1 Intro

This document provides a list of terms, abbreviations and documents (sources) related to the project. For each source document, we record the name, version, date and link.

2 Terms and Abbreviations

2.1 Terms

Most of these terms come from EUreg Transparency:

  • balancing reserves: all resources, if procured ex ante or in real time, or according to legal obligations, which are available to the TSO for balancing purposes;
  • balancing time unit: time period for which the price for balancing reserves is established;
  • bidding zone: largest geographical area within which market participants are able to exchange energy without capacity allocation;
  • capacity allocation: attribution of cross zonal capacity;
  • consumption unit: resource, which receives electrical energy for its own use, excluding TSOs and Distribution Systems Operators (DSOs);
  • control area: coherent part of the interconnected system, operated by a single system operator and shall include connected physical loads and/or generation units if any;
  • coordinated net transmission capacity: capacity calculation method based on the principle of assessing and defining ex ante a maximum energy exchange between adjacent bidding zones;
  • critical network element: network element either within a bidding zone or between bidding zones taken into account in the capacity calculation process, limiting the amount of power, that can be exchanged;
  • cross-control area balancing: balancing scheme where a TSO can receive bids for activation coming from other TSO's areas. It does not include re-dispatching or the delivery of emergency energy;
  • cross zonal capacity: capability of the interconnected system to accommodate energy transfer between bidding zones;
  • currency: is euro if at least one part of the bidding zone(s) concerned is part of a country in which euro is a legal tender. In any other case it is the local currency;
  • cut-off time: point in time, where TSOs have to confirm all matched nominations to the market. The cut-off time refers not only to daily or intra daily markets but also to the different markets that cover imbalance adjustments and reserve allocation;
  • countertrading: cross zonal exchange initiated by system operators between two bidding zones to relieve physical congestion;
  • data provider: entity that is sending the data to the central information transparency platform;
  • explicit allocation: allocation of cross zonal capacity only, without the energy transfer;
  • flow based parameters: the available margins on critical network elements with associated power transfer distribution factors;
  • generation unit: single electricity generator belonging to a production unit;
  • implicit allocation: congestion management method in which energy is obtained at the same time as cross zonal capacity;
  • market time unit: period for which the market price is established or the shortest possible common time period for the two bidding zones, if their market time units are different;
  • offered capacity: cross zonal capacity offered by the transmission capacity allocator to the market;
  • planned: means an event known ex ante by the primary owner of the data;
  • power transfer distribution factor: representation of the physical flow on a critical network element induced by the variation of the net position of a bidding zone;
  • primary owner of the data: entity, which creates the data;
  • production unit: facility for generation of electricity made up of a single generation unit or of an aggregation of generation units;
  • profile: a geographical boundary between one bidding zone and several neighbouring bidding zones;
  • redispatching: measure activated by one or several system operators by altering the generation and/or load pattern in order to change physical flows in the transmission system and relieve a physical congestion;
  • total load:, including losses without power used for energy storage, means a load equal to generation and any imports deducting any exports and power used for energy storage;
  • transmission capacity allocator: entity empowered by TSOs to manage the allocation of cross zonal capacities;
  • vertical load: total amount of power flowing out of the transmission network to the distribution networks, to directly connected final customers or to the consuming part of generation;
  • year-ahead forecast margin: difference between the yearly forecast of available generation capacity and the yearly forecast of maximum total load taking into account the forecast of total generation capacity, the forecast of availability of generation and the forecast of reserves contracted for system services;

Terms from IEC Electropedia:

  • power station (production unit, generating station, power plant, powerhouse): industrial facility for the generation of energy: electricity, useful heat, etc (601-03-01)
  • generator (generating unit): device that converts one form of energy to another: mechanical energy or sun light to electricity, etc (151-13-35)
  • wind farm: group of wind turbines in the same location used for production of electricity, located on agricultural or other land, or offshore (415-01-03)

2.2 Areas

The constituency of ENTSOE is broken up into a number of Domains/Areas according to different principles. See spec#areas for a detailed investigation of important Areas.

The kinds of Areas are listed below.

Sources: doc Areas (which shows numerous examples of the interplay of different areas), paper Transparency; abbreviations in doc SFTP and lookup EIC; Bidding zone configuration technical report (shows how bidding zones are defined and their future evolution)

  • Bidding Zone, BZN: largest geographical area in which there is a uniform spot price, in which Market Participants can exchange energy without Capacity Allocation.
  • Control Area, CA=CTA: coherent part of the interconnected system, operated by a single system operator and shall include connected physical loads and/or generation units
  • Member State (Country), CTY: EU member state or a neighboring state
  • Market Balance Area, MBA: geographic area in which there is a uniform balancing energy price. Consists of one or more Metering Grid Areas with common market rules for which the settlement responsible party carries out a balance settlement and which has the same price for imbalance. May also be defined due to bottlenecks.
  • Scheduling Area, SCA: same as Bidding Zone, except if there is more than one Responsibility Area within this Bidding Zone. In the latter case, the Scheduling Area equals Responsibility Area or a group of Responsibility Areas

Here you can see how the zones are distributed based on the Area type: EIC area codes map

The following kinds of areas are less relevant for Transparency and are listed in doc Functions:

  • Balance Group
  • Border Area
  • Capacity Calculation Region
  • Control Block: composition of one or more Control Areas, working together to ensure the load frequency control on behalf of RGCE
  • Coordination Center Zone
  • Distribution Network Area
  • FRR Sharing Region
  • LFC Area, LFA: TODO (FCR Shares of Capacity)
  • LFC Block, LFB: TODO (FCR Shares of Capacity)
  • Local Market Area
  • Market Area: same as MBA?
  • Metering Grid Area
  • Regional Outage Area
  • Synchronous Area: area covered by interconnected TSOs with a common System Frequency in a steady state.
