Explicit Auction Capacity

About

The Explicit Auction Capacity chart shows the levels of capacity declared to be available for explicit intraday trading between Great Britain and neighbouring markets (France, Netherlands, Belgium).

As of the time of writing this only allowed for trading to/from France, the Netherlands and Belgium.

These volumes allow for any intraday movement of power and National Grid will often be active in this space to trade through other countries or to manage changes in interconnector flows.

Included Data

Explicit auction is when the transmission capacity on an interconnector is auctioned to the market separately and independently from the market. This contrasts to implicit auctions where power flows automatically based upon the differences in prices in each of the bordering markets.
