The diagram shows the scheme for transmitting electrical power from an offshore wind farm, Wind Generation G, to an onshore industrial manufacturing park, Industrial Consumer I.

Explain the stages of this transmission system that ensure electrical power is delivered efficiently from Wind Generation G to Industrial Consumer I.
Your answer should explain the physical roles of Offshore Substation T1 and Onshore Substation T2, and how transmission through Subsea Cables C is optimised to minimise power losses.
