Methodology to determine the regulated asset base of the network

Source: International Energy Agency
Last updated: 05 September 2025
The Belgian energy regulatory (CREG) has established a methodology for calculating the value to be included in the regulated asset base in the event of the purchase by the hydrogen transport network manager of a pipeline for which there is already a valid transport authorisation. The CREG methodology for valuing existing pipelines acquired for hydrogen transport in Belgium is based on the fair value principle. This means the value included in the regulated asset base (RAB) is determined primarily by the price paid for the asset or its fair market value, reflecting the economic benefit the asset provides in its current or optimal use. The methodology applies only to acquisitions of pipelines with valid transport permits, including those under the 1965 gas law. The methodology is effective from 1 August 2024
