Connecting the windfarms to the electricity network

The point of interconnection

The Morecambe and Morgan offshore wind farms are expected to connect to the electricity transmission network via an existing National Grid substation at Penwortham in Lancashire.

This is known as the point of interconnection (POI) and was identified through a rigorous site selection process undertaken by National Grid, which manages the electricity transmission network.

The onshore substations

To connect to the electricity transmission network we will need to construct new substations. These new substations are needed to enable us to transform the power supplied from the windfarms to connect into the grid.

To maintain electrical independence, one substation will be required for the Morgan Offshore Wind Project and one for the Morecambe Offshore Windfarm.

We will conduct a thorough site selection process, taking into account factors such as proximity to homes, environmental constraints and technical constraints.

Further engagement will be planned and further details will be available as this process progresses.

We would like you to provide us with any feedback or local information for consideration in the site selection process.

How do we choose a cable route?

The route planning and site selection process for the onshore cable corridor route involves the identification of a range of engineering, commercial, environmental, land interest and community related principles and constraints.

These are then used to identify potential onshore cable corridor route options for consideration.

Engineering considerations will include aspects such as technical feasibility and the identification of the shortest and most direct route, wherever practicable.

Examples of environmental constraints will include consideration of designated sites, protected species, landscape and cultural considerations.

Other constraints that will also be considered include the location of existing utilities and other local infrastructure.

During the process we will also be seeking feedback from landowners, local communities and bodies such as local planning authorities, the Environment Agency and Historic England, to help us refine our proposals.

1. The proposed Morecambe and Morgan transmission assets infrastructure will include an onshore cable corridor route within which the onshore export cables will be buried.

Do you have any comments or feedback related to the routing and site selection of the onshore cable corridor within the Scoping boundary? For example, this may relate to ecology, cultural heritage, residential properties or land use.
