The balance of the electricity networks: at the heart of the issues

The quantity of electricity injected (produced and/or imported) and the quantity of electricity consumed on an electricity grid must always be equal. If the balance is not found, two situations are possible:


Large electrical frequency fluctuations


Blackout or uncontrolled load shedding


Today, intermittent renewable production, in other words, the production of natural flows that are not permanently accessible and whose availability varies greatly without being controllable (wind and sun, to name but a few examples), is constantly increasing.

The unpredictability linked to the nature of these energies can thus cause imbalances that can have significant repercussions: variation in the costs of producing these energies, harmful to the stability of the networks.

As a result, network operators have an increasing need for services to balance their networks.
