We’ve now entered the Triad season, in which your TNUoS charge will be determined by the electricity consumed across three peaks in national demand across the months November to February..

Over the coming months we will issue warnings which highlight potential half hourly peaks, so that you can reduce demand where possible to minimise the impact of this cost.

What are Triads?

The three half hour peaks in UK demand between November and March, which must be at least 10 days apart.

Why are they important?

The Triad programme aims to smooth out peaks in UK demand during winter. Your sites will be charged based on the average consumption across the three peaks (Triads).

Why respond?

Reducing your electricity consumption during these periods can drastically limit the TNUoS cost which makes up around 10% of non-commodity costs.

Brownlow aim to issue no more than 20 warnings each year, in a bid to call each Triad and give you the opportunity to reduce consumption and reduce this cost.

Here's an example below -

Going forward the Triad charging mechanism will change but for 2021-22 it is firmly in place!
