Joining the DTS

Download our DTS Connection Map for guidance on our connection process. 

There are two prerequisites to becoming a DTS user:

(1) Get a valid Market Participant Identifier (MPID) or Gas MDD Shortcode

The MPID is a four-letter code in electricity, and the SPAA MDD Shortcode is a three-letter code in gas. These codes are unique to your company, and are a means of identifying you in the market. If you do not have a Market Participant ID (MPID), we must confirm that Elexon has reserved an MPID for you and is processing your application. For SPAA MDD Shortcode, we require your MDD application to be approved by SPAA before we can proceed with setting up your gateway connection to the DTN.

For an electricity MPID please contact ELEXON by emailing for further information. For gas, SPAA MDD Shortcodes are issued by Xoserve through SPAA. If you require an MDD application, contact If you need to contact Xoserve, please email them at

(2) Complete and return the items in our DTS Connection Pack.

  1. If you are a gas market participant wishing to connect to the DTS in order to exchange NOSI and/or RET & SAR flows or if you are an electricity party or green deal party wishing to connect to the DTS, please download the DTS Connection Pack.
