Triad Flyer
Find out more about Triad season and our Alert service download our flyer here.
The Triad season runs from 1 November to the end of February. Three half hour periods during this phase are used to calculate transmission charges for the entire year by National Grid. This is part of the Transmission Network Use of System (TNUoS) scheme. If your electricity contract allows it, reducing your demand at these specific points will result in lower transmission charges. However, knowing when Triads occur is a complex business.
To help our clients, EIC provides a Triad Alert service. We have successfully forecast each of the three Triad periods for the last 7 years. By predicting Triads each winter, EIC has saved customers millions of pounds in transmission charges.
