Our responsibility extends beyond Germany’s borders: we connect Europe by expanding our transmission grid to neighbouring countries. We help to operate Europe’s interconnected grid safely and efficiently. And we are working with partners to further develop Europe’s internal electricity market.
Amprion is particularly committed to making the transmission of electricity around Europe efficient. The staff at the System Operation and Control Centre in Brauweiler coordinate the electricity flows between the national grids in the northern section of Europe’s extra-high-voltage grid.
The power supply industry in Europe has changed massively over the past 25 years. Step by step, the national electricity grids are developing into a close-meshed interconnected grid that transports electricity generated in power plants and traded on exchanges across Europe. To this end, Amprion makes its own transmission grid available as a physical platform. In order to be in a position to coordinate this exchange of energy effectively, Amprion has an indirect stake in the European Power Exchange EPEX SPOT in Paris and also in the “Joint Allocation Office” in Luxembourg, an auction platform that offers long-term transmission capacities for trading. In addition, the company ensures that this combined system of electricity trading and interconnected grids functions efficiently. The staff members at Amprion’s System Operation and Control Centre in Brauweiler handle this and coordinate the electricity flows between national grids in the northern section of Europe’s extra-high-voltage grid. This “northern block” stretches from the Netherlands in the north-west to Romania in the south-east of Europe.
Europe’s power supply industry is facing major challenges: more and more electricity is coming from renewable energy sources whose feed-in varies greatly depending on the time of day and the weather. In addition, the volumes of electricity being traded on the exchanges and exchanged across national borders are rising. This makes system operation and control an increasingly demanding task. “As staunch Europeans, we want to make the interconnected grid even more capable and efficient and further develop Europe’s internal electricity market,” says Joachim Vanzetta, System Operation and Control Manager at Amprion. This is being done, for example, under the umbrella of the European Network of Transmission System Operators for Electricity or the international symposium on the development of extra-high-voltage grids in Paris.
Amprion’s task is and remains to operate its own grid safely and stably. To achieve this, we have to keep a close eye on the grids of our European neighbours, too. The corresponding “monitoring area” includes, among others, the Benelux countries, parts of the French grid, Switzerland and northern Italy. Amprion’s system operation and control staff identify critical grid situations early on and can react to impending bottlenecks by coordinating with colleagues across borders. This is facilitated by international partnerships. The Munich-based “TSO Security Cooperation”, founded and operated by 12 European grid operators, provides cross-border analysis of grid situations and calculates transmission capacities available for trading – to make sure electricity is always delivered to where it’s needed, right across Europe.
Amprion connects electricity markets across borders
Amprion - Belgium
ALEGrO, the first power bridge between Germany and Belgium, is set to commence operations in 2020. Preliminary planning for a second connection is now under way.
Amprion - Luxembourg
Two cross-border power lines link the Amprion grid with Luxembourg. The supply capacity of the interconnector from Heisdorf to Niederstedem is scheduled to be increased in future.
Amprion - France
The existing link from Vigy to Uchtelfangen is scheduled for future reinforcement.
Amprion - Switzerland
Three interconnectors currently link the Amprion grid with Switzerland. The power line from Beznau to Tiengen is planned for future expansion.
Amprion - Austria
Currently three power lines cross the border between the Amprion control area and Austria. The interconnectors between Bürs and Vöhringen and between western Tyrol and Leupolz are scheduled for future reinforcement.
Amprion - Netherlands
The new pipeline from Wesel to Doetinchem went into operation in September 2018, increasing the number of interconnectors to four. Amprion is in charge of three of them.
Europe is seeing convergence in the energy sector, too. Amprion is building cross-border lines, known as “interconnectors”, to connect our power grid more closely with those of our European neighbours. A new power bridge linking Wesel and Doetinchem in the Netherlands went into operation in 2018. Interconnectors such as this one are intended to make the grids safer and electricity cheaper across Europe as a whole. If, for instance, a power plant in Germany has to be disconnected from the grid unscheduled, others power utilities in Europe can supply the necessary electricity via interconnectors. What’s more, this internationally available power can be transported right across Europe via the cross-border connections.
