Issue 2 | Why should a PTA consider energy efficiency and CO2 emissions even though energy costs are supposed to be paid by the TOC?
Although energy costs are usually supposed to be borne by the TOCs themselves, there are several reasons why PTAs should address the energy efficiency of the rail operations within their scope:
- In some networks of the European railway system, the consumption of electric traction energy is not charged according to actual consumption, or the costs are borne directly by the contracting PTA.
- Current energy prices do not sufficiently reflect the urgency of climate protection or risk of future shortages of energy supplies. New railway vehicles will usually last for three or four decades. If their energy consumption is high, this will result in future additional costs.
- Cost calculations of bidding TOCs focus on the first period of operations (usually not more than 1/3 of the vehicle's lifetime). The energy costs of later decades are neglected and thus provide risks for public finances in the future.
The energy consumption of railway operations is influenced, to a substantial extent, by the condition of the infrastructure and the timetable concept. The PTA often has decisive influence on these determinants.
