Gasunie has two main activities: (1) providing transport services through the gas transport network in the Netherlands and Germany, and (2) providing other infrastructure services. Our infrastructure interconnects suppliers and end users of energy as an international hub in the supply and transit of natural gas. For this purpose, we manage and develop gas infrastructure and gas trading platforms: gas transport networks, international transit pipelines, gas storage, gas infrastructure and virtual gas trading platforms. This enables us to contribute to a liquid, competitive and reliable European gas market. We also apply our knowledge and experience of energy infrastructures and markets to enable and accelerate the energy transition.
Gas transport in the Netherlands is provided by Gasunie Transport Services (GTS), and in Germany by Gasunie Deutschland (GUD). We are a state-owned company and the Dutch State is our only shareholder. Our employees are spread across more than 30 sites in the Netherlands and northern Germany, and we also have representation in The Hague, Brussels and Moscow. Our headquarters are in Groningen (the Netherlands), and our German head office is in Hanover.
Revenue regulation in the Netherlands and Germany
Gas transport services in the Netherlands and Germany are regulated. The rates are calculated by dividing the permitted revenues for a specific year by the forecast capacity bookings for that year. The permitted revenues consist of a capital cost allowance for the invested capital, a reimbursement for the annual depreciation costs and a reimbursement for the operating costs. The actual energy costs of gas transport are recovered by means of a (partial) settlement mechanism.
If the actual volume of bookings and corresponding revenues differ from the forecast, the difference is settled in subsequent years. The rates are determined once annually by the regulatory authorities, who review the method of regulation every 3 to 5 years. The regulatory authority in the Netherlands is the Authority for Consumers & Markets (ACM), and in Germany it is the Bundesnetzagentur (BNetzA).
The other infrastructure services, which are either unregulated or partially regulated, are provided by our Participations business unit. This business unit runs the projects focused on existing infrastructure and renewable energy solutions, developed by the Corporate Business Development department.
