The RTG provides constant and reliable electricity for spacecraft. Its weight/power ratio is a lot worse than that of solar panels (unless you are very far away from the sun - Dres and beyond), but RTGs have the advantage that they do not require direct sunlight, so they still work when on the night side of a planet.
The Radioisotope Thermoelectric Generator is useful for purposes such as:
- Traveling so far away from the sun that solar panels become insufficient.
- Operating energy-consuming equipment on the night-side of a celestial body.
- Removing the need to take special action to replenish electrical power stores.
- Emergency backup for a stronger primary power supply.
- Providing power while stowed in a fairing or cargo bay.
The alternative when there is too little sunlight is to use fuel cells. Which one is better depends on many factors. As a rule of thumb, two RTGs useless mass than an equivalent in power single Fuel Cell after about 1.5 hours of operation while 24 RTGs win over a Fuel Cell Array after about 2 hours of operation.
|“|| Through exploitation of the natural decay of Blutonium-238, this elegantly simple power generator can provide consistent, stable power for decades. Not to be used for providing heating during emergency rover excursions.

The description contains a reference to The Martian, where Mark Watney used an RTG to provide heating in order to save power.
- There are also two parts on the w:New Horizons probe that has the same appearance in-game.
- Moved from Utility to Electrical
- Mass reduced from 0.175 to 0.08, power output reduced from 1 E/s to 0.75 E/s.
- Initial Release
