How to Increase Power Output in Arknights Endfield

If you’ve been playing Arknights Endfield for a few hours, you’ve probably noticed something: your factory keeps growing, but your power doesn’t. That default 200 electricity cap hits fast, and suddenly your production lines are grinding to a halt. The good news? Scaling up your power is straightforward once you know what to build.

Whether you’re new to the game or looking to optimize your setup, this guide breaks down everything you need to expand your energy production and keep your operations running smoothly. For more tips on mastering the game’s systems, check out our Arknights Endfield guides hub.

Building Your First Thermal Bank in Arknights Endfield

The key to breaking past that initial power ceiling is constructing a Thermal Bank. Think of it as your primary power generator—once you have one running, you can start scaling your factory without hitting constant energy bottlenecks.

Before you can build a Thermal Bank, you’ll need to unlock it through research. Head to the AIC Factory Plan and navigate to the Power section. Research the Power I node, which not only unlocks the blueprint but also gives you a free Thermal Bank to get started.

Crafting Additional Thermal Banks

Once you’ve unlocked the technology, you can craft more Thermal Banks as your factory expands. Each one requires:

• 10 Origocrust
• 10 Amethyst Parts

Here’s how to gather and process these materials:

For Origocrust:

• Throw 1 Originium Ore into a Refining Unit to get 1 Origocrust

For Amethyst Parts:

• Process 1 Amethyst Ore in a Refining Unit → produces 1 Amethyst Fiber
• Take that Amethyst Fiber to a Fitting Unit → produces 1 Amethyst Part

Both Originium and Amethyst ores are fairly common in the early zones, so you shouldn’t have trouble gathering what you need. If you’re still getting familiar with resource gathering and character progression, it’s worth exploring the map thoroughly.

Choosing the Right Fuel Source

Thermal Banks don’t run on good vibes—they need fuel. You have several options, each with different power outputs:

• Originium Ore: 50 Power per unit
• LC Valley Battery: 220 Power per unit
• SC Valley Battery: 420 Power per unit

Early Game Strategy

In the beginning, stick with Originium Ore. It’s abundant, easy to farm, and doesn’t require complex production chains. Sure, it’s not the most efficient fuel, but when you’re just starting out and space isn’t an issue, simplicity wins.

Late Game Considerations

Once your base gets crowded and you’re optimizing every square meter, switching to batteries makes sense. They deliver significantly more power per unit, freeing up space and reducing the number of Thermal Banks you need cluttering your layout.

That said, batteries are valuable commodities. You can sell them at the Outpost for solid profit, so there’s a trade-off between using them for power and using them for income. Weigh your options based on your current needs—if you’re flush with resources but tight on space, batteries are the way to go.

How to Craft Batteries in Arknights Endfield

If you decide batteries are worth the investment, here’s the production process for both types:

LC Valley Battery

This mid-tier battery requires a bit more processing but offers a decent power boost:

1. Originium Powder: Shred 1 Originium Ore in a Shredding Unit → 1 Originium Powder
2. Amethyst Fiber: Refine 1 Amethyst Ore in a Refining Unit → 1 Amethyst Fiber
3. Amethyst Part: Process 1 Amethyst Fiber in a Fitting Unit → 1 Amethyst Part
4. LC Valley Battery: Combine 5 Amethyst Parts + 10 Originium Powders in a Packaging Unit → 1 LC Valley Battery

SC Valley Battery

The high-end option delivers maximum power but demands more resources:

1. Originium Powder: Shred 1 Originium Ore in a Shredding Unit → 1 Originium Powder
2. Ferrium: Refine 1 Ferrium Ore in a Refining Unit → 1 Ferrium
3. Ferrium Part: Process 1 Ferrium in a Fitting Unit → 1 Ferrium Part
4. SC Valley Battery: Combine 10 Ferrium Parts + 15 Originium Powders in a Packaging Unit → 1 SC Valley Battery

Building efficient production lines for these batteries takes planning. If you’re also managing team compositions and character builds, balancing factory automation with combat readiness becomes part of the strategy.

Tips for Efficient Power Management

• Plan ahead: Don’t wait until you’re completely capped out to build more Thermal Banks. Research and craft them proactively so you’re ready when expansion hits.
• Automate fuel production: Set up dedicated production lines feeding your Thermal Banks automatically. This keeps power flowing without manual intervention.
• Monitor your grid: Keep an eye on how much power each section of your factory consumes. Understanding stats and systems helps you optimize placement and avoid bottlenecks.
• Sell excess batteries: If you’re overproducing batteries, selling them at the Outpost can fund other upgrades and gacha pulls.
