Everything you need to know about Triads

||

What is a Triad?

Triads, consist of the three half-hourly peak periods of national electricity demand, identified in March but based on the previous November to February figures. There must be at least ten days between individual Triads, to avoid a cluster over a short period. This could mean that a Triad is actually chosen, which was initially considered less likely.

They typically occur during cold weather, when high business demand meets the domestic mid/late afternoon tea-time period, causing an overall spike in energy use.

They are a charge that pays for the upkeep of the Electricity Transmission Network, which moves energy from generation to the local Distribution Networks.

Who pays Triads?

Triads are used to calculate charges for those who have half hourly (HH) meters. This tends to be industrial and commercial customers. The charge is proportional to a business’ energy use over the Triad periods and is linked to their location.

How do they affect my business?

Triads make up about 7% of your electricity bill and are built into your HH meter contract as a fixed fee or a pass-through element, which is reconciled retrospectively.

Because it’s retrospective, your energy supplier will, where contractually possible, calculate the difference between what they estimated the charge would be and what it actually was, resulting in a charge or a credit on your Electricity invoice.

Why is being aware of Triads helpful?

If you have HH metering, you can receive email notification when a Triad is likely to occur. In the last ten years, 50% occurred on Monday, 23% on a Thursday and 73% between 17:00 – 17.30.

It can be useful to be aware of Triads when looking at future pricing and arranging new energy contracts. Suppliers will use your historical Triad data in their pricing, so the lower your energy use at these times, the better.

Pass through contracts are set up, so that if you use more energy than expected in the Triad periods, this will result in a one-off additional cost, so consider fixing this charge for more budget certainty.

Being aware of potential Triads can allow you to shift the time of an energy intensive processes or harness onsite generation, to lower Triad costs. This also reduces the Distribution Network charges, some of which are also based on when you use Electricity.

What’s next?

From April 2022, Triads will likely be replaced as part of the, Targeted Charging Review. Timescales for this have already moved and there remains a lack of clarity as to the final details.
