Vancouver, BC-based Corinex Corp. and Plexigrid S.L., based in Stockholm, Sweden, have signed a strategic cooperation agreement to market Corinex Plexigrid Intelligence, a platform for low-voltage and medium-voltage power grids, built on what Corinex describes as accurate and granular power data.

Grid operators are facing the largest technological challenge in decades as demand for power-hungry AI applications increases, the electrification of industry, transport and heating/cooling accelerates, and the penetration of distributed energy resources explode. They must plan, operate and orchestrate in real-time a distributed, intermittent and bidirectional electricity system with millions of distributed energy resources (DERs). The next level of real time visibility, intelligence and control through their mid and low voltage sections of the grid is necessary to successfully solve this. The agreement is aimed at delivering that.

Corinex products are designed to observe and act on the physical grid, while Plexigrid software aims to model and optimize it. The partnership brings these complementary capabilities together, connecting real-time field intelligence with digital twin analysis, capacity decisions, and flexibility actions.

The integrated offering aims to help utilities see real-time voltage grid conditions, find available capacity, and act on network limits.

The new system was built around Corinex’s BPL architecture and edge-computing capabilities to place sensing, processing, and intelligence across the grid. This goal is to give Plexigrid’s digital twin richer and more accurate information from grid assets.

Transmission grids are modelled and operated in real time using redundant, high-resolution instrumentation at every node and an exact electrical topology, manually curated by a dedicated topology team. This creates the “observability” requirements that transmission control systems need to operate.

It would cost hundreds of billions of dollars and require hundreds of thousands of people to scale that approach from thousands of transmission nodes to tens of millions of distribution nodes, according to Corinex. This renders it unfeasible, which is why 99% of the nodes in the electricity grid remain unmodelled, according to the company.

Plexigrid delivers what Corinex characterizes as a more realistic answer to this problem: a digital twin equipped with a layer of Bayesian AI that reconstructs the electrical topology and the state of the grid from systems DSOs already have in place, such as GIS (used for field operations and asset management) and AMI (used for billing). This creates unprecedented visibility and control in parts of the grid that were previously unobserved or only partially observed, using data from systems that were never designed for real time grid observability and control. But while these Bayesian digital twins provide game changing capabilities and are fast and cheap to adopt at scale, they do not reach the time resolution and accuracy of transmission control systems.

Corinex’s BPL adds a layer of low-latency, high-resolution instrumentation and control that complements what DSOs already have across meters, feeders, transformers and other unmetered or partially observed grid assets, enhancing the performance and inference quality of these digital twins, the company said. The result is a level of time resolution, accuracy and real-time capabilities.

Additionally, Corinex’s Grid Intelligence Node installed on the low voltage lines expands the number of the measuring points and adds further detailed measurements from the physical network, the company said. This gives the twin a clearer view of loading, voltage, power quality, and emerging constraints.

“Utilities need more than connectivity and more than a cloud-based view of the network. They need an intelligence layer that can observe the physical grid, understand changing conditions, and support action at the speed required by modern distribution systems,” said Peter Sobotka, founder and CEO of Corinex Corp.

Corinex is built to deliver BPL, GIN, and edge capabilities across the grid. Plexigrid adds advanced digital twin and flexibility management capabilities with the goal of driving better capacity, investment, and operational decisions, Sobotka said.

“This partnership allows our models to be continuously grounded in high-resolution information from the physical network. Combining that information with distributed processing and advanced grid analytics creates a stronger foundation for planning, flexibility, and day-to-day operations.” said Alberto Méndez, CEO and co-founder of Plexigrid.
