Our vision is to accelerate the energy transition, making it faster, more affordable, and reliable by empowering energy planners with open-source software and open data solutions.
We conduct research, develop open-source tools, and provide training to inform decision-making and address energy planning challenges. Founded in 2023, we have grown into a fully remote team of 50+ people across 21 countries. Our team includes award-winning researchers and experienced energy modelers, united by a culture of transparency and collaboration. Registered in Germany, we are committed to building solutions for a sustainable global future.
We aim to make open source the standard in energy planning by 2030. Ambitious, yet possible.

Our Core Values
At Open Energy Transition, we have 6 main values that guide everything we do. These serve as the foundation of why we are here and how we have an impact on society.
Transparency
We strive to be as forthcoming with information as possible, with open, fluid communication channels, and clear feedback that travels in all directions. In this way, we remain internally aligned, and aligned with our clients and partners, such that we all have the opportunity to learn and grow.
Collaboration
OET is a fully independent organization, consisting of autonomous and self-managed individuals. However, collaboration is core to our identity. We are willing to work with anyone who shares our vision, and internally foster a culture of collaboration across roles, Teams, Departments, and projects.
Humility
We try our best to always remain modest. And, even if we know we are the best at something, to always remember that someone else might have a great idea we did not think of, and that their input is still valued. We are all about open discussions, continuous growth, open-mindedness, mutual respect, and being humble about our achievements.
Autonomy
OET team members are highly skilled, with many holding PhDs. Team members have a very high level of autonomy. We give them the freedom to do what they do best.
Trust
We trust our partners, our clients, and our team members inherently. We are building an open-source ecosystem, which requires many different organizations and people to play their part. This can only happen if we trust each other.
Recognition
We make a point of publicly and privately voicing our appreciation contributions and successes – whether mutual or individual. Across our teams, our culture is about uplifting one another, celebrating our wins, and giving credit where it is due.
Our Theory of Change: Driving Global Impact
At Open Energy Transition (OET), we transform global energy planning by promoting the use of open-source models and data. Our focus is on creating a global impact through promoting transparency, flexibility, accessibility, and collaboration in energy planning. Here's our theory of change:
The Challenge
The traditional 'black-box' modelling approach in energy planning lacks transparency and slows down the global energy transition. Furthermore, there are challenges in getting open-source tools adopted in companies due to the lack of support and software requirement gaps.
Goal
Our goal is to address these challenges and accelerate the global energy transition. We aim to make energy planning more transparent, accessible, and collaborative, and to make open-source tools more adoptable for companies, thus driving a global impact.
Our Approach
- Facilitate Standardization of Open Data. We promote the creation and use of robust, open datasets that can be used in energy system models.
- Advance Open-Source Planning Tools. We facilitate technical advancements in OS tools and support development of enterprise-grade tools to software maturity.
- Provide Reliable Support. We offer reliable support for the use, scalability and security of the open planning solution to increase utility and trust for users.
- Build Credibility and Regulatory Support. We build credibility and regulatory support for OS grid planning tools and scale the adoption for industry and regulatory decisions.
- Expand User and Developer Community. Bolster the pool of analytical talent to collaboratively improve tools, expand the base of users who can integrate and apply these tools.
Outputs
- Increased number of studies using open data and increased open data quality.
- Increased number of users and downloads of the open-source tools.
- Increased number of companies and institutions adopting open-source tools for energy planning.
- Increased number of energy planning studies created using the open-source tools.
Outcomes
- More robust and sustainable energy systems.
- Increased public acceptance of energy infrastructure upgrades.
- Lower costs of the whole energy infrastructure.
- Increased adoption of inclusive open-source tools.
Impact
Ultimately, our work will lead to more companies around the world adopting open-source tools for energy planning. This is how we aim to create a global impact.
