ROTTERDAM, 25 March 2025 – With the electricity grid nearing its limits, Rotterdam is accelerating collaboration and innovation to ensure key developments can continue.
Grid pressure prompts proactive city response
Following the December announcement that South Holland’s electricity grid has reached full capacity—Rotterdam included, with the exception of the Maasvlakte—the city has moved swiftly to address the impact on development.
Large consumers of electricity, such as schools, supermarkets and companies, are currently unable to obtain new or upgraded connections. However, existing contracts remain in place and are being optimised where possible.
Rather than allowing this to hinder growth, the municipality is working closely with grid operators TenneT and Stedin, as well as developers and business leaders, to minimise delays and find workable interim solutions.
Housing, schools and business still moving forward
The city has mapped out potential delays in housing and commercial projects. In 2025, eleven mixed-use developments could be impacted by temporary grid limitations. However, efforts are underway to keep these projects on track—particularly when it comes to essential services like lifts, ventilation and lighting in new apartment buildings.
Educational institutions and other public services also face delays, but are being prioritised where possible. A joint search for solutions—such as temporary setups and shared connections—is ongoing with Stedin.
The city is also supporting continuity in existing business areas and making strategic choices in the allocation of resources, enabling Rotterdam to remain attractive to new and existing enterprises.
Capacity expansion underway
Network expansions are already in development. TenneT expects additional capacity in Hoek van Holland, Rozenburg, Pernis and the port area between 2027 and 2029. For the wider city, new infrastructure is expected between 2032 and 2035.
In the meantime, Alderman Chantal Zeegers (Climate, Building and Housing) reaffirmed the city’s commitment: “Grid congestion is no excuse to pause. We are actively working with all partners to find what is still possible—through innovation, smarter planning and faster infrastructure development.”
Smart planning and energy innovation
The municipality is aligning grid upgrades with other infrastructure works to reduce delays. Discussions with Stedin are exploring how critical services—such as lifts in housing blocks—can be prioritised even within current limitations.
A range of innovations is being promoted. The city is co-financing so-called Flex Scans, which help companies use their existing electricity connections more efficiently. Up to 80% of costs are reimbursed, encouraging broader participation.
Through the Smart Energy Systems subsidy programme, entrepreneurs are also being encouraged to develop tailored solutions. Examples include energy-sharing hubs in Schiebroek and improved energy efficiency in the port area.
Supporting businesses and developments
The city is inviting companies and developers to explore creative approaches within their existing grid contracts—such as energy sharing, local storage and flexible use.
Advice, subsidies and practical support are available through the municipality, and early conversations with Stedin are strongly encouraged.
All current measures and future plans are outlined in the “Rotterdamse Aanpak Netcongestie” (Rotterdam Net Congestion Approach), which is updated every two years to reflect the latest developments.
