The new 132kV indoor substation connects the local grid operator UK Power Networks (UKPN) to National Grid’s high voltage transmission network, delivering electricity for distribution to 20,000 homes in the area.

Local low carbon transport services are also supported by National Grid’s new substation, with power delivered to a nearby Network Rail feeder station to support electrified train routes.

The Visual Impact Provision project in Eryri National Park aims to reduce the visual impact of the overhead electricity line across the Dwyryd Estuary from Minffordd to Llandecwyn. National Grid has worked closely with stakeholders and the local community to implement the project, which includes constructing two new tunnel head houses, which will provide access to the tunnel, along with a sealing end compound to connect the underground cables with the remaining overhead line. 

LionLink and Nautilus are pilot projects, defined as Offshore Hybrid Assets. They would not only connect national transmission systems, but also offshore wind farms based in Dutch and Belgian territorial waters, respectively. Both potential projects are first-of-a-kind, reflecting the same technological innovation required to deliver the longest land and subsea interconnector in the world, National Grid’s Viking Link. LionLink is being developed with Dutch transmission system operator, TenneT, and Nautilus is being developed with Belgian transmission operator, Elia. 

Lakeside Energy Park’s 100MW/200MWh facility is now the largest transmission connected BESS project in the UK following energisation.

The new facility will boost the capacity and flexibility of the network, helping to balance the system by soaking up surplus clean electricity and discharging it back when the grid needs it.

To ensure a safe connection, National Grid, working with its contractor Omexom, upgraded its Drax 132kV substation to accommodate the additional clean power.

The transformer, weighing 155-tonnes – the equivalent of 25 African elephants – will make its way from the Port of Tilbury on the evening of Saturday 16 November and arrive at the substation in the early hours of Sunday 17 November 2024.

Transformers play a vital role in helping to ensure the UK continues to enjoy safe and reliable energy supplies, stepping voltage up or down so electricity can be efficiently transmitted from power generators or safely distributed to homes and businesses via regional networks.

The Eastern Green Link (EGL) Collaboration Centre will bring together employees from the SSEN Transmission and National Grid Electricity Transmission Joint Venture (JV) – and the supply chain partners that they have appointed – to deliver the EGL series of electricity transmission subsea superhighways, starting with EGL2, the construction of which commenced in October.

The facility has been designed with collaboration in mind, and includes:
