Greeting, Endministrator!
In the early stages, before batteries are available, burning raw ore is your only power source. As your base grows, so does the risk of power overload. Once production lags, the entire base collapses. Establishing a stable power grid to distant mining areas is a top priority for every Administrator.

| What is "Power Grid Expansion"?
In Arknights: Endfield, "Power Grid Expansion" refers to the process of extending the base's core power network to remote resource points by deploying Repeaters and Pylons. It is the most critical infrastructure task during the pioneering stage.
Before batteries are unlocked, the base relies entirely on burning Source Ore for power. As industrial equipment increases, power demand surges. If ore production lags, the entire power grid faces complete collapse. Connecting remote mines significantly boosts resource yields, providing a stable power source for automated production lines and advanced blueprints.
| Arknights Endfield Prerequisites for Power Expansion
Upon completing the Level 34 main storyline, the entire map of Valley IV will be accessible, marking a "graduation" phase for your infrastructure blueprints.
Before proceeding, it is essential to unlock all shortcuts within the map (such as ladders and gates) to save significant time when traveling to lay power lines.
Additionally, double-check your inventory to distinguish between Repeaters (used for transmission) and Pylons (used for powering mining areas); this prevents misplacing equipment at critical nodes, which would result in your mining drills failing to operate.
| How to Increase Power Output in Arknights Endfield?
Install a Thermal Bank
To fix power shortages, install a Thermal Bank, which can act as a power generator using Originium ores or batteries. You can increase your power by connecting the source ore directly to the generator from the base hub. It is recommended that you prioritize installing Thermal Banks in the AIC core to ensure a steady power supply.
Thermal Banks
The Thermal Bank is a facility that converts Originium Ore or batteries into electrical power. It must be connected to the power grid to work.
Use a higher-power battery
>Early Stage
Originium Ore: Produces 50 Power in 8s.
>Early - Mid Stage
LC Valley Battery : Produces 220 Power in 40s.
>Mid - Late Stage
SC Valley Battery: Produces 420 Power in 40s.
| Arknights Endfield Power Grid Tricks
Tip 1: Don’t Jump While Wiring
Wire distance is calculated based on your total movement path; jumping will waste available wire length.
Tip 2: Wire from Low to High Elevations
Based on Tip1, a higher parabolic arc (from jumping or falling) makes it easier to exceed the distance limit. It is recommended to wire from lower to higher ground, or use low jumps to compress the arc.
Tip 3: Use "Teleportation Magic" to Wire
Once you start pulling a power line, the connection is retained even after Teleporting via the map. This allows for cross-map long-distance wiring and significant length savings in specific scenarios.
Tip 4: No Distance Limit Once Connected
Once the wire is successfully connected to a node, moving further away will not cancel the connection, even if you exceed the initial placement limit.

Note: For every newly deployed node, its power source will always be the closest node that is already powered. Numerical sequences only represent the order of placement. If Node 8 is physically closer to Node 5 than Node 7, the line will draw from Node 5. In such cases, you may need to backtrack to previous nodes.
Administrator's Tip: After completing the grid, open the map interface. Powered mining zones will show a highlighted power icon. If the icon is grey, the Pylon at that mine has failed to connect to the main grid.
| Conclusion
By mastering these power layout logics and tips, you now have the foundation to achieve full automation in Valley IV. High-efficiency resource output will not only eliminate early-game power overload concerns but also provide the continuous momentum needed to reach your final infrastructure blueprints.
