HS1 traditionally consumes around 240GWh of electricity per annum. Approximately 79% of consumption is through three traction sites which have their own grid supply points. The remaining 21% of consumption is split between the stations, depots and ancillary sites such as switch rooms and signal boxes. The load is reasonably flat throughout all seasons and weighted 87:13 on a day/night basis. Most sites have existing unallocated Available Supply Capacity (ASC) and the business has a close relationship with the incumbent DNO (UKPN).
