Oh hold on, wait. It's open source. We offer **everyone** a free licence for PyPSA. That's the point. Everyone, regardless of background and means, should be able to model the transformation of their energy systems, see what the code is doing, and modify it if need be.

Energy Exemplar has blocked all TU Berlin students from academic licences for their energy modelling tool PLEXOS because competitor PyPSA is developed here. While deeply shocked, we believe in turning the other cheek. So we are offering all Energy Exemplar employees a free licence for PyPSA.

There are open-source alternatives to PLEXOS like our own PyPSA:

github.com/pypsa/pypsa

Besides costing nothing, open source gives you the freedom to inspect and modify the code.

🇨🇦 Canada's ambitious plan to double its electricity demand by 2050, supplied by clean energy, is at least partly based on Canadian studies done with PyPSA @pypsa-org.bsky.social. 🇨🇦
Electricity is one of Canada’s biggest opportunities. Here’s how we’re seizing it:

Python for Power System Analysis (PyPSA) now has an official social media channel - follow for feature deep-dives, releases and other updates!
Hello, World! Hello, Bluesky!
PyPSA is now officially on Bluesky - it took a couple of years and a major version release, but we're finally here!

🚨 New paper: Coupling integrated assessment and energy system models 🚨

Planning future energy systems requires bridging two fundamentally different scales: long-term transformation pathways spanning decades, and short-term power system operations unfolding hour by hour.

Pretty petty of Energy Exemplar…

This further highlights the value and importance of open source models like PyPSA.
Energy Exemplar has blocked all TU Berlin students from academic licences for their energy modelling tool PLEXOS because competitor PyPSA is developed here. While deeply shocked, we believe in turning the other cheek. So we are offering all Energy Exemplar employees a free licence for PyPSA.

If you want to build and run a PyPSA (pypsa.org) network with little programming knowledge, give Table PyPSA a try!
You can build the network from an Excel table, and it returns main outputs in an Excel table. Especially suitable for teaching and stylized analyses with limited network complexity.

PLEXOS is the modelling tool for the EU grids Ten Year Network Development Plan. What if they switched to PyPSA?

This just makes me more interested in PyPSA than anything else I've ever seen.

Have to imagine this is a direct result of the Blackstone acquisition.

Thanks Hannah! Here are the slides if anyone is interested:

Although I realised too late they're missing a crucial model description slide🤦, I'll add it it soon. But it's PyPSA-Eur, all energy sectors, net-zero CO2 emissions, default of 200 MtCO2/a sequestration.

By better design and operation 𝐚 𝐭𝐡𝐢𝐫𝐝 of the planned network development cost (~€90 bn of the proposed €283 bn) in Germany could be saved

...according to @nworbmot.bsky.social & team, based on PyPSA modelling in the new @ariadneprojekt.bsky.social report.

Agentic AI is surely the Killer App of open energy modelling - just watching the agents play with @pypsa-org.bsky.social workflows, it's hard to imagine how closed suites can compete.

The @pypsa-org.bsky.social ecosystem will remain open-source and co-maintained by multiple institutions, providing strength in diversity. PyPSA Labs will take over the lead on core maintenance tasks for PyPSA and PyPSA-Eur from TU Berlin over the next year.
