Flexible steering, maximum value from your renewable energy assets for the next 20 years
Renewable energy assets do not generate their maximum value on their own. After engineering, permitting, development, financing, installation and commissioning, what follows is equally demanding, and equally decisive: active steering, at every moment of the day.
Grid tariffs are up 39%. Negative price hours hit 518 in Belgium. The revenue stack is shifting.
Grid tariffs are rising. In Flanders, distribution network tariffs for medium-voltage users increased by an average of 39% in 2025 (source: VREG, December 2024). With over 518 hours of negative electricity prices recorded in Belgium in 2025 (source: Gridio), new opportunities are emerging for companies that load, dispatch and steer at the right moment. The value lies in the combination of day-ahead optimisation, peak shaving and maximum self-consumption, and that combination requires continuous, active steering based on real-time market signals.
Belgium is not an outlier. The same dynamics, rising network costs, growing renewable surpluses and structural price volatility, are reshaping energy markets across Europe.
PerPetum builds and operates. Companion Energy optimises. Together, we steer.
As Mathieu Tahon, Chief Investment Officer at PerPetum, puts it:
"We've moved beyond renewables as a commodity. It's no longer just about the PPA. It's about creating value through flexibility, steering and adaptability."
PerPetum brings the engineering, project execution and long-term operational knowledge. We develop, build and operate large-scale on-site energy systems, from permitting and financing to daily optimisation, so our clients can systematically lower their total cost of energy.
Companion Energy brings the software intelligence: an optimisation platform that combines production and consumption data with real-time market signals and continuously takes the best dispatch decisions across all available value streams.
Together, we actively steer a portfolio of over 200 MWp in Belgium and are expanding across the Netherlands and the rest of Europe, with one shared objective: to systematically lower energy costs and strengthen the competitiveness of our clients.
Cut costs, valorise surpluses, reduce grid exposure and see every euro of value in real time.
-
Cut your total energy cost through day-ahead optimisation, peak shaving and maximum self-consumption.
-
Valorise electricity surpluses and reduce fossil thermal demand by converting electricity into heat via e-boilers or heat pumps, not only when prices are negative, but whenever electricity is cheaper than gas, or into EV charging, rather than injecting at a loss or continuing to rely on fossil fuels.
-
Reduce your carbon footprint by electrifying heat and mobility processes with on-site renewable generation, directly replacing fossil fuel consumption.
-
Reduce your exposure to grid congestion by actively managing flexible loads within your connection capacity.
-
See exactly how value is created, in real time, through a transparent and intuitive dashboard.
All of this without upfront investment, structured as a PPA (Power Purchase Agreement) or Energy-as-a-Service.
The market will keep evolving. This partnership guarantees our clients that their assets deliver maximum value, today and across a 20-year horizon.
