% and that from hydroelectric plants by 40%. Likewise, production from renewable energies has increased, in line with the increase in new installed power throughout the year. That from wind energy has also increased by 41% (and represents 47.1% in 2020 compared to 33.4% in 2019). The greatest increase was recorded by solar photovoltaic energy, up to 364% (which represents 10.1% compared to 2.2% in 2019).
The incorporation of successive electricity generation technologies and the optimal use of available resources means that in Aragon, depending mainly on the availability of the power plants and rainfall, up to twice the amount of electricity consumed. During 2020, the electrical energy exported to other regions reached 6,933,392 MWh, which represents an export of 39.4% of the total electrical energy production.
The ratios that show this specialization in electricity generation from renewable sources are exemplified by the fact that if Aragon consumed all the renewable energy it produces, it could supply around 125% of electricity consumption. Of everything that the Aragonese community generates, between conventional and renewable, 71% comes from this second source.
Another indicator of renewable energies in this autonomy to take into account, specifically wind power, is the production of electrical energy from a wind source compared to the final consumption of electrical energy in the residential, commercial and services field, which reaches 187%.
Regarding final energy consumption, in Aragon in 2020 it was 3,556 ktoe, distributed in the group of consumer sectors as follows: industry, 39.0%, transport, 29.6%, residential, commercial and services, 20% and agriculture, 11.3%. This consumption was significantly lower than in 2019, reducing to 8.29%.
It should be noted the high value of the share of energy from renewable sources in gross final energy consumption, which in 2020 exceeded 30%.
