The image produced by the program seemed unbalanced because Japan’s southernmost islands were included even though they are not part of the electrical grid. I used an image editing program to remove the outlines of those islands and shift the main part of the country toward the center.
Side comments:
Not indicated on the map is the fact that Japan’s electrical grid runs at 50 Hz in the eastern and northern parts of the country and 60 Hz in the west:

The electrical power distribution system is now undergoing a major redesign:

I was thinking of printing one that's like the California example (https://github.com/open-energy-transition/grid2poster/blob/m...). Where do people print posters nowadays?
San Francisco has a power line going to it via the underwater "Trans Bay Cable (200kV DC)" from Pittsburg. I'll have to look that up as that's quite an engineering feat in my opinion.
If you select a powerplant, wind farm or solar project, you can see how much power is generated in MW. It lists battery projects as well like the one in Moss Landing (182.5 MW). It's enlightening to compare how much power each type of generator provides, especially if they're located near each other.
Fun find: The Apple Campus's solar power output is 14.4 MW. There needs to be more of these around.
Really educational link, thanks!
For north america also look at this https://geovizzydesigns.myportfolio.com/electricity-grid-of-... , more complete only in the US since not rely on OSM
Directly under the image of electrical grid connections in Africa is the caption:
Grid2Poster supports countries, states, provinces and continents, as well as predefined regions.I wondered if there might come a time in the somewhat near future, where people would decide to disconnect from the grid for good, eventually resulting in large parts of the electrical grid becoming unnecessary (possibly alongside related jobs) and being removed.
I then ran a calculation on our own electricity use vs. production, and came to my senses. Still, personally, I think it would be great if it became possible one day. Just really unsure how it would, based on our own data.
But some people probably won't want to pay for that flexibility. If utility costs keep going up and local generation and storage costs keep going down, there's likely a point where utility power becomes undesirable for many. Unfortunately this probably increases costs for those still using utility power.
