This UK pro- ject will be completed in 2029 and will strengthen the country’s electricity grid with cleaner, more sustainable energy. In addition to its technical importance, the project represents a fundamental ad- vance in the resilience of the British elec- tricity grid. The new infrastructure will enable renewable electricity generated in different regions of thecountry to betrans- ported to large urban centres, ensuring a more reliable supply against a background of growing demand and the transition to low-carbon sources. This initiative, thus, actively contributes to the UK’s decarbon- isation targets.

This is all part of The Great Grid Upgrade, an initiative aimed at modernising the country’s elec- tricity infrastructure. The contract, valued at £230 million, involves the construction of a 2.2-kilometre tunnel that will allow 400 kV high-volt- age power lines to pass underthRie ver Thames, replacing the old cable tunnel from the 1960s. The works include two shafts, approximately 35 metres deep, tech- nical buildings, transition enclosures and cable termination compounds.
