Connecting with confidence
We will use our technical expertise and extensive high voltage network to assist you in connecting to the national grid in England and Wales, whether you are a demand or generation customer. We are extremely keen to talk to you about your business requirements, so you can connect with confidence.
A network fit for today - and the future
As the owner of the high voltage electricity transmission network in England and Wales, we guarantee the availability and reliability of our equipment so that generators, distributors, and some demand customers have access 24 hours a day, 365 days a year. Our network consists of approximately 7,200 kilometres (4,474 miles) of overhead line, 1,500 kilometres (932 miles) of underground cable, and more than 300 substations.
This infrastructure is the backbone of our society. And in our Electricity Transmission business, we have more than 2,000 professionals who are developing, optimising and improving that infrastructure. Through world-class asset management and exceptional levels of safety, we connect people to the energy they use today – whether it’s heat and light for their homes or to keep factories and offices running.
The electricity transmission network also has a central role to play in the future energy mix, with evolving roles enabling a range of possible energy futures to the long-term benefit of consumers. This includes providing secure and affordable energy, while meeting ambitious low-carbon energy targets and connecting new sources of energy to the people who use them. It also includes enabling the decarbonisation of heat and transport.
The unprecedented rate of change in the energy landscape means we have to be versatile and highly innovative. Through lean asset design, effective risk management, and efficient asset management techniques, we are boosting network efficiency and removing costs from our business - all of which creates value for our customers and end consumers. We’re also investing efficiently, so we can maintain network reliability above 99.9999%, and enable new customers to connect to our network.
And we care for the environments within which we operate, working hard to reduce the impact of our electricity infrastructure across our precious landscapes.
We invest time to listen to our customers, so we can understand and meet their needs – providing a reliable, affordable electricity network that benefits our customers and consumers alike. At the same time, we continue to involve local communities in the decision-making process when we’re building new assets, or refurbishing existing ones.
Over the next decade we expect to step up our work to modernise our energy infrastructure, doing so at highly competitive prices, so we can improve the environment and prosperity of our country. We will do this through continued strong asset management, being truly efficient and innovative, and listening to our customers, making sure we provide continually improving levels of service.
We work with both generator and demand customers to meet their needs from different scale projects in order to meet customers’ requirements. Though connecting HV assets isn’t always a straightforward business, we will guide you every step of the way whether it's for additional demand, generation, or ancillary service provisions. We are here to help.
When you embark on a new connection project, one of the first things you need to be aware of is the current availability of capacity on the network. The Customer Connection Interface Tool (CCIT) will provide you with a heat-map overview of our existing capacity.
