The amount of fuel a tower in EVE consumes depends on its size. There are three sizes of control towers: small, medium, and large. Small control towers use the least amount of fuel, consuming fuel units every four hours. Medium control towers use twice as much fuel as small towers, consuming fuel units every two hours. Large control towers use the most fuel, consuming fuel units every hour. The type of fuel used also depends on the type of tower, with some towers requiring specific types of fuel, such as Liquid Ozone or Heavy Water. The cost of fuel for a tower in EVE can vary, with some players reporting costs of around 90 million for 30 days of fuel for a small tower, while others report costs of around 100 million ISK per 3 months for a small corp with a modest fuel cost.

Fuel type and quantity
The fuel type and quantity required for a tower in EVE depend on the tower's size and type. Control towers come in three sizes: small, medium, and large. The larger the tower, the more fuel it consumes. Small control towers use one-quarter of the fuel of a large tower, while medium towers use half the fuel of a large tower.
The fuel types accepted by structures include Enriched Uranium, Oxygen, Mechanical Parts, Coolant, Robotics, Nitrogen Isotopes, Helium Isotopes, Oxygen Isotopes, Hydrogen Isotopes, Liquid Ozone, Heavy Water, and Strontium Clathrate. Strontium Clathrate is stored separately from other fuel types and is used to fuel the tower's Reinforced Mode, which is activated when the shields are gone. It is recommended to always have at least one hour's worth of Strontium Clathrates in the stront bay.
The quantity of fuel consumed also depends on the number of modules online. Each module consumes fuel, and turning them on and off incurs a fuel cost. It is recommended to balance the fuel load to ensure that each module has roughly the same amount of fuel supply.
The cost of fuel also varies depending on the market and the tower's location. It is possible to mine for fuel, but it is important to plan ahead and have a sufficient stockpile to avoid falling behind and risking an attack.

Tower size
The amount of fuel a tower in EVE consumes depends on its size. There are three tower sizes: small, medium, and large.
Small towers consume fuel every four hours, medium towers consume fuel every two hours, and large towers consume fuel every hour. The larger the tower, the more fuel it consumes.
The time it takes to anchor a tower also depends on its size. Small towers take 7.5 minutes, medium towers take 15 minutes, and large towers take 30 minutes.
The cost of running a tower also depends on its size. A small tower may cost around 90 million for 30 days of fuel, while a medium tower consumes 20 blocks of fuel per hour, and a large tower consumes 40 blocks per hour.
It's important to note that the type of tower and its location can also affect fuel consumption and costs. For example, faction towers use less fuel, and fuel costs can be determined by querying market data.
Additionally, towers require different types of fuel, such as trade goods and ice products, as well as Strontium Clathrates, which are used for the tower's "reinforced mode" during attacks.

Strontium Clathrates
It is recommended to put at least 8-16 hours' worth of Strontium Clathrates in the stront bay, with some sources suggesting 30-40 hours. Additionally, it is advised to keep a spare stock of Strontium Clathrates in a nearby location for quick replenishment if needed.

Fuel costs
The fuel cost for a tower in EVE depends on the type of tower and its location. The fuel cost is a critical issue and should be the most important consideration when planning a base.
Control towers come in three sizes: large, medium, and small. Large control towers have the most shields, grid, and CPU capacity, but they also use the most fuel. Medium control towers use half the fuel of large towers and have fewer shields, grid, and CPU. Small control towers use a quarter of the fuel of a large tower and have the least shield, grid, and CPU capacity. The fuel units are consumed every hour for a Large CT, every 2 hours for a Medium CT, and every 4 hours for a Small CT. For example, a medium tower consumes 20 blocks/hour, while a large tower consumes 40 blocks/hour.
The fuel required to keep a control tower online includes trade goods and ice products. Enriched Uranium, Oxygen, Mechanical Parts, Coolant, Robotics, Nitrogen Isotopes, Helium Isotopes, Oxygen Isotopes, Hydrogen Isotopes, Liquid Ozone, Heavy Water, and Strontium Clathrate are some of the specific types of fuel required. Strontium Clathrate, for instance, is used to fuel the POS's "Reinforced Mode", which is activated when the shields are completely gone, and the tower consumes fuel at a high rate to withstand damage.
The cost of running a small POS is estimated to be around 90 million for 30 days of fuel in highsec. The monthly cost for a Caldari tower is estimated to be 184M for a medium tower and 368M for a large tower. For an Astrahus with just a clone bay, the fuel cost is approximately 100m ISK per 3 months.
To manage fuel costs, it is recommended to set up a spreadsheet to track fuel costs, the fuel supply stockpiled, hourly consumption, and the amount of fuel in the tower. It is also suggested to have a one-month supply of fuel stored in advance to avoid falling behind and risking an attack.

Anchoring and setup
To anchor a tower, you need the Anchoring skill at rank I, and you will also need the starbase role from your corporation to manage the control tower. Anchoring at rank III allows for EW structure use, and at rank IV, you can train Starbase Defense Management to actively control defense structures during a siege. A player must be a member of a player-owned corporation and have appropriate roles. Additionally, the corporation must be at least 7 days old to own a POS in high-security space.
Before setting up a new POS tower, keep in mind that anchoring and putting a tower online takes a long time. Allow 15+ minutes for a small tower, 30+ minutes for a medium tower, and 60+ minutes for a large tower. You will also need a lot of time to anchor modules, especially if you have a complex setup. A corporation that is not a member of an alliance can only anchor one POS tower per day per system. However, a corporation could anchor multiple POS towers in multiple systems on the same day. An alliance can anchor a maximum of five POS towers per day per system.
Once you have settled on a location and found an empty moon, you should haul your tower to the location along with some fuel and "stront" to get the tower online. You cannot start anchoring without corresponding Starbase charters in cargo. Even one piece is enough to start the process. The tower will then be moved by the EVE server to the centre of that grid location. This can be up to 200km away from your warp-in point, so you may have to look around to find it. Anchoring time varies by tower size. Small towers take 7.5 minutes, medium towers take 15 minutes, and large towers take 30 minutes. When you anchor a tower, make a note of the EVE time and the estimated time for it to finish (or use a watch/timer). Since you can do nothing else during the tower anchoring process, you may want to warp off to a safe spot to wait out the timer.
After anchoring, you can either leave the module offline or right-click the module to put it online and active. When moving the green box with the arrows, every "step" is about 960m. Most modules need to be placed a minimum of 1920m away from the nearest module (2 steps).
The fuels needed to keep a Control Tower online are trade goods and ice products. Your Control Tower has limited space to place these fuels in. The fuel units are consumed every hour for a Large CT, every 2 hours for a Medium CT, and every 4 hours for a Small CT. Drag and drop the fuel block type appropriate for the tower into the bay. Starbase charters matching the star system sovereignty also go in this bay. Strontium Clathrates go in a separate bay, also accessed by right-clicking the tower.
Strontium supply is not used during normal tower operation; it controls how long your tower will stay in reinforced mode if it's attacked. You can adjust the amount of strontium so the timer runs out at some convenient time for you, but make it long enough that the attackers don't just hang around and finish the job on the same day. As a general rule of thumb, if you put "N" units of Strontium Clathrates in your tower, you should keep a spare stock of "N" units of Strontium Clathrates in a nearby location. That way, if the attackers leave you alone after the initial attack, you can quickly replenish the "stront bay".
