Compressor stations are part of the gas transport system and they are necessary to keep the pressure constant when gas is being transported over long distances. As gas is transported through the pipeline, the pressure drops which leads to a reduction in capacity. That’s why the pressure must be increased approximately every 100 kilometres in order to make it possible to transport greater volumes of gas at the correct pressure. Compressor stations supply compression (pressure and capacity). Gasunie has 22 compressor stations.
