Triad season

Triad season presents opportunity to reduce future bills

It’s back!

Triad season is upon us.

The annual game of “guess the date” that determines part of your business’ energy bill is now underway.

Triad season runs from November to the end of February and is used to determine the strain put on the UK’s transmission network.  This determines the TNUoS (Transmission Network Use of system) charge that is applied to the non-commodity part of your energy bill.

How it works

A usage reading is taken from all half-hourly meters.  The three highest readings (that can be no fewer than 10 days apart) taken during that four-month period are defined as the Triads and determine the TNUoS charge.

They usually fall when industrial demands meets domestic meal time around the early evening, 5-6pm.

Why should my business care?

This presents an interesting opportunity.  If your business can correctly predict the Triads, you can ensure your usage is at an absolute minimum at those times, hence reducing your future TNUoS charge, which is applied per meter.

A decent starting place for preparing for this would be last year’s confirmed Triad periods.  They were:

22 November 2018 (17:00)

10 December 2018 (17:00)

23 January 2019 (17:30)

How to use this to your advantage

Prepared businesses, usually larger ones, are already strategically preparing a load-shedding schedule around these times.  They’ll also usually utilise some form of prediction service to help them with alerts ahead of likely triad times.  Sign up to our prediction service for 2019/20 here:

We can help advise you on a strategic load-shedding schedule to minimise service disruption and consumption at this key time of year.  Get in touch for some advice from our Energy Management Team.

Remember, the TNUoS does only form part of your energy bill.  But, in our uncertain economic climate, every cost saving is important to businesses.
