ESB Networks newly built transmission stations in the South West of Ireland required a deep grid reinforcement to facilitate the interconnection of two bulk power nodes on each River Shannon bank.

The Challenge 

To construct new 220 kV cable circuits between Kilpaddoge 220 kV station and Moneypoint 400 kV station via a land and submarine cable. 

The successful completion of the project included the installation, commissioning and energisation of the following across the River Shannon Estuary:  

• 21 kilometres of 220 kV cross-linked polyethene (XLPE) submarine cable.  
• 4 kilometres of 220 kV land cable installation including spare lengths.   
• Fibre optic connections.
