Recitals 33 - 37

 

(33) The coordination between transmission system operators at regional level has been formalised with the mandatory participation of transmission system operators in regional security coordinators, which should be complemented by an enhanced institutional framework via the establishment of regional operational centres. The creation of regional operational centres should take into account existing regional coordination initiatives and support the increasingly integrated operation of electricity systems across the Union, ensuring their efficient and secure performance.

 

(34) The geographical scope of regional operational centres should allow them to play an effective coordination role by optimising the operations of transmission system operators over larger regions.

 

(35) Regional operational centres should carry out functions where their regionalisation brings added value compared to functions performed at national level. The functions of regional operational centres should cover the functions carried out by regional security coordinators as well as additional system operation, market operation and risk preparedness functions. The functions carried out by regional operational centres should exclude real time operation of the electricity system.

 

(36) Regional operational centres should primarily act in the interest of system and market operation of the region over the interests of any single entity. Hence, regional operational centres should be entrusted with decision-making powers to act and to direct actions to be taken by transmission system operators of the system operation region for certain functions and with an enhanced advisory role for the remaining
functions.

 

(37) ENTSO for Electricity should ensure that the actions of regional operational centres are coordinated across the regions' boundaries.

Key Recommendations for the Clean Energy Package, ENTSO-E, 15 March 2017, p. 1


Key Recommendation 1: Regional Operation Centres (ROCs)

 

- Regional cooperation is in TSOs’ DNA. Introduced over ten years ago on the basis of voluntary initiatives of the TSOs, regional TSO coordination is now mandatory through EU regulations (System Operation Guideline). In the past years, TSOs have successfully developed several regional centres (e.g., CORESO, TSC), which provide TSOs with a set of crucial services for operation coordination.

 

Whilst we welcome the Commission’s support for regional cooperation, there is a need to improve several provisions in the design of ROCs:

 

- The current proposals risk interfering with the effective implementation of the System Operation Guideline, according to which all Regional Security Coordinators will provide five regionally coordinated services for market and security by 2019 (Electricity Reg, Art 55 (p); Art 31-44). 


 

- Splitting the liability of the operation of the power system between national TSOs and regional entities introduces a very risky legal and political gap with concerns over the operational security of the power system. First, having binding powers given to ROCs is incompatible with Member State responsibilities in terms of security of supply. Secondly, technically speaking, liability cannot be split by different time-horizons, nor by extracting a subset of elements and processes strongly interdependent with elements and processes under TSO responsibility (Art 44). 


 

- The feasibility and benefits of transferring the five existing standard services and new functions to the ROCs has not been properly assessed. Such assessment is critical and should be carried out with TSOs who have the experience and know-how, both from national power systems and from regional coordination. 


 

- The proposals concerning regional delimitation lead to some very large regions covered by one regional centre. Given the system complexity and uncertainty, this requirement could lead to significant operational risks affecting system reliability and resilience. (Art 33) 

Mandatory regional cooperation of TSOs through Regional Security Coordinators, which TSOs are implementing today, is dynamic and flexible and can be enhanced further when the need arises.
