Dual-use solar in the Netherlands and the connection queue

The case for dual-use solar in the Netherlands is usually made on land. A post by The Energy Shift lists rooftops, solar carports, greenhouses and floating solar as ways to generate electricity in spaces that already serve a purpose, and concludes that the future of the technology depends as much on where it is installed as on how much it produces. That framing is the author's thesis; the regulatory picture here comes from an independent source.

In the Netherlands, what separates these projects today is the grid queue. The ACM's Codebesluit prioriteringsruimte transportverzoeken 2025 amends the Netcode Elektriciteit and, since Jan. 1, 2026, obliges grid operators to apply a prioritisation framework in congestion areas. Three categories may be granted preference in the allocation of capacity, and the first is congestion reducers.

That changes the investor's arithmetic. Where capacity is scarce, a finished asset earns nothing until it is connected. Rooftops, carports and greenhouses tend to sit behind an existing connection, with consumption on site, and depend less on new transport capacity. Floating solar, typically an exporter, depends on it.

Siting has become a financial variable, not only an environmental one. On a congested grid, the project that reduces demand for new transport shortens the interval to first revenue.
