Electricity is an essential part of our daily lives. We rely on it to power our homes, offices, and industries. Have you ever wondered how electricity arrives in Sardinia? Let’s take a closer look at the journey of electric power supply on this beautiful Mediterranean island.

Where does Sardinia get its electricity from?

Sardinia is not a self-sufficient island when it comes to electricity production. It relies on a combination of local power plants and imports from mainland Italy to meet its energy needs. Let’s explore these sources in detail:

  • Local Power Plants: Sardinia has a number of power plants that generate electricity using various sources. The main ones include thermal power plants fueled by coal and natural gas, hydroelectric power plants utilizing the island’s water resources, wind farms harnessing the strong Mistral winds, and solar power plants capitalizing on its sunny climate.
  • Mainland Imports: Sardinia is connected to mainland Italy through an underwater power cable. This interconnection allows electricity to be imported from the mainland when local production falls short. The cable has a capacity of 1000 MW, ensuring a reliable supply during peak demand periods or in case of emergencies.

How is electricity transmitted within Sardinia?

Once the electricity is generated or imported, it needs to be transmitted efficiently to different parts of Sardinia. The transmission process involves the following steps:

  • Step 1: Generation/Importation: Electricity is generated at power plants or imported through the mainland interconnection, as discussed earlier.
  • Step 2: High-Voltage Transmission: The electricity is then stepped up to a high voltage for efficient transmission over long distances. This is done using transformers.
  • Step 3: Substations and Transformers: The high-voltage electricity is transmitted through a network of transmission lines to various substations located across Sardinia. At the substations, transformers step down the voltage to a lower level suitable for distribution.
  • Step 4: Distribution: From the substations, the electricity is distributed to consumers through a network of distribution lines. These lines run underground or overhead, depending on the location and requirements.

What are the challenges of electric power supply in Sardinia?

While Sardinia has made significant progress in ensuring a reliable power supply, it faces some challenges. These include:

  • Island Grid: Being an island, Sardinia’s power grid is not interconnected with other grids, making it vulnerable to disruptions in case of faults or extreme weather conditions.
  • Reliance on Imports: Sardinia heavily depends on electricity imports from mainland Italy. Any issues with the interconnection, such as cable damage, can affect the island’s power supply.
  • Environmental Impact: Although Sardinia is investing in renewable energy sources, it still relies on fossil fuels for a significant portion of its electricity production. This has environmental implications and the island needs to accelerate its transition to cleaner energy sources.

Electricity arrives in Sardinia through a combination of local power plants and imports from mainland Italy. The transmission process involves high-voltage transmission, substations, and distribution lines. While Sardinia faces challenges in terms of its island grid, reliance on imports, and environmental impact, efforts are being made to ensure a sustainable and reliable power supply for the island’s residents and industries.
