Peak load
What is peak load? It is the situation when a high demand for electricity arises at the same time. Think of the evening hours when households are cooking, heat pumps are turning on and electric cars are being charged at the same time. The power grid then has to supply much more than average in a short period of time, leading to pressure and possible failures.

Energy storage system
An energy storage system (ESS) is a solution that allows you to temporarily store electricity for later use. This is particularly useful if you generate energy using solar panels or wind, because production and consumption often do not occur at the same time. Basically, it works like this: the system stores surplus electricity in a battery and returns that energy as soon as you consume more than you generate or when the grid is unfavorable (or expensive). This increases your flexibility, reduces your dependence on the electricity grid, and allows you to use energy more intelligently.

Frequency Containment Reserve
FCR today is a crucial factor in preventing outages and keeping power supplies stable. But what exactly is it? Imagine the power grid as a sophisticated orchestra in which every instrument - from huge wind farms to tiny solar panels - is perfectly tuned to each other. As soon as one instrument is in danger of going out of tune, there is a risk of imbalance. This is where Frequency Containment Reserve (FCR), also called primary reserve, comes in: an automatic system that corrects deviations in grid frequency at lightning speed. By adjusting or switching off energy within seconds, FCR ensures that our "concert" of generation and consumption remains pristine.
