In the current natural gas supply system, the regional transmission network (RTL network) is the connecting link between the national high-pressure transmission network (HTL network) and the distribution networks. Like the HTL network, the RTL network extends across virtually every region of the Netherlands. In terms of its role, the RTL network has a strong similarity to the provincial road network, which also extends across almost the entire country and provides the connecting link between the national motorways and municipal roads.
The report describes the current functions of the RTL network. It also briefly considers important differences in the spatial footprint of transporting energy through the regional gas transport system and through the regional electricity transport system. The report then explores how the role of gas is expected to change over the coming decades and what this means for the RTL network.
The conclusion is that the RTL network will continue to fulfil its role as the connecting link in the gas supply system. The strategic value of this network to the energy system as a whole will increase as the energy transition progresses and the centralised, top-down natural gas system is gradually replaced by decentralised production of biomethane.
