How to Host a Technical Electrical Server
Technical Electrical is a relaxed NeoForge 1.21.1 tech-builder pack focused on electrical systems, automation, and infrastructure — no punishing expert mode, just power networks, automated machines, and logistics for solo or small-group play. Hosting it well mostly comes down to not underestimating the RAM a 'relaxed' pack still needs and letting the first boot finish before you start building.
Start with 5 GB of RAM as your floor — electrical automation and logistics mods keep running machine simulations in the background even during quiet solo play, so don't undersize it just because the pack is labeled 'relaxed.'
Import the official Technical Electrical modpack from the server panel — the automation and electrical mods in this pack are chosen to work together without expert-mode gating, and swapping pieces by hand can reintroduce the friction the pack is designed to avoid.
Let the first boot finish cleanly before doing anything else — automation mods need to register their machine and power-network data before you start building on top of them.
Wait for that clean first boot before placing your first power network — building on an unfinished boot risks machines that don't register correctly.
Back up before any NeoForge update or config change — a growing automated base is exactly the kind of long-term build that's painful to lose.
Use a cleaner Technical Electrical path
CoalHost is built around modpack hosting, which makes Technical Electrical much less annoying to launch correctly.
