Energy Systems Library

Energy Systems Library (ESL) is a Modelica-based library designed to plan and optimize industrial to utility-scale energy systems (electricity/heat/hydrogen).

The variety of pre-configured models, detailed customization capabilities, and an interface to set boundary conditions enable holistic system analyses for energy system engineers working on decarbonization and green energy.

ESL allows users to perform techno-economic optimizations, including the production, storage, and consumption (purchase and sale) of electricity, heat, water, CO2, hydrogen, and other fuels.
