Submission of Generation and Demand Capacity for Summer 2023 BSC Season

The Summer BSC Season begins on 1 June 2023 and if you are using the Elexon Kinnect Customer Solution, the deadline for submitting your Generation and Demand Capacity (GC/DC) values for the Season is 16 May 2023.

Submission using Elexon Kinnect

Since the launch of the Elexon Kinnect Customer Solution, Category A Authorised Signatories, or customers who have been set up on the system by their company’s Category A Authorised Signatory, can now submit and manage their GC/DC values on the platform, via the Manage QMijs screen.

Submission using the BSCP15/4.3 form

If you are not set up on Elexon Kinnect yet, or if you plan to submit your values after 16 May 2023, you can submit values using the BSCP15/4.3 form signed by a Category A or F Authorised Signatory (see BSCP38 ‘Authorisations’ for information on Signatories).

Please note that you will then need to send the values to the Central Registration Agent (CRA) using the email address [email protected].

Please ensure the values are consistent with the energy units (MW or MWh) for the relevant column of the form. Even if the values are identical to the last BSC Season you need to submit values for the new Season.
