TechnologyProject Description

How HVDC supports integration of Renewables

• Capable of long distance interconnections for remotely located resources

• Low line losses for remotely located resources

• Best available technology for interconnection to weak grid interconnection points

• Digital, fast control over the direction of flow – for a grid increasingly used for shifting available intermittent resources

• "Ride-through" capability
