How to Tackle Triads this Winter to Reduce Your Half Hour Electricity Bills

by Simon Thompson

During the winter months, business and domestic users tend to use much more energy, including half hourly electricity. To manage this demand, the National Grid uses Triads to encourage businesses to reduce their energy consumption at peak times.

If your business is reliant on half hourly electricity prices then it is important to understand Triads and how they work, as they can have a huge impact on your electricity bill.

What are Triads in electricity?

The National Grid uses Triads to calculate how much half-hourly metered businesses will pay for their energy use over the winter months.

Triads are the name for the three half-hour periods during the winter that tend to see the most energy usage. They can happen on any day from the 1st of November to the end of February, however, they must be at least 10 days apart so that they don’t fall on consecutive days.

They usually also take place between 5 pm and 6 pm as this tends to be when energy consumption peaks for both domestic and business users – but Triads can sometimes fall outside of this window.

How do electricity Traids affect business energy bills?

Electricity Triads only affect businesses who use half-hourly electricity, which tends to be businesses that are of medium or large size.

One of the most significant costs these businesses will see on their energy bills – aside from commodity costs – is the Transmission Network Use of System (TNUoS) charge that is paid to maintain the electricity transmission system in the UK.

If your business receives half-hourly electricity bills, then your total TNUoS charge for the following year is calculated based on the amount of energy your business uses in the three half-hour Triad periods.

So, if your business tends to use a lot of electricity, ensuring you optimise your usage during the three Triad periods can make a huge difference to your annual spend. The more you can reduce your electricity consumption during the Triad periods, the lower your TNUoS charges will be for the rest of the year.

How can you reduce your Triad-related business electricity costs?

Despite the uncertainty, there is over exactly when Triads occur, there are certain things you can do to minimise their impact:

  • Optimise your business hours and energy consumption to minimise energy usage during the Triad period, perhaps by turning off non-essential machinery or using an on-site generator instead. You need to do a cost-benefit analysis before you do this though, to make sure any savings you may potentially make will outweigh the incurred costs
  • Treat every day as if it is a Triad day. Regardless of when Triads occur, you can keep your energy usage to a minimum every day by turning off lights that aren’t in use so that you don’t get hit by spikes.
