The work primarily involved the construction of the wind turbine foundations and installation of the turbines using two cranes. [...] Other work included improvements to the access roads for transportation of the turbines to the site, construction of a substation and an operations and maintenance facility, and cabling for the substation and electrical collection system. [...] The main drivers of centralised procurement and choices of suppliers by the OEMs relate to the scale of the procurement programme, the price, and warranties, and trusted relationships with suppliers. [...] Plastic Polymers are used in the wind turbine and are additionally used together with aluminium, copper and steel in the production of cables for the plant. [...] Copper Copper is predominantly used in the coil windings in the stator and rotor portions of the generator, in the high- voltage power cable conductors, transformer coils and earthing.
