Key concepts
- Market agent
- Who books: the market subject (BRP) that submits a unit’s offers and settles with the operator. May be the asset owner or a representative.
- Owner
- Who owns the physical asset. When it differs from the agent, market revenue is booked under the agent but the economic outcome belongs to the owner (source: OMIE / manual curation, with a quality indicator).
- Group
- Corporate group: gathers the companies (market subjects) under one parent. The level at which winners and losers are analysed.
- UP / UF
- Programming unit (UP): the unit scheduled and settled in the market. Physical unit (UF): the real equipment (thermal group, wind farm). One UP may bundle several UFs.
