Market-indexed contract: how to turn Belpex volatility into a savings lever
Electricity prices on the Belgian market can no longer be managed as they were ten years ago. The rise of renewable energy has reshaped the price curve across seasons, and spring 2026 is yet another illustration of this.
The new price structure
Over the past 60 days, the average day-ahead price settled at around €85/MWh. But behind this average lies a more nuanced reality: solar hours, from mid-morning to early afternoon, consistently show the lowest prices of the day. At night, by contrast, the market remains dependent on thermal power plants and therefore subject to higher prices.
This is the inversion we have been anticipating for several years: noon has become the cheapest hour, when solar production is at its peak. For companies on a Belpex-indexed contract, this structure creates a direct lever.
What smart control enables in practice
During this period, prices were zero or negative for nearly 9% of the time. For a company with flexible consumption (industrial refrigeration, compressed air, electric vehicle charging), these windows represent as many opportunities to reduce the energy bill without any impact on production.
An EMS connected to real-time Belpex prices automatically shifts these loads to the cheapest hours. On a flexible load of 100 kW, monthly savings can reach several thousand euros, simply by consuming at the right time.
For PV producers, the logic is complementary: rather than injecting onto the grid during low-price hours, a managed battery stores this energy and valorises it later. The result is a direct improvement in the return on investment of the solar installation.
Our approach
We analyse your consumption profile against real market data and quantify what an EMS-driven control strategy would have saved over the past 60 days.
