          "European transmission system operators have achieved a critical milestone with the energization of the first multi-terminal 525 kV DC extruded subsea cable systems. Upgrading from conventional 320 kV links more than doubles transmission capacity per cable pair to 2,000 MW.",
          "These high-capacity HVDC corridors connect deep-water offshore wind clusters directly into high-inertia onshore nodes across the United Kingdom, Netherlands, and Germany, mitigating regional onshore bottleneck constraints."

          "The onshore and offshore converter platforms integrate advanced Modular Multilevel Converter (MMC) topologies equipped with grid-forming control algorithms. Rather than relying on physical synchronous generators for frequency reference, the converters actively synthesize voltage vectors.",
          "This ensures robust grid stability, synthetic inertia, and fault ride-through performance during severe AC grid disturbances."
