2 MW is nowhere near enough, even for such a tiny community.
They mention the batteries in the video above. The video also mentions that one site has five turbines with a combined rating of 4.5MW and that there are 500 turbines on the island. These are pretty small turbines (some turbines are rated at 8MW each!) and he actually mentions the capacity factor (31500 hours producing 14000 MWh) so the average production is .44MW. Assuming they are all these small turbines, with similar average production, they are getting about 220MW of power from wind, with a peak capacity of 450MW.
A gusty day could fully charge those batteries in well less than a minute, a calm day would drain it just as quickly.
