Power transmission

Across the land and below the oceans, electricity transmission networks are a vital part of the energy transition

Transmission networks are responsible for the bulk transfer of electricity between sources of generation and sources of demand. Modern transmission systems are miracles of connectivity, linking regions, nations and remote generation assets – often over hundreds of kilometres.

The transmission landscape is changing in several ways.

• First, there is a need to accommodate a forecast rise in electricity demand of more than 40% over the next 20 years.
• Second, there is a growing requirement for high-capacity transmission with minimal losses. Offshore wind is a major driver, there is also an increasing need for long-distance HVDC subsea interconnectors. These play a crucial role in ensuring the optimal functioning of energy markets.
• Third, there is a growing need for cross-border transmission between national energy systems.

The high-voltage interconnection market (subsea and land) is set to grow by 14.13% per year.

Overarching all of this is the need for resilience. The increase of the high-voltage grid, the addition of new interconnection lines between countries and continents contributes to a better reliability and a greater flexibility of the grid.

As electricity becomes the primary power source for everything – including heating, transport and industry – the reliability of transmission infrastructure will become more important than ever.
