[OSM-talk-fr] Earth electrode line of HVDC SACOI near Lucciana on Corse

[Philippe Verdy]

Look at the aerial photographies of the French official Geoportail:

You can easily see the electric stations. But no cables getting out of
it to the coast.

So most probably the lines are underground through the coastal
mountains up to the sea. Note also that you can see the result of
underground works on the coast. I don't know if this vertical line
joining the ground to the small rocky beach is the effective location
where the cables have been placed, but I suspect the line you also see
under the coastal water level is the presence of the cable, burried
and by some protecting infrastructure.

The locations given in Wikipedia are then loking correct for me. But
may be a Corsican resident may try to look at this location if this is
really an electric station (with DC/AC converters to interconnect it
to the regional French grid).

You may also check the other location to the North of Corsica with the
aerial photos given by the French Géoportail.

> according to http://web.archive.org/web/20051115115248/www.transmission.bpa.gov/cigresc14/Compendium/SACOI.htm , there should exist a 9 kilometres long overhead line, constructed like a 20 kV line, but using two conductors, which connects the Corse ground electrode of HVDC SACOI ( location unknown) with the converter station of Lucciana ( coordinates: 42°31′40″N 9°26′59″E ).
>
> However on no satellite pictures available in the internet, this line, which is in spite of its smallness as part of HVDC SACOI ( http://en.wikipedia.org/wiki/SACOI ) from great importance, is not visible.
>
> Why? Are all available pictures so bad? Or was the line in the proximity of Lucciana converter station undergrounded?
>
> Has someone more information? It would be great, if a mapper on Corse could find out the location of the ground electrode of HVDC SACOI and map the electrode line, which connects it with the Lucciana converter station.
