correct way to render map with UTM Grid

What is the correct way to render a map with UTM Grid? I have tried setting up a utm_grid section in the config file but it fails to render.

# excerpt of .ocitysmap.conf
...
[rendering]
# List of available stylesheets, each needs to be described by an eponymous
# configuration section in this file.
available_stylesheets: stylesheet_osm1, stylesheet_osm2
available_overlays: scalebar, compass_rose, surveillance, utm_grid

# The default Mapnik stylesheet.
[stylesheet_osm1]
name: Default
description: The default OSM style
path: /home/jason/source/openstreetmap-carto/mapnik.xml

# Another stylesheet
[stylesheet_osm2]
name: AnotherOne
description: Another OSM Stylesheet
path: /home/jason/source/mapnik-stylesheets/osm.xml
# path: /path/to/another/osm.xml

# Bundled overlay effect stylesheets
[scalebar]
name: Scale_Bar_overlay
description: Scale bar
path: internal:scalebar

[compass_rose]
name: Compass_Rose_overlay
description: Compass Rose
path: internal:compass_rose

[surveillance]
name: Surveillance_Overlay
description: Surveillance Cameras
path: internal:surveillance

[utm_grid]
name: UTM_Grid
description: UTM Grid
path: internal:utm_grid

Render with:

./render.py --overlay='UTM_Grid' --paper-format='Din A4' --title="Ceci n'est pas Paris" --osmid=-411354

Results in:
