This is the old Lightning Rod Addon for IC², the first thing I have ever created in regards of Minecraft Mods, and the beginning of GregTech itself. It does 8 388 608 EU at a rate of 8192 EU/t once struck by Lightning, you will need 4 HV Transformers around it in order to grab all Energy it emits. Lightning Strikes happen on a random chance depending how many IC² Iron Fences you place ontop of the Main Block and on how tall the overall Rod is (Bedrock to Height Limit is most efficient). The generated Power is not subject to actual Lightning strikes, you cant just cause a Lightning Strike with a special Arrow or something, that won’t work.

mcarchive.net has quite a few older Versions of known Mods, that might fit well together.
Modrinth Archives is also archiving old Mods, maybe you find what you are looking for there.

This Mod was made by me, Gregorius Techneticies (aka GregoriusT) and is licensed under the LGPL and Creative Commons 0 for the most Parts (except Logos), so share it whereever you want, nobody is going to stop you. ;)
But I’m not responsible if you got the Mod from a place that isn’t here!
People, who non-financially contributed to the Mod are credited in the mcmod.info.
Some older GregTech Sourcecode does not exist anymore, so I cannot provide it if asked to. This makes it technically impossible to officially license those specific Versions under LGPL, but I still consider them Free to use for other purposes under the same terms GT6 has.

Just drop both of these Files into the Mods Folder after installing IC².
