TenneT has delegated several regulated activities of an operational nature to subsidiaries.

The daily auctions are still organised by TSO Auction.

EnerQ B.V. (in liquidation)

The activities of EnerQ ended on 1 January 2009. The company was dissolved with effect from the same date. This is the result of the Minister of Economic Affairs' decision to transfer the implementation of the MEP grants scheme to SenterNovem with effect from 1 January 2009.

Foundation for the Management of Allocated Funds from the National High-Voltage Grid

This foundation (in Dutch: Stichting Beheer Doelgelden Landelijk Hoogspanningsnet) was established as a trust office to manage the allocated funds received by TenneT in its capacity as administrator of the national high-voltage grid through performance of its statutory duties. These allocated funds comprise proceeds of imbalance settlements and auction receipts. TenneT TSO B.V.'s allocated funds are intended for specifically designated purposes.
