Point is the 8 months payback delay is calculated taking for granted there is a high-performance electricity storage unit. This unit cost and even existence has not been taken into account in the payback delay. For now, there is no high-performance storage units anywhere in the world, hence its cost should be then infinite since the technology to build them is not there yet.
Otherwise, the study should take into account the cost of integration with the existing grid and the variation costs of other energy suppliers when the wind farm is supplying the grid. This cost is higher than you may think. This study is bullshit anyway.
