Founded in 2008 in Brussels, close to the European Commission, Coreso launched its operations in February 2009. At that time, it was one of the first technical coordination centres in continental Europe shared by multiple TSOs.
At the ENTSO-E Assembly in late 2015, the European Transmission System Operators (TSOs) approved and signed an all-TSO Multilateral Agreement for Regional Security Coordination Initiative (RSCI)-based TSO cooperation. With this mandatory contractual framework, TSOs across Europe have committed to establishing five regional coordination services and setting up or appointing RSCs to perform the following coordination services:
Since then, two European Union regulations (guideline on electricity transmission system operation or System Operation Guideline (SOGL), and guideline on Capacity Allocation & Congestion Management (CACM)) have been published to define recommendations and further describe the 5 mandatory services to be delivered by RSCs.
Thanks to these regulatory and contractual frameworks, RSCs are no longer voluntary initiatives: RSC official roles and responsibilities have been totally formalised.
Europe aiming for green transition and digital transformation, RSCs will evolve by mid-2022 into Regional Coordination Centres (RCCs). Established in the Clean Energy Package (CEP), this evolution reinforces their key coordination role. In addition to the five regional coordination services, RCCs must perform a new set of mandatory tasks which are currently being defined.
When the health situation in Belgium stabilised in June, Coreso offices were reopened with an office rotation plan to limit presence at the office (max 1 day per week and 20% of employees), with a strong focus on sustainable measures to protect employees from COVID-19 contamination.
As part of Coreso´s commitment to operational excellence, the Coreso coordination room was upgraded and future-proofed. Refurbishment works were performed from 3 November until 23 December 2020 to improve operational processes and to enable our operators to perform their processes with a higher efficiency.
Coreso was hit by the coronavirus pandemic just as the whole world in early 2020.
Following the implementation of the lockdown in Belgium, a decision was taken mid-March to drastically reduce the staff physically present at Coreso while Operations activities initially continued on-site, since Coreso is considered an essential and crucial service critical to the nation. This challenged us to adapt operational processes, IT infrastructure, shift organisation in less than 2 weeks to have more than 50% of the operational activities performed from home. It was an opportunity that arose to speed up remote access for a number of operational processes.
To perform the remaining activities that must be performed at Coreso premises, the operators worked in separate rooms, shift schedules were adapted from 8h to 12h, and offices were rearranged to be “COVID-proof”.
On 27 and 28 June 2019, Coreso organized and welcomed the 4th edition of the TWEET: TWEET stands for Tournament and Workshop of European Electricity Transportation at Brussels.
This was a good opportunity to bring together Transmission System Operators (TSOs) and Regional Security Coordinators (RSCs) to discuss current and future challenges and share a convivial moment on the field. After the football tournament, won by RTE Lille (congratulations!), participants attended a presentation about European challenges. This event ended with a visit of the European Commission.
On 5 July 2019, the Clean Energy Package (CEP) came into force, requiring Regional Coordination Centers (RCCs) to be built on the positive experience of RSCs. RSCs will therefore evolve into RCCs by mid-2022, leading to a series of evolutions regarding organisation, governance rules and procedures.
Under the CEP, the standard RSC services will be transferred to RCCs. The services that TSOs will identify in the future as necessary for regional coordination – such as the management of critical grid situations – and new tasks identified in the CEP will also become part of the RCCs’ portfolio, while other tasks mentioned in the CEP will only be part of the RCCs’ portfolio if delegated by the TSOs.
Under the title #PowerCoordinationEurope – “Think globally, Coordinate regionally and Act locally”, the second edition of the ElSeC (ELectrical SEcurity Coordination) conference was organised and hosted by ENTSO-E and Coreso, in partnership with the Florence School of Regulation and the Energy Post.
Over 250 participants from all of the different fields of the energy industry attended the conference. They contributed to the lively discussions throughout the day and had a unique opportunity to explore the European electricity ‘stellar system’ with its local, national,
regional and European dimensions, its market, operations, planning and innovation galaxies,
with IT as the vehicle connecting the dots between them.
