Had an idea for a mod and need some help.

So I've got a basic idea for a mod: Add the ability for power using buildings to transport and daisy chain power.
This would allow assemblers and electric furnaces to provide power to nearby buildings.

I'm brand new to modding and watched a few tutorials but those seem to be based around adding new content to the game rather than modifying existing content.
Question is simple: How do I modify existing items to add or replace functionality or attributes.

I was even thinking of making a new technology research to allow this but I want to get the initial idea off the ground first.

Yes...but I had other ideas and wanted to work on them. Just don't know how.
