Those units consist of different technologies, with CHPs being the most prominent. Leading up to the successful implementation of the Belgian aFRR pool’s operations, Next Kraftwerke went through the prequalification process of the Belgian transmission system operator Elia, to proof the ability of the networked units to deliver aFRR to the grid. When delivering aFRR reserve power, it is imperative to follow the TSO’s setpoint for the activation accurately. When one unit responds in a different way than expected, the Virtual Power Plant automatically compensates by adapting the setpoint for other units in the fleet. This way, the entire pool can deliver this crucial balancing product with higher accuracy than conventional large-scale power plants.
Next Kraftwerke is prequalifying more assets on an ongoing basis, to grow the the Belgian aFRR fleet further.
