According to Article 2(21) of the Commission Regulation (EU) 2017/2195 of 23 November 2017 establishing a guideline on electricity balancing, ‘TSO-TSO model’ is a model for the exchange of balancing services where the Balancing Service Provider (BSP) provides balancing services to its connecting TSO, which then provides these balancing services to the requesting TSO.
TSO-TSO model means a model for the exchange of balancing services exclusively by Transmission System Operators (TSOs). In the TSO-TSO model all interactions with a BSP in another responsibility area are carried on through the connecting TSO. The TSO-TSO model is the standard model for the exchange of balancing services.
- a TSO-TSO model, and
- a TSO-BSP model (where a BSP has a contractual relationship with another TSO than its connecting TSO).
It was decided that the European integration model for a future EU-wide balancing market should be based on a TSO-TSO model, where TSOs covers all cross-border processes and obligations (if not delegated to a third party).
According to Article 29(7) of the said Commission Regulation (EU) 2017/2195 of 23 November 2017 the activation of balancing energy bids is to be based on a TSO-TSO model with a common merit order list.
