Our ambition is to ensure the effective and efficient connection of low-carbon technologies at pace to deliver net zero, whilst driving value for end consumers.
Over recent years, we have witnessed significant and rapid change in the energy landscape, including the type and volume of developments wanting to connect to the transmission network.
These changes in the industry have brought challenges, notably a hugely oversubscribed pipeline of customers wanting to connect to the network, resulting in increasing timescales being offered for connections.
There is a collaborative effort across industry to address the connections challenge, of which we have been supporting the ESO in the delivery of their 5-point plan to accelerate connections and development of a new connections process. The ESO's latest process recommendations have now been published here. We have also been working closely with the ENA as part of their 3-point plan to improve connections for distribution customers.
Ofgem have approved new Queue Management policy arrangements which will be applied to all new and existing connections projects. Find out more here.
Understanding the connections challenge
We believe the current connections challenge is made up of two areas:
The Market (directed by policy)
An open market for generation and demand which drives developers to apply only to secure their place in the pipeline as in many cases the connection timescales cause long lead times.
The Contract (governed by the process)
The connection agreement is captured within a contract which currently lacks required, consistent obligations for developers to demonstrate progress. This therefore prevents capacity being re-allocated accordingly, which would help to avoid viable connections being delayed by non-progressing projects.
The Physical Works (the products provided to facilitate a connection)
A physical connection ‘socket’ to connect a customer (e.g., a substation bay) and potentially increasing the size or number of ‘wires’ (overhead lines or cables) may be needed to support additional required capacity for specific projects. This results in inefficient allocation of works as they are linked to the requirements of contracted customers, reserving capacity for projects, and potentially blocking access for others, rather than focusing on strategic physical works where they are needed across the network.
Arguably, the biggest problem currently faced by all stakeholders in the connections landscape is the size of the contracted background of connections.
In England and Wales, the connections pipeline currently stands (as of November 2023) at 500GW, comprising over 700 contractual agreements, and is continuing to grow at an accelerated rate. With this representing significantly more than we will need to connect under any credible future energy needs scenario and to support wider interconnector needs, it causes a great deal of uncertainty. The below graph indicates the increase in new applications in the past few years.
For example, this volume of applications triggers the need for more than 50 new substations to be built, which is unnecessary for current or future network needs and a huge investment of resource- causing further delays to future projects.
We believe successful reform must deliver:
Change is required at pace to ensure long-term security of supply, energy resilience and affordability, whilst driving economic growth, creating a jobs and skills revolution, and establishing a more energy independent UK.
Some of these are initiatives led by NGET, and others are spearheaded by the ESO through their reform of the connections process.
NGET has identified the need to build the connection ‘sockets’ first, which will create capacity hubs and a long-term aim of providing customers with understanding of planned capacity ahead of their applications to inform and strengthen their investment decisions.
NGET is leading on developing a new standardised modular connection ‘socket’ for customers, suitable for many types of project, enabling faster and more flexible connections.
The ESO is working on ensuring projects meet certain key requirements before being granted a place in the connections pipeline, e.g., securing land rights, should enable resources, time, investment, and capacity to be allocated to projects which are most likely to connect. The latest updates on the ESO recommendations for a new connections process have been published here
The Queue Management code modification as led by the ESO will ensure milestones are applied to projects and if milestones are missed, reallocate capacity to progressing projects. Find out more about Queue Management here.
To realise the benefits of a new connections regime and address the well documented issues with grid connections, NGET advocates for urgent action to address the pipeline of contracted connections to either:
