Historic Substation Demand Curve

Listed in spenergynetworks

The " Historic Substation Demand Curve " data table provides the historic half-hourly demand (MW) for the last three years for the SPD and SPM license areas.

Description

These tables have been published to give the users information which will allow them to better understand the demand throughout the years. The file gives the following information: Substation Name – A unique identifier for the substation.

Median Demand (MW) – The median half-hourly demand value for each of the last three years. Voltage – The voltage tier at which the substation operates. Weekday – The day for which the median demand has been calculated.
