Triads: were you caught out?

National Grid has now published the Triads for winter 2016/17, confirming the three half-hourly periods where demand was highest on the system. These periods will be used to calculate the cost of TNUoS. Inenco’s Triad team correctly predicted all three Triads and sent warnings to businesses to make sure they reduced non-critical consumption – Lorcan Anglin, head of demand reduction at Inenco, takes a closer look at the Triads and what they mean for business energy.

Last winter, most businesses were caught out by the unusual occurrences of Triads, taking place outside the more frequent 5pm – 6pm periods or at the very edge of the Triad season. There was a great deal of speculation about the influence that businesses were having by implementing demand management measures or acting on Triad warnings. The common belief was that as businesses continued to invest in demand-side management, Triads would become increasingly difficult to predict and eventually we would probably see a complete overhaul of the Triad system.

National Grid has now published the triad dates for winter 2016/17 and, surprisingly, these dates have reverted to the previously predictable patterns – all the triads happened between 5 and 5:30pm, two occurred on Mondays (statistically the most common date) with the third on a Thursday (statistically the second most common date) and all dates were in December and January:

Monday 5th December 2016 | 17:00pm – 17:30pm | 50,163 MW chargeable

Thursday 5th January 2017 | 17:00pm – 17:30pm | 48, 516 MW chargeable

Monday 23rd January 2017 | 17:00pm – 17:30pm | 48,970 MW chargeable
