In an exclusive interview with Energía Estratégica España, Abhikalpa Ghosh, Senior Associate at DSK Legal, analysed the recent decision by the Dutch government to exclude offshore floating solar panels (OFSPs) from upcoming offshore wind farm tenders. According to Ghosh, this move is «cautious rather than restrictive» and seeks to protect the country’s already congested electricity grid.
Grid congestion, a critical issue in the Dutch energy sector, was the primary factor behind this decision. «The current system faces significant challenges due to limited grid capacity, especially in rural areas where demand exceeds transmission capabilities,» Ghosh explains. Urban areas also face shortages caused by high population density and increasing energy demands, further complicating the situation.
The impact of this decision should not be seen as a rejection of OFSPs but rather as a strategic pause. «The development of OFSPs has not been abandoned; instead, the focus is on optimising the grid before introducing new complexities,» the expert highlights. The government is taking measures to manage congestion, including the development of energy storage systems and allowing flexible transmission rights. These initiatives are crucial to avoid system overloads while working on long-term solutions.
Technological Challenges and Opportunities for OFSPs
Floating solar panels, although promising, face significant technological barriers. These include high upfront costs, the durability of materials in marine environments, and integration with existing technologies. According to Ghosh, innovation in corrosion-resistant materials and advanced anchoring systems could accelerate their development. «Progress in these areas will be key to establishing OFSPs as a viable solution in the future energy landscape,» he notes.
A recent example of success is the award of the 50 MW OFSPs project led by Vattenfall and Copenhagen Infrastructure Partners, considered a milestone in the sector. However, the government’s decision could influence investors’ perceptions of regulatory stability. Nevertheless, Ghosh emphasises that «the current approach sends a clear signal: the government prioritises long-term sustainability over immediate solutions that might exacerbate existing problems.»
Sectoral Impact and Future Outlook
The exclusion of OFSPs may not deterr major developers, who havediverse investments across wind, solar, and other renewable projects. This strategy not only mitigates risks but also ensures steady sector growth. Additionally, state-owned grid operator TenneT is leading efforts to alleviate grid congestion, with significant investments to accommodate more renewable projects in the near future.
The role of OFSPs remains vital to the Netherlands’ carbon neutrality goals by 2050. This technology could complement offshore wind farms, maximising the use of maritime space. Ghosh suggests that «once current limitations are resolved, the government is likely to reconsider its position on OFSPs,» particularly as technological advancements and grid expansions make their integration more feasible.
Governmental Measures Underway
To address grid congestion, the government has implemented several practical measures. These include agreements to restrict capacity during peak hours and prioritising connections for essential services. Furthermore, the mandate for installations with over 60 MW capacity to contract flexibility adjustments with operators could prove crucial in easing grid pressure.
Another solution in development involves large-scale battery storage systems to retain surplus energy during low-demand periods. According to industry experts, these initiatives could significantly reduce transmission issues and pave the way for a broader integration of OFSPs.
