TRIAD Dates Confirmed | 2017/18
Winter 17/18 TRIAD dates
The results of the 17/18 TRIAD season were today confirmed by National Grid:
Monday 11th December ’17 - SP35
Monday 5th February ’18 - SP36
Monday 26th February ’18 - SP37
These three periods are only confirmed by National Grid retrospectively once settlement data has been reviewed.
For the first time, two events occurred in February owed mostly to the cold spells at the start and end of the month. Traditionally, TRIAD events are most common on Mondays and the trend continued this season with each event occurring at the beginning of the week.
Predicting the time of TRIAD is becoming an ever more challenging task. This year, perhaps due to the uptake in demand side response (DSR), peak demand was suppressed initially before surging in a subsequent settlement period. DSR results in approximately 2GW of demand being removed from the transmission system mainly due to reducing load and onsite generation.
