Introduction
The High-Voltage Direct Current (HVDC) transmission industry is responsible for the transportation of electricity over long distances from power plants to distribution networks and large industrial consumers. This industry ensures that the generated electricity reaches end-users efficiently and reliably. High-voltage transmission involves the use of transmission lines and substations to manage the flow of electricity and maintain stability within the power grid. The industry provides the backbone infrastructure essential for delivering electricity to homes, businesses, and industries.
Main Segments Within the Industry
The high-voltage transmission industry is primarily categorized into two main segments: transmission lines and substations.
Transmission Lines
Transmission lines are high-voltage power lines that transport electricity over long distances.
Overhead Transmission Lines
- Objective: Transport electricity across long distances using overhead power lines.
- Process: Electricity generated at power plants is transmitted through high-voltage overhead lines supported by transmission towers. These lines can span hundreds of miles and are crucial for connecting remote power generation sites with urban and industrial centers.
- Example: The Pacific DC Intertie in the United States, which transmits electricity between Oregon and California.
Underground Transmission Lines
- Objective: Transport electricity in densely populated or environmentally sensitive areas.
- Process: High-voltage cables are buried underground to transport electricity where overhead lines are impractical. These lines are often used in urban areas to reduce visual impact and minimize land use.
- Example: The London Power Tunnels project, which involves extensive underground transmission infrastructure in the UK.
Substations
Substations are facilities that step down high-voltage electricity for distribution.

- Process: High-voltage electricity from transmission lines is received at substations, where transformers reduce the voltage to levels suitable for local distribution. The electricity is then sent to smaller substations or directly to consumers.
- Example: The North Bergen Substation in New Jersey, which steps down high-voltage electricity for distribution in the surrounding area.
Switching Substations
- Objective: Manage the routing of electricity within the transmission network.
- Process: Switching substations do not change the voltage but instead direct the flow of electricity between different transmission lines. They play a critical role in maintaining grid stability and reliability.
- Example: The Desert Star Energy Center Switching Station in Nevada, which connects various transmission lines in the region.
