Understanding the effect of Grid Congestion on Construction Sites
Grid congestion occurs when energy demand exceeds the available network capacity at specific locations and times. As a result of this, new connections are often postponed or only available for lower transport capacities.
Construction projects, especially those shifting towards electric machinery, often see spikes in electricity consumption. This can happen when a tower crane has to lift a heavy load or when multiple electric vehicles are in charging sessions at the same time.
In the past, this peak in energy use would not be a huge issue. By requesting a high capacity grid connection, the available transport capacity would be enough to manage the peak. Nowadays, chances are that you cannot start your construction because of the long waiting times for high capacity connections. Instead, construction companies are forced to make due with lower capacity connections.
This introduces a risk. This lower capacity is most likely fine for the base load of the project but it could give some issues during peaks. This can result in operational disruptions, costly delays, or even fines from energy providers.
Practical Solutions to Address Grid Congestion
- Advanced Energy Forecasting: Utilize predictive software tools that accurately simulate your construction site’s energy demand throughout each phase of your project. Forecasting tools can help you anticipate peak load periods, enabling more effective planning. For example, if you expect a peak at the end of the day because of the expected charging demand, you can change your charge planning or look for external charging locations.
- Energy Storage Systems: Deploy battery storage solutions to balance energy consumption. Storing electricity during low-demand periods to use at peak times can significantly alleviate grid pressure. Batteries also provide backup power, enhancing resilience and reducing downtime risks.
- Dynamic Load Management: Smart management of electric machinery can distribute energy use more evenly across the day. Prioritize high-energy activities outside peak grid times, utilizing energy management software to automate and optimize equipment usage schedules.
- On-Site Renewable Generation: Integrate renewable energy sources, such as solar panels or temporary wind solutions, to produce your own electricity. This reduces dependency on the grid and provides greater flexibility, especially in grid-congested areas.
- Collaboration with Network Operators: Establish early and proactive communication with grid operators. Clear dialogue helps align your project’s energy requirements with available network capacity, allowing for joint planning of temporary grid enhancements if needed.
Preparing for the Future
As electrification accelerates, proactive management of grid congestion will become essential. By embracing practical solutions like advanced forecasting, energy storage, and smart equipment scheduling, program managers can ensure projects run smoothly and sustainably, maintaining a competitive edge in the zero-emission construction landscape.
Even if you are not really facing congestion issues with project yet, if you are planning to move towards more electric equipment it’s beneficial to start with collecting data. This way, when you encounter a project with energy capacity restrictions, you have the insights to understand the impact.
