ROTTERDAM, 20 January 2025 – An innovative approach to emission-free construction is underway in Hoek van Holland. Electricity from the Rotterdam metro network is powering equipment at the site, marking a significant step in sustainable building practices.
Ret electricity fuels sustainable construction
Mobile machinery on the former military campsite, now being transformed into a nature reserve, is operating using electricity supplied by RET's overhead metro lines. The RET, which received a permit last year to supply electricity to external parties, is utilising surplus capacity to charge an electric excavator at the site. This project is the first in the Netherlands to use RET's electricity in this way, enabling emissions-free construction without the use of traditional fossil fuels.
Linda Boot, director of RET, commented, “The RET is the first public transport company in the Netherlands, and likely in Europe, to receive a permit to supply electricity to others. Our metro and tram vehicles do not always utilise all available capacity, which allows us to use the network more efficiently. The connection in Hoek van Holland is a prime example. Our overhead network is essentially Rotterdam’s longest extension cord, providing many opportunities to alleviate grid congestion.”
A step towards emissions-free working
The municipality of Rotterdam commissioned the redevelopment of the 3-hectare site, which had previously served as a camping area for military families. Since 2021, the land has been managed by Stichting Het Zuid-Hollands Landschap. The redevelopment aims to increase green space and biodiversity while aligning with the city’s goals for clean air and reduced CO2 emissions.
Alderman Zeegers (Climate, Building, and Housing) stated, “We worked on an innovative solution to minimise emissions during the redevelopment of the Vafamilterrein (former military site). Rotterdam supports such initiatives, particularly as they gain importance in light of network congestion. Our aim is a healthy city with clean air, where growth goes hand-in-hand with environmental improvement.”
Protecting ecosystems with green building
This project represents the first experience with electric equipment for Het Zuid-Hollands Landschap. Director Jos Bisschops noted, “In areas bordering Natura 2000 sites, emissions-free working is critical to protect fragile ecosystems and reduce nitrogen emissions. This pilot project is an important step towards making emissions-free construction the standard.”
Future opportunities for sustainable energy use
The RET and the municipality of Rotterdam are planning further collaborations. As network congestion limits new electricity connections, the RET’s network offers an alternative for projects that would otherwise face delays. The RET’s permit also supports the development of charging infrastructure for vehicles and equipment, contributing to the city’s ambitions for emissions-free mobility and construction.
