What’s Involved in New Power Connections for Commercial Sites?

If you are developing a commercial site, one of the first things you need to consider is how the property will be powered. A new power connection is not just a case of getting electricity to the site. It is a structured process involving design, approvals, infrastructure and coordination with the local network.

At Northern HV, we support businesses, developers and contractors through the full process, from initial enquiry through to energisation.

What Is a New Power Connection?

A new power connection is the process of connecting a property or development to the electricity network so it can receive power safely and reliably.

This might be for a brand new commercial unit, a redevelopment project or an upgrade to an existing supply. In many cases, especially for larger sites, this involves high voltage infrastructure, substations and specialist engineering work.

Who Is Involved in the Process?

There are typically two key parties involved in delivering a new power connection. The Distribution Network Operator, often referred to as the DNO, owns and operates the local electricity network. They are responsible for approving the connection and adopting the infrastructure once complete.

Alongside this, an Independent Connection Provider, such as Northern HV, can design and install the required infrastructure. Working with an ICP often gives clients more flexibility and can help move projects forward more efficiently.

The Process of a New Power Connection

Every project is different, but the overall process tends to follow a clear structure from start to finish. It begins with an initial enquiry, where the power requirements of the site are assessed. This is a crucial stage, as it determines the scale of infrastructure needed and whether high voltage systems will be required.

From there, a detailed design is produced. This outlines how the site will connect to the network, including cable routes, connection points and any substation requirements. Once the design is agreed, costs are provided and approvals are secured before work begins.

Installation then takes place on site. This can involve anything from cable installation through to full substation builds, depending on the complexity of the project. Once installed, the system is tested and commissioned to ensure everything operates safely and as intended.

The final stage is energisation, where the system is connected to the live network and handed over for use.

How Long Does a New Power Connection Take?

The timeframe for a new power connection can vary significantly depending on the project. Smaller connections may be completed relatively quickly, but larger commercial or industrial developments often require several months. This is due to the number of stages involved and the need for approvals, design work and coordination with network operators.

Delays are often linked to planning, network capacity or site conditions, which is why early engagement is so important.

How Much Does a New Power Connection Cost?

The cost of a new power connection depends on a range of factors and can vary from project to project.

The main influences tend to be:

• The distance to the nearest connection point
• The amount of power required
• Whether a substation is needed
• The complexity of installation and groundworks

For larger commercial sites, costs can quickly increase where additional infrastructure is required. A full design and assessment is always needed to provide an accurate figure.

Why Work With an Independent Connection Provider?

Choosing to work with an Independent Connection Provider can make a noticeable difference to how a project is delivered. Rather than relying solely on the DNO, an ICP allows you to take a more proactive approach. This often results in better control over timelines, clearer communication and a more tailored solution for the site.

At Northern HV, we manage the process from start to finish, acting as a single point of contact and ensuring all work is delivered in line with industry standards.

Common Challenges with Power Connections

New power connections can become complex if they are not planned and managed correctly. Issues often arise around network capacity, unexpected site conditions or delays in approvals. Changes to design part way through a project can also have a knock on effect on both cost and timeline.

Working with experienced engineers from the outset helps to reduce these risks and keeps the project moving in the right direction.
