The market operator's yearly remuneration is established in the corresponding Ministerial Order, which determines the electrical energy charges for each year. This regulation establishes that this remuneration:
- Will be funded with the prices charged by the market operator to production market agents, both generators as well as traders, direct consumers on the market, and system loading managers, who may act in the scope of the Iberian Electricity Market.
- Will be equally covered by, on one hand, the team of electrical power producers and, on the other, the team of traders, direct consumers on the market, and system loading managers.
Electric power producers must pay the Market Operator a fixed monthly amount (which is set in a Tariff Order each year, given in euros/MW) for their available power for each of the facilities with a net or installed capacity over 1 MW in the case of renewable sources, cogeneration, or waste facilities with a premium or specific remuneration scheme. The yield from a corresponding payment obligation comes into consideration when a facility is registered on the first day of each month.
OMIE calculates the remuneration corresponding to each production facility owner or the representative acting in their name by considering the information available in the database of the Ministry of Industry, Tourism and the Digital Agenda’s Electrical Energy Production Facilities Registry. Available power is calculated by applying the value of the average availability rate to each facility's net (or installed) power, per the system and technology as determined by the yearly Tariff Order.
Traders, direct consumers on the market, and system loading managers who act in the scope of the Iberian Electricity Market must pay the Market Operator a fixed monthly amount (which is set each year in a Tariff Order, given in euros/MWh) for each MWh that appears in the final schedule of each hour.
The information available on OMIE's system corresponding to the last final schedule program for each hour that has not been canceled (whether by system operators or the market operator) and, in its absence, the definitive daily viable schedule is taken into account in this calculation.
The Market Operator's Information System provides the detailed calculations of OMIE's remuneration for each production facility, or for the different bidding units by traders, direct consumers, and system loading managers.
OMIE will issue an invoice to each agent each month for OMIE’s corresponding remuneration, never before the first collection day after the third business day of the following month. To create the invoice, OMIE will consider the company information available to the market operator.
The invoice is issued electronically using an advanced electronic signature from the market operator, and it is published in XML format on the Market Operator's Information System, though it can also be viewed as a PDF.
More information is available in the documentation on the Market Operator's Information System.
Invoices can be downloaded from the Market Operator's Information System.
OMIE may include the monthly payment on the debit or credit note for the Market Participant's production on the daily market.
If the Market Participant does not have a weekly debit or credit note, they must make a direct payment to the account given on the invoice.