An RSC working table was established in February 2018 as part of the regional power coordination perspective. Three different workshops were organized: the first in Munich on April 25th and the following ones in Copenhagen and Hamburg.
The managers of the five European RSCs met with the common goal of ensuring alignment between RSCs and providing support to the ENTSO-E RSC Project, focused on the delivery of the best possible service levels for the TSOs. The long-term goal is to have regular meetings with all the European RSCs in order to exchange views on common challenges.
These fruitful meetings represent the concrete output of earlier discussions between Coreso and TSCNET Services with regards to the enhancement of inter-RSC coordination and RSC cooperation on development issues. They are an illustration of the fact that enhanced cooperation between RSCs will be key to reaching our common target.
Eirgrid and SONI, the two grid operators on the island of Ireland have joined and become a shareholder in Coreso, the coordinating body for regional security. They join their European counterparts from Belgium (Elia), France (RTE), the UK (National Grid), Italy (Terna), Germany (50Hertz), Portugal (REN) and Spain (REE).
Spanish high-voltage transmission system operator (TSO) REE is now a shareholder in Coreso, joining TSOs from Belgium (Elia), France (RTE), the UK(National Grid), Italy (Terna), Germany (50Hertz) and Portugal (REN).
REN, the Portuguese TSO, is joining the ranks of Coreso’s current shareholders, its fellow TSOs Elia (Belgium), RTE (France), National Grid (United Kingdom), Terna (Italy) and 50Hertz (Germany), by becoming a new shareholder.
The European Awareness System is established: technical implementation of the EAS (ENTSO-E Awareness System) at Coreso (read access via the RTE connection to EAS) is completed. Coreso can now also view the most important real-time parameters for the European electricity system.
Renewables data provision: Along with a renewable energy data provider, Coreso now has a view of both wind and solar generation forecasts across all of Continental Europe and Great Britain.
The ‘operational back office’ role of Operations Engineer is created. Operations Engineers are mainly responsible for supporting the operational team and helping management to guarantee that Coreso operates efficiently.
Support in the event of major disruption. Coreso launches a new service to help its shareholder TSOs in the event of major disruption. Coreso operators have access to several sources of real-time information (remote access to the SCADAs of its shareholders and DADS). As such, they have a more extensive overview when monitoring the grid than individual TSOs and can anticipate Europe-wide issues.
Terna and 50hertz join Elia, National Grid and RTE in Coreso. Coreso extends its coordination services to its new shareholders. Read more information.
Coreso starts operating 24/7 with experts hired from participating TSOs at its Brussels-based centralised coordination centre. Coreso provides virtually real-time security analyses in addition to day-ahead forecasts. Studies are completed based on so-called real-time ’snapshots’ supplied by TSOs. Computational models provide results every 15 minutes that are used by expert engineers to assess the security of the European electricity system. Read more information.
Great Britain TSO National Grid joins Elia and RTE in Coreso. Each of the three TSOs – Elia, RTE and National Grid – now holds one-third of Coreso’s capital. Read more information.
Coreso launches its operational activities in a centralised coordination centre in Brussels. Every afternoon, seven days a week, Coreso provides forecasts of electrical flows in the CWE area (France, Belgium, Germany, the Netherlands and Luxembourg) for the following day (so-called ‘D 1 activities’). Read more information.
Coreso (COoRdination of Electricity System Operators), the first regional technical coordination centre for electricity bringing together several TSOs, is incorporated by French transmission system operator (TSO) RTE and Belgian TSO Elia. Read more information.
A Memorandum of Understanding (MoU) is signed by the German, Belgian, French, Luxembourg and Dutch governments and the actors involved (TSOs, power exchanges, regulators, market players) in support of the regional CWE initiative. The Memorandum of Understanding aims to introduce market coupling between the CWE electricity markets and improve coordination between TSOs to ensure security of supply in Europe.
Following serious electrical power disruption in Europe 15 million people are left without power due to a lack of coordination between Transmission System Operators (TSOs) in the Central Western Europe (CWE) area. The European Commission, together with TSOs, starts looking into ways to improve coordination between TSOs to guarantee the safe operation of the interconnected system with a view to maintaining security of supply.
