Possible solutions for grid congestion
Is your business suffering from grid congestion? For example, can your business premises not connect to the electricity grid? Or can you not deliver energy you generated back to the grid? Check out the possibilities to reach a solution.
Grid congestion, insufficient capacity on the electricity grid, occurs because we generate a lot of electricity at one moment and consume a lot at the next. The following solutions are already in use and show good results in grid congestion areas.
With energy management you adjust the energy consumption of your appliances at the moment you use them. You do this with an energy management system (EMS). For example, charging your charging stations when there is a lot of solar energy available. The system can also temporarily switch off processes that use a lot of energy. This reduces peak demand on the grid.
EMS software gives insight into the energy flows and the costs of your building. With that knowledge you can coordinate your energy better. This will help save energy and costs.

When you generate electricity, you can store surplus electricity in a battery energy storage system (BESS). You can then use it at a later moment. This applies especially to generated electricity from your own solar panels or wind turbines.
Make an overview of your energy consumption and generation. Then see how to use your energy supply in a smarter way. And how a battery can contribute. When buying a battery, you can make use of the Energy Investment Allowance (EIA). Then you can offset 40% of your investments against your personal or corporate income tax.

Electricity conversion involves converting surplus electricity, for example from wind turbines and solar panels, to other forms of energy, such as heat or hydrogen. This makes your business less dependent on the electricity grid.
You do need to have enough room to convert electricity into heat or hydrogen. And you or buildings nearby must be able to use this converted energy. Check with your municipality whether a permit is required for electricity conversion. This depends on the location and size of the electricity conversion, but also on the consequences for the environment.

With a capacity limiting contract, you flexibly adjust your electricity consumption or delivery based on the available capacity on the grid. Your energy provider will financially compensate you to reduce your energy consumption when demand is at a peak. Or if you agree on the moments when you can deliver energy to the grid.
You can conclude a capacity limiting contract on your own or together with other entrepreneurs through the network operator. There are various contract forms for consuming and for delivering energy.

With so called cable pooling, different energy sources share one grid connection. This usually involves at least 2 sources that produce electricity, such as solar panels and wind turbines.
These energy sources may have different owners. For example, a neighbouring company sets up solar panels near your wind turbine. You can then agree they connect their cable to your grid connection. This way, you make better use of the available grid capacity when it is sunny or windy. Sharing a single cable also avoids extra connection costs and double grid management charges.

With a direct line, you supply your generated electricity directly to a large user in your neighbourhood. For example, a business that consumes a lot of energy. You do not use the general electricity grid. So, this customer uses your generated electricity directly. Do make sure that the energy consumption of that neighbour matches your generation profile (similar and simultaneous consumption).
The local infrastructure must make it possible to set up a direct line. If you have to run your cable under a river or a busy road, for example, it is sometimes not possible to have a direct line. Ask your municipality whether a direct line requires a permit. This depends on the location and size of the direct line, but also on the consequences for the environment.

Within an energy hub, a group of businesses have a group contract with the grid operator. As a group, you then manage the generation and consumption of energy yourself. This way, you make better use of the available capacity together: supply and demand are better matched.
This allows you to coordinate energy generation, transportation, storage, conversion and consumption.
Energy hubs come in different sizes, often develop in stages, and can add new activities at a later stage. Consider, for example, investing in generation facilities or storage. In order to be able to work and invest together, the participants in an energy hub make agreements with each other.
Network operators are working hard to develop this group contract. This option will become more available in the coming years. Check the expected availability on NetbeheerNederland (in Dutch) and ACM (in Dutch).

Not only for large companies
Some of the solutions in this article are only suitable for larger users. But there may be possibilities for you to collaborate with other companies in your vicinity to deal with grid congestion. By working together, smaller businesses have an opportunity to join in the plans of, and work together with larger companies nearby. Are you a member of a business park association? Then perhaps you can come up with a grid congestion plan together.
