Dear Brilliant Open-Minded Energy Modellers: ===================================== First of — Happy Friday, secondly: =====================================
Exciting News from www.ClimateCompatibleGrowth.com
!
We’ve launched FINCoRE, a new open-source tool
and online training to estimate the cost of capital for key renewable energy technologies in 176 countries!
Built by Imperial College London, FINCoRE
supports accurate energy finance planning for solar, wind, hydro, and more in LMICs. Explore global heatmaps, country projections, and tech comparisons via our interactive webtool.
Integrate it with tools like OSeMOSYS, FINPLAN,
MINFin - and others - for smarter energy transition strategies.
Try it out and take our free OpenLearn course to dive in!
Use FINCoRE:

Hi Mark, hi Luke
Please correct me if I am wrong on any of these points. The FINCoRE application:
Regarding code publication, I only found the following on the web (and I don't think the namespace clashes are a problem):
While here, I never figured out the open status of MAED and FinPlan, both of which originated from the International Atomic Energy Agency. More background here:
Can someone help out? TIA.
I would really like to see these kind of issues resolved. The central matters for this community.
with best wishes, Robbie

It's not really my place to push the International Atomic Energy
Agency (IAEA)/OSeMOSYS community to conduct their development in
public. The URL you provided has had no code activity
whatsoever in its two-plus years of existence. And there is
strong active development elsewhere.
I checked with my open-source legal network as a precaution.
There is no technical requirement for an open-source project to
establish a community. So that sets the lower benchmark.
However the openmod was formed to promote open science and
policy transparency, which provides a much higher bar.
I tried hard to determine the status of MAED/MAED-2 on the forum
thread I mentioned. And was told that MAED was now open
source. However, the current context does not align with my
expectations for open development — and I suspect that few in
this community would describe MAED as an open‑source project.
I suggest that the OSeMOSYS community put pressure the IAEA to
adopt open development. Otherwise, this project and FinPlan
should be described as proprietary software.
I'm sorry to be so harsh, but I do feel somewhat gaslit through
this process. If there is anything I can do to support future
discussions with the IAEA in this context, I would be happy to
contribute.
with best wishes, Robbie

Hello Mark, hello all
I had hoped I could prompt efforts towards resolving the code publication and licensing strategies for the MAED‑2 (sometimes MAED) and FinPlan (sometimes FINPLAN) projects. Unfortunately that prospect, it seems, is fading. I would have preferred to work behind the scenes and have done so to some extent (as those involved will know). However I now have no real alternative but to respond directly to recent traffic on this list.
It is clear to me that the related GitHub repos for MAED and FINPLAN were established as red herrings and lack institutional backing.
Considering the current state of discussion on this list server, all I am asking is that people stand by their recent statements.
On 22 April 2025, Mark described MAED as "open source", indicated a close collaboration with the "brilliant peeps" at the International Atomic Energy Agency (IAEA), and included a link to the inactive GitHub repo.
In terms of background, some time ago, Will Usher (KTH Stockholm) wrote about the difficulty of working with in‑house legal at the IAEA.
In April 2024, Naomi Tan (Loughborough University) published
comprehensive documentation
for FINPLAN, although with no reference to a public repository or
licensing or even open source status.
I bring in these two people because Mark previously referenced
them in this regard.
The newly reworked OSeMOSYS community discussion server (planned URL) cites both MAED and FINPLAN as open source.
Perhaps those with more influence that I can push for progress with the IAEA in regards to MAED‑2 and FinPlan?
It saddens me to write these kinds of posts, no one comes out looking good, and I think our openmod community suffers a little as a result.
with best wishes, kia kaha, Robbie
