Good afternoon. 

Why did you change the name of this substation (https://www.openstreetmap.org/way/116434364) from "Davao Substation" to "DavaoCity_Substation"? The name tag should contain the actual locally used name with proper spacing and no special symbols like underline. 

Also descriptive names like this one here (https://www.openstreetmap.org/way/1373308965) should not be added. It's okay to leave name tag empty for obects that don't have a proper name.

Lastly, please don't just comment every upload with "detailing". Changeset comment should contain a brief description of the edits that you made. It's also very hepful if you mention your sources, e.g. ground survey if you visited a place in person.

Thank you.
