> OSM contains errors and I don't know how to fix them.

The easy part of the answer to this is: go to openstreetmap.org, sign up for an account, login (top right) and then press the "Edit" button (top left). There is a lot of info[0] on their wiki on how to get started.

There is also information on how to map power lines[1] - I am guessing applying it to your specific example is what might be a bit harder, but it's probably doable.

The overpass-api tool is useful for finding objects, for example the power lines in the area that you mentioned: https://overpass-turbo.eu/s/1f6N

It's sometimes a bit fiddly, but when I very occasionally (like once a year) find something to correct, I can get it done.

Happy mapping.
