Applying for a connection
Connecting is suitable for a wide range of gas customers, including the largest consumers such as distribution networks, power stations, and large industrial enterprises. We will also connect newer forms of indigenous gas such as biomethane producers, small gas generators, shale and compressed natural gas users; we will open applications for this from late 2018. We offer three types of connection: entry, exit, and storage. All new connections follow the Application to Offer (A2O) process.
Who should apply
Transmission connections are appropriate for a range of gas users, including:
gas distribution networks;
major industrial premises, such as power stations;
combined heat and power (CHP) schemes;
a few major energy-intensive industries; and
lower-flow gas users such as biomethane, small gas generators, shale and compressed natural gas (for application in late 2018).
How to apply
To start the process, you will need to:
submit a correctly completed and technically competent application form; and
deposit an application fee with us as cleared funds, as stated in Section Y of the Transportation Principal Document in the UNC.
How long it takes
The period from clock start to issue offer depends on the type of offer to be made.
An initial connection offer (ICO) will be made within two months;
A full connection offer (FCO) requiring a conceptual design study will be made within six months.
A full connection offer (FCO) requiring a feasibility study will provide the feasibility study report within three months, and the offer six months following acceptance of the report by the customer.
