What Types of Renewable Energy Exist and What Role Do They Play in Society?
Have you ever wondered how the energy you use every day reaches your home? From its generation to the point of consumption, electricity travels a long path involving different players within the electrical system.
In this process, i-DE, as the entity responsible for electricity distribution, ensures that energy reaches millions of homes and businesses with safety, continuity, and efficiency.
Everything begins at generation plants, where different sources —such as solar, wind, hydroelectric or nuclear— produce electricity on a large scale.
The energy producers, meaning the companies or facilities responsible for generation, inject this electricity into the grid while meeting the technical requirements needed to ensure its quality. Once generated, the energy is stepped up to high-voltage levels to make long‑distance transmission easier and reduce electricity losses.
To answer the question how electricity is distributed: from generation plants, electricity travels through large high‑voltage transmission lines until it reaches electrical substations, where the voltage is regulated and adapted to the needs of the distribution network.
At this intermediate stage, electricity moves from the transmission grid to the distribution grid, where its journey continues toward transformer centers and, ultimately, to supply points. This structure ensures that energy reaches homes, businesses and industries continuously and reliably.
Once the energy reaches the transformer centers, its voltage is reduced from medium‑voltage levels (typically 20 kV) down to low‑voltage values (230 V or 400 V), which are used in homes, businesses and industries.
Electrical transformer centers are therefore a key link in the system: they make it possible to adapt electricity for everyday use and ensure a stable supply.
Learn more about how low‑voltage distribution works: Transformation and distribution of energy.
In the final stage of its journey, electricity travels from the transformer centers to each supply point, adapting to the needs of homes, businesses and industries.
At this stage, i-DE ensures a safe and efficient connection between the electricity grid and indoor installations, guaranteeing that energy reaches consumers with the quality and continuity required for everyday use.
If you need to start the process of connecting to the electricity grid, here you will find all the information to activate your electricity supply for the first time or to increase the capacity of an existing connection.
The evolution of the electricity system is moving toward a more flexible model, where distributed generation and self-consumption play a highly relevant role. This helps reduce losses and make better use of renewable resources available in each area. In this new decentralized generation model, electricity grids shift from having a passive role to an active one in energy management.
The consumer is no longer just a recipient but also a generator. Thanks to self-consumption, each user can produce part of their own energy, reduce their bill, and contribute to the sustainability of the system.
Technological progress has turned the electricity grid into an intelligent infrastructure. Real-time monitoring and process automation improve efficiency and supply quality.
At i-DE, we work on innovative digitalization and smart grid projects that make this transformation possible.
The electrification of consumption is an opportunity to move toward a more sustainable energy model, reducing emissions and fostering the use of renewable energy across all sectors.
The growth of self-consumption, electric mobility, and renewable generation makes continued investment in infrastructure essential.
Tools such as the Generation Capacity Map and the Consumption Capacity Map help identify where connection opportunities exist.
Renewable energy sources are the driving force behind this change, and the electricity grid is the structure that makes it possible. Thanks to investments in smart grids, electricity can now flow more efficiently, safely and sustainably, accelerating the transition toward a decarbonized energy model.
At i-DE, we work to ensure that the distribution grid is ready for the new challenges of the electricity system. We facilitate the connection of new supply and self-consumption points, promote electrification, and support new, more sustainable energy models.
Because the future of energy is built from the grid, and at i-DE we continue moving forward to make it possible.
