438 EngineeringRail Power Supply 118 (2020) Heft 11 Impact of the energy transition on DC Rail Power Supply of The Netherlands Teun Ploeg, Arnhem (NL); Marcel Walraven, Fedor ten Harve, Utrecht (NL) ProRail, the rail infrastructure manager of The Netherlands has to face with a number of new developments. Some of them have a strong technological driver. Others are more political economical driven. These developments are all related with the energy transition. What impact will energy transition have on ProRail and its power supply network, and what can ProRail contribute? A specific methodical approach was used in order to identify relevant technological and policy questions. Auswirkung der Energiewende auf die DC-Bahenergieversorgung in den Niederlanden ProRail, der Infrastukturmanager der Eisenbahnen in den Niederlanden, muss sich einer Reihe neuer Entwicklungen stellen. Einige von ihnen haben starke technologische Treiber. Andere sind eher politisch-wirtschaftlich motiviert. Diese Entwicklungen hängen alle mit der Energiewende zusammen. Welche Auswirkungen wird die Energiewende auf ProRail und sein Energieversorgungsnetz haben und was kann ProRail dazu beitragen? Ein spezifischer methodischer Ansatz wurde verwendet, um relevante technologische und politische Fragen zu identifizieren. Impact de la transition énergétique sur l‘alimentation en énergie de traction à courant continu aux Pays Bas Pro Rail, le gestionnaire d‘infrastructure ferroviaire des Pays Bas, doit gérer nombre de nouveaux développements. Certains d‘entre eux ont une empreinte technologique fortement marquée. D‘autres sont plus motivés par les aspects politiques et économiques. Ces développements sont tous en lien avec la transition énergétique. Quel impact aura la transition énergétique sur ProRail et son réseau d‘alimentation en énergie de traction et comment ProRail peut contribuer? Une approche spécifique méthodique a été utilisée dans le but d‘identifier les sujets technologiques et politiques pertinents. 1 Introduction ProRail is the national rail infrastructure manager of The Netherlands. Its mission is to connect people, cities and companies now and in the future. Besides managing the rail infrastructure and railway-stations including maintenance and construction ProRail allocates the space on the track and controls the rail traffic. Since 1924 the Dutch railnetwork has been electrified with a DC 1500V system. Exceptions are the high speed line Amsterdam – Antwerp and the Betuwe-freight line from Rotterdam to Germany which are electrified with a AC 25 kV 50Hz system. About 500 km track has still not been electrified yet although electrification is still going on. Recent finished electrification project is the line Kampen – Zwolle – Wierden. Regional authorities are still considering electrification of their lines in northern part of The Netherlands, or to choose for other zeroemission options like hydrogen or accumulator trains. Figure 1 and Table 1 show the facts and figures of the Dutch rail power supply system. Two characteristcs should be emphasized. The Dutch rail power system have connections to the public grid. ProRail does not have a dedicated electric grid for connecting substations. Another characteristic is that ProRail has to comply with the Electricity Act of 1998. The rail power system is considered as a “closed distribution system” that is connected to a specific well defined group of consumers: railTable 1 Facts and figures of the Dutch rail power supply system. track length km 7146 length in exploitation km 3434 length elelctrified (DC) km 2161 substations 267 traction groups (transformer and rectifier) 453 track sectioning stations 110 energy transport (elctricity) GWh/a 1400 public grid connectios 204 gasoline 106 l 20
