Proximus optimizes energy use with smart Energy Box

Proximus is taking an important step in the energy transition by using the Energy Box, an innovative application that helps manage buildings more energy-efficiently. In May 2025, Proximus has deployed this technology across 44 Proximus buildings and mobile base stations to better manage energy consumption and increase the use of renewable energy.

The Energy Box was developed in collaboration with Companion.energy, a Belgian startup that supports companies in optimizing their energy use. They do this through advanced data analysis, real-time market insights, and artificial intelligence. This includes a so-called digital twin, a virtual copy of the energy system that continuously collects and analyzes data from all locations.

As part of its ambition to become climate neutral across its entire value chain by 2040, Proximus is committed to sustainable innovation. The Energy Box helps reduce energy consumption in buildings and mobile sites and maximizes the use of renewable sources such as solar and wind energy, even when these are not constantly available.

Smart, data-driven energy control

The Energy Box analyzes real-time energy use alongside market prices, contract conditions, and in-house energy generation, such as solar panels. Based on this data, the system sends out intelligent control signals, determining the best times to ramp up or pause certain installations, such as cooling systems and batteries. This allows Proximus to respond flexibly to the availability of renewable energy while keeping costs under control.

From pilot to rollout

Following a successful test phase in 2024, Proximus began rolling out the Energy Box at 44 locations in May 2025. In the next phase, the solution will be extended to additional sites. This project enables Proximus to manage the energy consumption of its buildings more intelligently, sustainable, and cost-effectively.
