Does temperature impact the System Price?

Thomas Demetriades in ELEXON’s Market Analysis team, investigates how the temperature influences the System Price. The article includes visualisation graphics that you can interrogate to get a better understanding of the data behind the analysis.

The analysis shows that when we feel more extreme temperatures (temperatures greater than 25°C or lower than 5°C) the system is Short in 66% of Settlement Periods. July 2018 was a particularly warm month, with the average GB noon temperature being 22°C. We source the GB average noon temperature, used for setting profile coefficients, from the Met Office.
