EsSecondary school students in Huelva, Soria, Ávila and Albacete have won the 2025 Entreredes Olympics. The IES Guadiana in Ayamonte (Huelva) won in the 1st year of High School category; the IES Antonio Machado in Soria won in 2nd year of High School; IES Jorge Santayana in Ávila won in 3rd year of High School; and IES Bodas de Camacho in Munera (Albacete) won in 4th year of High School.

This year, more than 54,000 students from 11 autonomous regions (Andalusia, Aragón, Asturias, Cantabria, Castile-La Mancha, Castile and León, Extremadura, La Rioja, Madrid, Murcia, and Navarre) and the autonomous city of Ceuta participated in Entreredes, an educational project by Red Eléctrica (the Redeia company responsible for transmitting electricity and operating the Spanish electricity system). The project aims to educate high school students about the Spanish electricity system and the energy transition in an engaging, dynamic, and interactive manner.

Among its objectives, Entreredes also wants to stimulate students' interest in energy, innovation, technology, and their connection to the environment, biodiversity, and people’s well-being and to guide them towards scientific and technological careers (the so-called STEAM subjects) to build a more sustainable, fairer, and more inclusive future.

Entreredes utilises three resources: a video game, an Olympiad, and an exhibition. In the video game, students virtually explore the country along several power lines and substations in the electricity transmission grid while players answer questions from six different subjects: Energy Transition, Geography and History, Physics and Chemistry/Biology: Mathematics, Language and Literature, and Leisure and Culture. Thus, students not only learn how the electricity system works but also review the curriculum content covered in class.

The Entreredes Olympiad entails playing the video game, first at the regional level, where the schools representing each autonomous community qualify, and nationwide, which is the competition held today. 

Lastly, Entreredes invites schools to visit the 'Connected to the Future' exhibition, an interactive and digital experience designed to promote understanding of the energy transition and the active role that consumers will play in the future. In 'Connected to the Future,' students learn about renewable energies and their contribution to the energy mix, the interconnections with other countries, and how electricity is transmitted from the Spanish peninsula to the Balearic Islands—questions that arise during game-play in Entreredes.
