Commercial and Industrial Energy Consumers: The Case for Going Dynamic

Dynamic energy tariffs did not begin with households and EV owners. They began with industry. Large industrial consumers have had access to some form of market-linked pricing for decades — it was simply not available at smaller scales. As technology has made granular metering and market access economically viable at lower consumption thresholds, the same logic that made dynamic pricing compelling for a steel mill now applies to a logistics warehouse, a data centre, a supermarket chain, or a mid-sized manufacturing operation.

The Scale Effect

The financial case for a dynamic tariff is directly proportional to consumption volume. A household saving €300 a year through smart scheduling is pleased. A mid-sized business consuming 500,000 kWh annually and saving even €15 per MWh through strategic load management is saving €7,500 per year. A large facility consuming several GWh annually with meaningful operational flexibility — the kind of flexibility that can be engineered into shift scheduling, equipment sequencing, or auxiliary system timing — is looking at potential savings of tens of thousands of euros.

At commercial and industrial scale, the business case for proper energy management is not marginal. It is a material P&L line.

Where Flexibility Exists in Commercial Operations

Businesses are often surprised by how much operational flexibility they actually have once they map their consumption against the question 'does this actually need to happen right now, or just today?' Cold storage facilities can adjust temperature setpoints within safe ranges, creating thermal storage. Compressed air systems can run charge cycles during cheap periods and coast during expensive ones. EV fleet charging can be entirely scheduled. HVAC pre-conditioning can shift peak demand. Batch manufacturing processes can be sequenced against the price curve.

Not every load is flexible. But in most commercial operations, a meaningful portion of consumption is — it just requires someone to ask the question and build the logic around it.

The Data Advantage

Businesses on dynamic tariffs develop a much more granular understanding of their energy costs than those on flat-rate contracts. You can see exactly what each piece of equipment is costing you, at what time, and against what price. This visibility has value beyond the tariff itself — it informs equipment upgrade decisions, operational scheduling, and capital investment in efficiency measures.

Procurement Strategy for Larger Consumers

For businesses consuming at scale, dynamic tariffs can also be structured as a component of a broader energy procurement strategy — combining spot exposure for flexible loads with longer-term contracts (Power Purchase Agreements or hedged supply contracts) for baseload, inflexible consumption. This portfolio approach optimises risk and cost simultaneously. 10s Energy works directly with commercial customers to design the right structure for their specific consumption profile and risk appetite.

Capacity tariff Flanders

Since January 2023, part of your grid cost is based on your peak 15-minute draw each month — not just total consumption. The higher your simultaneous load, the higher your capacity tariff.

Neither the standard dynamic nor the 10s Smart costs include the supplier's commercial margin. The fixed market reference already embeds a typical margin — the dynamic figures do not.

Belgian dynamic tariff providers typically charge €0.015–0.025/kWh above spot plus an annual fee of approximately €50–80/yr (Luminus: €0.021/kWh + €75/yr; Engie: spot × coefficient + fixed constant).
