Self-consumption

Self-consumption (or on-site electricity consumption) refers to the share of generated electrical energy that is consumed directly at the place of generation - such as in a business or household - without being fed into the public distribution grid.

How does self-consumption work?

A typical example is a photovoltaic system that generates electricity during the day. If this electricity is immediately used for lighting, production, or running appliances, it is considered self-consumption. On the other hand, if the electricity is not consumed at the moment of generation, the excess energy can either:

be fed into the grid (in systems without a battery),
or stored in a battery storage system and used later - which increases the self-consumption rate.

Why is self-consumption important?

It reduces electricity costs - less energy needs to be purchased from the grid.
It increases the return on investment in photovoltaics and smart battery storage.
It reduces the load on the distribution grid and lowers grid-related fees.
It increases energy self-sufficiency and security.

How to maximize self-consumption?

The highest efficiency is achieved by combining:

photovoltaic systems,
smart battery storage,
and an intelligent Energy Management System (EMS), which optimizes electricity usage in real time based on production, consumption, electricity prices, and available flexibility.
