North West Coast Connections

North West

We are developing the North West Coast Connections (NWCC) project because we need to connect and export the electricity that will be generated by Moorside, the new nuclear power station NuGeneration Ltd is proposing to build near Sellafield in West Cumbria.

There are existing pylon lines which run around the west coast of Cumbria distributing the electricity used by homes and businesses across the region. Operating at 132kV and below, these lines cannot carry the amount of electricity a power station the size of Moorside will generate.

This means we need to build a new high voltage connection from Moorside to our existing national electricity transmission system. The closest points on our network where these circuits can connect are over 50 kilometres (31 miles) away from the site.

Our proposed connection

The connection we’re proposing to build is around 164 kilometres (102 miles) long. It broadly follows the path taken by existing Electricity North West (ENW) pylon lines running around the coast of west Cumbria between Carlisle and the Furness peninsula, before going through a tunnel under Morecambe Bay to Lancashire. The total cost of building our proposed connection will be around £2.8 billion. Approximately £1.9 billion of this is investment all along the route to reduce its potential effect.
