Triad Alerts

For large electricity consumers, the ability to reduce your electricity consumption during periods of national high demand in the months November to February inclusive can lead to a reduction in electricity transmission costs for the following year. The three highest 30 minute periods of demand in the UK over these four months are known as TRIAD periods and are used to calculate your transmission charges for the following year.

These three periods are only known after the four months and as electricity consumption cannot be dropped retrospectively, there are services that can help estimate the days where national demand is likely to be high. We offer a free notification service to our electricity consumers via email and text message throughout the 4 month period to help our customers reduce their transmission costs where possible.

Please contact your Total Gas & Power account manager to register for this service.
