Future Railway Power Supply

Bane NOR Energi, Planning dept. Nils Grønneberg 2017-02-02 Bane NOR Energi’s assignment

Ensure an adequate and stable railway power supply at the correct voltage and frequency.

Sounds simple…

…but we can’t do it without a lot of help from others!

We will see a number of projects in the next few years, which directly affect our railway power supply.

2 Railway network undergoing development

The section maps of the future will look different.

NTP 2018 – 2029 is aggressive: • More people to travel by train • Environmentally-friendly transport • Significant increase in capacity • Higher frequency of departures • Significant reduction of travel time

This means: • More sections • New tracks on the sections • More double track • Electrification

3 Consequences for railway power supply

Factors with a direct effect: • Increase in passenger traffic – new timetables • Increase in freight traffic • New rolling stock • Increasing power required • Modernisation of overhead contact line system (with autotransformers)

Action by Bane NOR: • New systems must be constructed • Existing systems must be upgraded • Maintenance must be intensified • New studies, master plans and analyses of load flow and stability
