LF Energy, the open source foundation under the Linux Foundation, wrapped up 2025 with its strongest momentum to date, signaling a growing role for open collaboration in the modernization of global energy systems.
From expanded governing board leadership to record-breaking event attendance across three continents, LF Energy’s year-end update underscores a clear trend: open source software is becoming critical infrastructure for grid resilience, interoperability, and the energy transition.
Open Source Momentum in Grid Modernization
Over the past year, LF Energy has continued to position itself as a neutral, collaborative home for digital energy infrastructure, bringing together utilities, vendors, researchers, and policymakers to solve systemic challenges such as vendor lock-in, data silos, and fragmented standards.
According to Alex Thornton, Executive Director of LF Energy, 2025 marked the foundation’s most impactful year so far, driven by:
- Rapid growth in membership across industry, academia, and research
- Increased adoption of LF Energy projects by real-world utilities and vendors
- A surge in global participation across LF Energy summits and seminars
This momentum reflects a broader shift in the energy sector: digital transformation is no longer optional, and open architectures are emerging as the preferred path forward.
New Members and Expanded Governing Board
LF Energy welcomed new associate members from research and academic institutions, including:
- Centre for Net Zero
- Institute of Communication and Computer Systems (ICCS)
- Junia
At the governance level, the foundation expanded its board with senior leaders from major technology and energy players:
- Andy Chu (Apple)
- Laurent Boinot (Microsoft)
- Naresh Kumar Gajendran (Shell)
Their participation reflects growing confidence from global enterprises in open source as a strategic enabler of energy system innovation.
Key Project Highlights in 2025
LF Energy’s technical portfolio also saw significant progress, with new platforms launched and existing projects reaching key maturity milestones:
Semantic Energy Framework (SEF)
A new framework designed to address closed platforms, incompatible protocols, and vendor lock-in, enabling semantic interoperability across heterogeneous energy systems.
RTC-Tools
A widely used open-source Python package released under LF Energy to support optimization of water and energy systems, helping operators manage complex assets more efficiently.
p-SWAMP (Power Stability WAMPACS)
A research and development environment for Wide Area Monitoring, Protection, and Control, built on earlier Nordic early-warning initiatives to enhance transmission grid stability.
SEAPATH 1.2
The latest release improves installation, networking, and storage capabilities for virtualized digital substations, accelerating real-world adoption.
FlexMeasures 0.30
Enhanced forecasting support enables multiple simultaneous forecasts and real-life analytics, improving operational decision-making for energy flexibility.
OperatorFabric, CoMPAS, and OpenSTEF
Continued releases strengthened interoperability, situational awareness, and forecasting accuracy, with documented utility and vendor deployments across Europe and the Nordic region.
Notably, real-world case studies from EcoPhi and Sigholm demonstrated how LF Energy projects are already being deployed at scale, from substation virtualization to large-scale thermal energy forecasting.
Record-Breaking Global Events
LF Energy’s community growth was mirrored by unprecedented engagement at its events:
- LF Energy Summit Europe (Germany) saw nearly 50% attendance growth year-over-year
- The inaugural LF Energy Summit North America in Quebec brought together utilities, researchers, and developers
- A strong debut at Enlit Europe (Spain) highlighted industry demand for practical open-source grid solutions
- The first LF Energy Seminar in Japan marked growing interest across Asia
These gatherings reinforced a key takeaway: energy professionals are actively seeking shared platforms to co-develop the digital foundations of the energy transition.
Why This Matters for Climate Tech
For climate-tech founders, investors, and policymakers, LF Energy’s 2025 trajectory offers a clear signal:
- Open source is moving from experimentation to production-grade deployment
- Grid resilience, interoperability, and data transparency are now strategic priorities
- Collaboration across utilities, hyperscalers, startups, and academia is accelerating innovation faster than proprietary approaches
As energy systems become increasingly software-defined, foundations like LF Energy are emerging as critical conveners of the digital energy ecosystem.
Looking Ahead to 2026
LF Energy has indicated that new investments, strategies, and initiatives are already being planned for 2026, with the goal of accelerating innovation at the pace required for the global energy transition.
For the climate-tech ecosystem, LF Energy’s continued growth reinforces an important message:
the future of energy is open, collaborative, and software-driven.
