A 6/min HC Valley Battery farm can use different layouts and power setups. See the listed mid-game code, its ore requirements, and how it differs from Thermal Bank designs.

Several guides document HC Valley Battery farms at 6 batteries per minute, but they describe different layouts. The mid-game Enfield Build listing for code EFO01893u5E3O61AuUI73 reports 120 Ferrium Ore/min, 180 Originium Ore/min, and a 525 kW draw. A separate GameWith design pairs the same output with Thermal Banks and reports power generation instead. Treat those as distinct configurations, not figures to combine.

Which 6/min HC Valley Battery layout should you use?

Choose based on the blueprint’s region, inputs, and power setup—not output alone. The community listing from snooflo on Enfield Build is labeled Americas/Europe and mid-game; it also describes its Sandleaf chain as self-sufficient. GameWith presents a separate high-efficiency design with Thermal Banks. The available sources do not establish all comparable details for every design.

Layout Output Reported inputs or power Code and scope
Enfield Build community listing by snooflo 6 HC Valley Batteries/min 120 Ferrium Ore/min; 180 Originium Ore/min; 525 kW draw EFO01893u5E3O61AuUI73; Americas/Europe; mid-game; posted 2026-01-24
GameWith high-efficiency layout 6 batteries/min 3,300 power generation with three Thermal Banks; 4,400 maximum with four Guide shows a separate code; last updated 2026-03-18
ConCon video-described farm 6 batteries/min Video title/description calls out 1,100 power per battery; other layout requirements are not stated in the description EFO01U4Ai1e0o8Oo37Oa8; published 2026-02-15

The Enfield Build listing gives Ferrium Ore and Originium Ore as external inputs and says the Sandleaf portion is self-sufficient. It does not publish the footprint or required tech/Authority level. The listing warns that recipe changes may mean an older code needs rebuilding.

How to import the Enfield Build code

  1. Go to an AIC Area and open the Blueprints Menu. On PC, the listing gives F1 as the shortcut.
  2. Select Import Blueprint, paste EFO01893u5E3O61AuUI73, and confirm.
  3. Save it to Shared Blueprints, then place it in the AIC.
  4. Before committing materials, check that the code imports for your region and inspect the in-game preview to confirm the layout matches what you intend to build.

The code and recipes are version-sensitive: the listing itself cautions that later recipe changes can affect older blueprints, and current in-game validity has not been established by the listing.

What the power numbers mean

The 525 kW figure is the draw shown for the Enfield Build production blueprint. GameWith’s 3,300 and 4,400 figures describe power generation from a different high-efficiency layout running three or four Thermal Banks. They use different configurations and system boundaries, so subtracting or combining them would not give a verified net-power figure.

The official factory tutorial explains that Thermal Banks generate electrical power for the regional grid. They consume Originium Ore and batteries; batteries generate more power than ore, improving Thermal Bank efficiency. Grid facilities must ultimately connect back to the Protocol Automation-Core (PAC).

Keeping the regional grid online

If PAC reserves run out, the official tutorial advises adding Thermal Banks or switching facilities off to reduce consumption. Backup Power can keep facilities running for 30 minutes after reserves reach zero, then has a 12-hour cooldown. It is a temporary buffer, not a fix for a grid whose generation remains below demand after backup ends.
