TESLA

Tesla gives mods a common way to move power between items, blocks and entities. Its interfaces are built on Forge's capability system, which lets a mod add Tesla support to a block such as a vanilla furnace without bundling extra code or relying on a workaround. Energy values use longs rather than integers, so the API can carry much larger power numbers. One Tesla is equal to one Redstone Flux (RF).

The API was made as a side project and drew attention from other developers, and its author describes it as a deliberate alternative to existing power APIs rather than an attempt to replace them all. It enforces a small set of standards that mod authors are encouraged to follow, and the logic stays in capability methods so tile entities implement the sided interfaces directly. Mods that depend on Tesla declare it through Forge's optional soft dependency annotation.

Tesla is open source under the MIT License and runs on client and server. Files are published for Forge only, across 10 release versions 1.9 – 1.12.2, and the latest file is 1.0.63 for 1.12.2, released on 2023-06-07. Bundling the API inside another mod is allowed but discouraged, and the author does not officially support it.
