This guide covers how to set up and improve your power grid. You can start with a simple layout and work your way up to a large industrial system. These designs keep your base running and help you make extra money.

The First Thermal Battery

Once you get the Thermal Bank, aim for 200 power. You can set this up near the AIC Core or the Bus Depot. Start with an output for Originium Ore. Place a belt three blocks long. Put a Splitter at the end. Place another Splitter between the bottom two Thermal Banks.

You want four Thermal Banks with their arrows pointing away from the source. The Originium Ore will fill the first two banks quickly, then the rest. It might jump around at first, but it stays steady once the banks are full.

Mid-Game 660 Power Setup

To reach 660 power, you need Originium Ore and Amethyst Fiber. Place Shredding Units in front of the Originium Ore to get Originium Powder in Arknights: Endfield.

Use a Fitting Unit to turn Amethyst Fiber into Amethyst Parts. Power these with an Electric Pylon. Set up a Packaging Unit to take the items from the belts. Put three Thermal Banks right in front of the packager to catch the batteries.

To save the leftovers, use a Protocol Stash. Put a Splitter on the bank closest to the stash and another pointing left to move extra batteries into storage.

The 840 Power Build

This version gives 840 power and extra batteries to sell. You need two Ferrium Ore sources. Put two Shredding Units in front of the Originium Ore and two Fitting Units on the left for Ferrium Parts. Place an Electric Pylon on each side.

Put the Packaging Unit in the middle. Place two Thermal Banks and a Protocol Stash below it. Connect the Ferrium Ore to the Fitting Units and the Originium Ore to the Shredding Units in Arknights: Endfield.

Send it all to the packager. Use a Splitter to send half the batteries to the first bank. Add two more Splitters to keep the second bank from running out. The rest goes into the Protocol Stash.

The 1,100 Power Industrial Build

The largest setup gives 1,100 power but uses six lanes and a farm. Build a Sandleaf Farm using a Seed Picking Unit, Planting Unit, Shredding Unit, and Protocol Stash.

Let the farm fill up with plants before you connect it to anything else. Half the output must stay on the farm to keep it going. For the main power plant, put Ferrium Ore through Shredding Units, then into a Grinding Unit with Sandleaf Powder.

Use a Refining Unit to make Steel and a Fitting Unit for Steel Parts. At the same time, mix Originium Ore and Sandleaf Powder in another Grinding Unit. Send everything to the Packaging Unit in Arknights: Endfield.

Use Splitters to push the parts in. Use more Splitters at the end to feed the Thermal Bank. Send 25% of your batteries to the Protocol Stash. You can sell these HC Valley Batteries for 70 credits each.
