[Talk-GB] Solar farms from REPD, all checked

[Dan S]

Hi all,

This weekend I completed the task of going through the REPD dataset
(UK planning data) for solar farms. Out of 1058 entries, about 65 were
un-spottable,* the rest are in OSM.

We have 908 solar farm objects in OSM for the UK.
The REPD list totals about 8.1 GW and we've got approx 6.9 GW
explicitly tagged. (Plus 70 of the 908 have no capacity tagged.)

Most of the solar farms are in there as power=plant. However, there
are plenty that had previously been tagged as power=generator, and I
chose not to coerce everything into fixed format. Also, I generally
didn't trace the panels (nor even the blocks of panels) within solar
farms, I merely drew outlines. So there's plenty of scope to improve
the mapping in future!

The repd:id tag is really useful for checking back against REPD. Some
of the mapped solar farms have multiple IDs (semicolon separated),
since there are lots of solar farms which had extensions added in
later years.

As I said, there were about 65 REPD items I couldn't spot in aerials.
Funnily enough, we have a rather similar number (55) of solar farm
objects in OSM which have not been associated with a REPD entry nor do
we have any capacity tagged for them. (Here's a query for non-repd
solar farms: <http://overpass-turbo.eu/s/O9T>)

Best

P.S. my spreadsheet is still messy, but I updated it as I went, so
fwiw: http://mcld.co.uk/tmp/wiki_repd_list_dan.ods
