What are Triad periods?
What are Triad periods?
What are Triads? The Triad refers to the three half-hour settlement periods with highest system demand between November and February, separated by at least ten clear days. National Grid uses the Triad to determine TNUoS charges for customers with half-hour metering.
What are triads in energy?
What are Triads? Triads are the top three half-hourly peaks of national energy demand across the grid, separated by ten clear calendar days, over the most energy intensive period of the year: November to February. National Grid confirms these peaks after the season, at the end of March.
How is Triad calculated?
Based on the average consumption for three half-hourly periods between November 1st and February 28th, Triads are calculated using the three periods when the network is operating at its highest loads.
How do Triad charges work?
Triad charges relate to National Grid’s transmission charges. They measure maximum demand readings three times a year and use the average of these readings to calculate Transmission Network Use of System (TNUoS) charges. Triad charges are only applicable for half hourly metered sites.

How are periods and groups arranged on the periodic table?
Periods and Groups Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. Periods Rows of elements are called periods. The period number of an element signifies the highest unexcited energy level for an electron in that element.
When did Mendeleev create the 17 group periodic table?
Mendeleev’s periodic table of 1869 contained 17 columns with two partial periods of seven elements each (Li-F & Na-Cl) followed by two nearly complete periods (K-Br & Rb-I). In 1871 Mendeleev revised the 17-group table with eight columns (the eighth group consisted of transition elements).
When did Dobereiner discover the triad of three elements?
By 1829, Döbereiner had found other groups of three elements (hence “triads”) whose physical properties were similarly related.
