Issue 6 | Reference level of consumption and service profiles

When the PTA can provide a reference level for energy consumption, the integration of energy efficiency in the award process can become more effective than without such a reference. The reference shows realistic data on the energy consumption of specific operations. Depending on its function in the award process or contract, it can take the shape of

  • a maximum value;
  • a target value; or
  • an average value.

In other words: Reference values help to define an interval of plausible energy consumption values / reduction potentials.

The energy consumption of specific railway operations depends on the infrastructure conditions, ambient conditions, timetable and other operational requirements. These conditions must be clearly defined if offers of bidding TOCs or manufacturers are to be compared consistently. For this purpose, specific or standard service profiles should be used.
