TNUoS transmission fees and preparing for the Triad period

The three periods of high demand can mean big bills. Luckily, we're here to help maximise cost savings.

22 September 2015

Customers and generators pay transmission fees (TNUoS) to National Grid each year in order to maintain and upgrade the UK electricity grid. The amount you have to pay is calculated by monitoring your usage during the period 1 November – 28 February - the Triad period.

What is the Triad period?

The Triad is the term used to describe the 3 periods during any given year when National Grid anticipate overall demand to be highest. This will equate to the three highest half hour (HH) settlement periods between 1 November and 28 February, separated by a clear window of 10 days between each. Historically Triads have occured most often between the hours of 5pm and 6pm, as industry and domestic power usage tend to peak, however they have on occasions been outside this window. 

Being prepared for a Triad period is essential as your usage during these periods can significantly impact the transmission charges that you subsequently have to pay. Speak to your power supplier to make sure they can offer Triad warning services and help you manage usage during these periods to maximise cost savings.

In all likelihood, most of our business energy customers won’t notice when TNUoS transmission fees are incurred during the Triad period. However, some businesses, particularly ones that use a large volume of electricity, may be charged at a higher rate during a Triad period.

To alleviate the financial strain of paying transmission fees, we’re able to provide warnings which alert you of an upcoming Triad period. These alerts could give you enough time to reduce the amount of electricity you use and therefore avoid paying transmission fees, although this isn’t guaranteed.

By cutting down on your energy use, you’ll effectively reduce our overall electricity demand on the National Grid — which will in-turn help us to reduce the amount we charge your business.

Sign up to our Triad warning service, and you’ll receive alerts throughout the winter (when demand is at its highest) — giving you plenty of opportunities to reduce your electricity consumption.
