From the article: “When the final two turbines are commissioned at Granville Harbour, Tasmania will have access to 10,741 GWh of renewable generating capacity – well above our average annual electricity demand of 10,500 GWh,”

How do they determine renewable generating capacity? I'm asking because it will vary years to years. Is it the theoretical max, or is it the value based on some averages of the expected output?

You use a combination of local measurements (over a year) and historic weather data (over decades) combined with the specifications of your generator to estimate output. That model gives you an expected generation in an average year, amongst other things.
