For organisations with half-hourly (HH) metered sites, identifying the annual Triad periods is crucial

National Grid identifies three Triads each year in order to calculate the Transmission Network Use of System (TNUoS) charges an organisation will incur. Such transmission costs can be reduced if demand is decreased when a Triad is expected. Our Triad Alerts help clients plan their electricity usage around these dates in order to lower their energy bills.

What is a Triad?

  • A Triad is one of the three highest peaks of electricity demand between 1 November and the end of February.
  • These half-hourly periods normally occur between 4pm and 6pm on weekdays.
  • There must be at least ten days between individual Triads – this means consecutive days of high demand will not yield multiple Triads.

Why choose EIC?

We have an enviable track record in Triad prediction. In the 2017/18 season we accurately identified all three Triads, only issuing our highest level of alerts (Red) nine times during the entire period. For the latest season, those that took action in response to our alerts cut demand by an average of 15% compared to standard peak-period half-hour consumption.

By forecasting when Triads will occur, we empower our clients to take control of their consumption and reduce their energy use in order to avoid higher Triad-related charges. Businesses can respond simply by reducing demand during that time or by load-shifting.

Load-shifting involves moving the most energy intensive tasks of the day to a time when it’s less likely that a Triad will occur, for example early in the morning. Load-shifting means firms can avoid Triads without reducing their overall daily usage.

We can provide you with the tools you need to take swift action and react to Triad warnings with our Intelligent Buildings suite of services.
