Energy of a Warframe is a resource used mainly to power abilities. Warframes have 4 abilities that at base, cost up to 100 energy to cast. Almost every Warframe has their own energy-pool with varying capacities depending on the types and costs of their various abilities, with the exception of HildrynIcon272 Hildryn which has no energy but uses shields instead.

Like health and shields, a Warframe's energy capacity scales with their rank and through the use of mods or buffs. It is also worth noting that the words "power" and "energy" are often used interchangeably by members of the community.

Increasing Energy Capacity


These are the only mods currently in the game that increase energy capacity. It is worth noting that Mod TT 20pxFlow and Mod TT 20pxPrimed Flow cannot be used together. Mod TT 20pxAuxiliary Power only works on Archwings.

Formula For Modded Energy Capacity

These mods increase the energy capacity of a Warframe with the following the formula:

$ \text{Energy}_{total}=\text{Energy}_{max}+(\text{Energy}_{base}\times \text{Mod Multiplier}) $

So taking Volt Prime as an example, with 200 base energy and 300 max energy he will have:


The only buff currently available to increase energy capacity is Cephalon Suda's Entropy effect. Entropy will release a 25-meter AoE radial attack around the player, dealing 1000 Magnetic b Magnetic damage and applying the Magnetic Status Effect to enemies in range, increasing damage dealt to their shields. It will also restore 25% of the player's base Energy, and provide a (base) Energy boost of +25% for 30 seconds.

Arcane Helmets

These are retired helmets that in the past used to grant increased energy capacity to their respective Warframes.

Warframe Starting Energy


This is the only mod currently in the game that increases the starting energy of a Warframe.


Warframes have a fixed amount of energy that they start any mission with, and also when reviving from death. This amount of energy is calculated based on the Warframe's free mod capacity and a base value specific for each Warframe (differs even between normal and prime variants). The formula followed is:

$ \text{Starting Energy}=\text{Initial Energy}+5(\text{Free Mod Capacity}) $

When Mod TT 20pxPreparation is equipped, the formula becomes:

$ \text{Starting Energy}=\text{Initial Energy}+(5\times \text{Free Mod Capacity})+(\text{Energy Total}\times \text{Mod multiplier}) $

Note: This does not apply for Sanctuary Onslaught, where energy is reset to a nominal level (EX: 125 for Nova and Volt) when entering each portal. In this environment, the Preparation effect is lost to the energy level reset.

Table of Initial Energies

The initial energy of a Warframe is given from the following table. It is still unknown whether these values are calculated off of some other attributes or simply fixed parameters for each Warframe, and are subject to change. This area of research is still very actively worked on.

Effective Energy Capacity

Casting Effective Capacity

Similarly to how one can define the concept of "effective health" by weighting the number of hit-points with the corresponding damage reduction, one can also define the concept of casting effective energy capacity by weighting the energy capacity using the Ability Efficiency factor:

$ \text{Effective Energy Capacity}_{casting}=\frac{\text{Energy Capacity}}{2-\text{Ability Efficiency}} $

Since casting efficiency is currently capped at 175%, the highest possible upper-bound for the casting effective energy capacity is:

$ \text{Effective Energy Capacity}_{casting}\leq 4\times\text{Energy Capacity} $

Toggle Effective Capacity

Since the efficiency of toggle abilities depends also on the duration, in that case the formula becomes:

$ \text{Effective Energy Capacity}_{toggle}=\frac{\text{Energy Capacity}\times\text{Ability Duration}}{2-\text{Ability Efficiency}} $

For the case where no energy is recovered and a constant rate of energy is drained, one can also consider the effective toggle duration as follows:

$ \text{Effective Toggle Duration}=\frac{\text{Effective Energy Capacity}_{toggle}}{\text{Base Drain Rate}} $

$ \text{Effective Toggle Duration}=\frac{\text{Energy Capacity}\times\text{Ability Duration}}{\text{Base Drain Rate}(2-\text{Ability Efficiency})} $

$ \text{Effective Toggle Duration}=\frac{\text{Energy Capacity}}{\text{Modified Drain Rate}} $

Due to the definition of the terms, there are many ways in-which the formula for effective toggle duration can be expressed.

Apart from toggle duration, this can be used to work out the effective duration granted per energy pick up.


Suppose a Prowl130xDark Prowling IvaraIcon272 Ivara has a modded drain of 0.25 energy/sec. An orb of 50 energy would provide:

$ \frac{50}{0.25}=200\text{ seconds} $

Considering the same Ivara with full energy pool of 744 capacity, she can remain in prowl for:

$ \frac{744}{0.25}=2,976\text{ seconds}\approx 50\text{ minutes} $

Restoring Energy


Energy does not naturally regenerate over time, except when the Mod TT 20pxEnergy Siphon aura mod is equipped by at least one member of the squad. Otherwise, energy must be restored either by picking up an Energy Orb (and Health Orbs with Mod TT 20pxEquilibrium) or by a few other means. TrinityIcon272 Trinity and HarrowIcon272 Harrow are the two Warframes with an inherent ability to explicitly restore energy to all Warframes within the squad, and NekrosIcon272 Nekros can Desecrate130xDark Desecrate nearby corpses for a chance to drop more Energy Orbs. LimboIcon272 Limbo has, and grants, access to the Rift Plane, a dimension in which Warframes regenerate energy over time consistently. The Zenurik Focus tree grants the Energy Pulse and Energizing Dash abilities; the former being a passive that restores additional energy over-time when picking up Energy Orbs, and the latter being an added effect for Void Dash which makes it create a dome that restores energy over-time to all Warframes that walk through it.

Besides the Entropy effect from Cephalon Suda, the Blight effect from Red Veil also restores 25% of the player's base energy, and provides a base movement speed boost of +10% for 30 seconds. Squad Energy Restores are consumables that can grant energy to nearby teammates in varying amounts, up to 400 total. When using a Prime Warframe, moving close to a Death Orb will cause it to release a radial wave that restores 250 energy to all nearby Warframes within a small radius, this effect can only occur once per orb.

It is important to note that on most occasions, toggled abilities disable energy generation from team abilities, consumables, or passive regeneration methods. Some exceptions to this are ChromaIcon272 Chroma (SpectralScream130xDark Spectral Scream and Effigy130xDark Effigy) and partially EquinoxIcon272 Equinox (PacifyProvoke130xDark Pacify & Provoke and MendMaim130xDark Mend & Maim).



Equinox's Passive

When EquinoxIcon272 Equinox collects Health Orbs, 10% of the restored amount is converted into additional Energy.

  • Picking up Energy Orbs also restore Health.
  • This effect stacks with Mod TT 20pxEquilibrium for up to 120% conversion.

Using Energy as Health


These mods stop lethal damage by allowing hits to drain your energy after your Health is depleted in exchange for occasionally staggering the player. They synergize extremely well with Mod TT 20pxRage and Mod TT 20pxHunter Adrenaline since all the health drained before taking lethal damage would ensure that there is enough energy for the mods to consume.
