As a result of the establishment of MIBEL (Iberian Electricity Market),
a series of procedures, rules and economic/technical requirements between Portugal and Spain have been harmonised.
The setting up of an Iberian Market Operator (OMI) was defined. This operator is responsible for the management of the MIBEL organized markets and is based on a bipolar interconnected structure:
OMIE (Spanish Centre) is responsible for day and intraday market management;
(Portuguese Centre) is responsible for the management of forward markets.
OMIE thus manages the Iberian day and intraday electricity markets where purchases and sales are carried out by market agents in sessions which aggregate, in a market splitting logic, the Spanish and Portuguese areas of MIBEL.
