Which bits of the CUSC apply to me and what other agreements may I have to sign?

Sections 1, 5, 6, 7, 8, 10 and 11 apply to all categories of signatory.

In relation to Sections 2 (Connection), 3 (Use of System) and 9 (Interconnectors) the following table sets out the applicability of those Sections in addition to the sections of general applicability:

	Category of User	Applicable CUSC Sections	Other Relevant Agreements
1	Power Station directly connected to the National Grid Transmission System	2 and 3	Bilateral Connection Agreement (Schedule 2 - Exhibit 1) Construction Agreement (Schedule 2 - Exhibit 3) Mandatory Services Agreement (Schedule 2 - Exhibit 4)

Users, when making a Connection Application or Use of System Application (in each case in the form of the relevant exhibit), should identify the category for which they are applying.

In all cases, parties who are not already CUSC Parties will be required to accede to the CUSC via the Accession Agreement (Exhibit A of the CUSC) in order to become a party to the CUSC Framework Agreement, which gives contractual effect to the CUSC.

If you intend to supply electricity in the UK you will require a Use of System Supply Offer and Confirmation Notice from National Grid (Exhibit G of the CUSC), this will be given following an application made to use the system (Exhibit F of the CUSC).

In order to supply electricity to the UK from abroad, or for Interconnector Error Administrators, you will require a Use of System Interconnector Offer and Confirmation Notice (Exhibit H of the CUSC), which will be given following an application to use the system (Exhibit F of the CUSC).
