Hello OpenEMS community,
there is a EU [1] research call on “Creation of a standardised and open-source peer-to-peer energy sharing platform architecture for the energy sector” (HORIZON-CL5-2023-D3-03-05, innovation action, proposals to be submitted by 10 Oct 2023 [2], project execution during 2024-2027 if the bid is successful). We have a rump consortium for basic technologies and also some users, but expansion is possible into the following directions:
(1) users: an objective of the call is that the open-source energy sharing platform will be usable by e.g. citizen energy communities, so if you are one (and by virtue of being on this forum, you are open-source interested), that could be a good match. But also if you do services for energy communities/prosumers or energy trading in general, your contribution might be a good addition.
(2) technology integrators and supporters: while most of the core building blocks as such are covered, this could be a good match for anyone being interested in the topic to help communities and users with support and integration (and, as side-effect, to deepen your OpenEMS + peer-to-peer energy sharing platform expertise), this also could include (if you are interested) potentially standardization and policy-making
Do not be shy, speaking frankly, any partner not from Germany will improve the geographical balance 
If potentially interested, you are welcome to either answer here in the forum, or contact me directly.
Best,
Holger Blasum, Innovation Scout for Consolinno Energy GmbH Regensburg, Germany, h.blasum@consolinno-partner.de , +49 174 7313590
