TenneT uses a system of balance responsibility to keep the supply and demand of electricity in check. Connected parties are responsible for informing grid administrators of their planned electricity production, consumption and transport needs. If their actual consumption and production differs from what they forecast, imbalances occur, which can ultimately affect the reliability of the grid.
The parties can set up these programmes themselves, or assign the responsibility to authorised programme responsible parties.
Why is balance responsibility necessary?
Participants in the Dutch electricity market are free to choose who they trade with. Suppliers and consumers enter into contractual agreements that stipulate how much power they are buying and selling (supply instructions and blanket orders). In practice, the agreed amounts can differ from what they actually produce or consume. These discrepancies must be settled so no power shortages or surpluses occur. TenneT uses a system of balance responsibility for this.
How does it work?
Authorised programme responsible parties (PRPs) inform TenneT daily about their planned transactions for the next day, and the networks they will use for transporting the electricity. The sum of the transactions for each PRP is called an energy programme (e-programme).
The regional grid operators inform us about how much electricity each PRP actually consumes and produces. The difference between the amounts in the e-programme and the actual measured values is the imbalance.
Programme responsible parties
TenneT recognises two types of programme responsible parties: those with full recognition and those with trade recognition. Full recognition means they also have balance responsibility for grid connections.
To be authorised by TenneT as a programme responsibility party, applicants must:
- have the required technical and administrative expertise, including of how to submit the electronic E-programmes
- issue a financial guarantee
- enter into an agreement with TenneT
