Modeling has also shown that it's relatively inexpensive to increase the reliability of the total wind output to a level equivalent to a coal - fired power station by adding a few low - cost peak - load gas turbines that are opearated infrequently, to fill in the gaps when the wind farm production is low (Diesendorf 2010).
