Grid operator support
Connection and communication supportGrid congestion is local. And continuously changing.
Capacity maps, historical congestion data, availability profiles, and national scenarios provide insufficient insight for location- and scenario-specific project decisions. We offer suitable location and congestion insights based on our continuously updated Voltho databases of grid expansions, battery projects, e-boilers, wind farms, solar panels, and users.
Gridflow in action
How many MW can I still connect?
Electrification of industrial location
For an industrial client, we determined the additional electrical capacity required and optimized behind-the-meter flexibility options. This allowed us to assess how electrification could fit within the available grid capacity, resulting in a more efficient and effective grid operator process.
What does the flex contract mean?
Non-firm flexible contract impact analysis battery park developer
For a 200 MW / 800 MWh battery project, we simulate hour by hour when a Dutch TDTR restrictions may occur and how much capacity remains available. This quantifies the impact on uptime and the business case.
Where to develop optimally on the grid?
Grid location optimization GDS & battery park
For a developer of Closed Distribution Systems and solar and battery parks, we compared potential locations based on grid load, congestion risk, and future grid expansions. Multiple locations were compared to select the most optimal grid situation.
One Voltho Gridflow model. Four decisions that rely on it.

How Voltho Gridflow works
Grid modelling
Existing and future electricity grid
Dispatch simulation
Hourly profiles by sector and location for generation, demand and flexibility..
Grid load-flow and congestion analysis
Load flow and N−1 analysis identify where and why congestion occurs.
Translation to project decisions
Impact on location, contract, policy and business case
What we deliver
Hourly data in Excel and a clear PDF management report.
☑ Where and when does congestion occur?
Hourly simulations of future grid load and available capacity.
☑ What does this mean for you?
Translation to your project, location, area, portfolio, or policy.
☑ What causes it — and what changes?
Insight into the impact of demand, generation, storage, and grid expansions.
One model. Threefold validated.
Reliability is based on three separate checks
Model methodology
We use the latest technology to perform dispatch and load flow simulations.
Input data
This is where Voltho makes a difference. We can work with the grid operator's assumptions or with our most recent data and forecasts.
Outcome
We historically validate against independent public market data — the most convincing form of validation.
Why choose Voltho
Grid physics and your project
We translate grid constraints into impact on your project, location, or policy and vice versa.
Independent Grid Intelligence
Independent grid simulations based on your or our own market data.
Own grid models and market data synergy
Our market data and grid models continuously reinforce each other.
From grid engineer to market strategy
Grid engineering, energy storage, and energy strategy combined.
