Control the clock change in an instant

Control the clock change in an instant

The end of British Summer Time will see UK clocks turn back 1 hour on Sunday 28 October. This will cause a significant shift in consumption on the electricity system as evenings turn darker, earlier. What’s different about this year?

The seasonal trend towards higher demand during the colder, darker winter months will accelerate as a result of the clock change. This will place pressure on power margins and could lead to spikes in electricity prices, should supplies struggle to meet the higher demand.

Energy demand will jump but the downward trend continues

Current forecasts indicate the peak demand for the week following the clock change will be 9% higher than the previous week. Consumption is set to increase by nearly 4GW to more than 45GW overall as an earlier sunset (around 4:30pm) increases lighting requirements during the traditionally higher post-work demand period. If so, this would be the highest percentage change on record, with the 3.8GW rise nearly three times larger than the demand bump seen in 2015 or 2014.

However, the ongoing trend in reduced energy consumption has continued, meaning that demand is rising from a far lower base. Expected demand before this month’s clock change is 6GW lower than the most recent peak in 2015.

Furthermore, the expected post-clock change peak is the lowest on record.

*Forecasted figures

Improvements in energy efficiency have been reducing electricity use for the last 10 years. A large part of the reduction in peak demand has been the use of new smart technology, resulting in more efficient appliances that are able to do more with less. A switch away from incandescent light bulbs is also a contributing factor, particularly during the winter months, when lighting demand plays a far increased role in consumption.

weekly power demand

Aside from a well-documented cold snap in February and March (remember the Beast from the East?) peak demand during 2018 has been largely below that of previous years, continuing a consistent year-on-year reduction in consumption overall.

React to changes in real-time with smart building controls

How can you ensure time-consuming but critical processes affected by the clock change are carried out efficiently?

IoT controls can help you alter site settings remotely, so you’re in full control when the clocks change. There’s no need to make arduous manual changes – with IoT, you can make the necessary changes at the touch of a button.

With our Building Energy Management solution, we’re introducing the next generation of smart building controls. Developed in partnership with Vodafone and Dell EMC, our solution brings together the required technologies to integrate all your critical energy systems. This enables your business to access real-time insights on key energy and building systems via single, remotely-managed platform.
