Used to cast Warframe Abilities and can be replenished during missions.

—In-game Description

Energy of a Warframe is a resource used mainly to cast 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 exceptions of HildrynHildrynIcon272.png Hildryn, who has no energy but uses shields, and LavosLavosIcon272.png Lavos, having no energy but instead using a cooldown system.

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 FlowMod TT 20px.png Flow and Primed FlowMod TT 20px.png Primed Flow cannot be used together. Auxiliary PowerMod TT 20px.png Auxiliary Power only works on Archwings, and Adrenaline BoostMod TT 20px.png Adrenaline Boost in Conclave.

Formula For Modded Energy Capacity[]

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

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 DamageDmgMagneticSmall64.png 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[]


These are the only mods currently in the game that increase the Starting Energy of a Warframe in their respective gamemodes (PvE and PvP, respectively).


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:

When PreparationMod TT 20px.png Preparation is equipped, the formula becomes:

Note: When entering a conduit in Sanctuary Onslaught, a Warframe's energy is reset to their respective Initial value (see below), regardless of mods or mod capacity.

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:

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

Toggle Effective Capacity[]

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

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:

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 ProwlProwl130xDark.png Prowling IvaraIvaraIcon272.png Ivara has a modded drain of 0.25 energy/sec. An orb of 50 energy would provide:

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

Restoring Energy[]


Energy does not naturally regenerate over time, except when the Energy SiphonMod TT 20px.png Energy 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 EquilibriumMod TT 20px.png Equilibrium) or by a few other means. TrinityTrinityIcon272.png Trinity and HarrowHarrowIcon272.png Harrow are the two Warframes with an inherent ability to explicitly restore energy to all Warframes within the squad, and NekrosNekrosIcon272.png Nekros can DesecrateDesecrate130xDark.png Desecrate nearby corpses for a chance to drop more Energy Orbs. LimboLimboIcon272.png 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 ChromaChromaIcon272.png Chroma (Spectral ScreamSpectralScream130xDark.png Spectral Scream and EffigyEffigy130xDark.png Effigy) and partially EquinoxEquinoxIcon272.png Equinox (Pacify & ProvokePacifyProvoke130xDark.png Pacify & Provoke and Mend & MaimMendMaim130xDark.png Mend & Maim).

Energy Reduction[]

Currently, doing a Sortie mission with the Energy Reduction condition is the only way to reduce a Warframe's Total Energy capacity (this also reduces passive regeneration effects, like Energy SiphonMod TT 20px.png Energy Siphon and Zenurik's abilities).

There are also some instances where a Warframe's energy can be expended and/or stopped from regenerating. Nightmare Mode's Energy Drain condition slowly depletes the energy pool throughout a mission. On top of its regular effects, a Magnetic DamageDmgMagneticSmall64.png Magnetic proc will consume a considerable amount of energy over its duration and prevent any type of energy restoration. In Conclave, No Current LeapMod TT 20px.png No Current Leap nullifies passive energy regeneration in exchange for increased mobility.

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 RageMod TT 20px.png Rage and Hunter AdrenalineMod TT 20px.png Hunter Adrenaline since all the health drained before taking lethal damage would ensure that there is enough energy for the mods to consume.
