This mod adds a Lightning Generator. It is quite costly to build, yet produces an enormous amount of power, which can help ease performance issues caused by power generation in the late game.

Frequently asked

Does Mekanism:Lightning Generator work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Mekanism:Lightning Generator declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Do I need to install Mekanism:Lightning Generator on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which platform or loader does Mekanism:Lightning Generator support?

NeoForge. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for Mekanism:Lightning Generator?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What licence is Mekanism:Lightning Generator under?

MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install Mekanism:Lightning Generator?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Mekanism:Lightning Generator safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.

Works on the same versions

Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.

Details from Modrinth, where the author last updated it on 4 Oct 2026. We do not host files or republish descriptions. Available download links point to the author’s own release.
