The entire global electricity grid, in an impressive interactive map that shows the evolution of the energy transition

There are few infrastructures as complex and essential to living in the world as we know it as the electrical grid, which in practice for most mortals is reduced to touching a switch or connecting a plug to the socket and it works. Behind the world’s electrical infrastructure there is a huge conglomerate of equipment, careful planning and uses that are changing (among other things, due to the now so famous data centers).

It is not the only thing that is being transformed: the energy transition is making it possible for those resources that once supplied the electrical grid to give way to renewable energies. But not all countries in the world have the same density of electrical networks or the same sources, because in fact there are real black holes in this very complete world map of the electrical network.

Is called OpenGridWorks and is an interactive map of the entire world’s electrical infrastructure, from a small solar plant to the great lines that cross continents. And we already told you that it attracts attention not only for the beauty of the chromatic compositions, but also for practical purposes: from planning an engineering project to analyzing energy policy.

This map is actually a web platform for geospatial visualization of electrical infrastructure. All its data comes from OpenStreetMap, the world’s largest open, collaborative geographic database, maintained by volunteers and experts on an ongoing basis. This guarantees global coverage, constant updating and completely free access. But for network and infrastructure data it uses information from Global Energy Monitor or the United States Energy Information Administration, among others.

Its purpose is to show, in a clear and interactive way, where electricity is generated, how it travels through the grid and where consumption is concentrated. It is worth stopping at the layers and all the information it shows because as we warned you before it is very complete, so if you leave all the options activated you will find yourself in a mess. If you move on the map and get closer, you will be able to see information such as:

  • What technology provides the energy in the form of a colored bubble: blue for hydroelectric, red for thermal, yellow for solar, green for wind and purple for nuclear.
  • The size of each bubble represents the installed capacity in MW
  • Transmission lines are drawn thicker the higher their voltage (from 100 kV to 765 kV) and substations appear as nodes where these lines converge.
  • Data centers also appear in the shape of a white diamond as they are points of intensive consumption. On the other hand, easement strips (ROW) appear as shaded areas around lines and facilities.

But you will also be able to see additional information when you hover the pointer over any of the points. An example: when touching the Montes de Cierzo wind farm in Tudela, we will see that it is in operation and the energy it provides.

What the global electrical map reveals about the energy transition

Playing with the zoom and scrolling you quickly discover that there are areas of saturation and others that are a desert of infrastructure. From an engineering point of view, the map allows you to search for the closest interconnection point for a new project or detect nodes whose failure would leave regions without supply.

Beyond engineering, it is an energy policy tool: it highlights the electrification gaps in developing countries, shows the real progress of renewables compared to fossil fuels, and allows the resilience of different national networks to be compared. AND abysmal differences are observed.

The densest networks They are concentrated in the United States, central Europe and China, while sub-Saharan Africa and central Asia show very poor coverage that reveals an electrical blackout. In South America, the areas with the most infrastructure are on the Atlantic coast, although there are also some timid points on the Pacific coast. However, inside we barely find more than a fade to black.

The colors of energy sources also change on the map, still dominated by thermal generation, although in Western Europe and China the advance of solar and wind power is a reality already perfectly visible.

This map also reveals curiosities such as that nuclear plants always appear next to rivers or coasts due to cooling needs and hydroelectric plants are concentrated in the large river systems of the world. The data centers are also not placed at random, but are clustered near large transmission nodes to ensure supply.
