HVDC Classic

Time-tested and future-proof

Energy systems around the world are becoming increasingly decarbonized, distributed – and demanding. That’s why HVDC Classic steps into the limelight: It provides transmission system operators with an exceptionally economical and efficient opportunity to supply load centers. Such a bulk power transmission system delivers the required amounts of power, stabilizes heavily strained AC grids, and establishes an interconnected power system across regions and countries. The proven technology behind HVDC Classic, which is based on line-commutated current-sourced converters (LCC), has been continuously improved over the years. Today, HVDC Classic systems from Siemens Energy transmit up to 12 GW of power, this way providing the secure, stable, and profitable backbone for today’s increasingly complex transmission systems as well as for grid interconnection and for UHVDC transmission.

High-performance power highways with HVDC Classic

Today, many transmission system operators are required to provide additional grid capacity and improve grid performance and resilience. They’re also expected to take an active part in the establishment of interconnected power systems and contribute to CO2 emissions reduction through the integration of power from renewable sources. HVDC Classic provides the opportunity to tackle these challenges successfully.

Efficient bulk power transmission

Growing power demand and the worldwide push for the decarbonization of energy systems call for new approaches in power transmission. The challenge is to establish bulk power transmission systems to get power from lucrative but far off renewable energy sources right to the load centers. UHVDC transmission technology from Siemens Energy provides the efficient, reliable solution.
