A non-profit software company aiming for fast and reliable energy transition globally.
We empower energy planners and decision-makers with energy transition studies, flexible open-source platforms, and expert training and support.
Can open-source models support European TSO transmission planning?
Our latest Open-TYNDP release suggests yes: comparable outputs to proprietary tools, faster runtimes for CBA, and fully reproducible workflows.
New features include improved demand side response and load shedding, improved benchmarking, central data bucket, central carrier mapping, and faster CBA solving.

Are open-source solvers keeping up with proprietary tools on real energy models?
We're finding out on 28 May!
At “Benchmarking Optimization Solvers for Energy System Models: 2025 Results” you'll get performance comparisons between CBC, GLPK, HiGHS, SCIP and Gurobi — plus a panel on where open-source optimization is headed.
Free. Online. One hour.

It was also welcomed by the policy makers and energy stakeholders we discussed the results with. It was very impressive.
Thanks to Salvatore Fantoni and Dimitar Kolichev from Eurima for participating in this case study.

What would you an energy system study for? 4/4
Eurima has already put these insights into action through the Your Home, Our Future campaign:
• 3 policy recommendations in the light report
• 40+ meetings across the EU energy and construction sectors
• 5+ stakeholder workshops
• 6+ events presenting the findings
As Salvatore Fantoni (Sustainable Construction and Communications Manager, Eurima) put it:
"I was positively surprised by what the model could take into account when analysing energy prices and electricity costs. 🧵3/4
What we found: Flattening the peak demand curve through energy efficient buildings optimizes all aspects of the energy system, including total energy costs, emissions, and the need for generation and transmission infrastructure.
The campaign light report was focused on two scenarios and a baseline, showing how the total electricity demand is 1825 TWh lower in the 2050 scenario with widespread renovation over business-as-usual: https://www.yourhomeourfuture.eu/ 🧵2/4
€312 billion could be saved every year in Europe by making buildings more energy-efficient and flexible, our open energy study showed. But which impact did the results have?
Over 10 months in 2023–2024, Open Energy Transition conducted a study for Eurima and the International Copper Association Europe, supported by the European Climate Foundation to look at how buildings can impact the energy system. 🧵1/4
Openmod Workshop South Africa 2026 26 June 2026 • Cape Town, South Africa Openmod comes to Africa Open Energy Transition and the Energy Systems Research Group from the University of Cape Town are delighted to announce the inaugural Openmod Workshop in Africa, to be held at the University of Cape Town on Friday, 26 June 2026. Open-source energy system modelling remains underrepresented across much of Africa’s energy planning landscape. Openmod helps address this gap as a community-driven move...
