If you want to connect to the transmission system, there are a number of charges you’ll need to pay – initially for your application, and then ongoing charges, all of which are collected by the Electricity System Operator ESO).
When you apply for a connection to the Electricity System Operator (ESO), there will be a charge for the application, depending on the size of your proposed scheme. The fees are set annually and published by the ESO.
Ongoing connection charges
Once your project is connected to the transmission system, you’ll need to pay ongoing charges that are collected by the ESO.
You can download the ESO's statement of charges which sets out the basis upon which charges will be made for the provision of our transmission services. These services include the planning, development, construction, maintenance and operation of new and modified connections to the transmission system.
