Locational Heat Map

Customers that connect at Extra High Voltage (EHV) will incur Distribution Use of System charges that are dependent on their location.  Where the Electricity North West network is underutilised and there is spare capacity available, EHV customers can expect the locational element of their use of system charge to be low.  Where the Electricity North West network is fully utilised and there is little spare capacity available, EHV customers can expect the locational element of their use of system charge to be high.

The PDF file below contains a heat map which shows the amount of spare capacity that is available on the Electricity North West network and provides an indication of the locational charge that will be applied at each primary substation.  The heat map has been coloured to represent the level of the locational charge as follows:

  • Red:      Locational Charge greater than 13 £/kVA
  • Amber: Locational Charge between 5 £/kVA and 13 £/kVA
  • Green:   Locational Charge less than 5£/kVA

To see the locational charge that applies within an area, Adobe Acrobat needs to be in dynamic selection mode, which can be achieved by selecting Edit/Analysis/Object Data Tool.  Once this option has been selected, the locational charge can be viewed by clicking on the area in question.
