PURPOSE AND SCOPE

Many of the technologies required for strategic optioneering are new and developing rapidly. Voltage Sourced Converter (VSC) HVDC technology was introduced in 1997 and since then has been characterised by continuously increasing power transfer capabilities. Significant developments have taken place in the area of dc cables including the introduction of extruded and mass impregnated polypropylene paper laminate (MI PPL) insulation technologies. New devices are emerging, such as the HVDC circuit-breaker. The present document aims to anticipate how the capability of the key technology areas might develop in coming years and provide an indication of technology availability by year in order to inform planning decisions.
