Meeting Assets
Antitrust Policy Notice
Linux Foundation meetings involve participation by industry competitors, and it is the intention of the Linux Foundation to conduct all of its activities in accordance with applicable antitrust and competition laws. It is therefore extremely important that attendees adhere to meeting agendas, and be aware of, and not participate in, any activities that are prohibited under applicable US state, federal or foreign antitrust and competition laws.
Examples of types of actions that are prohibited at Linux Foundation meetings and in connection with Linux Foundation activities are described in the Linux Foundation Antitrust Policy available at linuxfoundation.org/antitrust-policy. If you have questions about these matters, please contact your company counsel, or if you are a member of the Linux Foundation, feel free to contact Andrew Updegrove of the firm of Gesmer Updegrove LLP, which provides legal counsel to the Linux Foundation.
Agenda
- Opening and General Updates
- New Project Proposal: EnerGNN #753

Notes
John Mertic called the meeting to order at 8:04 am PT and Yarille Ortiz recorded the minutes.
Opening and General Updates
Mertic reviewed the antitrust policy and introduced the meeting agenda.
Mertic reviewed the TAC and SIG review calendars and project pipeline.
Security Audit Prioritization #408
Mertic shared that the TAC has an ability to fund up to five Security Threat Model Assessments in 2026 with room for two more. Boris Dolley said he would confirm Dynawo’s interest and Hugo van der Zwaag would add this as a topic at the upcoming Shapeshifter TSC meeting.
Annual Review Reformat #798
Mertic proposed a change to the annual review process to manage the heavy schedule of upcoming reviews, noting that the SIGs, while initially created for this purpose, no longer sufficiently address the volume. Mertic said he hopes to preview the new format beginning June-July 2026. The proposal involves:
- Reducing the presentation time from 25–30 minutes to 15 minutes.
- Requiring projects to submit a presentation to the TAC one week before the meeting.
- Using the meeting time for a summary presentation and Q&A session.
- Note - reviews for projects looking to change lifecycle stage will remain at full length.
Project Onboarding Video #797
Mertic presented a video, developed with assistance from Gemini, designed to guide prospective projects and address common inquiries. He requested the TAC members review the video and offer their feedback. The video link is available here.
New Project Proposal: EnerGNN #753
Balthazaar Donon presented the EnerGNN project, an open-source graph neural network library designed for complex energy systems, highlighting its ability to handle hyper-heterogeneous multi-graphs and real-life data discrepancies. He explained the library’s key features, including its use of Jax and Flax, and demonstrated its application in various use cases such as contingency screening and voltage control. Donon highlighted ongoing collaborations with universities and expressed openness to new use cases, model improvements, and community contributions.
Donon explained that the project focuses on data representation and GNN implementations rather than specific use cases, allowing for potential applications in various domains including power systems.
The TAC agreed to vote to accept the proposed project at the sandbox stage following the meeting via LFX.
Annual Review: Shapeshifter #136
Hugo van der Zwaag presented the annual review for Shapeshifter, which implements the Universal Smart Energy Framework for flexibility forecasting, offering, ordering, and settlement processes. He highlighted that the project has been stable over the past year with consistent contributor participation, though there has been a decrease in commits due to no major protocol updates. He said the project is currently focused on improving documentation and exploring new use cases for congestion management in the Netherlands to increase adoption among grid operators. Van der Zwaag proposed staying in the incubator stage for 2026, with plans to professionalize work on involvement and aim for early adoption in 2027.
Annual Review: LFE-SEF #132
Milenko Tosic presented the LF Energy Semantic Energy Framework project annual review. He noted that LFE-SEF originated from the Horizon 2020 Interconnect project and is now being developed under the Linux Foundation for Energy. Tosic stated that the project is currently between milestones 1 and 2, with the technical committee working on redesigning the existing source code and defining the architecture suitable for the Linux Foundation for Energy. The TAC inquired about collaboration with other LF Energy projects, to which Tosic confirmed they plan to test interoperability enablers with other projects and build new use cases for validation.
Marketing and PR Updates
Dan Brown shared updates on upcoming meetups and the LF Energy Summit in Berlin. Brown encouraged TAC members to submit proposals by May 25th and to consider organizing meetups around the event.
Closing and Next Meeting
Mertic presented the agenda for the next meeting of the LF Energy TAC, scheduled for 12 May 2026 at 8:00 a.m. US Pacific Time/11:00 a.m. US Eastern Time/5:00 p.m. Central European Time.
