Infographic: Triad Reconciliations

Energy explained - InfographicTRIAD Reconciliation

The TRIAD period runs between November and February, the official dates are released by the National Grid in March each year and are based on the 3 highest peaks of demand during this period (Nov-Feb), taking into account the ‘10 clear day rule’.

To factor these TRIAD charges into what business are invoiced, suppliers estimate what a business is likely to consume during these peak periods and charge accordingly throughout the year. The TRIAD charges a business pays in advance are held until the actual TRIAD periods are released.

Once the dates are announced, suppliers will review these published periods to check that the invoiced charges over the year cover these charges and will reconcile as needed. The reconciliations appear on customers’ invoices between April and June and can be in the form of a credit or additional charges.

If businesses were able to avoid the TRIAD periods over the course of the winter period then they will probably see a credit on invoices, however, if they did not take action or were unable to avoid the warning periods then they will probably see an additional charge on their reconciled invoice.

Estimated Triad periods for 2020/2021:

7th Dec 2020, 17:00 – 44,353 MW

7th Jan 2021, 17:30 – 45,328 MW

10th Feb 2021, 18:00 – 44,886 MW

Our Triad alerts correctly predicted all three winter 20/21 triad periods.
