The lights flickered, plunging half of my base into darkness. Production ground to a halt, and a chill of anxiety ran down my spine. I knew that if I couldn’t fix the power situation in Arknights Endfield, my entire operation would collapse.
Power in Arknights Endfield is directly linked to your base’s efficiency, so increasing capacity is always a priority.
Initially, the default capacity of 200 power seems adequate. But as your base grows, it will quickly become insufficient. Low power will shut down your base. Let’s examine how to break past the 200 power limit and continuously improve your base’s capacity in Arknights Endfield.
Power Up: Thermal Banks in Arknights Endfield
Think of your base as a small town. Without enough electricity, factories close and homes go dark. The key to boosting your base’s power capacity is to research and construct a Thermal Bank. You’ll gain access to the Thermal Bank after playing through the initial hours of the game.

Thermal Banks require fuel, but they significantly increase your base’s power capacity. Placing your first Thermal Bank will exceed the default 200-power limit. By adding more Thermal Banks, you can further increase your power. However, you’ll need a steady supply of Originium Ore to fuel them. Consider Originium as the lifeblood that keeps the lights on.
Building Blocks: How to Construct a Thermal Bank in Arknights Endfield
I once saw a master craftsman meticulously assemble a complex clock. Each piece was critical to the whole. To build a Thermal Bank, you must first learn it from the Basic AIC Plan II. Advance through the main story until you access the second Basic AIC Plan. From there, you’ll need to learn the Power I node upgrade.

After that, you’ll be able to build Thermal Banks and place them in your base.
Again, keep your Thermal Banks well-fueled. If they run out, your base and all its structures will stop working the moment the power drops. This can cause a cascading failure.
What happens when my Arknights Endfield base runs out of power?
When your base runs out of power, production stops, defenses go down, and your progress grinds to a halt. It’s a vulnerable state, so always monitor your power levels and ensure a steady supply of Originium Ore.
Can I automate Originium Ore collection in Arknights Endfield?
Yes, automating Originium Ore collection is highly recommended. Focus on building resource collection structures and assigning Operators with relevant skills to keep your Thermal Banks running without constant manual intervention.
Are there alternative power sources in Arknights Endfield besides Thermal Banks?
Currently, Thermal Banks are the primary method for increasing base power capacity beyond the initial limit. Keep an eye on future updates, as the developers may introduce alternative power sources.
