MeyGen Phase 1A15MW Grid Connection – Project Status

1212

Existing 33kV Line Thurso to Laurel

33kV Line from Laurel to HastigrowConductor Upgrade

Hastigrow 33kV substation upgrades

COMPLETE

18km of 33kV cable installed

14.9MW 33kV connection at Ness of Quoys –Substation built and switchgear installed


MeyGen Phase 1A15MW Grid Connection – SHEPD

• MeyGen Connection Agreement in place since 2010 – early investment crucial

• Classified as “Large Power Station” and required to meet Grid Code –electrical interface with Onshore Works Contract

• Dedicated room within building designed and built to house SHEPD substation – physical interface with Onshore Works Contract

Onshore Building, SHEPD Room – 33kV Switchgear Installed

17km of Onshore 33kV Onshore Cabling completed

MeyGen Phase 1AOnshore Works – ABB

• Onshore Civil Works Completed

• SHEPD room completed and Handed Over for Grid Connection

• Electrical Fit out work commenced

• Building designed to minimise noise and visual impact

• Designed to reliably dissipate heat from electrical conversion equipment

Onshore Building – South and West Elevations



Onshore Building – Power Conversion Units (PCU) Installed. The PCUs provide torque control to the turbines (Interface with both Turbine Contracts) and convert power to Grid Code compliant quality (Interface with Grid)

Onshore Building – Overhead Cable Management System



Control Building – Installation of 33kVtransformers (left) and LVAC switch board(above)


MeyGen Phase 1AHorizontal Directional Drilling - OCU

Horizontal Directional Drilling – 4 x 570m Bores completed (Interfaces with Cable Supply, Onshore Works and Offshore Works Contracts)


MeyGen Phase 1ASubsea Cable Design and Manufacture - JDR

Cable Supply Contract –Completed Design andManufacture of 11.5km ofsubsea cable (Interfaces withTurbines, Offshore Works andOnshore Works)

MeyGen Phase 1AOffshore Cable Installation - JFMS

Mobilisation of Offshore Construction Vessel (Siem Daya) at Hartlepool


MeyGen Phase 1AOffshore Cable Installation - JFMS

Installation of 11.5km of Cable Offshore

• Offshore Cable Installation Works Completed

• Bespoke cable laying operation - specific neap tide selected and one 2.5 km cable installed every 12 hours

• Total operation at MeyGen Site completed in 2.5 days

• Interfaces with Cable supply Contract and HDD ContractAtlantis Resources: May 2016

MeyGen Phase 1ACable Installation - JFMS

Subsea cable being pulled through HDD to Onshore Site

• Cables pulled through HDD bores with enough length to connect directly to building

• 24 hour operation co-ordinated with Offshore Lay

• Post-Installation cables tested from Onshore to confirm successful install

MeyGen Phase 1ATurbine Support Structure (TSS) Detailed Design- RBG

23

Detailed design of TSS completed

Tank Testing of TSS

Ballast Block Detailed Design

• Design Life of 25 Years

• Two different TSS designs – design interface with both turbine supply contracts

• Turbine and Substructure is one dynamic system

MeyGen Phase 1ATurbine Support Structure (TSS) Ballast Blocks- JGC

24

• 16 of 24 Ballast Blocks completed

• Each Ballast Block weighs 200 Tonnes

• Each Substructure has 6 Ballast Blocks – total Ballast weight 1200 Tonnes

• Most cost effective design uses steel plates “as cast” and bolted together.

• Design life of 25 years required steel plates to be cladded to prevent water ingress. Ballast Blocks at JGC Fabrication Facility in

Janetstown, Thurso.

MeyGen Phase 1ATurbine Support Structure Fabrication - GEG

• All fabricated steel forfour TSS has beenprocured and deliveredto Nigg

• Inner Sections of allfour TSS substantiallycompleted

• In the process ofassembling the outerlegs

• Interfaces with bothTurbine Suppliers forstructural stabs andcable managementsystems
