How to simulate an energy hub in Wattix
An energy hub combines consumption, generation, storage and EV charging behind one grid connection. Whether it fits depends on how those assets affect each other every quarter hour. Wattix simulates them together, with one optimisation of the dispatch over the whole period, and shows whether import and export stay within the limits of the connection.
- What you put in
- The grid connection with its import and export limits, and behind it as many consumers, solar installations, batteries, charge points and generators as needed. Each asset gets its own profile or settings, from meter data, the Data Studio or the generation profile generator.
- What Wattix calculates
- Wattix works through the energy flows between all assets and the grid in 15-minute steps. Batteries and other controllable assets are dispatched in one optimisation at the lowest cost, within the limits of the connection. So you see the effect of the combination, not of each asset on its own.
- What comes out
- Import and export per quarter hour, the peaks, the number of days with an exceedance, the self-sufficiency and the total costs. By putting scenarios side by side, you see which combination of assets fits within the connection.

Frequently asked questions about energy hubs
Is the simulation suitable for energy hubs?
Yes, for a hub behind one grid connection: you combine consumption, solar, batteries, charge points and generators in one simulation. Several connections sharing a group transport agreement are, for now, simulated one connection at a time.
Solar panels, chargers and a battery: when do they work against each other?
When they need room on the connection at the same moment, for example when cars charge while the battery wants to charge too. Because Wattix works through all assets together every quarter hour, you see when that happens and which combination does fit within the connection.
What if the panels generate more than you are allowed to export?
Then the surplus has to go somewhere: into a battery, into consumption shifted to that moment, or it is curtailed. In Wattix you see how much energy exceeds the export limit and simulate what a battery or curtailing the panels does about it.
What does Wattix optimise the dispatch for?
The lowest cost within the limits of the connection, with the prices and tariffs of the contract you choose. The optimisation knows the whole profile in advance, so it gives the best achievable result. An EMS in practice doesn't know the future and rarely reaches that result in full.
