Power Node

Power Node is a power-transmitting building used to route electrical power across your base. It functions as a configurable transmitter with a range of 6 tiles and a stored power capacity of 10 units. Power Nodes are a core component of power networks: they link producers, consumers, and storage into discrete grids so you can distribute or isolate power where needed.

Power Nodes let you manually control which blocks they feed. Opening a Power Node’s interface and clicking any block within its 6-tile range will create or remove a connection between the node and that block; clicking an already-connected block removes that single connection, and clicking the Power Node interface again clears all connections. When laying out a chain of Power Nodes, the planner attempts to place them 6 tiles apart and align them in a straight line from the starting node toward the cursor, which helps build long-distance links quickly.

Power in Mindustry is measured as a rate (power units per second) and is transmitted instantaneously rather than flowing as items or liquids. Power Nodes transmit power to the closest connected block in each of their directional outputs; different transmitter types provide different numbers of directions, but a standard Power Node’s behavior centers on connecting to and supplying nearby blocks within its range. Because Power Nodes have limited capacity, they are best used to bridge networks and guide flow rather than as bulk storage; dedicated battery blocks provide larger capacity when you need to buffer energy.

Practical notes and strategies:

• Use Power Nodes to segment production and defense into separate power grids. Isolating heavy consumers (such as turrets) prevents them from starving production lines during surges.
• Plan long transmission lines by placing Power Nodes 6 tiles apart; the builder will usually align them in straight stretches if you drag while placing.
• Manually manage connections to prioritize critical buildings. Removing nonessential links can preserve power for more important machinery.
• Remember that Power Nodes only transmit to blocks within their 6-tile range and are limited by their small internal capacity; rely on generators for sustained supply and batteries for storage.
• The Power Node’s design and cost have inspired community speculation about real-world superconductors (notably LK-99), due to its apparent efficiency and lack of resistance mechanics.
