The Power API is a community-lead specification for an power monitoring and control API that supports small scale to extreme-scale systems. It is associated with the Energy-Efficient High Performance Computing Working Group (EEHPCWG) and also with the Exascale Computing Project (ECP). A community specification as well as a reference implementation of the Power API can be found on their website, https://pwrapi.github.io.

Upcoming goal for the Variorum team includes supporting relevant platform- and node-level APIs from the Power API community specification.
