Why is automation essential for block power?

Block Power works well only if you know exactly when the block hours start and end, and if you can automatically adjust your consumption. Manual control is virtually impossible: peaks arise quickly, and grid operators measure every fifteen minutes or every minute. Even a small overshoot can lead to fines or penalties.

A smart EMS takes care of this. It monitors current consumption, compares it with the block hours, and intervenes automatically when the limit is approached. This ensures your company always stays within agreements, without unnecessarily disrupting production or charging processes.

What exactly does a smart EMS do for block power?

A modern EMS combines real-time data processing, control, and forecasting. In practice, this means:

1. Monitoring: continuous measurement of consumption, generation, and available power per phase or connection.
2. Calendar Logic: automatic recognition of block hours based on the grid operator's schedule.
3. Smart Control: temporarily switching off consumers or charging points outside block hours, without production loss.
4. Forecasting: analyzing usage patterns to spread consumption across available blocks.
5. Reporting: insight into compliance and utilization rate of block hours for audits or optimization.

In this way, the EMS acts as a 'digital traffic controller' for your energy flows. The software continuously determines what is and isn't possible within the transport rights.

What does that look like in practice?

Consider a logistics center with 20 charging stations and a limited grid connection. The grid operator offers a block power contract entitling them to 800 kW between 10:00 PM and 06:00 AM. During the day, a limit of 200 kW applies. Without management, the center would easily exceed this limit during the day. With a smart EMS, the following happens:

• Beforehand: the EMS schedules charging sessions so that heavy peaks occur at night.
• During the day: only vehicles that urgently need to depart charge with limited power.
• Automatic switching: as soon as the block hour starts, the system automatically increases the charging speed.
• After the block: remaining charging tasks are paused or shifted to the next block.

The result: 100% compliance with the block power contract, without manual intervention or production loss.

What data does an EMS use to manage?

To intelligently plan consumption, an EMS combines multiple data sources:

• Measurement data from the connection: current load and power peaks.
• Weather forecasts: impact on PV generation or cooling loads.
• Production Planning: operational schedules linked to energy demand.
• Price Information: connection with dynamic tariffs or imbalance markets.

By combining this data, the system knows not only what is happening now, but also what will be needed in the future. This makes planning predictable and compliance simple.

What does this offer businesses?

Implementing an EMS for block power offers three direct benefits:

1. Stress-free Compliance: automatic monitoring prevents overruns and penalties.
2. Higher Utilization Rate: the system optimally uses block hours, without wasting energy.
3. Financial Advantage: lower grid costs through efficient use, plus retention of operational flexibility.

According to RVO companies that actively manage with EMS systems can do up to 25% more within the same grid connection — precisely what block power aims for.

Integration with battery storage and charging infrastructure

One of the strongest combinations is that of block power with local storage. Batteries can store energy during block hours and use it later when grid interaction is restricted. This keeps production stable, even outside the agreed windows.

• Charge management: the EMS determines when charging points are active and how much power they can use.
• Battery management: store energy during block hours and discharge outside the blocks.
• Production priority: the EMS distributes power between machines, lighting, and HVAC based on priority.

This creates a fully automated energy management system: the right processes run at the right time, without human intervention.

What are the next steps for businesses?

Anyone considering a block power contract should first analyze the flexibility of their consumption. Ask questions such as:

• Which processes can we shift to night or weekend blocks?
• Do we have assets (such as batteries or EV charging points) that are flexible?
• Can we measure in real-time and control automatically?

Based on that analysis, a smart EMS can be set up to plan consumption within the block hours. This is often feasible within a few weeks, without major investments.

How can I apply for block power?

You can request block power through your grid operator. On blokstroom.nl , you'll find a guide per grid operator on how to apply for block power.

Conclusion: Block power only works with smart control

Block power is a powerful tool to enable growth on a congested grid, but only if managed properly. Manual planning is not sustainable; automation is essential. With a smart EMS , you utilize each block optimally, prevent overruns, and reduce costs. This way, block power transforms from a limitation into an opportunity to operate smarter, more flexibly, and future-proof.
