In the rapidly evolving energy landscape, Prysmian, a global leader in energy and telecommunications cable systems, marks a turning point with an innovation that promises to accelerate the energy transition and reduce costs for consumers. The key to success lies in a new advanced plastic insulation, capable of operating at temperatures up to 90 degrees Celsius, allowing submarine cables to reach unprecedented power levels.
More Power, Lower Costs: The Submarine Cable Revolution
The upgrade of Prysmian's 525 kV HVDC (High Voltage Direct Current) submarine cables is not a simple improvement, but a true revolution. The increase in transmission capacity from 2 to 2.5 GW per single link means enough energy to power approximately 500,000 additional homes. Compatibility with existing infrastructure is another strong point, as the power increase does not require modifications to offshore platforms or converters, slashing adaptation costs for grid operators.
Prysmian has already completed testing and is preparing for the commercial launch of this new global standard. The company, bolstered by a fleet of eight cable-laying ships by 2028, further consolidates its leadership position in the sector. The growing demand for cables, with production capacity doubled to 4,000 kilometers per year, and investments, such as the 450 million euros from the European Investment Bank, demonstrate confidence in the future of this technology.
Key Projects and Global Impact
The most immediate applications concern multi-terminal networks and next-generation hybrid interconnections, which combine long-distance power transmission with offshore wind production. Projects in the Netherlands, the United States, and Great Britain demonstrate Prysmian's commitment to supporting the energy transition. Optimizing the economic efficiency of these projects, by lowering the unit cost of transmitted energy, promises to reduce costs for end consumers.
The European energy transition requires infrastructure that increases capacity while reducing costs. Prysmian's innovation meets this need, offering more power, maintaining the same infrastructure, and reducing operational costs. This solution, compatible with existing infrastructure, has the potential for a global impact, accelerating the transition towards a more sustainable and efficient energy future.
