Generator
generator
Powers lights, appliances, and refrigerators within a 20-tile radius and 3 floors up or down. Refuel with gasoline while it is off. Running it inside a building you occupy drains your health fast.

About the generator
A generator restores electricity to a building after the grid shuts off, powering lights, appliances, and crucially refrigerators and freezers within its area of effect. In Project Zomboid it is the backbone of long-term food preservation and quality-of-life once the power dies. It runs on gasoline, must be connected, turned on and maintained, and its exhaust rapidly drains the health of anyone inside the same building while it runs.
Placement & defense tips
- ▸Place the generator close enough that your refrigerators, freezers, and key appliances all fall inside its powered radius, since coverage is centered on the unit.
- ▸Run it outdoors or in a separate ventilated outbuilding to avoid the indoor carbon monoxide death risk, then site your fridges in the adjacent room within range.
- ▸Keep it away from the perimeter where its constant noise could draw zombies toward a wall section, or wall off the generator area separately.
- ▸Stockpile gasoline nearby (in a safe spot, mindful of fire) so refueling is quick and you never let powered freezers thaw.
- ▸Centralize your power-dependent gear (cooking, fridges, lights) in one cluster so a single generator covers everything instead of needing multiple units.
Choosing a variant
- ▸Build 42 has four generator models (Lectro-Max, Premium Technologies, ValuTech and Old) that differ in weight, noise and how fast they wear, so a quieter, sturdier unit is worth hauling home if you find one.
- ▸Quantity matters more than tier: a second generator can cover a separate building or a large base where one unit's radius doesn't reach all your appliances.
- ▸Generator condition affects reliability (at 20% or below it can catch fire or explode), so prioritize the best-condition unit, repair it with scrap electronics, and note you need Electrical 3, the Electrician or Engineer occupation, or the How to Use Generators magazine to connect it.
- ▸If you only need a small fridge cluster, one well-placed generator is more fuel-efficient than spreading several across the base.
Common mistakes
- ✕Running the generator inside the building you're using, where its exhaust drains your health fast until you leave or switch it off.
- ✕Placing fridges or freezers outside the generator's effective radius, so food spoils even though the generator is running.
- ✕Letting it run out of gasoline unnoticed, thawing a freezer full of stored meat and losing the food.
Frequently asked
Is it safe to run a generator indoors?
No. Its exhaust quickly drains the health of anyone inside the same structure, and the building stays unsafe until the generator is switched off. Place it outdoors or in a separate outbuilding you don't occupy, then keep your fridges within its 20-tile radius.
How far does a generator's power reach?
It powers appliances within a radius around the unit, roughly on the order of 20 tiles. Cluster your refrigerators and key devices near it so they all stay within range.
What does a generator power?
It restores electricity to lights, stoves, microwaves, and refrigerators/freezers in range, keeping perishable food cold. It needs gasoline and a connection to the building to work.
