LF Energy members have collaborated to create a concept of a high-level architecture for the power grid of the future. The architecture starts with a top-level view and progresses to a finer granularity showing areas of focus. The final image shows how each of the existing – and some future – LF Energy projects fits into this architecture.

Our Commitment to the Future Digital Grid

To achieve our 2050 climate and energy goals we, as TSOs and DSOs, have joined together to create a common high-level architecture defining a fit-for-the-future grid. What follows is a start. We want your feedback and involvement. With this we proclaim a commitment under LF Energy to find shared strategic dependencies. By utilizing open source we can accelerate a technology revolution that enables rapid decarbonization by digitalizing the global energy grid.

We see that cooperation and working together is the only path to individual and collective success. Join us.
