Insight into grid space, congestion risks, and flexibility options
Our Voltho load-flow simulations provide insights into expected grid capacity and congestion risks per location, based on assumptions. We help piece together the "grid puzzle": where congestion may arise, where there is still space, and how existing capacity can be utilized more intelligently. This clarifies what TDTR, VVTR, CSC, and CBC flexibility contracts can mean in practice. Which locations may be grid congestion-neutral or mitigating. And under what circumstances — high wind, high sun, or high demand — congestion can occur at your location. In short, we conduct location and situation-specific simulations for smarter use of the electricity grid.
Voltho Gridflow
Our Voltho Gridflow model includes stations, lines, transformers, impedances, power limits, and relevant loads/generation per node. We then simulate power flows for future years on an hourly or quarterly basis under different scenarios, such as high demand, lots of sun, lots of wind, or failure of grid components. We then analyze where lines, cables, or transformers become overloaded, which bottlenecks are critical, and how much flexibility or extra capacity is needed.
We provide transparent, highly validated, scenario-flexible, and high-quality grid congestion analyses.
Our vision
Our vision on grid congestion focuses on accelerating the energy transition through innovative solutions and collaborations. We don’t see grid congestion as a limitation but as an opportunity to use energy more intelligently by integrating technology, flexibility, and locally generated energy. Our goal is a future where growth and sustainability go hand in hand, despite the constraints of the electricity grid.
