All Parties intending to buy or sell energy in the wholesale Single Electricity Market must be registered. SEMO's role is to facilitate and educate applicants as they complete the registration process.

Register to join the market

The set of rules which govern the Single Electricity Market is known as the Trading and Settlement Code. A set of Agreed Procedures provide further guidance and clarification on how the rules are to be deployed. Agreed Procedure 1 (AP 1) deals with all aspects of the registration process. Potential Participants should be familiar with this document before applying to register in the Single Electricity Market. 

Participant requirements and registration procedures are defined in the respective market codes and administered by the system and market operator. An industry guide has been published which provides detailed information on participant roles in each market.

Participants who are not currently registered in the SEM must complete the Balancing Market Registration Pack. The registration process consists of two major steps.

Step 1: Party registration

In order to trade in the Single Electricity Market, a company must register as a Party. An applicant becomes a Party to the Trading and Settlement Code upon completing Party Registration. A Party is bound by the rules, regulations and obligations as set out in the Trading and Settlement Code.
