Combined with refinery research, they can contribute a significant fraction of resource income on large maps. In practical terms, they boost resource income more than 45% locally, if at planets with allegiance less than 100% (which thus have a base extraction rate of less than 0.40/second). They are also not increased by research that increases extractor output (but are increased by TEC Cargo Hold research).īecause refineries are not impacted by allegiance, they are an effective counter-ploy for boosting the resource income of an expanding empire suffering from low allegiance. So don't worry about allegiance or bonuses when placing refineries. Refineries are not subject to allegiance, and they are also not affected by planetary bonuses that increase resource income (Expert Miners and Roiders Outpost).(Tested and confirmed for up to 17 extractors.) One way the 10 ships do appear to matter is that you will not receive the full income from a refinery until all 10 ships have appeared at it it takes 25 seconds for each one to spawn. If the number of local and adjacent extractors exceeds 10, the refinery continues to get 0.06 credits/second per additional extractor, regardless. Apparently these 10 ships are mainly for show. Each Refinery can serve an unlimited number of extractors (sending one ship to each of the extractors), even though technically refineries are defined as having 10 ships.Thus, if you have 3 refineries, you can increase its output by 45% (.18/.40). The base income rate of an extractor is 0.40 resources/second.If there are more than 3 (4 for neutrals), the extras are superfluous and don't provide any more income. You can see how many refineries are servicing a particular extractor by holding your cursor over the extractor. There can be a maximum of 3 refineries servicing each extractor, or 4 refineries for neutral extractors.

If the extractor is neutral (at a UCGW), the refinery earns 0.08 resources/second (a third more). Each refinery earns 0.06 metal or crystal per second for every "regular" extractor (at one of your planets).It's important to understand how they work, to optimize your income: TEC Orbital Refineries send refinery ships to extractors at the local planet and all directly adjacent gravity wells (one jump away).
