Planning your connection

Here you’ll find information on how to get connected to the transmission system and guidance with your application to the Electricity System Operator (ESO). This short video will show you how to approach your connection research.

Planning your connection

When researching options for your energy project, you may find it useful to visit our network capacity map and use our quick cost estimator. These tools will give you the locations that could meet your needs and an estimated cost of the connection. Our connection charges overview provides an explanation of the charges you’ll need to pay.  

There are other factors you’ll also need to consider, such as financial securities – you’ll need to have these in place for any connection project that involves us delivering work for you.  

In terms of planning and consents, there are approvals that may be required from different permitting bodies when building new energy infrastructure. 

Get in touch 

After you’ve considered your options, we strongly recommend you make an enquiry with us to discuss your connection requirements.
