History repeats itself – trends are hard to change.

All three Triads this year fell on a Monday.

As well as being possibly the worst day of the week, Mondays are the most common day for a Triad period to occur with 36% of Triads falling on this day.

In fact, 60% of Triads have been on either a Monday or a Thursday, the second most likely day (24%).

When there’s snow…watch out!

The late cold snap in February means that for the first time we have two Triads in the last month of the season. What should we take away from this? When snow disrupts the UK, don’t let it affect your load and Triad management because temperature is the biggest single factor for determining when a Triad will fall.

The graph below shows when the three Triads fell this year with the daily minimum temperature for each day highlighting the dramatic dip in temperatures at the end of February.

Triad Season Dates 2017-2018

Later in the season = later in the day

For the second time in three years and the second time only, we have a Triad falling in the half hour from 18:00-18:30. This is due to the influence of later sunset times as we get further into February. In 2016, the 18:30 Triad fell on 15th February whilst this year was on the 26th.

If you are only able to shift load for a limited time each day, then expect to focus on the hour between 17:30 and 18:30 as we move into February each year.

How low can we go?

This is the first time this millennium that each Triad has a demand below 50 GW, the last time this occurred was 1998/99. This can be only good news as we move toward a smarter network.

Since 2008, we’ve seen a gradual decline in the UK’s Triads. An average downward trend as more consumers drive efficiency and seek off-grid solutions.
