# The Awel y Môr Offshore Wind Farm Order 2023, Paragraph 2: Offshore design parameters

Extent: E+W

(1) The wind turbine generators to be constructed or operated as part of the authorised development must be located within the area delineated by the co-ordinates in Table 2 and shown on sheet 2 of the works plan and, subject to any lighting approved under requirement 3, there must be no material difference in the size and appearance of the wind turbine generators.
