Powering the Grid of the Future: SUSE Commits to LF Energy’s SEAPATH Project

We are thrilled to announce that SUSE is officially committing to the SEAPATH (Software Enabled Automation Platform and Artifacts (THerein)) project, hosted by LF Energy.

As a pioneer in enterprise open source solutions, SUSE has always believed in the power of community-driven innovation to solve the world’s most complex technical challenges. Today, there is perhaps no challenge more critical than the global energy transition. By joining forces with the LF Energy ecosystem and contributing to SEAPATH, we are taking a significant step toward modernizing the power grid, accelerating decarbonization and building a more sustainable future.

The challenge: modernizing the edge of the grid

The energy sector is undergoing a massive transformation. The shift toward renewable energy sources like wind and solar, combined with the rise of decentralized energy resources (like EVs and home batteries), is placing unprecedented stress on traditional power grids.

Historically, power substations – the critical nodes that manage and distribute electricity – have relied on proprietary, single-purpose hardware appliances. This closed-ecosystem approach results in vendor lock-in, slow upgrade cycles and massive operational complexity. To handle the dynamic, bidirectional power flows of the modern era, grid operators need agility. They need to digitize and virtualize the substation.

Enter SEAPATH

SEAPATH is an LF Energy initiative designed to answer this exact need. Its mission is to develop a reference design and an industrial-grade, open source real-time platform that can run virtualized automation and protection applications inside power substations. By decoupling hardware from software, SEAPATH enables utility companies to consolidate multiple physical devices onto a single, robust server platform at the edge.

Why SUSE is committing to SEAPATH

Our decision to commit engineering resources, expertise and strategic support to SEAPATH is rooted in a perfect alignment of technology and vision. Our engineering teams will be actively contributing to the upstream project, focusing on optimizing the real-time operating system layer, hardening the virtualization stack, and ensuring seamless edge management capabilities.

• Deep Expertise in Mission-Critical Edge Computing: Power substations demand absolute, zero-downtime reliability. To virtualize these critical edge nodes today, we leverage SUSE’s battle-tested foundation of KVM, real-time Linux, and clustering for high availability and deterministic performance. Simultaneously, we are already delivering the future: our SUSE Edge portfolio, anchored by lightweight Kubernetes (K3s), seamlessly bridges this virtualized present to a fully cloud native, containerized grid, unlocking unprecedented operational agility at scale.
• A Legacy of Real-Time Linux: Electricity waits for no one. Grid protection relays require microsecond response times to prevent catastrophic failures. SUSE has decades of experience engineering SUSE Linux Enterprise Real Time (SLERT), providing the deterministic performance, hyper-low latency, and high availability that the SEAPATH platform requires to safely operate physical grid infrastructure.
• Uncompromising Security for Critical Infrastructure: Cyber-physical systems like the energy grid are prime targets for attacks. Moving to a virtualized, software-defined model requires a zero-trust approach from the silicon to the application layer. SUSE brings enterprise-grade security, secure supply chain practices, and automated lifecycle management to ensure the grid remains resilient against evolving threats.
• Breaking Vendor Lock-in and Securing Digital Sovereignty: True digital sovereignty requires absolute control over critical infrastructure. Just as SUSE empowered the IT and telco industries to break free from proprietary systems, we are helping utility providers achieve that same freedom. As a trusted European open source vendor, we deliver the hardware independence and transparent security grid operators need to fully own and audit their digital sovereignty – without being tied to a single legacy vendor.

What this means for the future

By integrating SUSE’s proven enterprise open source infrastructure with the collaborative power of LF Energy, we aim to accelerate the readiness of the SEAPATH reference architecture for production deployments.

The transition to a carbon-neutral world requires a smarter, more resilient grid. We are incredibly proud to join the SEAPATH community and work alongside utility operators, technology partners, and open-source developers to keep the lights on and drive the energy transition forward.
