About the company:
⚡ envelio - Supporting the smarter, faster evolution of your power grid.
We provide distribution grid operators with the Intelligent Grid Platform (IGP) – a software suite that brings all your grid data together to enable real-time decisions, long-term planning, and much, much more.
With real-time digital twins, automated grid assessments, and live monitoring, IGP empowers DSOs to manage increasing infrastructure complexity, renewable integration, and growing power demand.
Our applications cover the full spectrum of operations and planning:
🔹 Process thousands of connection requests in minutes, not days
🔹 Detect grid congestion risks before they cause trouble
🔹 Simulate and plan new grid areas with confidence
🔹 Evaluate the grid impact of EVs, PVs, and heat pumps before they’re built
IGP integrates seamlessly with existing systems like GIS, NIS, SCADA, MDM, EDM and others – enhancing visibility without overhauling existing workflows. And because it’s modular, grid operators can start where they need impact the most.
Trusted by grid operators across Europe and beyond – from Westnetz to Helen Electricity Network and Eversource – envelio's IGP is setting new standards in grid management and planning, facilitating a smoother transition to renewable energies.
💡 Not sure which part of IGP fits your needs? We’ll help you find it.
