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.
