— Better wind resources
— Reduced social impact: NIMBY
— Large potential
— Investment potential:
• 1 – 3 billion euro per wind farm
• banks consider offshore wind as a mature
technology offering competitive financing

17. Foundation
17
— Monopile foundation
• Up to 30-40m water depth
• Most often used in offshore wind farms
• Tubular steel structure
• Driven into seabed with hydraulic hammer
• Transition piece (grouted) to connect tower
• Scour protection to prevent erosion of the
seabed
• Heaviest monopile today:
— 1 300 ton
— 7,8m diameter
— 83 m long

18. Foundation

19. Foundation
19
 Gravity based foundation
— Concrete construction
— Applied for < 30m water depth
— Less used for new offshore projects
— Very heavy (up to 3000 ton)
— Need a lot of space and time
— Seabed needs to be prepared
carefully

20. Foundation
20
 Jacket foundation
— Lattice structure grouted on anchor piles
— 4 anchor piles driven in seabed
— Relatively light (500 ton)
— Fast fabrication
Transition piece

 Offshore Transformer Station
(OTS):
— 33/150kV transformers
— Switchgears
— Shunt reactors
— Emergency diesel generator
— Emergency shelter
— Power controllers
— Heli-hoist deck
— Weight: 1000 – 2000 ton
— Power: 200 – 800 MVA

40. Offshore wind at Engie

41.  18 years of experience in ENGIE offshore Wind
development teams going back to 1998 (Seanergy
project)
 Cofely-Fabricom experienced in Offshore Maintenance
Services (E&P + offshore wind Netherlands)
 ENGIE Fabricom is a market leader in OHVS for offshore
windfarms (~50% market share)
— 12 built
— 19 awarded
— capacity to build from 5-7 substations at the same time
ENGIE offshore wind experience & competences
41

42.  Tractebel ENGIE (incl. IMDC) provided development
support, engineering & construction Follow-up of
Thornton bank project
 Offshore wind projects in development (with partners):
— Mermaid: 250 MW in Belgium
— Le Tréport & Noirmoutier: 2 x 500 MW in France
— WindFloat Atlantic: floating wind, 25MW in Portugal
— Pre-development of floating project in French Mediterranean

43.  Does ENGIE want geothermal power plants in its portfolio?
 If so, what would be ENGIE’s strategy to accomplish this given the unfavorable risk profile?
 Is ENGIE able to compete with current operators/owners?
 How to increase ENGIE’s competitiveness?
 How Metier CenGen can help achieving this objective?
