First cables of ALEGrO installed

27.09.2019

The “Aachen Liège Electricity Grid Overlay” (ALEGrO) will be the first direct interconnector of the German and Belgian electricity grids. Its transmission capacity of 1,000MW is going to significantly increase cross-border electricity flows and security of supply in the regions surrounding the new converter stations at the respective ALEGrO end points, Niederzier in Germany and Lixhe in Belgium. The European Project of Common Interest (PCI) is jointly being implemented by TSCNET shareholder Amprion, one of the four German transmission system operators (TSOs), and the Belgian TSO Elia.

In the summer of 2019, several teams were working simultaneously at different points along the 41km-long ALEGrO section in Germany on the installation of the conduit system for the underground cables. Underground cabling is used exclusively for the entire German-Belgian power bridge. Due to the dry summer, construction work on the DC link has progressed rapidly: 60 percent of the cable conduits have already been completed. Amprion is now beginning to pull the 320kV cables successively into the conduits, initially in Niederzier, where the construction of the new ALEGrO converter plant is also progressing well.

Significant progress for ALEGrO

03.05.2019

October 2018 saw the start of construction of ALEGrO, the “Aachen Liège Electricity Grid Overlay”, which is the first direct interconnector of the German and Belgian electricity grids. With a transmission capacity of 1,000MW, ALEGrO will increase cross-border electricity flows and, at the same time, supply security in the western German region of Aachen-Cologne. The European Project of Common Interest (PCI) is realised jointly by TSCNET shareholder Amprion, one of the four German transmission system operators (TSOs), and the Belgian TSO Elia. Only a few months after the start, Amprion can already report some great strides in the construction work.

Underground cabling is used for the entire ALEGrO route (approx. 49km in Belgium and 41km in Germany) and two new converters are being installed at each end of ALEGrO at the substations Oberzier in Germany and Lixhe in Belgium. The coordination effort for the German-Belgian power bridge, which crosses numerous roads, waters or forests, is considerable: Explosive ordnance clearance and the demolition of remnants of world war bunkers are daily business, but of course archaeological investigations and nature conservation are also part of today’s construction standard.

Several teams are working simultaneously at different points along the route in Germany, laying cable conduits into which the conductor cables will later be drawn. 5km of the conduit system have already been completed and 25km are currently under construction. At the Oberzier substation, a hall is currently being erected to house the converter technology. Work is also proceeding well in Belgium, and according to current planning ALEGrO should be operational by the end of 2020.

ČEPS: Solid finances and major investments

15.04.2019

The high revenues from cross-border capacity auctions and the higher than expected earnings from system services and transit flows were the main contributors to the successful business year 2018 of TSCNET shareholder ČEPS, the Czech transmission system operator (TSO). The company’s profit of CZK3.307bn (about €129m) before tax represents an increase of 14% in comparison to 2017. The total amount of energy transmitted through the Czech high-voltage grid has risen to 65,825 GWh, with a peak load of 11.964MW in February 2018.

ČEPS has also maintained its high level of investment: The TSO expended more than CZK3.8bn (about €148m) in the further development and modernisation of its transmission system. The most important ongoing investment projects include European Projects of Common Interest (PCIs) like the new 400kV double circuit line from Kočín in southern Bohemia to the Mírovka substation near Havlíčkův Brod in the Bohemian-Moravian Highlands, or the interconnections between the 420kV substations at Vernéřov (Karlovy Vary Region), Vítkov (Moravian-Silesian Region), and Přeštice (Plzeň Region).

Also worth mentioning are the modernisation and expansion of the Kočín substation, which is an important node of the transmission network and due to be completed in 2023, the start of construction for the modernisation of the Horní Životice substation in the Moravian-Silesian region and finish of upgrading the gas-insulated, metal-enclosed Chodow substation in Prague. These and other projects are part of the TSO’s long-term investment programme, the implementation of which is made possible by ČEPS’s stable financial position, strict cost control and good financial performance.

Construction start for ALEGrO

30.10.2018

As a responsible and future-conscious transmission system operator (TSO), TSCNET shareholder Amprion is committed to the European Energy Union. An outstanding project in this respect is the Aachen Liège Electricity Grid Overlay (ALEGrO), the first interconnector to directly connect the German and Belgian electricity grids. The European Project of Common Interest (PCI) is being implemented jointly by Amprion and the Belgian TSO Elia. Following a pleasingly short approval procedure, the starting signal for ALEGrO was given today in the commercial area of the west German city of Aachen. Here, Amprion celebrated the start of construction with a symbolic turning of the first sod.

The ceremony was attended by numerous high-level representatives from politics, business and public life, among them Armin Laschet, Minister President of the German state of North Rhine-Westphalia, who commented: “ALEGrO is a milestone for cross-border power supply and not only connects North Rhine-Westphalia and Belgium, but also brings Europe closer together.” Dr. Klaus Kleinekorte, CTO at Amprion, complemented: “ALEGrO becomes part of the EU’s electricity highway system, which links the centres of renewable energy generation with the major consumption centres in Europe.”

For the entire ALEGrO route (about 49km in Belgium and 41km in Germany) underground cabling will be used. The cable laying work is accompanied by the installation of converters at the ends of the cable in Oberzier in Germany and Lixhe in Belgium, which convert AC into DC and vice versa. ALEGrO will have a transmission capacity of 1,000MW and thus provide urgently needed grid capacities for cross-border electricity flows. At the same time, ALEGrO will also strengthen supply security in the Aachen-Cologne region.

SINCRO.GRID contract for process technical systems

16.10.2018

The Croatian-Slovenian smartgrid project SINCRO.GRID is carried out by the two TSCNET shareholders ELES, the transmission system operator (TSO) from Slovenia, and HOPS from Croatia. The cross-border initiative aims at optimising the efficiency of the Croatian and Slovenian electricity transmission grids through the application of advanced technologies and innovative data processing methods. SINCRO.GRID has been awarded the status of Project of Common Interest (PCI) by the European Commission under the Connecting Europe Facility (CEF) programme.

On behalf of SINCRO.GID, HOPS has signed a contract with KONČAR-KET, the Croatian provider of engineering services for power generation, transmission or distribution facilities. The contract comes with the rather unwieldy title: “Process technical systems for the voltage and reactive power regulation support of the EES and dynamic monitoring of the transmission line load within the SINCRO.GRID project”, but what it’s all about is to increase the quality and capacity of the power system through the use of advanced process technical systems and algorithms. This will also promote the integration of the renewables and increase the security of customer supply.
