Nelson investment

We're delivering the largest ever investment in the North West’s power network, investing over £1bn between 2023 and 2028 – including a £33m programme of key projects across Lancashire.

We're committed to maintaining and improving the network through our capital investment programme

Engineers have commenced work which will see £4m worth of upgrades carried out on the East Lancashire power network.

As part of our capital investment programme, 6km of underground electricity cables will be replaced as will assets within a substation in Nelson.

The work taking place on the 33,000-volt network will future-proof the network across Burnley and Nelson whilst also enhancing reliability, resilience and enabling more low carbon technologies like heat pumps and electric vehicle charging.

Once complete, more than 39,000 homes and businesses are expected to benefit from the new and improved infrastructure.

This £4m investment will future-proof Nelson’s and Burnley’s electricity infrastructure and improve resilience and reliability
The project supports our commitment to reinforcing the network and futureproofing for increased demand from low carbon technologies
We are working closely with Lancashire County Council to coordinate works and minimise disruption
Road closures and diversions may be necessary but will be carefully planned and communicated in advance in collaboration with local authorities
We are committed to keeping residents, businesses, and commuters informed every step of the way.

Engineers started work on Monday 9 June 2025, on Fleet Street which progressed to Charles Street. Work is now taking place on Eastern Avenue which will progress towards Casterton Avenue and Colne Road in the coming weeks.

We will initially lay underground ducts to house the cables before returning later in the year to pull the cable into place and connect them to the network.

Work is expected to last 12 months, all work has been agreed with the local authorities and we've hand delivered letters to customers with details of any traffic management.

What Is an Interconnector?

An interconnector is a high-voltage cable that links two parts of the electricity network. It allows electricity to flow between areas, helping balance supply and demand and improving overall grid performance.

How It Works

Electricity is generated from various sources, including renewables.
The interconnector transfers electricity between Nelson and Burnley, depending on where it’s needed most.
Smart systems manage the flow to ensure efficiency and stability.

Why It Matters for Nelson and Burnley

Improved Reliability
Reduces the risk of power cuts by allowing electricity to be shared between areas.
Supports Growth
Enables future housing, business, and infrastructure developments by increasing network capacity.
Cleaner Energy
Helps integrate more renewable energy into the local grid.
Cost Efficiency
Reduces the need for expensive upgrades elsewhere by making better use of existing infrastructure.
