The GAMS language requires a proprietary environment and its significant cost effectively limits participation to those who can access an institutional copy.
== Programming components == Programming components, in this context, are coherent blocks of code or compiled libraries that can be relatively easily imported or linked to by higher‑level modeling frameworks in order to obtain some well‑defined functionality.
=== Technology modules === A number of technical component models are now also open source. While these component models do not constitute systems models aimed at public policy development (the focus of this page), they nonetheless warrant a mention. Technology modules can be linked or otherwise adapted into these broader initiatives.

=== Auction models === A number of electricity auction models have been written in GAMS, AMPL, MathProg, and other languages. These include:
the EPOC nodal pricing model Australian National Electricity Market examples using MathProg can be found at b:GLPK/Electricity markets
=== Open solvers === Many projects rely on a pure linear or mixed integer solver to perform classical optimization, constraint satisfaction, or some mix of the two. While there are several open source solver projects, the most commonly deployed solver is GLPK. GLPK has been adopted by Calliope, ETEM, ficus, OSeMOSYS, SWITCH, and TEMOA. Another alternative is the Clp solver. From mid‑2022, the HiGHS open source solver offers another option. HiGHS is used by the web‑based version of the PyPSA European multi‑sector model Proprietary solvers outperform open source solvers by a considerable margin (perhaps ten-fold), so choosing an open solver will limit performance in terms of speed, memory consumption, and perhaps even tractability. The flexible SMS++ optimization toolbox, written in C++17, is being developed specifically to meet the needs of energy system modeling.
