The main alternative to ExaPowerIO is PowerModels.jl, a monolithic repository which:

• parses and processes Matpower as well as PTI files
• exports formulations for various ACOPF problems
• includes tools to help solve these problems. Developers wishing to utilize only 1 or 2 of these utilities may find PowerModels bloated.

ExaPowerIO.jl due to its focused nature has superior performance to PowerModels. As seen, ExaPowerIO outperforms PowerModels by a factor of 30 to 40 in both allocation and timing.
