Triad energy storage benefits

How did the triads affect electricity use?

The Triads often had the effect of reducing peak demand at certain points in the winter months. That’s because electricity users turned down their use when they estimated demand would be highest (and therefore likely to become one of that year’s Triads) in order to avoid paying extra TNUoS.

What are triads & how do they work?

What are Triads? The Triads are the three half-hour settlement periods of highest demand on the GB electricity transmission system between November and February (inclusive) each year, separated by at least ten clear days. National Grid uses the Triads to determine TNUoS locational demand charges for customers with half hourly meters.

What impact did triads have on major power users?

Triads were three half-hour, peak periods during the winter that saw the highest demand for electricity. “Tri” refers to the three periods, while “AD” stands for average demand.

How much power does a triads use?

Here’s how to do it: In this example, the average consumption over the Triads is 6666.66kW. This is the volume you will be billed for. Where can I find historical Triads data?

Why is Triad demand falling?

This is a continuation of a trend that’s seen the average Triad demand drop by almost 17% in the past ten years. Two of the Triads this winter saw their lowest level of demand ever, perhaps because of very high electricity prices, of increased energy efficiency, or of both. It’s not just the Triads that are seeing a fall in demand.

Do you pay nil triad?

Many areas now pay nil triad, as TNUoS has become part of the standing charge. Distribution Use of System (DUoS) also changed from April 2022, increasing fixed daily charges and reducing volume-based charges. You would need to get in touch with the site’s DNO, which you can find on the Energy Networks website.
