Alternating Flux NeoForge
by Arctonix
Alternating Flux extends Immersive Engineering with a high-voltage transmission tier that carries power over spans standard wires cannot reach.
What it does
Alternating Flux adds an AF wire tier for moving bulk power across large distances. AF wires can span up to 96 blocks per span, a value that is configurable, while Immersive Engineering's high-voltage wires top out at 32 blocks and need relays placed close together. Losses along an AF line are far lower than on standard wires, and the transmission carries up to 131,072 IF/t, four times the throughput of modern high-voltage wiring.
An AF line is a transmission backbone only. AF power cannot run machines directly, so it is stepped down through an AF Transformer at the source end, with a high-voltage low side and an AF high side that converts 1:1. A second transformer at the far end steps the power back to high voltage for machines. Constantan Wire is used to craft the AF Wire Coil, and AF Wire Relays on towers carry the coil between them.
Alternating Flux requires Immersive Engineering, and it is published for Forge and NeoForge across five game versions, 1.16.5 – 1.21.1. The NeoForge build is for 1.21.1, and the latest files are 1.0.6. Installation covers the server and each player's game. The license is custom and the mod is not open source, though public source code exists.
Key features
Long-range AF wires
AF wire spans reach up to 96 blocks each, with the span length set in the configuration.
Low transmission loss
Power lost over distance is far lower than on standard Immersive Engineering wires.
High throughput
The AF line carries up to 131,072 IF/t, four times the throughput of modern high-voltage wiring.
Substation-style transformers
An AF Transformer steps AF power down to high voltage at each end, so machines run on the step-down side.

How it compares
More Immersive Wires is open source under the MIT License, with Forge and NeoForge builds for 1.18.2 – 1.21.1, and it is also a client and server mod. Solar Flux Reborn covers Forge and NeoForge for 1.9.4 – 1.21.4 under All rights reserved, and is not open source. CircuitSim is a Forge-only, open source option for 1.20.1 – 1.20.6 under the GNU General Public License v3.0 only.

What the author says
Alternating Flux adds a long-distance, low-loss "super high voltage" power tier to Immersive Engineering, built for hauling power across large distances. Think of it as the transmission backbone of your grid: bulk power across distance on AF lines, stepped down to HV/MV/LV to actually use.
