 ## Overview
 The Holistic Optimization Program for Electricity (HOPE) model is a transparent tool for evaluating electric sector transition paths regarding power system planning, system operation, optimal power flow, and market designs. It is highly configurable and modulized programming coded in the  [Julia](http://julialang.org/) language and optimization package [JuMP](http://jump.dev/). The HOPE consists of multiple modes for modeling modern power systems and electricity market, including:
 1. `GTEP` mode: a generation & transmission expansion planning model
