Demand Facility
European Union Electricity Market Glossary

 

 

 

 

'Demand Facility' means a facility which consumes electrical energy and is connected at one or more connection points to the transmission or distribution system.

 

A distribution system and/or auxiliary supplies of a Power Generating Module (PGM) do not constitute a Demand Facility (Article 2(1) of the Demand Connection Code (DCC)).

 

Winter Energy Package (Annex to the Proposal for a Regulation of the European Parliament and of the Council on the internal market for electricity (recast), 30.11.2016, COM(2016) 861 final 2016/0379 (COD)) provides for the regional outage coordination of Demand Facilities.

 

This task is entrusted to Regional Operational Centres (ROCs).

 

Pursuant to the said draft each ROC would perform outage coordination "in order to monitor the availability status of the relevant assets and coordinate their availability plans to ensure the operational security of the transmission system, while maximizing the capacity of the interconnectors and/or the transmission systems affecting cross-zonal flows."

 

Each Regional Operational Centre would also maintain a single list of relevant grid elements, Demand Facilities and Power Generating Modules of the system operation region and make it available on the ENTSO for Electricity operational planning data environment.

 

Further, each ROC would carry out the following activities related to outage coordination in the system operation region:


(a) assess outage planning compatibility using all Transmission System Operators' (TSOs') year-ahead availability plans;


(b) provide the transmission system operators of the system operation region with a list of detected planning incompatibilities and the solutions it proposes to solve the incompatibilities.

 

 

Relevant Demand Facilities

 

 

Network Code on System Operation In Articles 84 - 86 envisions the establishment of the lists of "relevant Demand Facilities" (along with the list of "relevant Power Generating Modules").

 

According to Article 103(3) of the Network Code on System Operation each Demand Facility owner must ensure that all relevant Demand Facilities it owns and which are declared ‘unavailable’ do not consume electricity.

Articles 84 - 86

 

Article 84
Methodology for assessing the relevance of assets for outage coordination


1.   By 12 months after entry into force of this Regulation, all TSOs shall jointly develop a methodology at least per synchronous area, for assessing the relevance for the outage coordination of power generating modules, demand facilities, and grid elements located in a transmission system or in a distribution system, including closed distribution systems.


2.   The methodology referred to in paragraph 1 shall be based on qualitative and quantitative aspects that identify the impact on a TSO's control area of the availability status of either power generating modules, demand facilities, or grid elements which are located in a transmission system or in a distribution system including a closed distribution system, and which are connected directly or indirectly to another TSO's control area and in particular on:


(a) quantitative aspects based on the evaluation of changes of electrical values such as voltages, power flows, rotor angle on at least one grid element of a TSO's control area, due to the change of availability status of a potential relevant asset located in another control area. That evaluation shall take place on the basis of year-ahead common grid models;


(b) thresholds on the sensitivity of the electrical values referred to in point (a), against which to assess the relevance of an asset. Those thresholds shall be harmonised at least per synchronous area;


(c) capacity of potential relevant power generating modules or demand facilities to qualify as SGUs;


(d) qualitative aspects such as, but not limited to, the size and proximity to the borders of a control area of potential relevant power generating modules, demand facilities or grid elements;


(e) systematic relevance of all grid elements located in a transmission system or in a distribution system which connect different control areas; and


(f) systematic relevance of all critical network elements.


3.   The methodology developed pursuant to paragraph 1 shall be consistent with the methods for assessing the influence of transmission system elements and SGUs located outside of a TSO's control area established in accordance with Article 75(1)(a).


Article 85
Lists of relevant power generating modules and relevant demand facilities


1.   By 3 months after the approval of the methodology for assessing the relevance of assets for outage coordination in Article 84(1), all TSOs of each outage coordination region shall jointly assess the relevance of power generating modules and demand facilities for outage coordination on the basis of this methodology, and establish a single list, for each outage coordination region, of relevant power generating modules and relevant demand facilities.


2.   All TSOs of an outage coordination region shall jointly make the list of relevant power generating modules and relevant demand facilities of that outage coordination region available on the ENTSO for Electricity operational planning data environment.


3.   Each TSO shall notify to its regulatory authority the list of relevant power generating modules and relevant demand facilities for each outage coordination region in which it participates.


4.   For each internal relevant asset which is a power generating module or demand facility, the TSO shall:


(a) inform the owner of the relevant power generating module or relevant demand facility about its inclusion in the list;


(b) inform DSOs about the relevant power generating modules and the relevant demand facilities which are connected to their distribution system; and


(c) inform CDSOs about the relevant power generating modules and the relevant demand facilities which are connected to their closed distribution system.


Article 86
Update of the lists of relevant power generating modules and relevant demand facilities


1.   Before 1 July of each calendar year, all TSOs of each outage coordination region shall jointly re-assess the relevance of power generating modules and demand facilities for outage coordination on the basis of the methodology developed in accordance with Article 84(1).


2.   Where necessary, all TSOs of each outage coordination region shall jointly decide to update the list of relevant power generating modules and relevant demand facilities of that outage coordination region before 1 August of each calendar year.
3.   All TSOs of an outage coordination region shall make the updated list of that outage coordination region available on the ENTSO for Electricity operational planning data environment.


4.   Each TSO of an outage coordination region shall inform the parties referred to in Article 85(4) about the content of the updated list.
