Offered reserve capacity used for other purposes
TenneT has established a single-buyer market for regulating and reserve capacity
in order to perform its tasks in the area of transmission and system services. On
this single-buyer market, market parties can offer regulating or reserve capacity
to TenneT. This concerns surplus capacity that market parties produce over or consume
under the volumes reported in their E Programmes.
TenneT uses this reserve capacity to resolve transmission restriction and to provide
assistance to other countries.
- The Grid Code contains
stipulations regarding the compulsory and voluntary provision (by means of bids)
of regulating and reserve capacity to TenneT.
- The Implementation Regulations describe
the procedures and the specifications that bids must meet, as well as the calculation
method for the settlement price.
- The Grid Code and
the System Code also
contain provisions regulating the use of bids by TenneT.
- A bid for reserve capacity for other purposes states the conditions (minimum dispatch
time, minimum dispatch duration and price) under which the market party is willing
to let TenneT enter into a transaction with said market party for the volume of
capacity on offer. The transaction volume is settled with the bidder at the bid
- The transaction volume is corrected on the imbalance of the market party’s
The volume calculation is based on:
- The volume of the bid in MW
The direction (+/-) of the bid:
- Upward adjustment (+): the supplier wants to produce more or consume less
Downward adjustment (-): the supplier wants to produce less or consume more
- Duration of the transaction
TenneT TSO enters into transactions based on the volume of offered reserve capacity
for other purposes, in each direction according to the demand and in bid price order.
