We host a free monthly PyPSA support session - confidential and TSO-only - every first Monday of the month. You are invited: openenergytransition.org/projects/fre... Online | Monday 3 August 2026 | 10:00-11:00 CEST

Launching PyPSA-NorthAmerica 🚀 A #PyPSA-model based on PyPSA-Earth built by Open Energy Transition. The model provides a transparent and evidence-based foundation for decisions on generation, storage, and transmission. Decisions that matter for decades. 🔗 Try the model: github.com/pypsa-mee...

Next step: Open Energy Transition will continue the project toward a 2026 validation. Open modeling is paramount because the assumptions we make in energy planning shape how we build for the future. 📧 Newsletter: openenergytransition... 🎥 PyPSA User Meeting video: www.youtube.com/watc...

At the 4th PyPSA User Meeting, Measrainsey Meng presented the Open-TYNDP workflow: an open-source project that complements the European Ten-Year Network Development Plan (TYNDP) workflow and increase transparency. 🎥 Video: www.youtube.com/watch?v=rgQa...

The PyPSA ecosystem is growing. Congratulations to PyPSA Labs, the new independent non-profit. PyPSA's strength comes from multiple committed groups pushing it forward. Our focus remains on helping system operators, regulators, and industry move to open & improved energy planning.

New OET/ICCT study on aviation fuel: Today, conventional jet fuel costs $3/gallon. Future scenarios show how e-kerosene cost could range between $5-$8/gallon by 2040. The difference depends on the degree of climate ambition or if renewable deployment is poorly sustained. github.com/open-energy-...

Digital sovereignty needs more than open-source pilots. What do grid operators need to turn promising open energy tools into trusted operational infrastructure instead of using proprietary software? Long-term support, maintenance, and documentation?

What does #battery storage have to do with open energy planning? Read our blog post from February (but still relevant) about a Germany study on battery storage "Without transparent energy planning, the lights could go out": www.energy-storage.news/without-tran... #OpenSource #EnergyTransition

Without transparent energy planning, the lights could go out

In 2025, Germany had 2.5 GW of operational grid-scale batteries, the largest fleet in the EU 🔋 Another 10 GW is in the pipeline. Had that capacity been online in 2025, Germany could have avoided €830 million in gas purchases and solar redispatch costs. ember-energy.org/lat...

The next frontier in AI coding is not an agent writing the most code, but one that supports humans to collaborate. Cheaper code generation won't disrupt the fundamentals of software engineering. Blog below: Tobias Augspurger, Andrew Nesbitt, Richard Littauer & Max Parzen 🧵

We are looking for a Business Operations Manager. If you have Operations experience and believe in our mission of advancing the global energy transition through innovative open-source tools and data solutions for energy and grid planning, this job is for you! (link in thread)

The software behind energy planning shapes billions in infrastructure investment but much of it is closed. Open energy models can bring back #DigitalSovereignty.

If energy systems are critical infrastructure, should the open models used to plan them be treated as Digital Public Goods (DPG)? At #UNOpenSourceWeek, we discussed open-source energy models, DPG, and transparency. What do you think? #OpenSource #EnergyTransition

Batteries can’t solve the energy transition alone. AVANGUARD, a new EU-funded project on LDES with 30 partners across 13 countries, will deliver transparent, open-source analysis to help policymakers reduce risk, support investment, and strengthen energy security. What is the biggest LDES challenge?

More than 100 energy experts joined our discussion on how PyPSA is becoming a credible open-source alternative to proprietary energy modeling tools. For funders, this is investment in shared digital infrastructure for transparent, reproducible energy planning. 🎥 youtu.be/ycqdg4BekgI
