Joining the Market
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 market entrants as they complete the registration process.
Note for Intraday Trading/EWIC Registration:
Already Registered? If you are already registered as a participant in the SEM and in the ROI jurisdiction and you now wish to trade on the EWIC when it goes live in the market, then this is possible by using the current process of registering a new unit; see step 2 below. This means that we are simply adding a new PT or account (if you are already trading as a generator, then you will already have a generator account which can be used for additional interconnector units). You will need to fill out an interconnector user participation notice form and pay the fee that applies to adding the additional unit (Please note post Intraday Trading this will increase to three Participation notices but one fee will remain).
Not Registered yet? If you are not registered in the ROI jurisdiction or are new to the SEM and not yet registered at Party level then it is strongly advised that you start that process ASAP. You will need to obtain an ROI VAT number if you are not based in the jurisdiction and accede to the Code if you are not yet a Party. Upon completing Party Registration, a Party is bound by the rules, regulations and obligation as set out in the Trading and Settlement Code. The same process applies for any Participant wishing to take part in the Intraday auctions on the Moyle. Please note the importance of having the banking arrangements and VAT number for the relevant jurisdiction.
The registration process consists of two major steps:
Step 1: Party Registration (for accession to the Code): An applicant becomes a Party to the Trading and Settlement Code upon completing Party Registration. A Party is bound by the rules, regulations and obligation as set out in the
Trading and Settlement Code
Step 2: Unit Registration (for participation in the market): A Party becomes a Participant in the Single Electricity Market by registering Unit(s). This allows the participant to sell electricity into the pool, or consume electricity from the pool. To understand how the market works please view our
