Steam Turbine Upgrades

Adds two bigger steam turbines: MK2 and MK3. They run on regular late-game steam and consume it at the same rate per MW as the vanilla turbine, so they only save space, not steam. Power output is adjustable in mod settings.

New technologies

• Steam Turbine MK2 (500 of each science pack), unlocks after:
  • Heating tower - in Space Age;
  • Nuclear power - otherwise;
• Steam Turbine MK3 (1000 of each science pack), unlocks after:
  • Steam Turbine MK2;

New entities

• Steam turbine MK2:
  • Mid-game tier;
  • Produces 60 MW by default, occupies 5x7 tiles;
  • Consumes steam in proportion to its power output, exactly like a row of vanilla turbines (~10.3 steam/s per MW);
  • Steam hotter than 500°C gives no bonus (capped at 500°C, like the vanilla turbine);
• Steam turbine MK3:
  • End-game tier;
  • Produces 140 MW by default, occupies 7x10 tiles;
  • Same steam consumption model as the MK2;
  • Steam buffer of 5000 steam (MK2 holds 2000), so it absorbs demand spikes smoothly;

Additional features

• Power output of both turbines is configurable in settings (MK2: 10-100 MW, MK3: 16-250 MW; changing it requires a restart);
• Steam consumption scales with the output setting automatically;
• Without Space Age:
  • The technology tree falls back to the vanilla branch (after nuclear power);
  • Recipes use only vanilla items;
  • In the Space Age branch the recipes also use tungsten plates;
• The MK3 recipe costs exactly 3x the MK2 recipe;
• Weighs 200 kg per unit (a full stack of 5 fits into one rocket) for MK2 and one ton (exactly one per rocket) for MK3;
• Vanilla turbine sound and smoke, tuned per orientation;

Existing saves

• Mod does not change vanilla entity or item properties;
• Safe to add to an existing save; removing the mod turns placed turbines back into errors (remove them first);
• Mod is mostly safe for using with existing save but it is STRONGLY RECOMMENDED to make backup before installing OR updating mod version;

Compatibility

• Requires Factorio >= 2.1;
• Compatibility with Factorio: Space Age is optional (recommended);
• Works well with Quality mod;
