The electricity supply is transmitted along separate systems in the Netherlands and Germany. TenneT is responsible for connecting electricity producers to the high-voltage grid. We also ensure the transmission of electricity across this grid. TenneT does not distinguish between producers and is obliged by law to connect all parties to the grid, from coal-fired power plants and wind farms to small-scale horticulturalists.
TenneT is the sole transmission system operator (TSO) of the national high-voltage grid of the Netherlands. In Germany, TenneT is the biggest TSO among the 4 TSOs, connecting the North Sea with the Alpes.
We are therefore responsible for a number of additional tasks that may not be performed by other grid operators in the Netherlands. This includes system services (e.g. maintaining the balance between electricity supply and demand) and ensuring the security of supply. TenneT also acts as a market facilitator, ensuring that all players in the industry have access to the market.
In Germany, TenneT performs the same tasks, alongside three other TSO's, who each cover their own designated areas. What makes TenneT's role in Germany particularly challenging is its obligation to connect and transport electricity generated by offshore wind farms to the onshore high voltage grid.
In order to perform our diverse and various tasks, TenneT works closely together with the following parties:
- ACM (NL) and the BNetzA (DE)
- Grid operators
- Balance Responsible Parties (BRPs)
- Electricity producers
- Traders in electricity
- Parties with metering responsibility (NL)
- TSO organisations (ENTSO-E members)
