Getting to grips with TRIADs; How TNUoS charges affect your electricity bills

Share Article

Energy Solutions are set to launch a new TRIAD warning service, but what exactly are these charges, and what can businesses do to reduce their impact on the bottom line? Our new Triad / TNUoS alert service will let you know when national electricity demand is at its highest, and you can save significantly by reducing your consumption for less than 1 hour.

Triad charges relate to National Grid's transmission charges

Triad Charges

Triad or TNUoS charges can have a significant impact on your energy spend.

Next year many businesses will receive a Transmission Network use of System (TNUoS) or Triad charge on their bill. For large users, this can represent more than 5% of the total bill, but represents just 90 minutes of usage. This charge levied by the National Grid for the maintenance of the electricity transmission system – the transformers, pylons and cables that crisscross the country. TRIADs are the three half-hour periods of peak demand that occur between November and the end of February. Ofgem rules require that TRIADs be separated from the last by at least ten days.

Rather than calculating this charge based on actual use of the network over a whole year, TRIADS give the National Grid a way of measuring supply and demand at times when the grid is most heavily used. How much a business pays depends on their portion of network use, at this time. This can be great for seasonal businesses that are busy in the summer, but not so good for those experiencing a winter rush.

TRIADs typically occur in the evening, when it is dark and cold and businesses are still consuming power. Weekdays between 5 p.m. and 5:30 p.m. are prime times. However, the National Grid will not know which TRIAD period has seen peak demand until it looks back at the entire TRIAD period at the end of February.

It is important to understand that TRIADs can affect any business and that although they cannot be eliminated, their impact can be significantly reduced.

Energy Solutions has developed a number of tools that can help businesses track potential TRIAD dates. By monitoring the National Grid, Energy Solutions can warn energy users about potential TRIAD periods, allowing them to reduce or shift demand. This TRIAD management usually involves reducing consumption for a few hours during periods when peak demands are forecast.
