About this mod

Make Archibald proud! This mod adds the gas works, a set of buildings that allow you to manufacture gas in the Old World and Cape Trelawney.

Tired of managing arctic logistics, and prefer to manufacture gas in a more convenient manner? Running out of room for additional gas mines? Then look no further! This mod adds the Gas Works, an industrial plant that takes coal and transforms it into a flammable gas suitable for manufacturing and electrical generation. Gas works producing coal gas were the primary method that cities in Europe first got flammable gas in the 19th century, and were widespread throughout the continent—until the advent of natural gas in the mid-20th century.

The gas works functions uniquely in that the base gas works manufactures gas at a slow rate, but with each additional gasometer placed nearby, productivity rises—along with workforce requirement, running cost, and the amount of pollution generated.

The caveat though, is that with a productive plant comes high pollution and running costs—so there is a clear trade-off in comparison with Arctic gas. And of course, many of the most polluted industrial sites in our real world were gas works, so be mindful of which islands you want these buildings situated on.

GU14 Update: GU14 fixes + new UI changes by Jakob. Added strings for Taiwanese (thanks zw12356) & French + Industry Department Buffs (thanks Fuffzehn). You will need to load from a pre-GU14 save in order for this to work, or the problem will persist. This applies to all industrial mods as well!

GU16 Update: Technically no updated needed, but the opportunity was taken to add translations for all languages, and to reduce the worker workforce needed for the base building from 500 to 350.

  • You will need the anno1800-mod-loader installed, or at least an alternative version.
  • Place into your mods folder.
  • If you are experiencing issues with the graphics not appearing, place the moddinggraphics folder inside the Anno 1800\data folder.


The gasometer has three visual variations, accessible by Shift+V.

If you click on the gasometers, you will be able to see the production bonus radius limit.

The gas works should be affected by associated palace policies, working conditions, or influence bonuses. 

The gasometers can also be placed independently of the gas works as just ornamentation. 

No buffs or items affect the gasometers.

This mod contains all necessary LODs and texture sizes to ensure that it runs best on all computers!

Big thanks to fam and taubenangriff for helping me with the template needed to make the gasometers and their buffs work correctly. Thanks to Phoenīx and Robin for the playtesting, photos, and the German translation. Thanks to Fuffzehn for the industry department buff code, zw12356 for the Taiwanese translation, and Jakob for the new UI changes & images.
