I mapped quite intensively the photovoltaic plants and updated the wiki:
https://wiki.openstreetmap.org/wiki/India/Powerplants
Available data sources:
- Reports of the government (MNRE)
The data are problematic:
-
For exact mapping a lot of informations are missing
-
there is no clear distinction between constructed powerplants and those which are planned or under construction
- geojson file, which are the result of KI-trained software
-
the used sat images are old (till 2021)
-
a lot of plants could not be found
- newspaper articles
Here I found only informations about proposed or planned powerplants
Finally I scanned the ESRI sat images to find all plants >about 5MW.
ESRI sat images in India are about 1 to 2 years old.
Results of mapping:
-
2145 photovoltaic powerplants
-
each plant has in the tag description the total generator area(m²).
Total generator area of all plants = about 65 000 ha.
The capacity values of the plants are reliable only for the biggest powerplants. All other values have to be checked. Approximately 1MW capacity needs about 1 to 2ha generator area.
I made a table of planned / under construction powerplants.
Here a lot of works has to be done in the future.
