ALEGrO
➔ First HVDC-interconnection between BE (Elia) and GE (Amprion)
➔ European priority project
➔ 100 km underground cable between Lixhe(BE) and Oberzier (GE)
➔ Transmission capacity of approx. 1000 MW
➔ Operational 2019
ALEGrO : main characteristics of the project

Timing Scope
Budget
➔ 94 km underground cable link between Lixhe (BE) and Oberzier (GE) (49 km BE / 45 km GE)
➔ Transmission capacity of approx. 1000 MW
➔ Applied DC voltage: +- 320 kV
➔ Applied convertor technology: VSC multilevel symmetricmonopole
➔ Applied cable technology: HVDC XLPE cable
➔ Reinforcement works in Lixhe ( extra bays GIS + TFO )
ALEGrO: main focus areas in 2017

• Start detailed engineering converter and cable in order to start the production on time (Valves,
TFO, cable, …) and to finalize the CW design (building, tunnel, …)
• Type tests cable (started on 22/02/2017, end expected by July 2017)
• Start cable production (foreseen Q3/2017)
• First delivery of cable (FAT) (foreseen Q4/2017)
• Start of application procedure according to PCI-regulations (started on 20/02/2017)
• Permits Belgium:
o Introduction of the permit file (20/02/2017)
o Public consultation (May-June 2017)
o Obtaining the global decision on the permits (December 2017)
MOG: the Modular Offshore Grid
The strategic importance of the MOG in a further offshore griddevelopment
13
The MOG will create valuable advantages for Belgium’s positionin the future offshore development:
• Readiness for more offshore production in Belgian waters: Additional wind mills on existing concessions, additional concessions, other power sources.
• An electric node in place for a link to 380kV grid via another route than Stevin (e.g. cable to Doel)
• A forward base for future interconnections:Connection to Dutch offshore grid, new interconnector with the UK, first Belgian building block of the future offshore supergrid.
• MOG can be built for a similar cost as the sum of individual connections that would be needed
• Greater robustness than individual connections:MOG’s 3 cable redundancy will convey more energy to shore
= yearly the equivalent of 10.000 additional households consumption.• Modular build-up:
synchronization with OWP’s planning : limits risk of stranded assets.• Smaller impact on the environment:
shorter total cable length: +/- 160 km vs 200 km
These future advantages will be achieved without an additional cost for the community.

Project description
23
• National Grid and Elia are developing an electrical interconnector (1000 MW HVDC) between the UK (Richborough) and Belgium (Zeebrugge‐Herdersbrug).
• The interconnector will allow electricity to flow in either direction between the two countries. • Nemo will be regulated through the ‘cap and floor’ regulatory regime• It will collect congestion revenues through explicit and implicit capacity auctioning mechanisms
• Commercial operation is scheduled for Q1 2019• Estimated total project budget for construction : € 721 million of which 50% for Elia• Elia System Operator will therefore take a 50% stake in NemoLink; NGIH will take the other 50%
