(25)

Back up Diesel Generator

• Energinet.dk will install one diesel generator on each of the platforms to back up the supply for the platform

• The diesel generator will not be dimensioned for emergency supply to the wind turbines, only for back-up supply to the platform

• No space has been allocated on the platform for a diesel

generator to provide back-up supply for the wind farm when the

220 kV connection onshore is out of service

(26)

Concession owner

• The platforms have been prepared for various WFO equipment

• Main equipment among others:

Wind park control panels, Fiber junction boxes,

Meteorological systems, 33kV MV switchgear, antennas etc.

• Preliminary WFO equipment list – with equipment which the

platforms are prepared for will be supplied to the bidders along

with a pdf copy of this presentation

(27)

Location of array cables

• Orientation of J-tubes on KFA shown below:

Location of array cables

• Orientation of J-tubes on KFB shown below:

(29)

J-tubes

J-tube size:

• 33kV Array cables min. ID 350 mm Dist. between hang-off:

• Min. 1000 mm

Bell-mouth restrictions:

• Min. 1500 mm between bell-mouth Additional info:

• Concrete wall to end of bell-mouth min. 500 mm

• Bell-mouth to existing seabed 500 mm (expected)

• 33kV J-tubes are allowed to have one additional bend besides the main bend from vertical to horizontal (approx. 75

degree), the bend may not exceed 25 degrees

(30)

Access and installation aids

• Access and installation aids for routing of 33kV will not be available

• The expected minimum elevation difference between cellar and

main deck is app. 7.5 m

(31)

Concession owner scope for 33kV cable routing/support

• The WFO owns, pays, operates and maintains the 33kV cable routing including support

• KFA and KFB have been designed with a 33kV cable routing and layout to fit the platforms

• Single line diagrams according to Appendix 6.1

• WFO can for his own expense alter the 33kV routing/layout in

corporation with the fabrication yard, as long it does not interfere

with the HV cable routing (220kV)

(32)

33kV MV switchgear

• MV switchgear must be delivered at topside fabrication yard September 2017

In case concession owner is found late:

• ENDK will handle the tendering of the switchgear, except for protection relays

• The switchgear contract will be assigned to concession owner

when he has been appointed

(33)

Design and certification

• The detailed design for the topside is concluded and is being certified as we speak. In other words the design is locked and cannot be changed

• The substructure has been concept designed and will be tendered

as an EPCI contract

Market framework for Kriegers Flak B2B

KF AC information meeting

Søren Klinge

(39)

framework

Framework agreed between 50Hertz and Energinet.dk

Approved by the Danish Energy Regulatory Authority on the 29

^th

of January 2014

The off-shore grid at Kriegers Flak will be allow for both off-shore wind and cross- border interconnection.

The project is co-finansed by the European Commission’s Economic Recovery Program

This presentation is Energinet.dk’s sole responsibility

^Kontek

(40)

Market design – main principles

• Prioritized access for off-shore wind to the national Danish on-shore transmission grid

• The Danish off-shore wind park at Kriegers Flak will be an integrated part of the price area in Eastern Denmark

• Capacity not used for transport of off-shore wind to the on-shore grid will be used for cross-border trade in the day-ahead market coupling and intra-day markets

• The capacity for cross-border trade is

calculated on the basis of the “net-of-wind”- principle. The capacity will vary between 0 and 400 MW.

• Same conditions for trading in day-ahead and intra-day markets as for any other Danish off-shore wind park

1 Year Wind

Market

(41)

Market design – main principles # 2

• Capacity calculation will be based on the TSO’s forecast of wind power

• Capacity will be given to the day-ahead market following the procedure for the market coupling

• The available capacity on Kriegers Flak will be given to the market together with the

existing interconnector Kontek between Eastern Denmark (DK2) and Germany

• Energinet.dk is financially responsible for settlement of all cross-border transactions

Market design – operational principles

• Outages: Conditions for continued production will have to be defined at a later stage.

• Any consumption of electricity by the Danish off-shore wind parks for stand-by purposes during periods of

outages on the radial connections to the Danish onshore grid will have to be settled with Energinet.dk.

• The framework for the balancing market contains a minor special condition concerning netting of imbalances with on-shore production facilities in some situations.

• A detailed description of the market framework can be

found in the appendix to the final tender documents

available at DEA’s webpage.
