As a Regional Coordination Centre (RCC), Coreso is responsible for implementing and executing six coordination tasks (namely CGM, CSA, CCC, STA, OPC and Defence & Restoration Plans) foreseen by the European network codes in the Third Energy Package. Adopted in 2009 by the European Union, this Package aims to liberalise and integrate Europe’s energy markets. It marked a turning point for Coreso, shaping our role and activities as an RCC and establishing the first six coordination tasks that underpin our operations today.

Common Grid Model
(CGM)

TSOs produce mathematical models representing the national grid, including details about topology, generation, and load characteristics. As energy does not stop at the borders, it is crucial they exchange information and collaborate across borders to ensure the security of electricity supply at European level.

To create a common view, Coreso and the other RCCs collect these individual grid models and merge them into one European representation of the high-voltage electricity network: the Common Grid Model. We consistently check the quality of the input and provide recommendations to enhance the output, as the Common Grid Model forms the basis for all our other coordination services.

Region: Pan-European level.

Coordinated Capacity Calculation
(CCC)

Large volumes of energy are exchanged across European borders to allow the best use of available generative resources and to operate the electricity system more efficiently.

To facilitate cross-border power exchange, Coreso calculates and provides the maximum cross-border capacities that can be allocated to the market while ensuring the security of the grid. Using a secure energy platform, this allows market parties to optimise electricity exchanges, especially in case of energy surplus or scarcity.

Regions: Core, Italy North, South-West Europe, Central Europe, and Swiss Northern Borders CCRs.

Coordinated Security Analysis
(CSA)

The European transmission network is highly interconnected. As a result, security constraints in one area have the potential to impact the entire network.

Through the Coordinated Security Analysis task, Coreso performs analysis aimed at detecting operational security violations on the grid and proposes to TSOs the most efficient and cost-effective remedial actions to limit and solve potential issues.

Regions: Core, Italy North, South-West Europe, Central Europe, and Swiss Northern Borders CCRs.

Short-Term Adequacy
(STA)

Power generation based on clean energy alternatives is difficult to predict as it’s subject to the forces of nature: sunny weather and windy circumstances may therefore lead to excess power generation, or – vice versa – create shortages when the sun doesn’t shine or there’s a lack of wind.

With the Short-Term Adequacy task, Coreso detects situations where a lack of electricity generation is expected, suggests and coordinates solutions for TSOs to enable them to respond effectively to demand in due time and guarantee generation meets consumption.

Region: Pan-European level.

Outage Planning Coordination
(OPC)

The European transmission network covers thousands of kilometres of power lines across the continent. Infrastructure of this magnitude is prone to maintenance works to keep the network safe and functional. These interventions need to be planned very carefully, requiring close coordination between all TSOs since local actions in one area can have significant and possibly problematic effects on neighbouring areas.

With the other RCCs, we collect and merge the unavailability plannings provided by each EU TSO. Our role is then to identify potential inconsistencies or incompatibilities in these plannings to prevent these from leading to outages or compromising grid stability. If any, we propose and coordinate solutions for TSOs to ensure the security of electricity supply across Europe.

Region: Pan-European level.

Defence & Restoration Plans Consistency Check

Preventing grid incidents is of course the number one priority, but when they do happen, preparation is key. That’s why TSOs develop Defence & Restoration Plans, containing relevant procedures to restore the grid as soon as possible in case of emergency, blackout or restoration states.

As an RCC, Coreso reviews and compares TSO’s individual plans to identify potential inconsistencies and propose mitigation actions.
