With Companion.energy
Proximus is developing the Proximus Energy Box in collaboration with Companion.energy, an innovative software that will help us integrate real-time and forecast data from assets, energy contracts and the energy market to optimize renewable energy usage and costs.
Most common energy challenges.
We give telecom operators a smarter, integrated way to manage their energy context within 6 months.
Centralize energy cost data across all sites, meters, and contracts
Monitor day-ahead profile (risks) to contract better and optimize asset steering
Track your energy prices in real-time, in both absolute and marginal terms
Match renewable energy to actual consumption, 15-min by 15-min
Forecast energy consumption to nominate in the day-ahead market and control imbalance
The future is calling
7 ways to cut costs, reduce risk, and turn energy into a growth lever with real examples from leading telecoms.
- How to reduce exposure to price swings
- Ways to use flexible backup batteries, EVs, and cooling to generate value
- How TelCo’s are managing 24/7 renewable matching
- Examples of new service bundles

Your infrastructure is complex.
Your energy tools shouldn’t be. You already have the network. We’ll help you run it smarter—one step at a time.

Frequently asked questions
Companion.energy complements your consultant’s work. While consultants focus on long-term, discrete optimizations, we handle the "minute-by-minute" reality. Our software enables continuous (re-)forecasting and real-time optimization to maximize the impact of those decisions.
What really matters is how your additional or reduced grid consumption is priced. In practice, over 90% of large companies are marginally exposed to day-ahead and/or imbalance prices.
Flexibility comes in many forms, and we often help uncover hidden potential with our customers. Let’s explore it together.
If you manage energy, energy costs and emissions, work in GWh, and measure energy expenses in millions — Companion.energy is for you!
