Alliander and open source

Alliander aims to provide customers with timely solutions by 2030, contributing to the accelerated development and sustainability of the Netherlands. In this pursuit, digitalization is of crucial importance. Digitalization cannot exist without open source software. Alliander not only uses open source software but also actively contributes to its development and makes internal software available as open source where it is of strategic value. However, what exactly does open source entail?

What is open source?

Open source software is characterized by a source code that is freely available, accessible, and adaptable for everyone. In open source projects, developers from various companies collaborate to work on a software project together. This not only promotes the exchange of knowledge and the sharing of costs, but it also stimulates innovation and acceleration. For Alliander, participating in open source projects represents a form of co-creation and collaboration with partners. 

Allianders open source approach 

When working with open source software, there are various approaches available. One option is to simply use existing open source software without making any contributions. Another, more active approach involves using open source software while simultaneously applying one’s own knowledge and skills to contribute to the further development of this open source software. Additionally, one can initiate an open source software project by open-sourcing internal software. Alliander employs all these approaches. Besides making extensive use of open source software, Alliander also actively contributes to various open source projects. Furthermore, Alliander has made some of its internal projects available as open source. This allows others to not only use this software but also contribute to it. By investing in an open source ecosystem, Alliander contributes to the development of relevant software. This software helps Alliander provide timely and efficient solutions to its customers by 2030 at the latest, a significant step towards the sustainability of the Netherlands. 


We enjoy working with other parties on projects that advance us both. You can read more about this below, or contact us via

Power Grid Model example

One open source project that Alliander actively uses and maintains is the Power Grid Model. Alliander has developed the Power Grid Model to create conceptual representations and simulations of electrical power grids. It enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability. 

The Power Grid Model finds applications in various areas, including grid planning, expansion, reliability, and congestion studies. Additionally, it can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization. Notably, the Power Grid Model outperforms similar tools in terms of its performance capabilities.
