Welcome to the osJMM Energy System Model.

Background: The Joint Market Model (JMM) is an energy system model that has been used for over 10 years by various European research groups and in the industry. The model has its roots in the WILMAR project, an EU-funded project coordinated by the RISOE National Laboratory in Denmark. This report documents version 3.1 of the JMM, which is the first open-source release. The open-source version has been almost completely rewritten, while retaining many features of the original model. The current documentation also follows, to some extent, the documentation of the first model version* but has been thoroughly revised and rewritten to describe the current version.

Objective: The JMM has a clear focus on the operational market and system operation in the electricity market with high shares of renewable energy. It also includes detailed modeling of district heating and combined heat and power (CHP) plants as well as demand-side flexibilities. Key features of the JMM include a rolling planning approach that allows for the modeling of the arrival of information such as forecast updates and a detailed modeling of various markets, including an approach for modeling "flow-based" market coupling and other market coupling approaches currently existing in Central Western Europe.
