|Coordinated net transmission capacity (CNTC) approach|
|European Union Electricity Market Glossary|
Coordinated net transmission capacity (CNTC) approach is the capacity calculation method based on the principle of assessing and defining ex ante a maximum energy exchange between adjacent bidding zones (Article 2(8) of the Regulation establishing a Guideline on Capacity Allocation and Congestion Management - CACM (Regulation on market coupling)).
Both these methods are intended to maximise tradable cross-zonal capacity while safeguarding the operational security standards of the transmission system, also both result in the determination of possible commercial capacity that can be allocated for each direction on each bidding zone border.
However, the distinctive features of the CNTC method are:
- the actual exchange between two given bidding zones is not dependent on the exchanges across adjacent borders,
It is an acceptable capacity calculation method for non-meshed networks, provided that a sufficient level of coordination is applied (ACER/CEER Annual Report on the Results of Monitoring the Internal Electricity and Gas Markets in 2016 (Electricity Wholesale Markets Volume, October 2017, p. 22).
CNTC refers to one of the two possible capacity calculation methodologies envisaged in the CACM (in addition to the flow-based approach), while NTC is used to refer to existing capacity calculation methodologies, which are not necessarily as coordinated as required by the CACM.
