MingYang also celebrating its aquaculture in action. Each unit catches 10000 fish, which makes the offshore turbine even more economical
do some math, each fish brings in $5 in revenue. Each catch brings in $50000
you bring it in 3 times a year, that's additional $150k in revenue generated by each turbine.
read this, the economics of offshore wind in China is pretty hard to beat.
It looks like fish farming typically has a 40% profit margin
So if there are 30K fish in a year @ $5 sales price, that's $150K in revenue yes
But the annual profit is only $42K
If you look at a 16MW offshore wind turbine and go with a 42% capacity factor and sells electricity at 5cents/kWh, that's $3 Mn in revenue.
So whilst an integrated fish farm is still worth doing because the platform is already there, it doesn't look like such a small scale fish farm makes too much difference to the financials. But if they can scale this up 10x, then it would start to make a big difference.
