Attention Alpha clones!
Omega clone state.png Planetary Interaction is significantly more profitable on an Omega due to skill requirements. You can make a setup on one planet with limited skills however. In addition, Gallente is preferable due to the Epithal having a special cargo bay for PI materials.

An Epithal importing PI materials

Planetary Interaction (PI) allows pilots to develop colonies on most planets in the Eve universe. You can either extract raw PI materials from the planet or process PI materials through a series of processors. The aim of this is to produce a range of commodities which can be used in blueprints for manufacturing purposes (e.g. Fuel Blocks which are used by Citadels).

Why do PI

It is an easy way to make passive ISK. You simply create a supply-chain that connects extractors to processors to launchpads. Once configured, all you need to do is import/export the PI to/from the planet. Depending on the amount of effort you want to place in, this can require daily monitoring or weekly monitoring.


  1. Interplanetary Consolidation - Allows you to develop more planets (Preferable to go to IV. V is not necessary but can help)
  2. Command Center Upgrades - Allows you to set up more infrastructure on one planet (IV is essential if you wish to make a passive income)
  3. Planetology - Shows you more accurately where planet resources are concentrated (Optional)
  4. Advanced Planetology - Same as Planetology (Optional)
  5. Remote Sensing - Allows you to scan planets from 'x' light years away (Optional)
  6. Customs Code Expertise - Reduces the NPC tax rate of Player Owned Customs Offices (POCOs) in high sec (Optional)

PI Basics

Types of PI Material

This is an example of the requirements to make fuel blocks

There are 5 levels of PI materials in game.

  • R0 - These are your resources that you extract directly from the planet using an extractor.
  • P1 - These cannot be extracted from the planet but rather are created by converting P0 into P1 on the planet using a processor.
  • P2 - These cannot be extracted from the planet but rather are created by converting P1 into P2 on the planet using a processor.
  • P3 - These cannot be extracted from the planet but rather are created by converting P2 into P3 on the planet using a processor.
  • P4 - These cannot be extracted from the planet but rather are created by converting P3 into P4 on the planet using a processor.

Resources (R0) -> Tier 1 Products (P1) -> Tier 2 Products (P2) -> Tier 3 Products (P3) -> Tier 4 Products (P4)

Please note: Each tier higher also uses up less volume (m3). This is important when transporting PI.

Planetary Buildings

For more details, see Planetary Buildings

To extract and produce resources and products you need buildings! Buildings match the planet they are constructed on, but players only need to worry about selecting the right type of command center, the rest are built in-place on the planet and thus always of the right type. Each building beyond the Command Center costs a set amount of Powergrid (PG) and CPU. At a glance, the following structures exist:

Type Description
The primary building that you must construct to get started on PI on a planet. You can deploy from anywhere undocked in space including while being tethered. Once placed, you can upgrade command center providing more CPU and Powergrid per level. Can store a small amount of material and offers a simple rocket launch mechanism by which you can ship said materials to orbit.
Extractor Control Units Extractor Control Units (ECUs) allow installation of extraction programs and the building of extraction heads. In the extraction programs have to pick the resource type for all heads, a duration of the program (up to 14 days), and must provide a route for the raw material to travel once extracted, lest it be lost. It is suggested that you always connect the output of an extractor to a storage.
Extractor Heads Extraction of resources is done by extractor heads that are installable via the ECUs. The heads can be placed within the ECUs area and can be moved via drag and drop to resource hot-spots for a greater extraction amount.
Processors These come in three different types, Basic (used to transform raw materials (P0) to processed materials (P1)), Advanced (used to either transform processed materials (P1) in refined commodities (P2) OR refined commodities (P2) in specialized commodities (P3)), and High Tech (used to transform specialized commodities (P3) in advanced commodities (P4)). The latter can only be built on barren or temperate planets.
Storage Facilities A building dedicated to the storage of materials or goods, potentially as part of a larger logistics system. It is suggested that you maintain storage sites or launchpads between outputs of extractors and processors and inputs of processors.
Launchpad A building dedicated to moving materials and goods to and from the planet. Similar in function to the rocket launch function of the Command Center, but superior as it is connected to a customs office in orbit above the planet, from where the owner can import and export goods. This is the primary way to export and import PI. It is suggested that you maintain storage sites or launchpads between outputs of extractors and processors and inputs of processors.
Planetary Links These can essentially be thought of as railroads, connecting different structures. In addition to being built (which has a base cost plus a distance cost) actual routes have to be defined using the links to route specific products across your planetary network. They have a finite capacity in m3 per hour and can be upgraded. The smaller the radius of the planet, the smaller its cost. It is suggested that Industrial planets that do not extract resources are placed on smaller planets in order to reduce the CPU/Power costs of these links.

Additional Information and Tools

For more information on Planetary Interaction go to the Eve University wiki. Eve university also has a great page about what commodities can be processed into.

Another great source of information but is somewhat outdated is this guide.

There are more sources of information available online, so remember, google is your friend.

Some great tools for helping you design and manage your PI are the following:

  1. Evegadgets - Helps you plan out how many extractors, processors, etc.. can be built until you reach CPU/Power limits.
  2. Eve University PiBear - I use it mainly to help you identify which system has what planets so you can plan your PI production.
  3. Eve Planets - Same as PI bear. Just another website to help plan where to build. Also provide PI schematics
  4. Alysii PI - Helps show production lines between different PI levels and what planets are required.
  5. Fuzzwork PI - Great tool to help you determine what is most profitable to make.
  6. Adam 4 Eve - Advanced tool to understand market industries. WARNING: Once you enter this rabbit hole, you may not escape the clutches of eve.

PI Example Templates


The key to making the most out of your CPU and Power is to keep buildings right next to each other as the longer the links, the more cpu and power they use. Here are some examples:

P0 - P1 Production


P0 - P2 Production (24 hr set-up) - WARNING: You might burn out

P0P2 24.png

P0 - P2 Production (48+ hr set-up) - Credited to Canadianartichoke



There are many different configurations. Below are only a few. The key is to use a planet with a small radius and ensure the links are right next to each other.
